MICROANATOMY

Detailed explanation-1: -A neuromuscular junction consists of one neuron and all the skeletal muscles it stimulates. All muscles have at least two attachments: the origin and the insertion. The effect of the neurotransmitter on the muscle cell membrane is to temporarily modify its permeability of ions such as Na+ and K+.

Detailed explanation-2: -The neuromuscular junction is essentially comprised of two different types of cells: skeletal muscle cells and a type of nerve cell called motor neurons. Motor neurons are covered with ion channels, which open in response to electrical signals from the brain.

Detailed explanation-3: -One neuron and all the skeletal muscles it stimulates is known as a? motor unit.

Detailed explanation-4: -The skeletal muscle neuromuscular junction (NMJ) is a highly organized synapse formed between a motor neuron (MN) axon and a muscle fiber. It is designed to transmit efferent signals from projecting MNs to muscle fibers in order to actuate fiber contraction.
