The neuromuscular junction is the region where motor neuron axon branches come in contact with the muscle fiber. The acetylcholine molecule, a neurotransmitter that is released from synaptic vesicle and that diffuse across the cleft. The synaptic cleft is the area between the presynaptic terminal and muscle fiber. This induces motor-end-plate to open when it gets bound to a ligand-gated sodium ion channel.

A motor unit associated with the stimulation of skeletal muscle is designated as a 1:8 motor unit. Which of the following statements is correct? The motor unit consists of one somatic neuron and 8 myofibers (muscle fibers) Each of the myofibers in the motor unit is innervated by more than one neuron It is part of the autonomic nervous system The neuron in the motor unit is an afferent neuron

hen an action potential arrives at the nerve terminal of a neuromuscular junction, which of the following statements best describes the events that occur? Depolarisation of the nerve terminal causes the release of ACh which activates nicotinic receptors on the skeletal muscle membrane to cause Ca2+ entry and muscle contraction. Depolarisation of the nerve terminal opens voltage-gated Ca2+ channels, Ca2+ entry brings vesicles containing ACh to the membrane which form fusion pores causing the release of ACh which activates voltage-gated Na+ channels at the end-plate. Depolarisation of the nerve terminal opens voltage-gated Ca2+ channels, Ca2+ entry brings vesicles containing ACh to the membrane which form fusion pores causing the release of ACh which binds to muscarinic receptors at the end plate. Depolarisation of the nerve terminal opens voltage-gated Ca2+ channels, Ca2+ entry brings vesicles containing ACh to the membrane which form fusion pores…

When an action potential arrives at the neuromuscular junction, acetylcholine is released into the synaptic cleft and binds to receptors in the postsynaptic membrane. Which of the following represents the correct order of the next series of events? A. An action potential travels down the T tubules, depolarization spreads through the T tubules, Ca2+ is released from the sarcoplasmic reticulum, and myosin binds to actin. B. Ca2+ is released from the sarcoplasmic reticulum, an action potential travels down the T tubules, depolarization spreads through the T tubules, and myosin binds to actin. C. An action potential travels down the T tubules, depolarization spreads through the T tubules, Ca2+ is taken up by the sarcoplasmic reticulum, and myosin binds to actin. D. T tubules are depolarized, Ca2+ is released from the sarcoplasmic reticulum, an action potential is created in the muscle cell, and myosin bonds to actin. E. An action potential travels…
