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

    thoracic wall The thoracic wall (or chest wall) is the boundary of the thoracic cavity. The bony portion is known as the thoracic cage. However, the wall also includes muscle, skin, and fascia [Wikipedia: http://en.wikipedia.org/wiki/Thoracic_wall].
    atrium In the heart, the atrium is an upper chamber found on both sides of the heart. The left atrium receives red, oxygenated blood from the lungs by way of the pulmonary veins. The right atrium receives dark red blood from the other parts of the body [Brenda].
    ventricle In the heart, a ventricle is one of two large chambers that collect and expel blood received from an atrium towards the peripheral beds within the body and lungs [Wikipedia: http://en.wikipedia.org/wiki/Ventricle_(heart)].
    endocardium A thin serous membrane lining the cavities of the heart [Brenda].
    myocardium The middle and thickest layer of the heart wall, composed of cardiac muscle [Brenda].
    pericardium 1: The conical sac of serous membrane that encloses the heart and the roots of the great blood vessels of vertebrates.n2: A cavity or space that contains the heart of an invertebrate and in arthropods is a part of the hemocoel [Brenda].
    cardiac valve A heart valve normally allows blood flow in only one direction through the heart. The four valves commonly represented in a mammalian heart determine the pathway of blood flow through the heart. A heart valve opens or closes incumbent upon differential blood pressure on each side [Wikipedia: http://en.wikipedia.org/wiki/Heart_valve].
    cardiac conducting system The electrical conduction system that controls the heart rate. This system generates electrical impulses and conducts them throughout the muscle of the heart, stimulating the heart to contract and pump blood [MedTerms: http://www.medterms.com/script/main/art.asp?articlekey=8407].
    aorta The great arterial trunk that carries blood from the heart to be distributed by branch arteries through the body [Brenda].
    arterial intima The arterial intima incldues the endothelium, interla elastic lamina, and all intervening tissues [Stehbens, 1995: http://www.deepdyve.com/lp/elsevier/definition-of-the-arterial-intima-LB2GoUv3it].
    arterial media The middle coat of blood vessel walls, composed principally of thin, cylindrical, smooth muscle cells and elastic tissue. It accounts for the bulk of the wall of most arteries. The smooth muscle cells are arranged in circular layers around the vessel, and the thickness of the coat varies with the size of the vessel [MeSH: http://www.nlm.nih.gov/cgi/mesh/2012/MB_cgi?mode=&term=+L+o+w+e+r+ +l+i+m+b+&field=entry].
    arterial adventitia Adventitia is the outermost connective tissue covering of any organ, vessel, or other structure. It is also called the tunica adventitia or the tunica externa [Wikipedia: http://en.wikipedia.org/wiki/Adventitia].
    carotid artery A key artery located in the front of the neck that carries blood from the heart to the brain. Cholesterol plaques on the inner wall of the carotid artery can lead to stroke [Brenda].
    coronary artery Either of two arteries that arise one from the left and one from the right side of the aorta immediately above the semilunar valves and supply the tissues of the heart itself [Brenda].
    venous intima The innermost coat of blood vessels, consisting of a thin lining of endothelial cells longitudinally oriented and continuous with the endothelium of capillaries on the one hand and the endocardium of the heart on the other [Medical Dictionary: http://www.medical-dictionary.cc/what-does/venous-intima-mean].
    venous media The middle coat of blood vessel walls, composed principally of thin, cylindrical, smooth muscle cells and elastic tissue. It accounts for the bulk of the wall of most arteries. The smooth muscle cells are arranged in circular layers around the vessel, and the thickness of the coat varies with the size of the vessel [[MeSH: http://www.nlm.nih.gov/cgi/mesh/2012/MB_cgi?mode=&term=+L+o+w+e+r+ +l+i+m+b+&field=entry].
    venous adventitia The adventitia (tunica adventitia) is the outer coat of the vessel, and consists of connective tissue, nerves and vessel capillaries (vasa vasorum). It links the vessels to the surrounding tissues [Gray's Anatomy].
    alveolus A tiny, thin-walled, capillary-rich sac in the lungs where the exchange of oxygen and carbon dioxide takes place [Brenda].
    hematopoietic stem cells Hematopoietic stem cells (HSCs), also spelled hæmatopoietic stem cells, are multipotent stem cells that give rise to all the blood cell types from the myeloid (monocytes and macrophages, neutrophils, basophils, eosinophils, erythrocytes, megakaryocytes/platelets, dendritic cells), and lymphoid lineages (T-cells, B-cells, NK-cells). The definition of haematopoietic stem cells has undergone considerable revision in the last two decades. The hematopoietic tissue contains cells with long-term and short-term regeneration capacities and committed multipotent, oligopotent, and unipotent progenitors. HSCs constitute 1:10.000 of cells in myeloid tissue [Wikipedia: http://en.wikipedia.org/wiki/Hematopoietic_stem_cell].
    mesenchymal stem cell A special adult stem cell, which is a multipotent stem cell, that can be found in bone marrow and can produce all cell types of bone, cartilage, fat, blood, and connective tissues [Brenda].
    myeloid progenitor cell One of the two stem cells derived from hematopoietic stem cells, the other being the lymphoid progenitor cell. Derived from these myeloid progenitor cells are the erythroid progenitor cells and the myeloid cells [Brenda].
    T cells T cells or T lymphocytes belong to a group of white blood cells known as lymphocytes, and play a central role in cell-mediated immunity. They can be distinguished from other lymphocytes, such as B cells and natural killer cells (NK cells), by the presence of a T cell receptor (TCR) on the cell surface. They are called T cells because they mature in the thymus, and thus, can also be called thymocytes. There are several subsets of T cells, each with a distinct function [Wikipedia: http://en.wikipedia.org/wiki/T_cell].
    germinal center The area in the center of a lymph node containing aggregations of actively proliferating lymphocytes [Brenda].
    lingual tonsil The lingual tonsils are rounded masses of lymphatic tissue that cover the posterior region of the tongue [Wikipedia: http://en.wikipedia.org/wiki/Lingual_tonsils].
    pharyngeal tonsil Adenoids (or pharyngeal tonsil, or nasopharyngeal tonsil) are a mass of lymphoid tissue situated posterior to the nasal cavity, in the roof of the nasopharynx, where the nose blends into the throat [Wikipedia: http://en.wikipedia.org/wiki/Pharyngeal_tonsil].
