XI Spinal Accessory Nerve Controls muscles used in head movement.
XII Hypoglossal Nerve Controls muscles of tongue

Can cranial nerves be autonomic?

The cranial preganglionic neurons project to the cranial nerves with autonomic activity: III, VII, IX, and X. Unlike the sympathetic nervous system, the parasympathetic postganglionic neurons are located near to end-organ systems, resulting in long preganglionic axons and relatively short postganglionic axons.

What is the largest of the cranial nerves?

trigeminal nerve
The trigeminal nerve is the largest and most complex of the 12 cranial nerves (CNs). It supplies sensations to the face, mucous membranes, and other structures of the head. It is the motor nerve for the muscles of mastication and contains proprioceptive fibers.

Which cranial nerve is sensory?

Cranial nerves I, II, and VIII are pure sensory nerves. Cranial nerves III, IV, VI, XI, and XII are pure motor nerves. Cranial nerves V, VII, IX, and X are mixed sensory and motor nerves.

What is the longest cranial nerve?

The fourth cranial nerve (trochlear nerve) has the longest intracranial course; it is the only cranial nerve that has a dorsal exit from the brainstem (figure 1). It begins in the midbrain at the level of the inferior colliculus as fascicles extending from the fourth nerve nuclei.

What are the 3 types of cranial nerves?

There are three cranial nerves with primarily sensory function. Link to Sensory. Cranial nerve I, Olfactory, modulates smell, cranial nerve II, Optic,modulates vision. Cranial nerve VIII, Acoustovestibular, modulates hearing and balance.
