Mast cells secrete histamine. This tissue resembles areolar connective tissue, but the only fibers in its matrix are the reticular fibers, which form a delicate network. Cartilage is a flexible connective tissue found in many areas in the bodies of humans and other animals, including the joints between bones, the rib cage, the ear, the nose, the elbow, the knee, the ankle, the bronchial tubes, and the intervertebral discs. This tissue gives bones their smooth, white, and solid appearance, and accounts for 80% of the total bone mass of an adult skeleton. All rights reserved. (adsbygoogle = window.adsbygoogle || []).push({}); Connective tissue is incredibly diverse and contributes to energy storage, the protection of organs, and the body’s structural integrity. It is found in the intervertebral discs of the bony vertebrae and knee meniscus. Connective Tissue Found everywhere in the body Includes the most abundant and widely distributed tissues Functions of CT Binds body tissues together (Binding of organs -- Ex. Adipose tissue: Yellow adipose tissue in paraffin section with lipids washed out. A) Fibrocartilage B) Areolar C) Spongy bone D) Elastic Connective Areolar 13 Tendons, … These fibers allow the tissues to recoil after stretching. Connective tissue fibers provide support. b. Mesenchyme These tissues are widely distributed and serve as a universal packing material between other tissues. This tissue forms the fascia, which is a fibrous membrane that wraps around the muscles, blood vessels, and nerves. Collagen fibers are the most abundant CT fibers. It is an atypical connective tissue since it does not bind, connect, or network with any body cells. d. Plasma cell They usually stain pink and are the thickest fiber. White adipose tissue Collagen fibers and reticular fibers both belong to the collagen family, of which there are over 20 different types. How to solve: Which cell type is most abundant in connective tissue? b. Elastic fiber Bone tissue is also called the osseous tissue. Adipose tissue is found in specific locations, referred to as adipose depots. b. Purkinje fibers are specialized muscle fibers. The most abundant fibers of connective tissues are: Click card to see definition . There are three types of protein fibers; collagen, elastic and reticular. This tissue is found in areas where tension is exerted from many different directions. These collagen fibers are slightly wavy and can stretch a little bit. Top of Page. A: Collagen Fibers are found in most supporting tissues and collagen is the most abundant protein in the body (Wheaters). Loose connective tissue 3. Mesenchyme is embryonic connective tissue. c. Histiocyte The most abundant fibers of connective tissues are A) Reticular B) Elastic C) Collagen D) Glycoprotein Reticular 12 Which of the following is a loose connective tissue? Connective tissue can be sub-classified into connective tissue proper, specialized connective tissue and embryonic connective tissue. White adipose tissue is unilocular adipose tissue. Collagen. Connective tissue has a wide variety of functions that depend on the types of cells and the different classes of fibers involved. Because it is compressible and resists tension well, fibrocartilage is found where strong support and the ability to withstand heavy pressure are required. It is composed of proteoglycans and cell adhesion proteins that allow the connective tissue to act as glue for the cells to attach to the matrix. This is a blend of hyaline cartilage and dense regular connective tissue. Mast cells also secrete heparin, SRS-A (slow reacting substance of anaphylaxis, ECF-A (eosinophilic chemotactic factor of anaphylaxis. Hematoxylin and eosin stain is the most commonly used tissue stain for routine histological examination. There are three types of fibers found in connective tissue: collagen fibers, elastic fibers, and reticular fibers. The major functions of connective tissue include: Connective tissues encompass a diverse array of tissue types that are involved in binding and supporting body structure and tissues. c. Reticular fiber Plasma cells are derived from B lymphocytes. Dense connective tissue is divided into 1) dense regular, 2) dense irregular, 3) elastic. They have great tensile strength.They are the most abundant type of fibers in the body.T There are many tpes of collagen fibers, them ost common types of collagen fibers are: Type I collagen fibers: Are most abundant are found in: Dermis of skin; Fascia Most abundant are the fibres composed of the protein collagen. 2. This type of tissue persists into adulthood. This histology test bank is also useful for the histology questions on the USMLE (USMLE step 1). Image Source: austincc.edu. Silver impregnation, such as with a reticular stain, can be used to visualize reticular fibers. This is is the most abundant of all cartilage in the body. Like to the timber framing of a house, the connective tissue provides structure and support throughout the body. This is especially seen in the arterial blood vessels and walls of the bronchial tubes. c. Sudan stain What is areolar tissue? What type of adipose tissue tends to decrease as humans age? Loose irregular connective tissue is areolar tissue. The most abundant fiber in connective tissues is a tough protein called collagen. Collagen fibers, the most abundant of the connective tissue fibers, are produced by fibroblasts and stain pink with eosin. This is present during fetal development and then decreases after birth. a. The histiocyte is a connective tissue macrophage. Although it also cushions and insulates the body glassy when viewed under microscope. Relatively high compressive strength, and ground substance and fibers make up extracellular. With lipids washed out is relatively hard and lightweight in nature histological examination is comprised of cells and make.
