Packing material of the body, fill spaces between organs, cushion and stabilize specialized cells in many organs, and support epithelia
What are the types of Dense Connective Tissue?
Collagen fibers are parallel to each other, packed tightly and aligned with the forces applied to the tissue
Areolar(Loose connective tissue)?
Surrounds nerves, blood vessels.
a. Open framework
b. Viscous ground substance accounts for most of its volume and absorbs shock
c. Elastic fibers make it resilient, can distort after damage
d. Form the padding between skin and muscle, pinch test or muscle contacts does not change shape
e. Vascular, common injection site
Adipose(Loose connective tissue)?
Fat capsule around Kidney, pericardial and abdominopelvic cavities.
a. Provides padding, absorbs shock, acts as an insulator to slow down heat loss, and is fillers around structures b. White fat- pale, yellow white color c. Brown fat- highly vascularized and individual adipocytes contain numerous mitochondria d. Lipid breakdown, energy absorbed by the blood to increase temperature e. Losing weight, cells shrink but are not killed f. Mesenchymal cells are ones that increase production of fat cells
Reticular(Loose connective tissue)?
Spleen and liver, reticular fibers create a complex 3-dimensional stroma, which supports the parenchyma (functional cell)
Regular(Dense connective tissue)?Makes up tendons and ligements
collagen fibers are parallel to each other, packed tightly and aligned with the forces applied to the tissue Table 4.10
a. Tendon-attach skeletal muscle to bone
b. Ligaments-connect 1 bone to another or stabilize the position of internal organs
c. Aponeurosis: tendinous sheet that attaches a broad, flat muscle to another muscle or to several bones of the skeleton
d. Stabilizes the positions of tendons and ligaments
e. Associated with muscles of lower back and abdomen and with tendons and ligaments of the palms of the hand or soles of the feet
Irregular(Dense connective tissue)?
Gives skin its strength Table4.10
a. Form an interwoven meshwork in no consistent pattern
b. Gives skin its strength in many directions
c. Capsules: surrounds internal organs such as a liver, kidney, spleen, and encloses cavities of the joints
Elastic(Dense connective tissue)?
Stabilize vertebrae of spine
What are the Supporting Connective tissues?
Cartilage(semi solid matrix)
What cells make up Cartilage?
Chondrocytes- cartilage cells, only cells in the cartilage matrix, occupy small chambers called lacunae.
What cells make up bone?
Osteocytes- bone cells
What are the types of cartilage?
Hyaline cartilage Connections between ribs, sternum, elbow, and knee
Elastic cartilage External flap of the ear, epiglottis, auditory tube, and small cartilages in the larynx
Fibrocartilage between spinal vertebrae, between pubic bones of the pubis
