Chapter 11, Problem 2RQ
Summary Introduction
To determine:
The muscle which aids an agonist either by causing an alike movement or stabilizing a joint.
Introduction:
The muscles of the human body are classified into skeletal, cardiac and the smooth muscles. The muscle movements depend on the function as well as its location. The muscular movements play a vital role in locomotion as well as in the movement of food and liquid within the body.

Which of the following is/are correct? A) The brain stops sending the nerve impulse that commands the muscle to contract, interrupting communication at the neuromuscular junction B) Acetylcholineesterase (AChE) is released into the synaptic cleft to destroy any remaining Acetylcholine C) No mechanism is necessary. When the antagonist begins to contract, it forces relaxation and stretch of the agonist muscle. D) Relaxation occurs as the myosin heads are "snapped" off of the thick filaments. This interrupts the crossbridge and allows for muscles to stretch E) Relaxation only occurs if the brain sends a "stop" signal to the musclearrow_forward
