Connective tissues are divided into three that are loose connective tissue, dense connective tissue and specialised connective tissue. Recall that the primary function of plasma cells is antibody secretion, so they are a prominent constituent of loose connective tissue wherever antigens may enter the body, such as the gastrointestinal, urogenital, and respiratory tracts. It mainly joins one tissue to another in the organs. c. connective tissue to muscle tissue. Connective tissues are divided into three groups: A. General feeling of being unwell. B. (c) Reticular fibres. 8 Pigmented Tissue Vertebrate Histology (ZOO 415) Monday, October 18, 2010 Examples: choroid of the eye and lamina fuscaof the sclera of It contains a pigment called haemoglobin which helps in transport of oxygen to every part of the body. A group of identical cells, combined with intercellular signalling, fulfill a specialized role in multicellular creatures. Salts and fibres may be found in the intercellular matrix, which is unique to a particular tissue and gives it distinct features. Each tissue type has a characteristic role in the body: Epithelium covers the body surface and lines body cavities. Connective tissue abnormalities can be caused by gene mutations or inherited faulty genes. It is composed primarily of connective tissue.

Upper eye fat is caused by the accumulation of fat in two compartments over the eyelid. The word hyaline means glass-like, and hyaline cartilage is a glossy, greyish-white tissue with a uniform appearance. Increasing evidence demonstrates that, beyond supplying nutrients to the outer retina, the different choroidal cells contribute to the retina's homeostasis, especially by paracrine signaling. In Cartilaginous connective tissue where Cartilage is an elastic material that serves as a cushion between the bones. (g) Mesenchyme cells give rise to different types of cells of connective tissue. These cells also release modified polysaccharides, which collect between cells and fibers and serve as a matrix (ground substance). Connective tissue is made up of cells, fibers, and a gel-like substance. The extra cellular matrix has nearly amorphous ground substance which is made of glycoproteins with associated mucopolysaccharides. Pigmented connective tissue 3. There are weight-bearing limb bones present, such as the long bones of the legs. It frequently serves as a scaffolding for the epithelium. The major function of this system is as a barrier against the external environment. By using our site, you What is the function of connective tissue class 9? The blood and the cells that make it up. It is sometimes known as the kissing muscle because it is used to pucker the lips. Connective tissues are characterized by an abundance of intercellular matrix with relatively few cells. Tissue is a phrase used to describe a group of cells that have a similar form and function. 1)The blood transports carbon dioxide and oxygen to all the parts of the body to every tissue and every cell. The cells of the epithelial tissue are arranged cellular sheets either in single or multiple layers. Cartilage is avascular, while dense connective tissue is poorly vascularized.
