adenoid tissue  lymphoid t.

adipose tissue  connective tissue made of fat cells in meshwork of areolar tissue.

areolar tissue  connective tissue made up largely of interlacing fibers.

bony tissue  bone.

brown 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 humans; it is prominent in the newborn.

cancellous tissue  the spongy tissue of bone.

cartilaginous tissue  the substance of cartilage.

chromaffin tissue  a tissue composed largely of chromaffin cells, well supplied with nerves and vessels; it occurs in the adrenal medulla and also forms the paraganglia of the body.

cicatricial tissue  the dense fibrous tissue forming a cicatrix, derived directly from granulation tissue.

connective tissue  the stromatous or nonparenchymatous tissues of the body; that which binds together and is the ground substance of the various parts and organs of the body.

elastic tissue , elastic tissue, yellow connective tissue made up of yellow elastic fibers, frequently massed into sheets.

endothelial tissue  endothelium.

epithelial tissue  epithelium.

erectile tissue  spongy tissue that expands and becomes hard when filled with blood.

extracellular tissue  the total of tissues and body fluids outside the cells.

fatty tissue  adipose t.

fibrous tissue  the common connective tissue of the body, composed of yellow or white parallel fibers.

gelatinous tissue  mucous t.

glandular tissue  an aggregation of epithelial cells that elaborate secretions.

granulation tissue  the newly formed vascular tissue normally produced in healing of wounds of soft tissue, ultimately forming the cicatrix.

gut-associated lymphoid tissue  (GALT) lymphoid tissue associated with the gut, including the tonsils, Peyer's patches, lamina propria of the gastrointestinal tract, and appendix.

indifferent tissue  undifferentiated embryonic tissue.

interstitial tissue  connective tissue between the cellular elements of a structure.

lymphadenoid tissue  tissue resembling that of lymph nodes, found in the spleen, bone marrow, tonsils, and other organs.

lymphoid tissue  a latticework of reticular tissue, the interspaces of which contain lymphocytes.

mesenchymal tissue  mesenchyme.

mucous tissue  a jellylike connective tissue, as occurs in the umbilical cord.

muscle tissue , muscular tissue the substance of muscle, consisting of muscle fibers, muscle cells, connective tissue, and extracellular material.

myeloid tissue  red bone marrow.

nerve tissue , nervous tissue the specialized tissue making up the central and peripheral nervous systems, consisting of neurons with their processes, other specialized or supporting cells, and extracellular material.

osseous tissue  the specialized tissue forming the bones.

reticular tissue , reticulated tissue connective tissue consisting of reticular cells and fibers.

scar tissue  cicatricial t.

sclerous tissues  the cartilaginous, fibrous, and osseous tissue.

skeletal tissue  the bony, ligamentous, fibrous, and cartilaginous tissue forming the skeleton and its attachments.

subcutaneous tissue  the layer of loose connective tissue directly under the skin.

white adipose tissue , yellow adipose tissue the adipose tissue comprising the bulk of the body fat.

interstitial tissue

Etymology: L, interstitium, space between; OFr, tissu

the connective and supporting tissue within and surrounding major functional elements of an organ.

interstitial

pertaining to or situated between parts or in the interspaces of a tissue.

atypical interstitial pneumonia

see atypical interstitial pneumonia.

interstitial cell adenoma

see interstitial cell tumor (below).

interstitial cell-stimulating hormone

luteinizing hormone.

interstitial cell

the cells of the connective tissue of the ovary or the testis (Leydig's cells), which furnish the internal secretion of those structures.

interstitial cell tumor

a common testicular tumor in old dogs. Most are benign and not associated with any major clinical disturbances but there may be concurrent perianal gland neoplasms, infertility and rarely feminization or viciousness. Called also Leydig cell tumor or interstitial cell adenoma.

interstitial edema

edema of the interstitial interlobular tissue in the lung.

interstitial emphysema

pulmonary emphysema with air accumulated in the interlobular connective tissue; characteristic of emphysema in cattle.

interstitial fluid

the extracellular fluid bathing cells in most tissues, excluding the fluid within the lymph and blood vessels.

interstitial gland

of the ovary, consisting of polyhedral epithelioid cells in the stroma of the ovary and have characteristics of cells which produce steroids.

interstitial nephritis

see nephritis.

interstitial fluid pressure

pressure exerted by the free interstitial fluid; if the pressure is negative this tends to suck fluid out of the vascular system and into the tissue space; if the pressure is greater than the intravascular pressure fluid tends to move out of the tissue space.

interstitial pneumonia

see pneumonia.

interstitial space

tissue space.

interstitial tissue

connective tissue between the cellular elements of a structure.
