As the name implies, connective tissue serves a connecting function: It supports and binds other tissues in the body. Function of connective tissue: It binds various tissue together like skin with the muscles and muscles with bones. Epithelial is arranged in one or more layers and tightly packed together while connective is spread out and more fragile. It consists of a transparent, jelly-like sticky matrix containing numerous fibres and cells and abundant mucin. Transportation of nutrients and metabolites through direct diffusion between organs and connective tissue proper. They can be found all over the body. All tissues and organs in the body rely on connective tissue for support, protection, and structure. Sheets of connective tissue form capsules around organs, such as the liver and
Cartilages intercellular substance is solid and malleable, and it resists compression. Three types of connective tissues can be distinguished depending on the composition of the ground substance:(1) Connective tissue proper(2) Skeletal tissues(3) Vascular tissues. It is of further two types, i.e., white fibrous connective tissue (includes tendons and sheets) and yellow elastic connective tissue (includes ligaments and sheets).Functions: The tendons join the skeletal muscles with the bones, and the ligaments join bones to bones.

(e) Cell debris, microorganisms, and foreign substances are ingested by macrophages (= Histiocytes or Clasmatocytes). The chondrocytes (cartilage cells) secreting the matrix are embedded in spaces known as the lacunae (singular lacuna). The word hyaline means glass-like, and hyaline cartilage is a glossy, greyish-white tissue with a uniform appearance. The intercellular matrix, a nonliving substance, fills the spaces between the cells. Functions of the skin The fibrous connective tissue functions to provide strength to the inner layer of skin and strength, allowing it to handle forces of joint movements. The living cell types are red blood cells, also called erythrocytes, and white blood cells, also called leukocytes. Solve any question of Structural Organisation In Animals with:- Patterns of problems > Connective tissue, group of tissues in the body that maintain the form of the body and its organs and provide cohesion and internal support. They are named connective tissues because of their special function of linking and supporting other tissues/organs of the body. Your email address will not be published.

It may surprise you to learn that all sophisticated animals are made up of only four fundamental types of tissues. It is most widely distributed connective tissue in the animal body. The connective tissue sheath that surrounds muscle cells, the tendons that connect muscles to bones, and the skeleton that maintains the bodys positions are all examples of attachment and support. The same basic duties are well-organized by distinct groups of cells in the complex body of multicellular organisms. Privacy Policy, 2.Connecting tissues to one another. They also interact with the skeletal muscles that are linked to them to produce movement. Ground substance of extra cellular may be liquid, gel or solid. b. epithelial tissue to connective tissue. 4. The major function of this system is as a barrier against the external environment. i. 6.Transporting. Orbicularis oris muscle, also known as musculus orbicularis oris is a complex, multi-layered muscle which attaches through a thin, superficial musculoaponeurotic system to the dermis of the upper lip and lower lip and serves as an attachment site for many other facial muscles around the oral region.

Haematopoiesis- Formation of Blood Corpuscles. There are more than 200 disorders that affect the connective tissue. Loose connective tissue is composed of cells and fibers that are dispersed in a semi-fluid ground substance, such as areolar tissue found beneath the skin layer. Connective Tissue is defined as a group of tissues that help in binding and supporting other tissues or organs of the body. Cells, fibres, and ground substances make up connective tissue. Fig: Specialised Connective Tissues: (a) Cartilage, (b) Bone, (C) Blood. Connective tissue has a wide variety of functions that depend on the types of cells and the different classes of fibers involved. storage strength transport repair Ligament Fibrous bands which connects the adjacent bones , forming integral parts of joints. Adipose tissue is a connective tissue that specializes in the synthesis and storage of fat reserves. How many types of connective tissue are there? Connective tissue is the pathway by which blood vessels and nerves reach all parts of the body. Q.5. The orientation of fibers produces a regular or irregular pattern, resulting in dense regular and dense irregular tissues. Fibrous connective tissue contains fibroblast cells and is made up of fibrous fibers.

The fibrous components of loose areolar connective tissue, when viewed with the light microscope, appear as colourless strands of varying diameter running in all directions, and, if not under tension, these have a slightly undulant course. The connective tissues perform the following functions: They attach organs and tissues together. The connective tissues include several types of fibrous tissue that vary only in their density and cellularity, as well as the more specialized and recognizable variantsbone, ligaments, tendons, cartilage, and adipose (fat) tissue.
