Muscular P.6
Names of all the skeletal muscles - only my list
triceps brachii
anticus
anconeus
brachialis
pronator teres
biceps brachii
flexor carpi
coracobrachialis
palmaris longus
radialis
Sarcomere
actin
myosin
tropomyosin
Z line
thick filaments
H zone
thin filaments
I band
A band
neuromuscular junction (7 steps)
ACH diffuses across the synaptic cleft and binds to it's receptors on the muscle
ACH binding opens ion channels and Sodium rushes into the muscles
Calcium causes the vesicles to release ACH into the synaptic cleft
If the muscle reaches the threshold at the motor end plate an AP occurs on the muscle
Electrical gated calcium channels open. and calcium enters the axon terminal
An AP travels down the axon. to the axon terminal.
ACH is broken down by acetylcholine esterase
sliding filament theory of muscle contraction (steps)
cross bridge forms
Myosin head slides
Calcium ions are released
skeletal muscle contraction occurres
troponin
Cross bridge breaks.
major functions of the muscular system
Protection
Support
Heat Generation
Movement
Blood circulation
3 types of muscles & their functions
Smooth muscle – located in internal structures including the digestive system, uterus and blood vessels such as arteries.
Skeletal muscle – the specialized tissue that is attached to bones and allows movement.
Cardiac muscle – the muscle specific to the heart.
Muscle coverings
epimysium
endomysium
perimysium
Action potential in a muscle fiber
a special type of electrical signal that can travel along a cell membrane as a wave.
