Wat (wie) is nucleus nervi oculomotorii - definitie

NUCLEUS IN A BRAIN
Nucleus of the oculomotor nerve; Nucleus of oculomotor nerve; Oculomotor nuclei; Oculomotor nuclei complex; Nucleus nervi oculomotorii; Oculomotor complex

Oculomotor nucleus         
The fibers of the oculomotor nerve arise from a nucleus in the midbrain, which lies in the gray substance of the floor of the cerebral aqueduct and extends in front of the aqueduct for a short distance into the floor of the third ventricle. From this nucleus the fibers pass forward through the tegmentum, the red nucleus, and the medial part of the substantia nigra, forming a series of curves with a lateral convexity, and emerge from the oculomotor sulcus on the medial side of the cerebral peduncle.
Edinger–Westphal nucleus         
ONE OF TWO NUCLEI OF THE OCULOMOTOR NERVE
Edinger-Westfall nucleus; Nucleus of Edinger-Westphal; Edinger-westphal nucleus; Edinger westphal nucleus; E-W nucleus; Edinger-Westphal nucleus; Nuclei accessorii nervi oculomotorii; Edinger–Westphal nuclei; Edinger–Westphal nucleuses; Edinger-Westphal nuclei; Edinger-Westphal nucleuses
The Edinger–Westphal nucleus (accessory oculomotor nucleus, or visceral oculomotor nucleus) is one of two nuclei of the oculomotor nerve. It is located in the midbrain.
Mesencephalic nucleus of trigeminal nerve         
Mesencephalic trigeminal nucleus; Mesencephalic nucleus; Nucleus mesencephalicus nervi trigemini; Mesencephalic trigeminal tract; Mesencephalic nucleus of the trigeminal nerve; Nucleus mesencephalicus
The mesencephalic nucleus of trigeminal nerve is involved with reflex proprioception of the periodontium and of the muscles of mastication in the jaw that functions to prevent biting down hard enough to lose a tooth. To subserve this reflex protective function, mechanoreceptive nerves in the periodontal ligament sense tooth movement and project to the mesencephalic nucleus.

Oculomotor nucleus

The fibers of the oculomotor nerve arise from a nucleus in the midbrain, which lies in the gray substance of the floor of the cerebral aqueduct and extends in front of the aqueduct for a short distance into the floor of the third ventricle. From this nucleus the fibers pass forward through the tegmentum, the red nucleus, and the medial part of the substantia nigra, forming a series of curves with a lateral convexity, and emerge from the oculomotor sulcus on the medial side of the cerebral peduncle.

The nucleus of the oculomotor nerve does not consist of a continuous column of cells, but is broken up into a number of smaller nuclei, which are arranged in two groups, anterior and posterior. Those of the posterior group are six in number, five of which are symmetrical on the two sides of the middle line, while the sixth is centrally placed and is common to the nerves of both sides. The anterior group consists of two nuclei, an antero-medial and an antero-lateral.

The nucleus of the oculomotor nerve, considered from a physiological standpoint, can be subdivided into several smaller groups of cells, each group controlling a particular muscle.

A nearby nucleus, the Edinger-Westphal nucleus lies dorsal to the main oculomotor nucleus. It is responsible for the autonomic functions of the oculomotor nerve, including pupillary constriction and lens accommodation.
