Question

What is the difference from general somatic afferent fibers and special somatic afferent fibers? Is it possible for a nerve to have more than 1 fiber classification? Which nerve classification is responsible for conducting sensory impulses to the brain from the receptors of hearing and sight?

Answer 1

Answer:

optic nerve : It is the second cranial nerve which plays a major role in the vision of the eye.

vestibulocochlear nerve: This is the 8th cranial nerve, which is responsible for the balance of the body and the hearing.

Afferent fibres are the one getting the Information from the body ( organs) and send it to the brain, And efferent fibres will send the information from the brain to the organs of the body.

special somatic afferent fibres: This fibres will get the information from the optic and vestibulocochlear nerve( The information of the vision and hearing) and send to the brain.

General somatic afferent fibres: We can see these types of fibres in the spinal nerves from the spinal cord. It will generally detect the whole body, like pain, temperature and sensation of any part  of the body and send the info to the brain.

Is that possible to have more than 1 fibre classification: yes

Some nerve will carry both sensory and motor, these nerves are called mixed nerve.

These type of nerve will have both fibres. For example ; vagus nerve, facial nerve.

Which nerve classification is responsible for conducting sensory impulses to the brain from the receptors of hearing and sight? Vestibulocochlear nerve.
