To determine:
The cranial nerve that is present in the lacrimal glands and the salivary glands.
Introduction:
The cranial nerves are part of the peripheral nervous system. Cranial nerves originate from the inferior surface of the brain. There are 12 pairs of cranial nerves. They are numbered according to their positions.
To determine:
The cranial nerve that is present in the lateral rectus eye muscles.
Introduction:
There are 12 pairs of cranial nerves. These are olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus, accessory, and hypoglossal nerves.
To determine:
The cranial nerve that is present in the intrinsic and extrinsic tongue muscles.
Introduction:
The cranial nerves are composed of many axons. Some cranial nerves are composed of only motor axons, whereas other cranial nerves are composed of only sensory axons. Trigeminal cranial nerves are composed of both sensory and motor axons.
