Final answer:
The Nervus Intermedius of Facial Nerve (VII) mainly carries out sensory functions related to taste and salivation. The twelve cranial nerves have specific roles such as controlling senses, eye movements, facial expressions, and head-neck movements. Some nerves also carry autonomic fibers for parasympathetic functions.
Step-by-step explanation:
The Nervus Intermedius of the Facial Nerve (VII) is responsible primarily for sensory functions, such as taste sensation from the anterior two-thirds of the tongue, and it also provides parasympathetic innervation to the lacrimal, sublingual, and submandibular glands, aiding in tear and saliva production. This nerve contains both sensory and motor fibers, involved in the complex actions of facial expressions, taste, and autonomic control of salivary glands. Naming the twelve cranial nerves and their functions, these nerves can be categorized into those responsible for special senses (olfactory, optic, and vestibulocochlear), those connected to the extraocular muscles (oculomotor, trochlear, and abducens), those related to the face, oral cavity, and pharynx (trigeminal, facial, glossopharyngeal, and vagus), and the nerves involved in the movement of the head and neck (spinal accessory and hypoglossal).
