Tissues

The human body as well as that of other animals (Species) is highly structured into organs and tissues which serve specific functions. Tissue is the organizational level intermediate between cells and organs system which compose the whole organism. All the tissues and cell types defined in an animal organism are hierarchical structured and shall be fully described. o

    middle lobe of the cerebellum
    central lateral thalamic nucleus central lateral nucleus of thalamus; central lateral thalamic nucleus; nucleus centralis lateralis of thalamus; nucleus centralis lateralis thalami; centrolateral thalamic nucleus
    nucleus emboliformis [Brenda].
    nucleus globosus [Brenda].
    nucleus fastigii [Brenda].
    subthalamic nucleus A biconvex mass of gray matter on the medial side of the junction of the internal capsule and the crus cerebri; its chief connections are with the globus pallidus [Brenda].
    olfactory bulb A bulbous anterior projection of the olfactory lobe that is the place of termination of the olfactory nerves and is especially well developed in lower vertebrates (as fishes) [Brenda].
    hippocampus A curved elongated ridge that extends over the floor of the descending horn of each lateral ventricle of the brain and consists of gray matter covered on the ventricular surface with white matter;nThe hippocampus is a part of the temporal lobe, which has a well established role in learning, memory and emotion [Brenda].
    cochlea A division of the bony labyrinth of the inner ear of higher vertebrates that is usually coiled like a snail shell and is the seat of the hearing organ [Brenda].
    parahippocampal gyrus A long convolution on the medial surface of the temporal lobe, forming the lower part of the fornicate gyrus, extending from behind the splenium corporis callosi forward along the dentate gyrus of the hippocampus from which it is demarcated by the hippocampal fissure. The anterior extreme of the gyrus curves back upon itself, forming the uncus, the major location of the olfactory cortex [Brenda].
    nucleus parasolitarius A neuronal group ventrolateral to the nucleus solitarius has been termed the nucleus parasolitarius [Gray's Anatomy].
    infundibular nucleus A nucleus of nerve cells in the posterior hypothalamic region, extending into the median eminence and almost entirely surrounding the base of the infundibulum [Brenda].
    anterior olfactory nucleus A portion of the forebrain of vertebrates. It is found behind the olfactory bulb and in front of the piriform cortex (laterally) and olfactory tubercle (medially) in a region often referred to as the olfactory peduncle or retrobulbar area. The peduncle contains the anterior olfactory nucleus (AON) as well as two other much smaller regions, the tenia tecta (or dorsal hippocampal rudiment) and the dorsal peduncular cortex [Brenda].
    supraoptic nucleus A sharply defined nucleus of nerve cells in the anterior hypothalamic region, immediately above the lateral part of the optic chiasm; many of its cells are neurosecretory in function, secreting vasopressin, which is carried to the neurohypophysis (posterior pituitary) by the fibers of the supraopticohypophysial tract; other cells are osmoreceptors, which respond to increased osmotic pressure to signal the release of vasopressin by the neurohypophysis [Brenda].
    olfactory tubercle A small area of gray matter behind the olfactory trigone that is noted for receiving dopaminergic neurons from the substantia nigra and the reticular formation which have been implicated in schizoaffective disorders [Brenda].
    nucleus intercalatus A small collection of nerve cells in the medulla oblongata lying lateral to the hypoglossal nucleus [Mondofacto: http://www.mondofacto.com/facts/dictionary?Staderini's+nucleus]. intercalated nucleus of medulla; nucleus staderini; staderini's nucleus; staderinis nucleus
    suprachiasmatic nucleus A small group of neurons situated immediately dorsal to the optic chiasma in the anterior hypothalamus [Brenda].
    supraspinal nucleus A transverse section across the lower medulla oblongata intersects the dorsal, lateral and ventral funiculi, which are continuous with their counterparts in the spinal cord. The ventral funiculi are separated from the central grey matter by corticospinal fibres, which cross in the pyramidal decussation to reach the contralateral lateral funiculi. The decussation displaces the central grey matter and central canal dorsally. Continuity between the ventral grey column and central grey matter, which is maintained throughout the spinal cord, is lost. The column subdivides into the supraspinal nucleus (continuous above with that of the hypoglossal nerve), which is the efferent source of the first cervical nerve, and the spinal nucleus of the accessory nerve, which provides some spinal accessory fibres and merges rostrally with the nucleus ambiguus [Gray's Anatomy].
    ventral thalamic nuclei An area in the thalamus in the ventrolateral nuclear group consisting of a number of nuclei [Neurp: http://neuro.imm.dtu.dk/services/jerne/brede/WOROI_244.html]. The most rostral of the subdivisions of the ventral nucleus, receiving projections from the globus pallidus and projecting to the premotor and frontal cortex [Biology-Online: http://www.biology-online.org/dictionary/Ventral_anterior_nucleus_of_thalamus]. nucleus ventralis; anterior thalami
    secondary olfactory cortex Brodmann's area 28; major gateway for neocortical input to the hippocampus; origin of the perforant pathway; a component of the medial temporal lobe memory system. (CSP) * The cytoarchitecturally well-defined area of multilaminate cerebral cortex on the medial aspect of the parahippocampal gyrus, immediately caudal to the olfactory cortex of the uncus. The entorhinal cortex is the origin of the major neural fiber system afferent to the hippocampus, the so-called PERFORANT PATHWAY (Stedman, 25th ed) (MSH) [NeuroLex: http://neurolex.org/wiki/Category:Secondary_olfactory_cortex]. secondary olfactory cortical area; area 28 of Brodmann; secondary olfactory areas
    paracentral thalamic nucleus Cell groups within the internal medullary lamina of the thalamus. They include a rostral division comprising the paracentral, central lateral, central dorsal, and central medial nuclei, and a caudal division composed of the centromedian and parafascicular nuclei. paracentral nucleus thalamus; paracentral thalamic nucleus; nucleus paracentral thalami; paracentral nucleus of thalamus; nucleus paracentral; nucleus centralis lateralis superiorcentral dorsal nucleus; central dorsal thalamic nucleus; central lateral nucleus; central lateral thalamic nucleuscentral medial nucleuscentral medial thalamic nucleus; centromedian nucleusventromedian thalamic nucleus; interlaminar nuclei of thalamus; intralaminar nuclear group; intralaminar thalamic nuclei; paracentral nucleus; parafascicular nucleus; parafascicular thalamic nucleus; reticulate nuclei of thalamus; rostral intralaminar nuclei
    corpus striatum Either of a pair of masses of nervous tissue within the brain that contain two large nuclei of gray matter separated by sheets of white matter [Brenda].
    frontal lobe Front part of the brain; involved in planning, organizing, problem solving, selective attention, personality and a variety of higher cognitive functions including behavior and emotions [Brenda].
    olivary nuclei In anatomy, the olivary bodies or simply olives (Latin oliva and olivae, singular and plural, respectively) are a pair of prominent oval structures in the medulla oblongata, the lower portion of the brainstem. They contain the olivary nuclei [Wikipedia: http://en.wikipedia.org/wiki/Olivary_body].
    insula In each hemisphere of the mammalian brain the insular cortex (often called insula, insulary cortex or insular lobe) is a portion of the cerebral cortex folded deep within the lateral sulcus between the temporal lobe and the frontal lobe. The cortical area overlying it towards the lateral surface of the brain is the operculum (meaning "lid"). The opercula are formed from parts of the enclosing frontal, temporal and parietal lobes. It is believed to be involved in consciousness. The insular cortex is divided into two parts: the larger anterior insula and the smaller posterior insula in which more than a dozen field areas have been identified. The insulae play a role in diverse functions usually linked to emotion or the regulation of the body's homeostasis. These functions include perception, motor control, self-awareness, cognitive functioning, and interpersonal experience. In relation to these it is involved in psychopathology [Wikipedia: http://en.wikipedia.org/wiki/Insular_cortex]. insular cortex
