How a nerve impulse is generated
WebReceptors are biological transducers that convert energy from both external and internal environments into electrical impulses. They may be massed together to form a sense organ, such as the eye or ear, or they may be scattered, as are those of the skin and viscera. Receptors are connected to the central nervous system by afferent nerve fibres. … Web44 Likes, 1 Comments - TRIO World Academy (@trio_world_academy) on Instagram: "TWA students have taken an opportunity to learn about the Application of Mathematics in ...

The majority of animal movements, however, are the result of nerve impulses passing along a line of nerve cells. Between the sensory nerve and the …
WebNerve cells are also called neurons. They are adapted to carry electrical impulses from one place to another. They feature: an axon – a single nerve fibre that carries nerve impulses away from a ... Webaction potential, the brief (about one-thousandth of a second) reversal of electric polarization of the membrane of a nerve cell (neuron) or muscle cell. In the neuron an action potential produces the nerve impulse, and in the muscle cell it produces the contraction required for all movement. Sometimes called a propagated potential because …
