WebNeurotransmitters. Neurotransmitters are your body’s chemical messengers. They carry messages from one nerve cell across a space to the next nerve, muscle or gland cell. These messages help you move your limbs, feel sensations, keep your heart beating, and take in and respond to all information your body receives from other internal parts of ... WebThey are adapted to carry electrical impulses from one place to another. A bundle of neurones is called a nerve. There are three main types of neurone: sensory, motor and relay.

Nerve impulse Definition & Meaning - Merriam-Webster

WebThe sodium-potassium pump sets the membrane potential of the neuron by keeping the concentrations of Na + and K + at constant disequilibrium. The sudden shift from a resting to an active state, when the neuron generates a nerve impulse, is caused by a sudden movement of ions across the membrane—specifically, a flux of Na + into the cell.
