chapter 9 part 1 Flashcards
smooth muscle
-involuntary
-pushes fluid through the digestive tract and the urinary tract (from kidney to bladder)
properties of muscle tissue
-excitablility
-contractibility
-extensibility
-elasticity
excitability
response to stimuli
extensibility
contract with resting
skeletal muscle
-voluntary
-causes movement by pulling tendons
-posture
-support
-regulation (pee and vomit)
-BODY TEMP
microscopic muscle anatomy
microfibrils, myofilaments, sacromeres
epimysium
tissue around entire muscle
-it is a connective tissue
perimysium
tissue dividing muscle into fascicles (fiber bundles)
fascicle
fiber bundle
endomyseum
tissue surrounding individual fiber
-has blood vessels that make coiled networks that are used for flexion and extension
tendons
connect muscle and bone
aponeuroses
connect muscle to muscle
motor end plate
neuromuscular junction
-where the nerve and muscle meet
sarcolemma
plasma membrane of muscle fiber (has nucleus!!!)
sarcoplasm
cytosol of muscle cell (where the myofibrils are!!!!!!)
