Connective Tissue

Connective tissue            

Connective tissue is a fibrous tissue. It is one of the four traditional classes of tissues (the others being epithelia, muscle, and nervous tissue). Connective Tissue (CT) is found throughout the body. It has 3 main components; cells, fibers, and extracellular matrix. Connective tissue makes up a variety of physical structures including, tendons, blood, cartilage, bone, adipose tissue, and lymphatic tissue. CT is classified into three subtypes; Embryonic CT, Proper CT, and Special CT. The Proper CT subtype include dense regular CT, dense irregular CT, and loose CT. The Special CT subtype includes cartilage, bone, adipose tissue, blood. Hematopoietic Tissue (tissue that makes blood cells) and Lymphatic tissue.

Function :

  • Connecting a tissue with other tissue
  • Blind, attach or connect the various devices
  • Fill in and contribute to the body

Characteristics :

  • Location of connective tissue cells do not coincide, if it relates only to the end protoplasm
  • A component of intracellular or matrix Top of Form plasma cell shape, cytoplasm and cell nucleus bergranula bubble

Connective tissue comprising:

  1. Dense connective tissue: Composed of white collagen and elastin fibers, which tough and strong; matrix Meeting  or solid, example : tendons, ligaments, fascia.
  2. Loose connective tissue: Composed many kinds of cells: fibroblasts, plasma cells, macrophages, white blood cells, collagen and elastin fibers; loose matrix. Example : between and around the organs, blood vessels, under the skin.
  3. Fatty tissue or adipose: Forms a loose, composed of fat from cells   and thin-walled cavity in it there -full of fat drops. Example : under the skin, around kidneys, bearing joints, and in  long bone marrow.
  4. Bone tissue: It is a tissue of advocates, straightened up. Matrix had calcification or calcification which contains Ca-carbonate and Ca-phosphate; allows for hard and strong. The process of reinforcement is called: ossification. Includes compact and spongy bone tissue
  5. Cartilage tissue cartilage: Including ancillary network. Cell called chondrocytes, are in lacuna. Matrix elastic and solid by-prone in cells matrix cavity. In children derive embryonic connective tissue or mesenchymal and adults from membrane formed cartilage. Differentiated into: hyaline cartilage (trachea, bone surface joints), fibrous (disc between the vertebrae, the symphysis pubis) and elastic (ear, epiglottis, larynx )
  6. Blood tissue: Components: erythrocytes, leukocytes, platelets, blood plasma. Function: transports nutrients, the metabolism, immunity and blood clotting.
  7. Lymph  tissue : Component: lymphocytes, granulocytes; be in lymph fluid (consist water, glucose, fat and salt). Coronary circulating lymph, and can out from lymph vessels cavities wet tissue between cells. Function: transport of fat, protein and tissue fluid.
