Heya mate
A neuron, neurone (old British spelling) or nerve cell, is an electrically excitable cell[1] that communicates with other cells via specialized connections called synapses. It is the main component of nervous tissue in all animals except sponges and placozoa. Plants and fungi do not have nerve cells.
In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell.
The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord, which contains cerebrospinal fluid.
A brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is located in the head, usually close to the sensory organs for senses such as vision. It is the most complex organ in a vertebrate's body.
hope it may help u...
if so pls mark brainliest......
Answer:
Synapse - It is region of union of one axon of a neuron to another dentrite of another neuron and so on.
Neuron- It is a nerve cell which is found in animal body which helpful in responding to stimulus.Its length can upto 1 - 2m
3.Brain- It is a basic organ which helps in analytical reasoning of a person which helps it to do the work intelligently.
4.Spinal Cord- It is a bone marrow. which provides support to the whole body.It is very essential as nervous system also originates from here only
