What does the nerve cell include?
The nerve cell can be thought of as just the nerve body, which is the main part of the nerve cell. The nerve cell is also known as a neuron. The entire neuron includes an axon, nerve body, dendrites, and axon terminals.
Do nerve impulses begin in the axon of a neuron?
No, nerve impulses do not begin in the axon of a neuron; they typically begin in the dendrites or the cell body. When a neuron receives sufficient stimulation, it generates an action potential that travels down the axon. The axon then conducts this impulse away from the cell body towards other neurons or target tissues.
What composed of a cell bodydendritesand axon?
Nerve cell or neuron
Difference between a neuron and a nerve?
A bundle of axons is a nerve. A neuron is the cell of the nervous system and is composed of dendrites, axon, and the cell body.
What is the nerve fiber that extends from a neuron and transmits electical impulses from that neuron to the dendrites of other neurons?
The axon
What is the route followed by nerve impulses when one neuron communicates with another?
When one neuron communicates with another, the nerve impulse travels down the axon of the presynaptic neuron, reaches the axon terminal, triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron's dendrites, initiating a new nerve impulse in the postsynaptic neuron.
How is a nerve specialised to carry out its function?
A nerve cell is called a neuron. The neuron has dendrites that receive impules from the previous neuron and send it to the cell body and an axon that transmits the impulse to the next neuron. There is a space between one cell's axon and the next cell's dendrites called a synapse. Neurotransmitters are released from the axon terminal to carry the impulse across the synapse.
Name the 3 main parts of a neuron?
The three main parts of a neuron are the dendrites, the axon, and the soma. The dendrites are the nerve endings, the axon is the body, and the soma is the cell body.
What is the long thin extension of the cell body of a neuron which is the conductor of nerve impulses?
An axon is the long extension of a nerve cell body. The dendrites are the short branches.
Difference between optic tract and optic nerve?
Bundles of neuron processes are called tracts in the cns and nerves in the pns
Extension of a neuron that sends impulses to other nerve cells or to muscles or glands?
axon
Which part of the neuron is responsible for generating a nerve impulse?
The axon is responsible for generating and transmitting a nerve impulse. It is a long, slender projection of the neuron that carries the electrical signal away from the cell body towards other neurons or muscles.
