Connective tissue

A bone is a rigid organ that constitutes part of the skeleton in most vertebrate animals. Bones protect the organs of the body, produce red and white blood cells, store minerals, help regulate acid-base homeostasis, provide structure and support for the body, and enable mobility and hearing. Bones come in a variety of shapes and sizes and have complex internal and external structures.

Cartilage is a resilient and smooth type of connective tissue. Semi-transparent and non-porous, it is usually covered by a tough and fibrous membrane called perichondrium. In tetrapods, it covers and protects the ends of long bones at the joints as articular cartilage, and is a structural component of many body parts including the rib cage, the neck and the bronchial tubes, and the intervertebral discs. In other taxa, such as chondrichthyans and cyclostomes, it constitutes a much greater proportion of the skeleton. It is not as hard and rigid as bone, but it is much stiffer and much less flexi

Mesenchyme () is a type of loosely organized animal embryonic connective tissue of undifferentiated cells that give rise to many tissues, such as skin, blood, or bone. The interactions between mesenchyme and epithelium help to form nearly every organ in the developing embryo.

type of adipose tissue

type of cartilage found on many joint surfaces

Fibrocartilage consists of a mixture of white fibrous tissue and cartilaginous tissue in various proportions. It owes its inflexibility and toughness to the former of these constituents, and its elasticity to the latter. It is the only type of cartilage that contains type I collagen in addition to the normal type II.

The adventitia ( ) is the outer layer of fibrous connective tissue surrounding an organ.

category including areolar tissue and adipose tissue

type of connective tissue

fatty tissue composed of white adipocytes

bars of hyaline cartilage that serve to prolong the ribs forward and contribute to the elasticity of the walls of the thorax

this contains more fiber and few cells than loose connective tissue

anatomical structure

material or tissue between animal or plant cells
