The medial longitudinal fasciculus is the main central connection for the oculomotor nerve, trochlear nerve, and abducens nerve. It carries information about the direction that the eyes should move. Lesions of the medial longitudinal fasciculus can cause nystagmus and diplopia, which may be associated with multiple sclerosis, a neoplasm, or a ...
The intercuneiform joints are the joints (articulations among) the cuneiform bones. The term "cuneocuboid joint" is sometimes used to describe the joint between the cuboid and lateral cuneiform, but this term is not recognized by Terminologia Anatomica .
(through the medial longitudinal fasciculus) the contralateral oculomotor (CN III) nucleus (specifically the population of its neurons that innervate the contralateral medial rectus muscle). The pararaphal nucleus - one of distinct neuron population in the PPRF - projects to the flocculus of the cerebellum .
The trochlear nerve controls the superior oblique muscle to rotate the eye along its axis in the orbit medially, which is called intorsion, and is a component of focusing the eyes on an object close to the face. The oculomotor nerve controls all the other extraocular muscles, as well as a muscle of the upper eyelid.
The cuneonavicular joint is a joint (articulation) in the human foot. It is formed between the navicular bone and the three cuneiform bones . The navicular and cuneiform bones are connected by dorsal and plantar ligaments .
Lisfranc fracture, with an increased distance between the medial cuneiform and the second metatarsal. The Lisfranc ligament connects the medial cuneiform bone to the second metatarsal . [ 2 ] It is a complex of 3 ligaments: the dorsal Lisfranc ligament, the interosseous Lisfranc ligament, and the plantar Lisfranc ligament.
The frontal eye field is reported to be activated during the initiation of eye movements, such as voluntary saccades [5] and pursuit eye movements. [6] There is also evidence that it plays a role in purely sensory processing and that it belongs to a “fast brain” system through a superior colliculus – medial dorsal nucleus – FEF ...
The accommodation reflex refers to the swelling of the lens of the eye that occurs when one looks at a near object (for example: when reading, the lens adjusts to near vision). [1] The eye's blind spot is a result of the absence of photoreceptors in the area of the retina where the optic nerve leaves the eye. [1]
