Document Summary
Anatomy and physiology online lecture 5: skeletal tissue. Forming the framework of the body muscles, nerves, tissues hang off skin. Shape alignment and positioning of body parts. Bony boxes to protect more delicate tissue (skull, ribcage, vertebrae) Allow muscles to pull them so body can move, bones and joints make levers. Blood cell formation myelode tissue found in red bone marrow (in spongy bone) Articular cartilage found when one bone meets another bone, stops wear and tear, made up of hyaline cartilage covers articular surface of epiphyses. Compact bone outside of all bone, thicker, denser, heavier. Diaphysis middle part of bone , hollow, cylinder thick compact bone, provides strong support without heavy weight. Endosteum lining on inside of bone contains bone cells (makes new bons and destroys old bones) lines medullary in long bone (inside of compact bone) Epiphyseal line forms the location of where the bone stretches out and becomes longer, plate converts to line when you grow up.
