Explanation / Answer
Answer 1: Yes, optic and facial nerves are part of Central nervous system because optic nerve and the facial nerves are 2nd and 7th of 12 paired cranial nerves. Facial nerves emerge from the pons of the brainstem and optic nerve is technically part of central nervous system because at the time of embryonic development they are derived from an out-pouching of the optic stalks.
Answer 2: The nerves innervating your Biceps brachii is a part of Somatic nervous system because skeletal muscles are voluntary, hence controlled by Somatic nervous system.
Answer 3: The nerves innervating your gastrointestinal tract are a part of Autonomic Nervous System because intrinsic neurons of the enteric nervous system innervate the GI tract and enteric nervous system is the part of Autonomic Nervous System.
Answer 4: Afferent neurons are the neurons carry information up to the brain.
