What is the sensory function of the oculomotor nerve?

The oculomotor nerve is the third cranial nerve (CN III). It allows movement of the eye muscles, constriction of the pupil, focusing the eyes and the position of the upper eyelid. Cranial nerve III works with other cranial nerves to control eye movements and support sensory functioning.

What is the sensory of oculomotor?

The oculomotor nerve conveys sensory information from selective muscles of the eye. The motor component controls pupil constriction and movement of some extrinsic eye muscles. Sensory fibers of this nerve supply proprioception information from muscles of the eyeball. …

Is the oculomotor nerve sensory or motor?

Nerves in Order Modality Function
Olfactory Special Sensory Smell
Optic Special Sensory Vision
Oculomotor Somatic Motor Visceral Motor Levator palpebrae, superioris, superior, medial & inferior recti muscles Parasympathetic to ciliary & pupillary constrictor muscles
Trochlear Somatic Motor Superior oblique muscle

What function is associated with the oculomotor nerve quizlet?

The oculomotor nerve helps control muscle movements of the eyes. The oculomotor nerve provides movement to most of the muscles that move the eyeball and upper eyelid, known as extraocular muscles.

How do you check oculomotor nerve function?

Step One: Open the right eyelid and shine the light into the right eye. Look only into the right eye to assess for a response. A normal response is a brisk constriction of the right pupil. If the pupil gets larger or has a sluggish response, it is considered abnormal.

What is a special sensory nerve?

Special sensory (special visceral afferent). Include special sensory neurons (e.g., smell, vision, taste, hearing, and equilibrium), mainly conducted by the olfactory, optic, and vestibulocochlear nerves (CNN I, II, and VIII, respectively) as well as by CN VII and CN X.

What are the parasympathetic functions of the oculomotor nerve quizlet?

– the parasympathetic function of the oculomotor nerve (III) is to Regulate the shape of the lens for vision and the diameter of the pupil.

What nerve connects the tongue to the brain?

Cranial Nerves

Number Name Function
X Vagus Nerve Sensory, motor and autonomic functions of viscera (glands, digestion, heart rate)
XI Spinal Accessory Nerve Controls muscles used in head movement.
XII Hypoglossal Nerve Controls muscles of tongue

What is the smallest nerve in the human body?

Trochlear nerve
Trochlear nerve is the smallest cranial nerve. Out of the 12 pairs of cranial nerves, the fourth paired cranial nerve, the trochlear nerve is the smallest of all by virtue of the number of axons.
