What is the structure of a nerve cell?

Answer 1

The structural unit of a nervous system is the nerve cell or neuron.The message that travels along a neuron is called an impulse.Each neuron consist of a cell body called Cyton.The cell body contains the nucleus.Several short fibre like structures extend from the cell body called Dendronswhich further divide into Dendrites.It receives message from other neurons.A single long fibre called Axon extend from the other side of the cell body which carries message from the cell body of one neuron to another.The neurons do not actually touch each other but communicate via Synapse where the axon terminal of one neuron impringes the dendrites of another neuron. Synapse is a junction for communication between neurons.

Answer 2

The structure of the nreve cell is a complex system.

That system is a long line of nerves that carry messages around our body.

It looks like this.....

Answer 3

Neuron have following structures

Dendrites are treelike extensions at the beginning of a neuron that help increase the surface area of the cell body and are covered with synapses. These tiny protrusions receive information from other neurons and transmit electrical stimulation to the soma.

The soma is where the signals from the dendrites are joined and passed on. The soma and the nucleus do not play an active role in the transmission of the neural signal. Instead, these two structures serve to maintain the cell and keep the neuron functional.

The support structures of the cell include mitochondria, which provide energy for the cell, and the Golgi apparatus, which packages products created by the cell and secretes them outside the cell wall.

The axon hillock is located and the end of the soma and controls the firing of the neuron. If the total strength of the signal exceeds the threshold limit of the axon hillock, the structure will fire a signal down the axon.

The axon is the elongated fiber that extends from the cell body to the terminal endings and transmits the neural signal. The larger the axon, the faster it transmits information. Some axons are covered with a fatty substance called myelin that acts as an insulator. These myelinated axons transmit information much faster than other neurons

The terminal buttons are located at the end of the neuron and are responsible for sending the signal on to other neurons. At the end of the terminal button is a gap known as a synapse. Neurotransmitters are used to carry the signal across the synapse to other neurons.

Answer 4

There are 3 main parts of a neuron: the cell body of the neuron, called the soma, sets of branching inputs called dendrites, and a long wire-like output called the axon. The dendrites can sometimes have small bumps on them called dendritic spines (where synapses would form), and the axon is divided at its end into some number of terminal branches, each ending at axon boutons (buttons).

If the neuron's axon is long and myelinated, then there would be a series of small glial cells wrapped one after another along the axon, sort of like the sections of a tootsie roll.

Since a neuron is a cell, in general it also has the same structures as any cell (cell membrane, organelles, cytoskeleton, pores).

To get an idea of what a generalized neuron looks like, place 3 fingers of one hand on the elbow of your other arm, extending outward away from your elbow; those three fingers would represent the terminal branches with the tips of your fingers being the terminal boutons, while your arm leading to those three fingers would be the axon, the back and palm of your hand on that arm would represent the body of the cell, and the five fingers of your hand would be the starting branches of the dendrites, the inputs to the neuron (imagine each finger having multiple hair-like further branchings) .

Answer 5

A nerve cell, or neuron, consists of a cell body (soma), dendrites (receives signals), and an axon (transmits signals). The axon is often surrounded by a myelin sheath for insulation and faster signal transmission. Nerve cells also have synaptic terminals to communicate with other cells.

Answer 7

the structure of a nerve cell changes in every different state. they have a stem and then the nerve endings come off it, this is a electric shock shape. by jade dodson
