Question
Chapter 29.4, Problem 1MC
Summary Introduction
To determine:
An antagonistic pair of muscles.
Concept introduction:
Muscles are tissues that are made up of proteins filaments which are actin and the myosin fibers. They are soft tissues and they are found in most of the animals. They possess the property of contraction and relaxation and in this way they bring about the movement in a body. They are joined or they are in connection with the bones in a joint.

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
