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

    hematological system The structures of the hematologic or hematopoietic system include the blood, blood vesels, and blood-forming organs (bone marrow, spleen, liver, lymph nodes, and thymus gland). The hematological system also plays an inportant role in hormone transport, the inflammotory and immune responses, temperature regulation, fluid-electrolyte balancem and acid-base balance [http://www.google.de/url?sa=t&rct=j&q=the%20structures%20of%20the%20hematologic%20or%20hematopoietic%20system%20include%20the%20blood%2C%20blood%20vesels%2C%20and%20blood-forming%20organs%20(bone%20marrow%2C%20spleen%2C%20liver%2C%20lymph%20nodes%2C%20and%20thymus%20gland).%20the%20hematological%20system%20also%20plays%20an%20inportant%20role%20in%20hormone%20transport%2C%20the%20inflammotory%20and%20immune%20responses%2C%20temperature%20regulation%2C%20fluid-electrolyte%20balancem%20and%20acid-base%20balance&source=web&cd=7&ved=0CF8QFjAG&url=http%3A%2F%2Fwww.reocities.com%2Fjtiongco_99_2000%2FMS%2Fms_lec5-1_hematologic_system.doc&ei=MdVQT9fNOsXV0QX_xfHrCw&usg=AFQjCNEUwaHxQc61N6EMZWYnMKlQ9IW8ug].
    nucleus of the spinal tract of the trigeminal The spinal trigeminal nucleus is a nucleus in the medulla that receives information about deep/crude touch, pain, and temperature from the ipsilateral face. The facial (cranial nerve 7), glossopharyngeal (CN9), and vagus nerves (CN10) also convey pain information from their areas to the spinal trigeminal nucleus.[1]. Thus the spinal trigeminal nucleus receives input from cranial nerves 5,7,9,10. This nucleus projects to the ventral posterior medial nucleus in the dorsal thalamus [Wikipedia: http://en.wikipedia.org/wiki/Spinal_trigeminal_nucleus]. spinal trigeminal nucleus

    spinal nucleus of the accessory nerve The spinal accessory nucleus lies within the cervical spinal cord (C1-C5) in the ventral horn. The nucleus ambiguus is classically said to provide the "cranial component" of the accessory nerve. However, the very existence of this cranial component has been recently questioned and seen as contributing exclusively to the vagus nerve. The terminology continues to be used in describing both human anatomy, and that of other animals [Wikipedia: http://en.wikipedia.org/wiki/Spinal_accessory_nucleus]. spinal accessory nucleus

    mammary gland The specialized accessory gland of the skin of female mammals that secretes milk. In the human female, it is a compound tubuloalveolar gland composed of 15 to 25 lobes arranged radially about the nipple and separated by connective and adipose tissue, each lobe having its own excretory (lactiferous) duct opening on the nipple. The lobes are subdivided into lobules, with the alveolar ducts and alveoli being the secretory portion of the gland [Brenda].
    nucleus of the tractus solitarius The solitary tract and nucleus are structures in the brainstem that carry and receive visceral sensation and taste from the facial (VII), glossopharyngeal (IX) and vagus (X) cranial nerves [Wikipedia: http://en.wikipedia.org/wiki/Solitary_nucleus]. solitary nucleus
    bone marrow The soft, fatty, vascular tissue that fills most bone cavities and is the source of red blood cells and many white blood cells [Brenda].
    peritoneum The smooth transparent serous membrane that lines the cavity of the abdomen of a mammal and is folded inward over the abdominal and pelvic viscera [Brenda].
    myometrium The smooth muscle coat of the uterus, which forms the main mass of the organ [Brenda].
    saccule The smaller of two membranous sacs in the vestibule of the inner ear [Brenda].
    globus pallidus The smaller and more medial part of the lentiform nucleus of the brain, separated from the putamen by the lateral medullary lamina. In official anatomic nomenclature, it is divided by the medial medullary lamina into two parts, lateral and medial, both of which have extensive connections with the corpus striatum, thalamus, and mesencephalon.nThe paleostriatum is the phylogenetically older part of the corpus striatum represented by the globus pallidus [Brenda].
    cerebrospinal fluid The serumlike fluid that circulates through the ventricles of the brain, the cavity of the spinal cord, and the subarachnoid space, functioning in shock absorption.nA liquid that is comparable to serum but contains less dissolved material, that is secreted from the blood into the lateral ventricles of the brain by the choroid plexus, circulates through the ventricles to the spaces between the meninges about the brain and spinal cord, and is resorbed into the blood through the subarachnoid sinuses, and that serves chiefly to maintain uniform pressure within the brain and spinal cord [Brenda].
    retina The sensory membrane that lines the eye, is composed of several layers including one containing the rods and cones, and functions as the immediate instrument of vision by receiving the image formed by the lens and converting it into chemical and nervous signals which reach the brain by way of the optic nerve [Brenda].
    dermis The sensitive vascular inner mesodermic layer of the skin [Brenda].
    jejunum The section of the small intestine that comprises the first two fifths beyond the duodenum and that is larger, thicker-walled, and more vascular and has more circular folds than the ileum [Brenda].
    salivatory nuclei The salivatory nuclei are the inferior salivatory nucleus and the superior salivatory nucleus [Wikipedia: http://en.wikipedia.org/wiki/Salivatory_nuclei].
    head The rostral part that usually comprises the brain, eyes, ears, nose and mouth (all of which aid with some sensory function) [Wikipedia: http://en.wikipedia.org/wiki/Head].
    renal vasculature The renal arteries normally arise off the side of the abdominal aorta, immediately below the superior mesenteric artery, and supply the kidneys with blood. Each is directed across the crus of the diaphragm, so as to form nearly a right angle with the aorta [Wikipedia: http://en.wikipedia.org/wiki/Renal_artery]. renal artery
    red nucleus The red nucleus is a structure in the rostral midbrain involved in motor coordination. It comprises a caudal magnocellular and a rostral parvocellular part [Wikipedia: http://en.wikipedia.org/wiki/Red_nucleus].
    membranous labyrinth The receptors for the senses of equilibrium and hearing are housed within a collection of fluid filled tubes and chambers known as the membranous labyrinth. The membranous labyrinth is lodged within the bony labyrinth and has the same general form; it is, however, considerably smaller and is partly separated from the bony walls by a quantity of fluid, the perilymph [Wikipedia: http://en.wikipedia.org/wiki/Membranous_labyrinth].
    putamen The putamen is a round structure located at the base of the forebrain (telencephalon). The putamen and caudate nucleus together form the dorsal striatum. It is also one of the structures that comprises the basal ganglia. Through various pathways, the putamen is connected to the substantia nigra and globus pallidus. The main function of the putamen is to regulate movements and influence various types of learning. It employs dopamine to perform its functions. The putamen also plays a role in degenerative neurological disorders, such as Parkinson's disease [Wikipedia: http://en.wikipedia.org/wiki/Putamen].
    renal proximal convoluted tubule The proximal tubule is the portion of the duct system of the nephron of the kidney which leads from Bowman's capsule to the loop of Henle [Wikipedia: http://en.wikipedia.org/wiki/Proximal_convoluted_tubule]. proximal convoluted tubule
    prostate The prostate (from Greek προστάτης - prostates, literally "one who stands before", "protector", "guardian") is a compound tubuloalveolar exocrine gland of the male reproductive system in most mammals [Wikipedia: http://en.wikipedia.org/wiki/Prostate].
    principal sensory The principal sensory nucleus (or chief sensory nucleus of V) is a group of second order neurons which have cell bodies in the dorsal Pons. It receives information about discriminative sensation and light touch of the face as well as conscious proprioception of the jaw via first order neurons of CN V. Most of the sensory information crosses the midline and travels to the contralateral ventral posteriomedial (VPM) of the thalamus via the Ventral trigeminothalamic tract. However, information of the oral cavity travels to the ipsilateral Ventral Posteriomedial (VPM) of the thalamus via the Dorsal trigeminothalamic tract [Wikipedia: http://en.wikipedia.org/wiki/Principal_sensory_nucleus_of_trigeminal_nerve]. principal sensory nucleus of trigeminal nerve
