How is the muscular contraction stopped (i.e.: how does a muscle relax after contraction)? 1. The brain stops sending the nerve impulse that commands the muscle to contract, interrupting communication at the neuromuscular junction 2. Acetylcholineesterase (AChE) is released into the synaptic cleft to destroy any remaining Acetylcholine 3. No mechanism is necessary. When the antagonist begins to contract, it forces relaxation and stretch of the agonist muscle. 4. Relaxation occurs as the myosin heads are "snapped" off of the thick filaments. This interrupts the crossbridge and allows for muscles to stretch 5. Relaxation only occurs if the brain sends a "stop" signal to the muscle
Match each item in column A with the most closely related item in column B. Place letters for answers in the spaces provided.
Neuromuscular Junction: -Activation of nicotinic ACh receptors in the motor end plate results in both Na+ influx into and K+ efflux from the muscle fiber - An action potential in a motor neuron always produces a graded depolarization in the motor endplate and an action potential in the sarcolemma. -Acetylcholine released from the motor presynaptic terminal binds to voltage-gated ACh receptors in the motor endplate. -all of the above -a and b are right
Succinylcholine act as adepolarising agent that prevents repolarization of the somatic motor neuron. Thus, no further ACh is released until drug is cleared. Name another site within the MNJ we could target to prevent muscle contraction, and explain why this would work.
