NEET PG DENTAL EXAM

Detailed explanation-1: -The neurons that carry these messages to the muscles are called motor neurons. Each motor neuron ending sits very close to a muscle fibre. Where they sit together is called a neuromuscular junction. The motor neurons release a chemical, which is picked up by the muscle fibre.

Detailed explanation-2: -A nerve cell conducts an electrochemical impulse be-cause of changes that take place in the cell membrane. These changes allow movement of ions through the mem-brane, setting up currents that flow through the mem-brane and along the cell. Similar impulses travel along muscle cells before they contract.
