Adipose Tissue definition: Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.
Adipose tissue definition: Dense irregular connective tissue, which predominantly consists of adipocytes.
adipose tissue definition: connective tissue composed of fat cells lodged in the meshes of areolar tissue.
Adipose tissue definition: Dense irregular connective tissue, which predominantly consists of adipocytes.
Adipose Tissue definition: A specialized form of connective tissue consisting primarily of adipocytes (fat cells), surrounded by a meshwork of collagen fibers.
Choristoma definition: A mass of histologically normal tissue present in an abnormal location.
Choristoma definition: Proliferation of normal tissue in an anatomic site in which this particular type of tissue is not normally present.
Connective Tissue definition: Tissue that supports and binds other tissues. It consists of CONNECTIVE TISSUE CELLS embedded in a large amount of EXTRACELLULAR MATRIX.
Connective tissue definition: Tissue which consists of fibroblasts, osteocytes or chondrocytes and intercellular matrix produced by these cells. Examples: bone (tissue), dense regular elastic tissue, areolar tissue, neuroglia, adipose tissue.
connective tissue definition: tissue that supports and binds other tissues; consists of connective tissue cells embedded in a large amount of extracellular matrix.
connective tissue definition: Supporting tissue that surrounds other tissues and organs. Specialized connective tissue includes bone, cartilage, blood, and fat.
Portion of connective tissue definition: Tissue which consists of fibroblasts, osteocytes or chondrocytes and intercellular matrix produced by these cells. Examples: bone (tissue), dense regular elastic tissue, areolar tissue, neuroglia, adipose tissue.
Connective Tissue definition: The supporting or framework tissue of the animal body, formed of fibrous and ground substance with more or less numerous cells of various kinds; it is derived from the mesenchyme, and this in turn from the mesoderm; the varieties of connective tissue are: areolar or loose; adipose; dense, regular or irregular, white fibrous; elastic; mucous; and lymphoid tissue; cartilage; and bone; the blood and lymph may be regarded as connective tissues the ground substance of which is a liquid.
Elastic Tissue definition: Connective tissue comprised chiefly of elastic fibers. Elastic fibers have two components: ELASTIN and MICROFIBRILS.
elastic tissue definition: form of connective tissue in which the elastic fibers predominate; it constitutes the ligamenta flava of the vertebrae and the ligamentum nuchae, especially of quadrupeds; it occurs also in the walls of the arteries and of the bronchial tree, and connects the cartilages of the larynx.
Emphysema definition: A pathological accumulation of air in tissues or organs.
Granulation Tissue definition: A vascular connective tissue formed on the surface of a healing wound, ulcer, or inflamed tissue. It consists of new capillaries and an infiltrate containing lymphoid cells, macrophages, and plasma cells.
Lymphoid Tissue definition: Specialized tissues that are components of the lymphatic system. They provide fixed locations within the body where a variety of LYMPHOCYTES can form, mature and multiply. The lymphoid tissues are connected by a network of LYMPHATIC VESSELS.
lymphatic tissue definition: specialized tissues that are components of the lymphatic system, providing fixed locations within the body where a variety of lymphocytes can form, mature, and multiply.
Lymphoid Tissue definition: Tissue characterized by the presence of large numbers of lymphocytes in different stages of transformation. Connective tissue cells including fibroblasts and macrophages may be present. Lymphoid tissue is framed by a network of reticular fibers and may be diffuse, or densely aggregated.
Membranes definition: Thin layers of tissue which cover parts of the body, separate adjacent cavities, or connect adjacent structures.
membrane definition: A very thin layer of tissue that covers a surface.
Membrane definition: A thin sheet or layer of pliable tissue, serving as a covering or envelope of a part, as the lining of a cavity, as a partition or septum, or to connect two structures.
Mucous Membrane definition: An EPITHELIUM with MUCUS-secreting cells, such as GOBLET CELLS. It forms the lining of many body cavities, such as the DIGESTIVE TRACT, the RESPIRATORY TRACT, and the reproductive tract. Mucosa, rich in blood and lymph vessels, comprises an inner epithelium, a middle layer (lamina propria) of loose CONNECTIVE TISSUE, and an outer layer (muscularis mucosae) of SMOOTH MUSCLE CELLS that separates the mucosa from submucosa.
mucosa definition: mucus-secreting membrane lining all body cavities or passages that communicate with the exterior.
mucous membrane definition: The moist tissue that lines some organs and body cavities (such as the nose, mouth, lungs) and makes mucus (a thick, slippery fluid).
MUCOSA definition: Mucous membrane. (NCI)
Mucosa definition: Mucous membrane.
Portion of neural tissue definition: Tissue which consists of neurons and their processes and neuroglia. Examples: Neural tissue of brain, neural tissue of peripheral ganglion, neural tissue of nerve.
Nerve Tissue definition: The tissue that generates and conducts electrical signals in the body. It contains the neurons.
Periapical Tissue definition: Tissue surrounding the apex of a tooth, including the apical portion of the periodontal membrane and alveolar bone.
tissue definition: collections of cells organized in a cooperative arrangement for the purpose of performing a particular function.
tissue definition: (TISH-oo) A group or layer of cells that are alike and that work together to perform a specific function.
Tissue definition: Organ part, which is uncountable and consists of similarly specialized cells and intercellular matrix, aggregated according to genetically determined spatial relationships; together with other tissues, it constitutes an organ component. Examples: epithelium, muscle (tissue), connective tissue, neural tissue, lymphoid tissue.
Tissues definition: Collections of differentiated CELLS, such as EPITHELIUM; CONNECTIVE TISSUE; MUSCLES; and NERVE TISSUE. Tissues are cooperatively arranged to form organs with specialized functions such as RESPIRATION; DIGESTION; REPRODUCTION; MOVEMENT; and others.
Portion of tissue definition: Anatomical structure which has as its parts cells of predominantly one type with or without intercellular matrix. Examples: epithelium, muscle tissue, connective tissue, neural tissue, lymphoid tissue.
TISSUE definition: An anatomical structure consisting of similarly specialized cells and intercellular matrix, aggregated according to genetically determined spatial relationships, performing a specific function. (NCI)
Tissue definition: An anatomical structure consisting of similarly specialized cells and intercellular matrix, aggregated according to genetically determined spatial relationships, performing a specific function.
Fetal Tissue definition: Any tissue from a fetus.
Subcutaneous Tissue definition: Loose connective tissue lying under the DERMIS, which binds SKIN loosely to subjacent tissues. It may contain a pad of ADIPOCYTES, which vary in number according to the area of the body and vary in size according to the nutritional state.
Bone tissue definition: Regular connective tissue, which consists of osteocytes and related cells, the intercellular matrix of which is ossified. Examples: woven bone, lamellar bone.
Bone (tissue) definition: Regular connective tissue, which consists of osteocytes and related cells, the intercellular matrix of which is ossified. Examples: woven bone, compact bone (tissue).
Bone Tissue definition: The mineralized osseous tissue that gives rigidity to the bones and forms its honeycomb-like three-dimensional internal structure.
Peripheral Primitive Neuroectodermal Tumor of Soft Tissues definition: A small round cell tumor with neural differentiation arising from the soft tissues.
pigment accumulation in tissues definition: The aggregation of coloring matter in a particular location in a tissue, occurring in response to an external stimulus. [GOC:jl]
Facial Tissues definition: Thin, soft, absorbent sheets of paper that are suitable for use on/around the face, e.g., the nose, eyes, mouth, etc. Facial tissues are typically supplied in multiple-use dispenser packs of prefolded tissues, with each tissue designed as a disposable sheet intended for single-use. They have a range of common applications, e.g., for capturing/absorbing mucus, sputum, tears, etc.
