WebMay 17, 2024 · Nervous tissue is composed of two types of cells: neurons and glia, as shown in Figure 11.3. 1. Neurons are the primary type of cell that most anyone associates with the nervous system. They are responsible for the computation and communication that the nervous system provides. They are electrically active and release chemical signals to … WebB. FUNCTIONAL CLASSIFICATION:Neurons are classified according to the direction in which the nerve impulse (action potential) is conveyed with respect to the CNS. Sensory or afferent neuron: Either contain sensory receptors at their distal ends (dendrites) or are located just after sensory receptors that are separate cells.

A neuron, neurone, or nerve cell is an electrically excitable cell that fires electric signals called action potentials. Neurons communicate with other cells via synapses - specialized connections that commonly use minute amounts of chemical neurotransmitters to pass the electric signal from the presynaptic neuron to the target cell through the synaptic gap.
