Intercalated Nucleus

	Intercalated Nucleus Intercalated nucleus (''nucleus intercalatus'') called also Staderini nucleus is a group of nerve cells in the medulla oblongata, between the dorsal nucleus of the vagus nerve The dorsal nucleus of vagus nerve (or posterior nucleus of vagus nerve or dorsal vagal nucleus or nucleus dorsalis nervi vagi or nucleus posterior nervi vagi) is a cranial nerve nucleus for the vagus nerve in the medulla that lies ventral to the fl ... (lateral to the intercalated nucleus) and the nucleus of the hypoglossal nerve (medial to intercalated nucleus), forming part of the perihypoglossal nuclear complex. Function. Probably involved in the control of the vestibuloocular reflex and may contribute to the vertical neural integrator.

picture info	Medulla Oblongata The medulla oblongata or simply medulla is a long stem-like structure which makes up the lower part of the brainstem. It is anterior and partially inferior to the cerebellum. It is a cone-shaped neuronal mass responsible for autonomic (involuntary) functions, ranging from vomiting to sneezing. The medulla contains the cardiac, respiratory, vomiting and vasomotor centers, and therefore deals with the autonomic functions of breathing, heart rate and blood pressure as well as the sleep–wake cycle. During embryonic development, the medulla oblongata develops from the myelencephalon. The myelencephalon is a secondary vesicle which forms during the maturation of the rhombencephalon, also referred to as the hindbrain. The bulb is an archaic term for the medulla oblongata. In modern clinical usage, the word bulbar (as in bulbar palsy) is retained for terms that relate to the medulla oblongata, particularly in reference to medical conditions. The word bulbar can refer to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Dorsal Nucleus Of The Vagus Nerve The dorsal nucleus of vagus nerve (or posterior nucleus of vagus nerve or dorsal vagal nucleus or nucleus dorsalis nervi vagi or nucleus posterior nervi vagi) is a cranial nerve nucleus for the vagus nerve in the medulla that lies ventral to the floor of the fourth ventricle. It mostly serves parasympathetic vagal functions in the gastrointestinal tract, lungs, and other thoracic and abdominal vagal innervations. These functions include, among others, bronchoconstriction and gland secretion. The cell bodies for the preganglionic parasympathetic vagal neurons that innervate the heart reside in the nucleus ambiguus. Additional cell bodies are found in the nucleus ambiguus, which give rise to the branchial efferent motor fibers of the vagus nerve (CN X) terminating in the laryngeal, pharyngeal muscles, and musculus uvulae.

	Hypoglossal Nucleus The hypoglossal nucleus is a cranial nerve nucleus, found within the medulla. Being a motor nucleus, it is close to the midline. In the open medulla, it is visible as what is known as the ''hypoglossal trigone'', a raised area (medial to the vagal trigone) protruding slightly into the fourth ventricle. The hypoglossal nucleus is located between the dorsal motor nucleus of the vagus and the midline of the medulla. Axons from the hypoglossal nucleus pass anteriorly through the medulla forming the hypoglossal nerve which exits between the pyramid and olive in a groove called the anterolateral sulcus.

	Perihypoglossal Nuclear Complex {{one source, date=April 2012 Perihypoglossal nuclei (''nuclei perihypoglossales''), called also perihypoglossal complex or perihypoglossal nuclear complex or satellite nuclei is a group of neurons in the floor of the fourth ventricle, in close proximity to the nucleus of the hypoglossal nerve in the gray substance of the medulla oblongata, all of which contain cells with characteristics suggestive of reticular connections. The complex includes three nuclei: the intercalated nucleus, the nucleus prepositus, and the sublingual nucleus. The nucleus prepositus is the largest of the three. Perihypoglossal nuclei receive afferents from the cerebral cortex, vestibular nuclei, accessory oculomotor nuclei, and paramedian pontine reticular formation. Efferent fibers of these nuclei terminates in cranial nerve nuclei involved in extraocular movement (oculomotor, trochlear, abducens), the cerebellum The cerebellum (Latin for "little brain") is a major feature of the hindbra ...
