Neuron Definition Anatomy

Impulses are carried along one or more of these fibres called dendrites to the cell body. Neuron action potential neurons are the cells that make up our nervous system and theyre made up of three main parts.

Central Nervous System Wikipedia

Neurons function in the initiation and conduction of impulses.

Neuron definition anatomy. 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 typical neuron has a cell body containing a nucleus and two or more long fibres.

A neuron receives electrical input signals from sensory cells called sensory neurons and from other neurons. In higher nervous systems only one fibre the axon carries the impulse away from the cell body. The dendrites which are little branches off of the neuron that receive signals from other neurons the soma or cell body which has all of the neurons main organelles like the nucleus and the axon which is intermittently wrapped in fatty myelin.

Bundles of fibres from neurons are held together by connective tissue. It is the main component of nervous 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.

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

Alternatively a neuron may release neurohormones into the bloodstream.
