Neuron Anatomy Definition

They transmit impulses to other neurons or cells by releasing neurotransmitters at synapses. A neuron consists of a cell body perikaryon and its processes an axon and one or more dendrites.

The cell body produces proteins needed for the construction of other parts of the neuron.

Neuron anatomy definition. The central cell body is the process part of a neuron and contains the neurons nucleus associated cytoplasm organelles and other cell structures. Neurons function in the initiation and conduction of impulses. A neuron receives electrical input signals from sensory cells called sensory neurons and from other neurons.

It is the main component of nervous tissue. A typical neuron has a cell body containing a nucleus and two or more long fibres. Alternatively a neuron may release neurohormones into the bloodstream.

A neuron also known as a neurone old british spelling or nerve cell is an electrically excitable cell that communicates with other cells via specialized connections called synapses. In higher nervous systems only one fibre the axon carries the impulse away from the cell body. The neuron sends electrical output signals to muscle neurons called motoneurons or motor neurons and to other neurons.

A nerve cell that receives and sends electrical signals over long distances within the body. Bundles of fibres from neurons are held together by connective tissue. Neuron definition a specialized impulse conducting cell that is the functional unit of the nervous system consisting of the cell body and its processes the axon and dendrites.

Neurons contain the same cellular components as other body cells. Impulses are carried along one or more of these fibres called dendrites to the cell body.
