All muscle fibres controlled by this nerve are recruited together, and the grouping of a motor neuron plus its family of muscle fibres is said to comprise a ‘motor unit’. When transmitter is not being released, ... See musculo-skeletal system. See also autonomic nervous system; cardiac muscle; motor neurons;

Exogenously administered tachykinins (substance P, ... In conclusion, capsaicin evokes release of several tachykinins from both central and peripheral endings of primary afferent neurons. The peptides released from sensory nerves in the periphery may induce effects such as protein extravasation and smooth muscle contraction.
