MICROANATOMY

Detailed explanation-1: -The nerves that are responsible for innervating muscle fibers are called motoneurons. A single motoneuron and the muscle fibers it innervates are collectively called a motor unit.

Detailed explanation-2: -A motor neuron and all the myocytes (muscle cells) that it stimulates are called a motor unit, not a motor end plate. A motor end plate also called a neuromuscular junction, is a chemical synapse formed between the terminal branches of the motor neuron’s axon and a target muscle cell.

Detailed explanation-3: -Neurons carry messages from the brain via the spinal cord. The neurons that carry these messages to the muscles are called motor neurons.

Detailed explanation-4: -A motor unit is made up of a motor neuron and all of the skeletal muscle fibers innervated by the neuron’s axon terminals, including the neuromuscular junctions between the neuron and the fibres. Groups of motor units often work together as a motor pool to coordinate the contractions of a single muscle.

Detailed explanation-5: -A motor unit is defined as a single efferent neuron and all of the muscle fibers it controls. Each muscle contains multiple motor units.
