Question

write the function of various parts of neuron

Answer 1

nervous tissue is made of elongated cells called neurons. The cell body of a nerve cell,or neuron,contains a nucleus and cytoplasm and is called the cyton. short,hairlike extensions arising from the cyton are called dendrons.These dendrons further branch into thin dendrites.The axon is a long , tail-like cylindrical process with fine branches at the end . The axon is covered by a sheath.
The dendrites of a neuron are in close contact with the branches of the axon of another neuron. bundles of nerve fibres form a nerve .
The spinal cord and brain are made of nervous tissue . Nerves run to and from these organs , connecting them to various parts of the body. some of these nerves receive stimuli from within the body or from the external world ,and carry these messages to the brain and spinal cord in the form of short bursts of electric current , or impulses. Other nerves carry messages from the brain and spinal cord to various parts of the body which act accordingly.
