A neuron, also known as a nerve cell, detects stimuli in its environment, integrates the information and then decides whether or not to transmit a signal to the next cell. There are three varieties of neurons: sensory ne... More »

Connector neurons, or interneurons, are neural cells that form connections between neurons. They cannot be classified as sensory or motor neurons and simply act as a liaison between two neurons. More »

A presynaptic neuron is a nerve cell that releases chemical messengers called neurotransmitters into the synapse, which is a gap at the end of a neuron. The postsynaptic neuron is the nerve cell that then receives these ... More »

The basic unit of the nervous system is the neuron, or nerve cell. Neurons are distinguished from other cells by their ability to communicate with other neurons through synaptic transmission and form highly structured co... More »

The part of the neuron that normally receives stimuli is the dendrite. The dendrites, which are numerous short-branched extensions, come together at the cell body. The purpose of the dendrites is to receive and combine t... More »

Sensory nerve endings detect stimuli from the environment and send impulses toward the central nervous system in response to these stimuli. Efferent nerve endings carry impulses from the central nervous system to effecto... More »
