Connective tissues The four types of connective tissues allow movement and flexibility in your body. These types are called cartilage, ligaments, tendons and joints.
It is composed of cells called chondrocytes which are dispersed in a firm gel-like ground substance, called the matrix. Cartilage is avascular and nutrients are diffused through the matrix. Cartilage resists friction and compression, and is an elastic and gelled tissue between your bones and joints. Cartilage is found in the joints, the rib cage, the ear, the nose, in the throat and between intervertebral disks.
A ligament is a band of fibrous tissue that connects bones or cartilage, serving to support and strengthen joints. Ligaments connect bones to other bones to form a joint. A tendon is a fibrous, strong, connective tissue that connects muscle to bone. The origin of a tendon is where it joins to a muscle.A joint is the place where two bones meet, which often allows movement in that area. Dense connective tissue, also called dense fibrous tissue, has collagen fibers as its main matrix element. Crowded between the collagen fibers are rows of fibroblasts, fiber-forming cells, that manufacture the fibers. Dense connective tissue forms strong, rope-like structures such as tendons and ligaments.
An example of a homeostatic imbalance of this is Marfan syndrome, a connective disorder characterized by unusually long limbs. Marfan syndrome is also an example of a dominant negative mutation. The disease also affects other bodily structures including the lungs, eyes, heart and blood vessels in less obvious ways. There is no cure for Marfan syndrome, but effective treatment allows many people with the disorder to live normally.Reference:1. “Connective Tissue”. Wikipedia, the Free Encyclopedia. Oct.
