Neuron Anatomy Definition

A neuron receives electrical input signals from sensory cells called sensory neurons and from other neurons. The central cell body is the process part of a neuron and contains the neurons nucleus associated cytoplasm organelles and other cell structures.

Alternatively a neuron may release neurohormones into the bloodstream.

Neuron anatomy definition. A typical neuron has a cell body containing a nucleus and two or more long fibres. Neurons function in the initiation and conduction of impulses. A nerve cell that receives and sends electrical signals over long distances within the body.

The neuron sends electrical output signals to muscle neurons called motoneurons or motor neurons and to other neurons. 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. The cell body produces proteins needed for the construction of other parts of the neuron.

Impulses are carried along one or more of these fibres called dendrites to the cell body. It is the main component of nervous tissue. In higher nervous systems only one fibre the axon carries the impulse away from the cell body.

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

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. Bundles of fibres from neurons are held together by connective tissue.
