Document Summary

Connection between axon and muscle cell = neuromuscular junction. Belly of a muscle = eshy contractile portion. Head of muscle/origin = beginning of the muscle. Fixator muscles - these muscles immobilize a joint that is crossed by another muscle. The xation muscle contracts at the same time as the agonist - remember the antagonit relaxes. The xation muscle prevents one of the actions of the agonist. Sesamoid bones redirect the movement of a tendon. Bursa is a uid lled sac between a tendon and a bone - reduces friction.
