![]() The part of the neuron that carries impulses away from the neuron cell body is the. ![]() The part of the neuron that carries impulses to the neuron cell body is the. The two types of cells found in the nervous system are. A relay neuron connects sensory and motor neurons and is found in the brain or spinal cord (see diagrams 14.1 and 14.2).ĭiagram 14. The two principal divisions that make up the nervous system are the. The three components of a neuron are a cell body or soma, one or more. A motor neuron is a nerve cell that transmits impulses from the brain or spinal cord to a muscle or gland. Neurons are the nerve cells that transmit impulses. A nerve is a bundle of axons.Ī sensory neuron is a nerve cell that transmits impulses from a sense receptor such as those in the eye or ear to the brain or spinal cord. The neuron carrying impulses from the spinal cord to the hind leg or tail of a horse, for example, can be several feet long. The cell body of neurons is usually located in the brain or spinal cord while the axon extends the whole distance to the organ that it supplies. This speeds up the rate at which the nerve impulses travel along the nerve (see diagram 14.1). ![]() ![]() Many axons have a sheath of fatty material called myelin surrounding them. A typical neuron has a cell body containing a nucleus, one or more branching filaments called dendrites which conduct nerve impulses towards the cell body and one long fibre, an axon, that carries the impulses away from it. Neurons are cells that have been adapted to carry nerve impulses.
