connective tissue [kō-nek´tiv]
a fibrous type of body tissue with varied functions; it supports and connects internal organs, forms bones and the walls of blood vessels, attaches muscles to bones, and replaces tissues of other types following injury. Connective tissue consists mainly of long fibers embedded in noncellular matter, the ground substance. The density of these fibers and the presence or absence of certain chemicals make some connective tissues soft and rubbery and others hard and rigid. Compared with most other kinds of tissue, connective tissue has few cells. The fibers contain a protein called collagen
. Connective tissue can develop in any part of the body, and the body uses this ability to help repair or replace damaged areas. Scar tissue is the most common form of this substitute. See also collagen diseases
the physical or functional supporting tissue of the animal body, a major constituent of which (in addition to various kinds of cells) is an extracellular matrix of ground substance, protein fibers, and structural glycoproteins; it is derived from the mesenchyme, which in turn is derived mainly from mesoderm; the many kinds of connective tissue may be classified according to cell-matrix proportion (loose vs. dense), arrangement of fibers (regular dense vs. irregular dense), fiber type (collagenous, elastic), embedded cell type (adipose, lymphoid, hemopoietic), degree of differentiation (mesenchymal, mucous), location (subcutaneous, periosteal, perichondrial), appearance (areolar, granulation), or nature of matrix (cartilaginous, osseous, or, in the cases of blood and lymph, liquid).
Tissue arising chiefly from the embryonic mesoderm that is characterized by a highly vascular matrix and includes collagenous, elastic, and reticular fibers, adipose tissue, cartilage, and bone. It forms the supporting and connecting structures of the body.
con·nec·tive tis·sue (kŏ-nek'tiv tish'ū)
The supporting or framework tissue of the animal body, formed of fibers 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; lymphoid tissue; cartilage; and bone. Blood and lymph may be regarded as connective tissues, the ground substance of which is a liquid.
Synonym(s): interstitial tissue
Tissue that supports and connects other tissues and parts of the body. Connective tissue has comparatively few cells. Its bulk consists of intercellular substance or matrix, whose nature gives each type of connective tissue its particular properties. The vascular supply varies: cartilage, none; fibrous, poor; adipose, good; and bone, abundant. Connective tissue includes the following types: areolar, adipose, fibrous, elastic, reticular, cartilage, and bone. Blood may also be considered a connective tissue. illustration
connective tissue Loose or dense collections of COLLAGEN fibres and many cells, in a liquid, gelatinous or solid medium. Connective tissue participates in the structure of organs or body tissue or binds them together. It includes cartilage, bone, tooth dentine and lymphoid tissue.
connective tissue an animal tissue in which the intercellular matrix forms the major part. Such tissues fall into three main groups:
- ‘true’ connective tissue (ADIPOSE TISSUE, AREOLAR TISSUE, yellow elastic tissue (LIGAMENTS) and white fibrous tissue (TENDONS);
- skeletal tissue: BONE and CARTILAGE;
- blood, the last differing from the others in containing no fibres in the matrix (BLOOD PLASMA).
Tissue that supports and binds other tissue; much of it occurs outside of cells (extra-cellular) and consists of fibrous webs of the polymers, elastin and collagen. Cutis laxa is associated with defects in these fibers.
con·nec·tive tis·sue (kŏ-nek'tiv tish'ū)
Physical or functional supporting tissue of the animal body, a major constituent of which (in addition to various kinds of cells) is an extracellular matrix of ground substance, protein fibers, and structural glycoproteins; derived from the mesenchyme, which in turn is derived mainly from mesoderm.
Patient discussion about connective tissue
Q. My neighbor's kid had a lens dislocation due to Marfan's disease. Is this a contagious thing? My neighbor's have a sweet 8 year old boy. he had a lens dislocation due to a connective tissue disease named Marfan (I think that the name).
It sounds like a very serious condition. My boy is playing with this kid several hour a week. should I take him to the GP to see that his is not infected with this marfan thing?
A. As in love and war so is in medicine the is no always nor never. It is probably the marfan that caused your neighbor kid the lens dislocation but you can never know for sure.More discussions about connective tissue
