Connective Tissue | Basic Histology

Connective tissue is one of the four basic types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue. It develops from the mesoderm. Connective tissue is found in between other tissues everywhere in the body, including the nervous system. In the central nervous system, the three outer membranes (the meninges) that envelop the brain and spinal cord are composed of connective tissue. All connective tissue consists of three main components: fibers (elastic and collagenous fibers),[1] ground substance and cells. Not all authorities include blood[2] or lymph as connective tissue because they lack the fiber component. All are immersed in the body water. The cells of connective tissue include fibroblasts, adipocytes, macrophages, mast cells and leucocytes.

Connective tissue can be broadly classified into connective tissue proper and special connective tissue.[5][6] Connective tissue proper consists of loose connective tissue and dense connective tissue (which is further subdivided into dense regular and dense irregular connective tissues.)[7] Loose and dense connective tissue are distinguished by the ratio of ground substance to fibrous tissue. Loose connective tissue has much more ground substance and a relative lack of fibrous tissue, while the reverse is true of dense connective tissue. Dense regular connective tissue, found in structures such as tendons and ligaments, is characterized by collagen fibers arranged in an orderly parallel fashion, giving it tensile strength in one direction. Dense irregular connective tissue provides strength in multiple directions by its dense bundles of fibers arranged in all directions.

Special connective tissue consists of reticular connective tissue, adipose tissue, cartilage, bone, and blood.[8] Other kinds of connective tissues include fibrous, elastic, and lymphoid connective tissues.[9] Fibroareolar tissue is a mix of fibrous and areolar tissue.[10] Fibromuscular tissue is made up of fibrous tissue and muscular tissue. New vascularised connective tissue that forms in the process of wound healing is termed granulation tissue.[11]

Type I collagen is present in many forms of connective tissue, and makes up about 25% of the total protein content of the mammalian body

Thank you for you short and brief explanation, i need to your videos

[shivanikushwaha]

mam sol to gel in consistency kya h in ground substance

[sakshigoyal]

nice explanation.

a request ma'am, kindly try to explain at a slower pace.

[ਨਵਦੀਪਸਿੰਘ]

Mam also upload video on cranial nerves

[shabimalik]

English ko choro aese viral nhi ho gi interview k leye nhi ai ap yaha smjhein urdu mn

[kavitachouhan]

Ma'am I request you to upload one more video I think one week back the histology of limbus(changes occur in the corneal layers at corneoscleral junction) with microscopic but you didn't uploaded

[ammu...]

Ma'am would you plz tell me the important diagrams in Anatomy
