A nerve impulse is the relaying of a coded signal from a nerve cell to an effector (a muscle cell, a gland cell or another nerve cell) in response to a stimulus.
The Neuron. The neuron, a nerve cell, is the functional unit of the nervous system that carries the impulse (the message) to the appropriate part of the nervous system or interprets the impulse and allows a response. There are three types of neurons and each has different functions.) motor neurons âcarry impulses from the brain and spinal cord to muscles or glands. The Response Mechanism. When a stimulus is received by a sensory neuron, the impulse (or message) is carried through fibrous extensions called dendrites to the cell body.
