NURSING 3PA2 Study Guide - Final Guide: Hyaline Cartilage, Bone, Bone Marrow
Document Summary
Provides structure and strength to tissue/ organs in the body. Coagulation: different types of cartilage elastic, fibro, hyaline. Elastic more elastic fibers than collagen in its matrix. Fibrocartilage toughest of the 3, contains more collagen. Hyaline: ends of joints, located in the trachea (the windpipe, cartilage rings) *holes --- holes are created by bone tissue, porous tissue. Ex"s, ribs, scapula (shoulder blades), clavicle, sternum, cranium. Articultar cartilage is found at the ends of bones. Hormones responsible for bone growth - calcitonin (anterior pituitary gland), estrogen (from ovaries), testosterone (testes), growth hormone (pituitary gland) Bone formation the process of building up bone (putting in calcium*) Bone resorption/ reabsorption the process of breaking down bone (taking out calcium and putting it into the bloodstream*) (cardiac muscle cells will need calcium) Joint capsule ligaments (bone to bone), tendons (muscle to bone) Functions: secretes synovial fluid, can also store excess adipose tissue. Functions: helps supply functions to the joints, lubricates and moistens during movement.
