  63. Four basic-tissues that make up the human body
    • Epithelial
    • Connective
    • Muscular
    • Nervous Tissue
  64. epithelial tissue
    the outer layer of mucous membranes and the cells constituting the skin. has a shortage of intercellular material, letting the cells form a tightly packed sheet, a protective quality
  65. Layers of epithelium
    • surface covering of the human body
    • all cavities of the body
    • tubes that connect cavities of the body
  66. Forms of epithelium
    • secretory
    • cilia
  67. cilia
    • -hairlike protrusions that actively beat to remove contaminants from the epithelial surface (beating ciliated epithelia)
    • -found in cavities of the respiratory passageway, within ventricles in the brain, lining of the central canal, etc.
    • -unique in that they are motile (their function involves movement)
    • -they move rapidly in one direction (returning to original posistion), and more slowly in the opposite direction (move materials from location to location)
  68. baseplate, or basement membrane
    • underlies epithelial tissue and made predominantly of collagen
    • function varies depending upon location (can act as filter or stabilize epithelial tissue
    • important in the process of directing growth patterns for epithelial cells
  69. The role of epithelial tissue
    to provide a barrier to some material (ex: can protect the skin from dehydration and leakage of fluid)
  70. connective tissue
    • composed of predominantly of intercellular material, known as the matrix, within which the cells of connective tissues are bound
    • may be solid, liquid or gel-like
  71. areolar tissue (or loose connective tissue)
    • elastic material found between muscles and as a thin, membranous sheet between organs
    • it fills the interstitial space between organs and its fibers form a mat or weave of flexible collagen
    • adipose tissue- areolar tissue that is highly impregnated with fat cells
  72. lymphoid tissue
    specialized connective tissue found in tonsils and adenoids
  73. fibrous tissue
    • binds structures together and may contain combinations of fiber types
    • -white fibrous: strong, dense, and highly organized. Found in ligaments that bind bones together, as well as in the fascia that encases muscle
    • -yellow elastic: found where connective tissue must return to its original shape after being distended, such as in the cartilage of the trachea or bronchial passageway
    • -collagenous and reticular fibers: provide a flexible structure to fibrous connective tissue where elastic fibers provide recoil to this tissue where needed
  74. cartilage
    • unique properties of strength and elasticity
    • tensile strength keeps the fibers from being easily separated when pulled
    • compressive strength lets it retain its form by being resistant to crushing
    • hyaline cartilage is smooth and has a glassy, blue cast for articulating surfaces of bones and in the cartilaginous portion of the rib cage
    • fibrocartilage contains collagenous fibers, providing the same cushion between the vertebrae of the spinal column, and mating surface for temporomandibular joint between the lower jaw and skull. acts as a shock absorber
    • yellow elastic cartilage has less collagen, endowed rather with elastic fibers. found in the pinna, nose and epiglottis
  75. blood
    • the fluid component of blood is plasma, and blood cells (red and white) are suspended in this matrix
    • blood cells arise from within the marrow of another type of connective tissue, bone
  76. bone
    • the hardest of connective tissues, and the hardness is a direct function of the inorganic salts that make up a large portion of bone
    • generally classified as being compact or spongy
    • compact: lamellar or sheetlike structure
    • spongy: looks porous. contains the marrow that produces red and white blood cells as well as the blood plasma matrix
  77. fibrobasts
    • responsible for the production of the extracelular matrix, so they are able to synthesize and secrete protein
    • another function is wound repair; infiltrating a wound site and laying down a matrix
  78. macrophages
    • another "healing" connective tissue
    • responsible for the collection of waste, bacteria or necrotic (dead) tissue, engulfing them and digesting them by secreting soluble proteins, which is critical in the regeneration of tissue
  79. lymphocytes (another important protective cell type)
    • B-lymphocytes arise from bone marrow and are stimulated to proliferate within lymph tissue by the presence of foreign matter. Generate and secrete antibodies to defend against viral attack
    • T-lymphocytes arise from bone marrow but end up in the thymus. their proliferation is stimulated by viruses, and their job is to seek and destroy viral agents
  80. mast cells (another important protective cell type)
    • found in loose connective tissues and some organs
    • provide the first response to irritation or inflammation
  81. muscle tissue
    • specialized contractile tissue
    • striated: (striped appearance under microscope) or also called skeletal muscle; known as voluntary or somatic muscle because it can move in response to conscious processes
    • smooth muscle: muscular tissue of the digestive tract and blood vessels; sheetlike with spindle-shaped cells
    • cardiac muscle: composed of cells that interconnect in a net-like fashion
    • smooth and cardiac are generally outside of voluntary control, related to the autonomic or involuntary nervous system.
  82. Nervous tissue
    • highly specialized communicative tissue.
    • consists of neurons or nerve cells that take on a variety of forms
    • funtion is to transmit information from on neuron to another, from neurons to muscles, or from sensory receptors to other neural structures
  83. organs
    tissue aggregates with functional unity
  84. Tissue Aggregates
    • fascia
    • ligaments
    • tendons
    • bones
    • joints
    • muscles
  85. Fascia
    surrounds organs, being a sheetlike membrane that can be dense or filmy, thin or thick. Striated muscle is surrounded by perimysium, fascia sufficiently thick (muscle can't be clearly seen through it)
  86. ligaments
    • "binding"
    • visceral: bind organs together or hold structures in place
    • skeletal: must withstand great pressure, typically bind bone to bone. the connective tissue fibers course in the same direction, giving ligaments great tensile strength
    • most ligaments have little stretch (with a white cast, those that stretch appear yellow)
  87. tendons
    • provide a means of attaching muscle to bone or cartilage (it's actually part of the muscle so it always binds muscle to another structure)
    • the fibers of tendons are arranged longitudinally (opposed to interwoven), giving them great tensile strength but less compressive strength
    • tendons tend to have the morphology (form) of the muscles they serve
    • aponeurosis: what a tendon is called when it is sheetlike. resembles fascia, but are more dense. will retain the longitudinal orientation of the connective tissue fibers, whereas fascia are made up of matted fibers
    • a tendon can withstand pulling of more than 8,000 times the stretching force that a muscle the same diameter can, or twice the pulling force of the muscle itself (a sudden pull will damage the muscle itself well before the tendon itself)
  88. bones and their relation to cartilage
    • developing bone has a portion that is cartilage and all bone begins as a cartilage mass
    • many points of articulation, or joining, between bones are comprised of cartilage. (cartilage will replace bone where elasticity is beneficial)
    • as cartilage becomes filled with inorganic salts, it begins to harden, ultimately becoming bone
  89. bones
    • provide rigid skeletal support and protect organs and soft tissues
    • 30% of bone is collagen, providing a great tensile strength
    • Calcium deposits contribute to rigidity and compressive strength of bone tissue
    • characterized by length (long or short) or shape (flat) or as having irregular morphology
    • periosteum: (fibrous membrane covering of a bone) extends long its entire surface (with excepts of regions that have cartilage) and is most tightly bound to the bone at the tendinous junctures. it is tough and fibrous, whereas the inner layer of periosteum contain cells that facilitate bone repair, fibrobasts
    • blood cell production occurs within the cavities of the spongy bone trabeculae (supporting beams) that are well protected by compact bone
    • the density of a bone and its conformation are directly related to the amount of force placed on the bone. (use of muscle causes bone to strengthen and become more dense in regions stressed by that activity)
  90. Joints, forms and the types of joints
    • defined: the union of bones with other bones or cartilage with other cartilage
    • forms and types:
    • diarthodial= high mobility. synovial joints
    • amphiarthrodial= limited mobility. cartilaginous joints
    • synarthrodial= no mobility. fibrous joints
  91. fibrous joints
    • Two major types
    • syndesmoses: bound by fibrous ligaments but have little movement
    • sultures: between bones of the skull that are not intended to move at all. several forms include; a serrate or denate (gains its strength from the jagged edge that mates the two bones together); a squamous where the two mating bones actually overlap in a "keying" formation; gomphosis which is a hole-and-peg arrangement (tooth) (socket); the plane joint is the direct union of two edges of bone
  92. cartilaginous joints
    • cartilage provides the union between two bones
    • synchondrosis: the cartilaginous union is maintained, although it ossifies as the individual ages
    • symphysis: found between the pubic bones or between the disks of the vertebral column
  93. synovial joints
    • include some form of joint cavity within which synovial fluid (lubricating substance) is found, and around which is an articular capsule (fibrous connective tissue covering). they are either simple or composite
    • plane synovial joints: gliding joints; arthrodial. the mating surfaces of the bone are more or less flat
    • spheroid (or cotyloid) joints are reciprocal in nature (as are all plane joints), in that one member of the union has a convex portion that mates with a concave portion of the other member. ball-and-socket joint. permits a wide range of motion

    • condylar joints: more shallow versions of the ball-and-socket joint and permit more limited movement
    • ellipsoid joints: are on a elliptical (football-shaped) member. Permit wide range of movement but not rotation
    • trochoid joint (pivot joint): designed for rotation. bony process protruding into a space
    • saddle joint (sellar joint): one member is convex, the other concave sitting on the saddle.
    • hinge joint (ginglymus): acts like the hinge of the cabinet door: one rotates on a joint with limited range, permitting only flexion and extension
  94. muscles
    • bound groups of muscle fibers with functional unity
    • epimysium surrounds muscles, and muscles have a tendon attaching it to skeletal structure
    • have a nerve supply to provide stimulation of the contracting bundle of tissue and a vascular supply to meet their nutrient needs
    • can contract to half its length, long muscles can contract more than short muscles
    • diameter of a muscle is directly related to its strength
    • muscles exert force by shortening the distance between two points and can contract only in a straight line (with exception of sphincteric muscles)
    • point of attachment of the least mobile element is the originpoint of attachment that moves as a result of muscle contraction is the insertion
    • agonist: muscle contracted for purpose of a specific motor act (as contrasted to the antagonist)
    • antagonist: a muscle that opposes the contraction of another muscle (the agonist)
    • synergists: muscles that stablilize structures
  95. More muscles
    • a muscle attached to a closer joint will move the bone farther and faster than the one attached farther from the joint. Thus the more distally placed muscle will have an advantage for lifting, while the muscle closer to the joint will provide greater range to the bone to which it is attached
    • muscles are innervated or supplied by a single nerve which can be excitatory (efferent) or sensory (afferent)
    • a motor unit consists of one efferent nerve fiber and the muscle fibers to which it attaches. every muscle fiber will be innervated. muscles have sensory components that provide info to the CNS concerning the state of the muscle
  96. Body systems
    a functionally defined group of organs
  97. Types of body systems
    • muscular- smooth striated and cardiac
    • skeletal- bones and cartilage
    • respiratory- passageways and tissues in gas exchange
    • digestive- oral cavity and pharynx, esophagus, liver, intestines, etc
    • reproductive- reproduction organs
    • urinary- kidney, urethra, ureters and bladder
    • endocrine- -production and dissemination of hormones
    • nervous system- nerve tissue and structures of the CNS and PNS
  98. systems of speech
    • respiratory system-resp. pathway, lungs, trachea, etc
    • phonatory system- production of sound and components of resp. system. includes laryngeal structures through which phonation is achieved
    • articulatory system- structures used in shaping the oral cavity to alter the characteristics of the sounds of speech.
    • resonatory system- nasal cavity and soft palate and portions of the anatomically defined resp. and digestive systems. the portion through the vocal tract through which the acoutic product of vocal fold vibration resonates (usually the oral, pharyngeal, and nasal cavities combined, somtimes only referring to the nasal cavities and nasopharynx)
