Document Summary

Anatomical planes & axes = perpendicular to one another (90 degrees) **** 4 tissues of the body: epithelial, nervous, connective, muscle. In skin, glands, for sensory info (proprioception) Nervous tissue: regulates internal + external environments using neurons = electrical impulses of info. Connective tissue: made of collagen, elastin, and proteins different types of ct: loose, dense, fluid, supporting specialized ct: ligaments, tendons, fascia, cartilage. Skeletal muscle: striated (alternating light & dark striations), long, cylindrical, multinucleated (found at edges of fibers) Epimysium covers muscle belly: parallel= biceps brachii convergent= pectoralis, unipennate= fan out= extensor digitorum, bipennate = rectus femoris, multipennate= deltoid circular= orbicularis oris. Structure of a skeletal muscle cell/fibre (cell= fiber) *** muscle belly fascicle muscle fiber/cell myofibrils myofilaments ***** The volume of muscle cells decreases as we age= degeneration.
