Define neuron. name the part of the neuron where
a) information is acquired
b) through which information travels as an electrical impulse
c) where the impulse must be converted into a chemical signal for onward transmission
please answer correctly guys...
Answers
Answer:
Neurons are the nervous tissues which are made up of an organised network of nerve cells, and are specially designed to transmit information to other nerve cells, muscle, or gland cells.
a) information is acquired through the dendrite.
b)axon is through which information travels as an electrical impulse.
c) nerve ending is where the impulse must be converted into a chemical signal for onward transmission.
Neuron:
The neuron is the basic functional and fundamental unit of the nervous system.
It is the longest cell in the human body.
The network of nerve cells makes nervous tissue.
Functions:-
- They used to detect the information from the outer surrounding.
- They used for conducting information through impulses from one part of the body to another.
Part of the neuron where
a) Information is acquired - Dendrites.
[Dendrites are 'protoplasmic', branched manner of the cell body. It receives and transmit stimulus]
b) Through which information travels as an electrical impulse - Axon.
[Axon is the fiber-like cytoplasmic process. It is long. They used to conduct impulse differently away from the cell body(Cyton - It is the rounded part of the neuron. It contains a central nucleus, abounding cytoplasm, and other cell organelles except for centrioles). Also, it has a protective covering -Myelin sheath.]
c) Where the impulse must be converted into a chemical signal for onward transmission - Nerve Ending. (cross gap - Synapse )
[They are branch-like terminations of neurons.]
Synapse - It is a tiny gap between two neighboring neurons, in which the nerve impulse moves from one neuron to the next neuron in one direction only.
