NERVE IMPULSES The functions of neuron are irritability and conduction. Irritability is the response of an organism to the stimulus. Conduction is the transmission of nerve impulse through the neurons of sensory and motor nerves. The external stimuli are light, temperature, chemicals, electri

This can be because of the ion channels which are present on the membrane of the neurons. These ion channels are selectively permeable to different ions. Therefore, the neurons are excitable.
2019-07-10 · Nerve impulses, or action potentials, are electrochemical impulses that cause neurons to release electrical or chemical signals that initiate an action potential in another neuron. Nerve impulses are received at neuronal dendrites, passed through the cell body, and are carried along the axon to the terminal branches.

Key Terms. action potential: a short term change in the electrical potential that travels along a cell; depolarization: a decrease in the difference in voltage between the inside and outside of the neuron; hyperpolarize: to increase the polarity of something, especially the polarity across a biological membrane; node of Ranvier: a small constriction in the myelin sheath of axons 2017-11-06 The Nerve Impulse [HD Animation] About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features © 2021 Google LLC The form of the action electric-potential in nerve membranes in the nerve cell-membranes are first described, it is, in essence, a nerve impulse and can be formed by virtue of periodic and ruled changes of non-uniform distribution of the sodium and potassium ions in the inner and surface of nerve … The Nerve Impulse Seen from Outside In the diagrams, arrows show the direction of current flow.
The nerve impulse travels along a neuron or across a synapse (junction), between one neuron and another, or between a neuron and an effector, such as a muscle or gland. Transmission of Nerve Impulse: The nerve cells remain bathed in the extracellular fluid (ECF) or interstitial fluid containing a large amount of sodium chloride and bicarbonates. Nerve impulse can define as a signal driven by either electrical, chemical or mechanical stimulus onward the segment of an axon filament. It generates a change in potential gradient of voltage-gated channels across the membrane, resulted from ionic movement in and out of the axolemma.

ii. If you like, colour in the diagram as suggested below. Axon - purple; Myelin sheath - yellow; Cell body - blue; Dendrites - green; Muscle fibres – red; iii. Now indicate the direction that the nerve impulse travels. 2. There are three different kinds of neurone or nerve cell. Match each kind with its function.
