1spinal chord reaction
reflex
2central nervous system reflex
from brin; voluntary movement
3action potential sends
signals through motor neurons to motor end plate
4motorend plate releases
acetyleholine
5acetyleholine
sends action potential along transverse tubules
6action potential causes
sarcoplasmic recticulum
7sarcolemma releases
calcium ions
8calcium bonds to
troponin
9when calcium bonds to troponin it
raises tropomysin and activates the cross bridge
