Question

Discuss about the physiology of nerves and neuromuscular junctions

Answer 1

The neuromuscular junction (NMJ) is the site of communication between motor nerve axons and muscle fibres. ... The function of the NMJ is to transmit signals from the motor neuron to the skeletal muscle fibre quickly and reliably, to ensure precise control of skeletal muscle contraction and therefore voluntary movement.

Answer 2

A nerve is an enclosed, cable-like bundle of nerve fibres called axons, in the peripheral nervous system. A nerve provides a common pathway for the electrochemical nerve impulses called action potentials that are transmitted along each of the axons to peripheral organs or, in the case of sensory nerves, from the periphery back to the central nervous system. Each axon within the nerve is an extension of an individual neuron, along with other supportive cells such as Schwann cells that coat the axons in myelin. I HOPE IT HELPFUL FOR YOU.
