Proliferative vitreoretinopathy (PVR) is a disease leading to the formation of contractile preretinal membranes (PRMs) and is one of the leading causes of blindness. Connective tissues develop from the mesodermal cells of the embryo. Functionally, the mammary glands produce milk; structurally, they are modified sweat glands.Mammary glands, which are located in the breast overlying the pectoralis major muscles, are present in both sexes, but usually are functional only in the female.. Externally, each breast has a raised nipple, which is surrounded by a circular pigmented area called the areola. Connective tissue proper contains cells surrounded by the fibers and ground substance of the extracellular matrix. ground substance. Based on the variation of quantity and arrangement of fibers within the matrix, the ideal connective tissue is classified into two main types – loose connective tissue and dense connective tissue. (E) Mucoid Connective Tissue: In addition to above mentioned connective tissues, mucoid tissue occurs as a foetal or embryonic connective tissue. with pigmented fungiform papillae. The circular area of pigmented (darkly shaded) skin surrounding the nipple on the breast. Pigment Cells: Some of the connective tissue cells are found to possess pigment granules and such cells are more common in the skin, choroid coat of the eye, pia mater, etc. The fibroblasts of connective tissue migrate to site of injury and deposit collagen fibers, resulting in fibrous scar tissue. Pigmented spots including age spots or "liver spots" may appear in sun-exposed areas. Here it looks like a pink stripe underneath the black stripe.

In Unicellular Organisms, all vital cellular functions like digestion, respiration, excretion, etc., are performed by a single cell, but Multicellular Organisms have a complex body organization. Loose connective tissue is the most widely distributed of all connective tissues. Most are well-defined encapsulated masses found just beneath the skin or between muscles and other connective-tissue structures. –Loose connective tissue allows the skin to be bound with underlying muscles. Compare loose connective tissue to dense connective tissue. Functionally, the mammary glands produce milk; structurally, they are modified sweat glands.Mammary glands, which are located in the breast overlying the pectoralis major muscles, are present in both sexes, but usually are functional only in the female.. Externally, each breast has a raised nipple, which is surrounded by a circular pigmented area called the areola. II. Connective tissue growth factor (CTGF) has been identified as a possible key determinant of progressive tissue fibrosis and excessive scarring. It involves the spatial and temporal synchronization of a variety of cell types with distinct roles in the phases of hemostasis, inflammation, growth, re-epithelialization, and remodeling. Immature, unspecialized form of connective tissue in animals, consisting of cells embedded in a thin extracellular matrix. Gram-positive cocci, arranged in pairs or chains.

Proliferative vitreoretinopathy (PVR) is a disease leading to the formation of contractile preretinal membranes (PRMs) and is one of the leading causes of blindness. Connective tissues develop from the mesodermal cells of the embryo. Functionally, the mammary glands produce milk; structurally, they are modified sweat glands.Mammary glands, which are located in the breast overlying the pectoralis major muscles, are present in both sexes, but usually are functional only in the female.. Externally, each breast has a raised nipple, which is surrounded by a circular pigmented area called the areola. Connective tissue proper contains cells surrounded by the fibers and ground substance of the extracellular matrix. ground substance. Based on the variation of quantity and arrangement of fibers within the matrix, the ideal connective tissue is classified into two main types – loose connective tissue and dense connective tissue. (E) Mucoid Connective Tissue: In addition to above mentioned connective tissues, mucoid tissue occurs as a foetal or embryonic connective tissue. with pigmented fungiform papillae. The circular area of pigmented (darkly shaded) skin surrounding the nipple on the breast. Pigment Cells: Some of the connective tissue cells are found to possess pigment granules and such cells are more common in the skin, choroid coat of the eye, pia mater, etc. The fibroblasts of connective tissue migrate to site of injury and deposit collagen fibers, resulting in fibrous scar tissue. Pigmented spots including age spots or "liver spots" may appear in sun-exposed areas. Here it looks like a pink stripe underneath the black stripe. The circular area of pigmented (darkly shaded) skin surrounding the nipple on the breast. 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. Black Tongue: Causes, Symptoms, and Treatments Pigmented fungiform papillae of the tongue (PFPT) were first described by Leonard [2] in 1905 as a benign condition of oral pigmentation characterized by localized hyperpigmentation confined to fungiform papillae. This lower quantity of melanin is genetically determined but is further regulated by exposure to ultraviolet light mainly from sunlight and less frequently from tanning beds. Clinically, multiple brown–black pigmented areas are noted adjacent to reticular, erosive or vesicular lesions. Also Read: Plant Tissue System.
