e. Cranial nerves are the nerves that emerge directly from the brain (including the brainstem ), of which there are conventionally considered twelve pairs. Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing.
Three Parts: V 1 ( ophthalmic nerve) is located in the superior orbital fissure V 2 ( maxillary nerve) is located in the foramen rotundum. V 3 ( mandibular nerve) is located in the foramen ovale . Receives sensation from the face, mouth and nasal cavity, and innervates the muscles of mastication . VI.
v. t. e. The abducens nerve or abducent nerve, also known as the sixth cranial nerve, cranial nerve VI, or simply CN VI, is a cranial nerve in humans and various other animals that controls the movement of the lateral rectus muscle, one of the extraocular muscles responsible for outward gaze. It is a somatic efferent nerve .
D009460. [ edit on Wikidata] A neurological examination is the assessment of sensory neuron and motor responses, especially reflexes, to determine whether the nervous system is impaired. This typically includes a physical examination and a review of the patient's medical history, [ 1] but not deeper investigation such as neuroimaging.
The trochlear nerve ( / ˈtrɒklɪər / ), [ 1] ( lit. pulley-like nerve) also known as the fourth cranial nerve, cranial nerve IV, or CN IV, is a cranial nerve that innervates a single muscle - the superior oblique muscle of the eye (which operates through the pulley -like trochlea ). Unlike most other cranial nerves, the trochlear nerve is ...
v. t. e. The vestibulocochlear nerve or auditory vestibular nerve, also known as the eighth cranial nerve, cranial nerve VIII, or simply CN VIII, is a cranial nerve that transmits sound and equilibrium (balance) information from the inner ear to the brain. Through olivocochlear fibers, it also transmits motor and modulatory information from the ...
Occipital neuralgia. Occipital neuralgia (ON) is a painful condition affecting the posterior head in the distributions of the greater occipital nerve (GON), lesser occipital nerve (LON), third occipital nerve (TON), or a combination of the three. It is paroxysmal, lasting from seconds to minutes, and often consists of lancinating pain that ...
Anatomical terms of neuroanatomy. [ edit on Wikidata] The ophthalmic nerve ( CN V1) is a sensory nerve of the head. It is one of three divisions of the trigeminal nerve (CN V), a cranial nerve. It has three major branches which provide sensory innervation to the eye, and the skin of the upper face and anterior scalp, as well as other structures ...
