| mucous connective tissue | A type of connective tissue little differentiated beyond the mesenchymal stage; its ground substance of glycoproteins is abundant and contains fine collagenous fibres and fibroblasts; in its most characteristic form, it appears in the umbilical cord as Wharton's jelly. Synonym: gelatinous tissue. (05 Mar 2000) |

| multilocular adipose tissue | A thermogenic type of adipose tissue containing a dark pigment, and arising during embryonic life in certain specific areas in many mammals, including man. It is prominent in the newborn of all species in which it occurs and remains a distinct and conspicuous tissue in the adults of certain species, especially those that hibernate. It is also called brown adipose tissue. (12 Dec 1998) |
| connective tissue | <pathology> Rather general term for mesodermally derived tissue that may be more or less specialised. Cartilage and bone are specialised connective tissue, as is blood, but the term is probably better reserved for the less specialised tissue that is rich in extracellular matrix (collagen, proteoglycan etc.) and that surrounds other more highly ordered tissues and organs. (18 Nov 1997) |
| connective tissue activating peptide III | Cytokine, produced from platelet basic protein, that acts as a growth factor. (18 Nov 1997) |
| connective tissue cell | Any of the cell's of varied form occurring in connective tissue. (05 Mar 2000) |
| connective tissue cells | The cellular elements of the fibrous and nonfibrous components of the various forms of connective tissue. (12 Dec 1998) |
| connective tissue disease | <rheumatology> A heterogeneous group of diseases characterised by abnormal structure or function of one or more of the elements of connective tissue, i.e., collagen, elastin, or the mucopolysaccharides. They include rheumatoid arthritis, systemic lupus erythematosus, rheumatic fever, scleroderma and others, that are sometimes referred to as rheumatic diseases. They do not solely affect connective tissues but they are autoimmune in origin. Rheumatic fever and rheumatoid arthritis were first proposed as such disease's, and other so-called collagen disease's have been added. (18 Jul 2002) |
| connective tissue group | <physiology> A collective name for mucous tissue, dentin, bone, cartilage, and ordinary connective tissue, all derived from the mesenchyme. (05 Mar 2000) |
| corrosion of tissue | This is the destruction of tissue by a substance (such as a strong acid or base) on direct contact. (09 Oct 1997) |
| corrosive of tissue | This describes any substance (such as a strong acid or base) which destroys tissues on direct contact. (09 Oct 1997) |
| myeloid tissue | Bone marrow consisting of the developmental and adult stages of erythrocytes, granulocytes, and megakaryocytes in a stroma of reticular cells and fibres, with sinusoidal vascular channels. (05 Mar 2000) |
| haemopoietic tissue | <haematology> A reticulated tissue which produces blood. An example of such a tissue is bone marrow. (09 Oct 1997) |
| Haller's vascular tissue | <anatomy> The outer portion of the choroid of the eye containing the largest blood vessels. Synonym: lamina vasculosa choroideae, Haller's vascular tissue, uvaeformis, vascular layer of choroid coat of eye, vascular layer. (05 Mar 2000) |
| hard tissue | Tissue that has become mineralised, tissue having a firm intercellular substance, e.g., cartilage and bone. (05 Mar 2000) |
| primary lymphoid tissue | <anatomy> Tissue that is particularly rich in lymphocytes (and accessory cells such as macrophages and reticular cells), particularly the lymph nodes, spleen, thymus, Peyer's patches, pharyngeal tonsils, adenoids and (in birds) the Bursa of Fabricius. Central lymphoid tissue: A term occasionally used as synonym for primary lymphoid tissue but should be avoided to prevent confusion between anatomical location, which is irrelevant and centrality in the system. Peripheral lymphoid tissue: Secondary lymphoid tissue, not necessarily located peripherally. Primary lymphoid tissue: Lymphoid tissues in which immune cells develop as opposed to the secondary or peripheral lymphoid tissues in which antigen independent or antigen dependent stages of maturation take place and in which responsive lymphocytes are found. Primary lymphoid tissues are foetal liver, adult bone marrow and thymus (and Bursa of Fabricius in birds). Secondary tissues are lymph nodes, spleen, tonsils and mucosa associated lymphoid tissue.
