Neuron Internal

An internal neuron is a special type of neurons in the central nervous system that are connected to afferent neurons that transmit information from the sensory organs and to efferent (motor) neurons that transmit commands to peripheral muscles. The neurons of the inner layer are located in the diencephalon and perform a very important function - they control many life processes, coordinating their work in the body. These nerve cells do not contain large bodies, but actively function by stimulating the functioning of other neurons. Their formation is completed by the 6-8th week of intrauterine development and is finally determined at birth, but their functioning occurs throughout life. The speed of movement of nerve impulses is high (transmitted in approximately 0.4-0.5 seconds), which ensures coordination of the activities of internal organs. The axonal fibers of motor cells connect to muscle receptors (in which the energy of external stimulation is transformed into a nerve impulse) and cardiac myocytes. This explains the presence of neurons of the inner nucleus in the central nervous system of animals and humans of all classes (except fish and protozoa).

Neurons of the inner nucleus reflexively influence many functions of the body,
