Excerpt. Thetrochlear nerveis the fourth cranial nerve (CN IV) and one of the ocular motor nerves that controls eye movement. The trochlear nerve, while the smallest of the cranial nerves, has the longest intracranial course as it is the only nerve to have a dorsal exit from the brainstem....
Cranial nerves are responsible for functions that are very important for everyday life. These functions include the special senses of sight, smell, taste, and hearing; facial sensation and movement; eye movement; tongue, pharyngeal, and laryngeal movement; balance; and parasympathetic input to ...
2. Optic Nerve.This is a sensory nerve responsible for your sense of sight. Light hits receptors in the eye that creates a signal that travels through the optic nerve to the brain where the brain deciphers what you're looking at. 3. Oculomotor Nerve.This is a motor nerve that helps you...
Penetrating injuries to the face and especially to the orbit of the eye are the most frequent causes of cranial nerve injury, resulting in injury to the optic (II), oculomotor (III), and abducens (VI) nerves. Injury to the trochlear (IV) nerve is not reported frequently [27]. Zygomatic...
- responsible for eyeball and eyelid movement - motor Cranial nerve IV Trochlear nerve - moves the eyeballs - motor Cranial nerve V Trigeminal nerve - sensory: convey sensation of touch, pain, and temperature - motor: control the facial muscles involved in chewing ...
Abducens nerve Nervus abducens 1/2 Synonyms: Cranial nerve VI, CN VI , show more... The abducens nerve is a purely motor nerve, responsible for providing general somatic efferent (GSE)/ motor innervation to just one muscle, the lateral rectus muscle of the eye. The muscle arises from ...
Cranial nerves III, IV and V are motor nerves and are responsible for the movement of the human eye. CN III, better known as the oculomotor nerve, is perhaps the most important of the three. The oculomotor nerves originate in the oculomotor nucleus in the midbrain and separate into superior...
Identify the cranial nerves that control the eye, and vision? Which cranial nerve carries sensory signals from the greatest area of the face? Cranial Nerve: The optic cranial nerve is the sensory nerve that receives senses from the...
muscles of the eye vii facial facial nerve provides innervation of facial expression viii vestibulocochlear vestibulocochlear nerve responsible for the special senses related to vestibular (location and movement perception functions of the ear) and cochlear (auditory part of the ear) function ix glosso...
Ocular mobility is an important feature of the eyes that help individuals collect as much visual input as possible. Movement of the eyes is carried out by the six extraocular muscles. They allow the eyes to move in the two principal planes and also about the visual axis. The nerve sup...
