    Columnar cell: are tall and column shape.
  6. What are Pseudostratified Coumnar Epithelium?
    Tissues which give a false impression that several cell layers are present, because the cell nuclei lie at different levels above the basement membrane.
  7. What are Glandular Epithelia?
    A gland consists of one or more cells that make and secrete (export) a particular product.
  8. What is an Endocrine Gland?
    Endocrine Gland secrete internally, their products are called hormones.
  9. What are Exocrine Glands?
    These glands secrete their products onto body surface or into body cavities. They produce mucous, sweat, oil, salivery glands, bile, and many more.

  27. Name the two types of bone textures.
    • Compact Bone is the external layer and
    • Spongy Bone is the interal layer
  28. Structure of a typical long bone:
    Diaphysis: the shaft, forming the long axis of the bone. It forms a collar of compact bone that surrounds the medullary cavity or marrow cavity. This cavity is cover with a layer called the endosteum. The endosteum produces osteoblast.

    Epiphyses: the bone ends.
  29. Name the membrances of the typical long bone.
    Periosteum: the outter member of the bone with two layers.

    The outer layer contains the blood vessels and lymphatic nerves

    The inter layer conatins the OSTEOGENIC layer, which secretes osteoblasts and osteoclasts.
  30. Bone development:
    Chondrocytes-mineral depositon-calcification-chondrocytes die from pericondrium differntialtion of osteoblast-osteoid-primarny ossification center
  31. Volkmann's Canal are...
    also called perforating canals, which lie at right angles to the long axis of the bone and connect the blood and nerves supply of the periosteum to those in the central canals and the medullary cavity.
  32. Haversian canal are...
    also known as the central canal, they run longitudinally through the bone.
  33. How does the body balance the need for calcium?
    The parathyroid releases parathyroid hormone (PTH) in response to low calcium, which increases osteoclast activity in the bones.

    Once a balance is reached, then calcitonin, is released by the thyroid gland inhibits PTH secretion.
  34. Classification of Bones
    • long
    • short
    • flat
    • irregular

    basis of their shape and their proportion of compact or spongy bone
  35. Name the functional classification of joints.
    • Synarthroses: immovable
    • Phyarthroses: slight movable
    • Diarthroses: freely movable
  36. Fibrous Joints are...
    mostly synarthroses and are either:

    • Sutures
    • Syndesmoses
    • Gomphoses

    No joint cavity is present
  37. Sutures mean...
    "seams" occur only between bones of the skull.
  38. Syndesmoses are
    connected exclusively by ligaments.
  39. Gomphoses are...
    a peg-in-socket fibrous joint. The only example is the articulation of a tooth with its bony alveolar socket.
  40. Cartilaginous Joints are...
    the articulating bones united by cartilage. Like fibrous joints, they lack a joint cavity are are not highly movable.
  41. Synchondroses Cartilaginous Joint are...
    a bar or plate of hyaline cartilage uniting the bones. The most common example are the epiphyseal plates in the long bones of children.
  42. Symphyses Cartilaginous Joint are...
    the articular surfaces of the bones are covered with articular (hyaline) cartilage, which in turn is fused to an intervening pad, or plate, of fibrocartilage, which is the main connecting material.

    i.e. the public bones and between the vertabra
  43. Synovial Joints are..
    (joint eggs) those in which the articulating bones are separated by a fluid-containing joint cavity and is diarthroses.
  44. Synovial joint distinguishing features are
    Articular cartilage: double layered covering the opposing bones surfaces

    Reinforcing ligaments
  45. Bursae is
    essentially bags of lubricant, they act as "ball berings" to reduce friction between adjeacent structures during joint activity. Usually found in synovial joints.
  46. What are the three types of Synovial joint movements?
    • Gliding
    • Angular
    • Rotation
  47. Gliding is
    movements from side to side or back and forth. This movement is found in the intercarpal/tarsal joints and also in sternocostal.
  48. Angular Movement: Flexion
    • is a bending movement, usually along the sagittal plane.
    • It decreases the angle of the joint and brings the articulating bones closer together.

    i.e. bending your head to your chest.
  49. Angular Movement: Extension
    is the reverse of flexion. It increases the angle of the joints and brings the articulating bones further apart.
  50. Angular Movement: Abduction
    (moving away) is movement of a limb away from the midline or median plane of the body, along the frontal plane.
  51. Angular Movement: Adduction
    (moving toward) is the opposite of abduction, so it is the movement of a limb towards the body midline.
  52. Angular Movement: Circumduction
    is moving a limb so that it describes a cone in space.
  53. Angular Movement: Rotation
    is turning of a bone around its own long axis.
  54. Angular Movement: Supination/Pronation
    "turning backwards"/"turning forward"
  55. Angular Movement: Dorisflexion & Plantar Flexion of the Foot.
    Lifting the foot to the shin is dorsiflexion

    pointing the toes down is plantar flexion
  56. Angular Movement: Elevation & Depression
    means lifing a body part superiorly.

    i.e. the shoulder shrug/chewing.
  57. Angular Movement: Opposition
    The saddle joint between metacarpal 1 and the trapeium allows this movement.

    i.e. when you touch your fingers with your thumb.
  58. Angular Movement: Inversion & Eversion
    a special movement of the foot. To inverse, the sole of the foot turns medially; eversion is the opposite.
  59. Angular Movement: Protaction & Retraction
    Nonangular anterior and posterior movement in a transverse plane. The mandible is protracted when you jut out your jaw and retracted when you bring it back.
  60. Synovial Joint: Plane Joints
    the articular surfaces are essentially flat, and they allow one short nonaxial gliding movements.
  61. Synovial Joint: Hinge Joints
    the cylindrical end of one bone conforms to a trough-shaped surface on another.

    i.e. the elbow or inter-phalangeal
  62. Syovial Joint: Pivot Joints
    the rounded end of one bone conforms to a "sleeve" or ring composed of bone (and possibly ligaments) of another.

    i.e. the proximal radioulnar joint, where the head of the radius rotates within a ringlike ligament secured to the ulna.
  63. Synovial Joint: Condyloid Joints
    the oval articular surface of one bone fits into a complementary depression in another. This permits all angular motions.

    i.e. the radiocarpal (wrist) & metacarpophalangeal (knuckle)
  64. Syovial Joint: Saddle Joints
    resemble condyloid joints, but they allow greater freedom of movement. Each articular surface has both concave and convex areas (a saddle).

    i.e. the thumb (carpometacarpal joints of the pollex).
  65. Synovial Joint: Ball and Socket Joints
    the spherical or hemispherical head of one boen articulates with the cuplike socket of another. Universal movement.

    i.e. the shoulder and hip joints are the only examples.
