21

layers of muscle?

epimysium: surrounds entire muscle
perimysium: surrounds muscle bundles (fascicles)
endomysium: surrounds muscle fiber

22

layers of nerve

epineurium: surrounds enitre nerve
perineurium: surrounds nerve bundles (fascicles)
endoneurium: surrounds nerve fibers

23

blood vessel layers

tunica adventita
tunica media
tunica interna

24

tunica adventitia is?

outermost layer of BV wall; anchors surrounding structures, has nerve fibers & lymphatic vessels & tiny BV (aka vasa vasorum)

25

tunica media is?

middle layer of BV
regulated by vasomotor fibers & can cause vasoconstriction & vasodilation

26

tunica interna is?

aka initima Innermost layer- has 2 layers: thin endotehlium & basement membrane
reduces friction as blood moves through the vessel
