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.
After the impulse has traveled through the neuron, the action potential is over, and the cell membrane returns Understanding the Transmission of Nerve Impulses-For Dummies Page 2 of 4http://www.dummies.com/how-to/content/understanding-the-transmission-of-nerve-impuls... Nerve impulse. Definition. noun. (1) The movement of action potential along a nerve fiber in response to a stimulus (such as touch, pain, heat or cold). (2) The relaying of a coded signal that travels along a nerve cell membrane to an effector, such as muscle, gland or another nerve cell. Supplement. 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. It is the means by which a nerve cell communicates with another cell. Transmission of a nerve impulse: Resting potential and action potential. Like the gaps between the Schwann cells on an insulated axon, a gap called a synapse or synaptic cleft separates the axon of one neuron and the dendrites of the next neuron. Medical Definition of NERVE IMPULSE. : the progressive physicochemical change in the membrane of a nerve fiber that follows stimulation and serves to transmit a record of sensation from a receptor or an instruction to act to an effector—called also nervous impulse. begins as a small depolarization which is carried as a wave of depolarization across the membrane of the neuron, in the form of an action potential. NERVE IMPULSE: Communications are transmitted by the nervous system as nerve impulses.. No related posts. Transmission of a nerve impulse: Resting potential and action potential.
