Localized PVNS of the knee can occur in any location but its confinement to the posterior com … It is a tissue that lack of red corpuscles, platelets and proteins. There are four main tissues in the body - epithelium, muscle, connective tissue and nervous tissue. Connective tissue is made up of a large amount of intercellular matrix of fibres or both and living cells. TISSUES Human body is made up of four basic tissues: epithelial tissue, connective tissue, muscular tissue and nervous tissue. Dense connective tissue is commonly classified as either dense irregular connective tissue, with a random orientation of the fiber bundles, or dense regular connective tissue, in which fibers are oriented in a regular pattern. Pigmented villonodular synovitis (PVNS) is an uncommon entity involving articular or extra-articular tissues and maybe localized or diffuse in extent. The retinal pigment epithelium is a fundamental component of the retina that plays essential roles in visual functions. Functions of Connective Tissues. Connective tissue functions . d. Compare and contrast the roles of individual cell types and fiber types within connective tissue. Connective tissues with special characteristics of structure and function include elastic, reticular, and pigmented types. Connective Tissue: Adipocytes. The main bulk of the tissue consists of intercellular. Tissues of the human body can be classified under 4 major sub-types: epithelial, nervous, muscle, and connective (Delforge, 2002). The skin is composed of two main layers: the epidermis, made of closely packed epithelial cells, and the dermis, made of dense, irregular connective tissue that houses blood vessels, hair follicles, sweat glands, and other structures. Beneath the dermis lies the hypodermis, which is composed mainly of loose connective and fatty tissues. Specialized pigmented macrophages, melanocytes, are distributed in this layer and have a role in absorption of excess radiation. Major functions of connective tissue include: 1) binding and supporting, 2) protecting, 3) insulating, 4) storing reserve fuel, and 5) transporting substances within the body. The primary elements of connective tissue . Epithelial Tissue is one of the four types of tissue (epithelial, muscular, connective, and nervous) in animals which consists of closely aggregated polyhedral cells adhering firmly to one another, forming cellular sheets that line the interior of hollow organs and cover the body surface. In this type of tissue, there is a loose arrangement of cells and the cells are scattered in an extracellular matrix. They also provide cohesion and internal support. Connective Tissue Function. It contains high quantities of water, several types of cells, and a fibrous extracellular matrix.The connective tissue of an organ is usually referred to as the stroma.This tissue type can have very different structures according to the proportions of its components. 8 Pigmented Tissue Vertebrate Histology (ZOO 415) Monday, October 18, 2010 Examples: choroid of the eye and lamina fuscaof the sclera of •Skin is composed of two distinct tissues: Epidermis and Dermis -hair, nails and skin glands are modified epidermal structures •Hypodermis is fatty connective tissue under the skin. -Thin Skin (1-2 mm) covers most of the body and has hair follicles, sweat glands and oil glands. They are a loose array of random fibers that has a wide variety of cell type. There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. 3. Function: They help in synthesis of γ-globulin. Regulative. It's located between the epidermis and the subcutaneous tissue. Neural tissue. Furthermore, it provides protection against infection, gives passage to nerve and blood vessels through other tissues and fixes organs together. Connective tissue is found between other tissue types and organs. a. Brace the free gingiva against the tooth b. Suspends the tooth in its bony socket c.

It contains connective tissue, blood capillaries, oil and sweat glands, nerve endings, and hair follicles. Cuboidal iii. The main bulk of the tissue consists of intercellular. Connective. It binds the different organs together and enables the passage of nerves and blood vessels through other tissues of the body. Each muscle is surrounded by a connective tissue sheath called the epimysium. Fats/bones 3. Pigment connective tissues are found in dermis of skin, iris and choroid coat of eye. It is the only fluid connective tissue in the body. The dermis is split into two parts—the papillary dermis, which is the thin, upper layer, and the reticular dermis . 2) Always has one free (apical) surface open to outside the body or inside (cavity) an internal organ. Connective tissue proper - It is made up of a semisolid matrix and cells. Epithelial tissue, also referred to as epithelium, refers to the sheets of cells that cover exterior surfaces of the body, lines internal cavities and passageways, and forms certain glands. Connective tissue is found deep and in-between the other three types of tissue: epithelium, nervous, and muscle tissue. It contains high quantities of water, several types of cells, and a fibrous extracellular matrix.The connective tissue of an organ is usually referred to as the stroma.This tissue type can have very different structures according to the proportions of its components.
