The function of a neuron is to transmit information within the nervous system. Neural transmission occurs when a neuron is activated, or fired (sends out an electrical impulse). Activation (firing) of the neuron takes place when the neuron is stimulated by pressure, heat, light, or chemical information from other cells. pegasus sewing machine parts book pdf

"WebDifference between nerve impulse and flow of electricity (transmission and speed): Here, neither any substance nor any electrons or ions move along the nerve fibre. Here, electrons actually move along the wire. Nerve impulses travel at a speed of about 100 metres per second. Electricity is conducted at a speed of about 150,000 km per second.

WebThe Nerve Impulse [HD Animation] WebSolution. Axon or nerve fibre is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neuron's cell body. The function of the axon is to transmit information to different neurons, muscles, and glands. Axons are microscopic in diameter (typically about one micrometer (µm)).

WebTransmission of Nerve Impulses. Neurons transfer electrical impulses which are transmitted quite rapidly along the cell surface membrane of the neuron from one end to another. These electrical impulses do not involve the flow of electrons, unlike the normal electric current. These impulses, referred to as action potentials, take place through ... Web1 minute = 0.016 hours.
