What is a fibrocartilage?
Fibrocartilage is the tough, very strong tissue found predominantly in the intervertebral disks and at the insertions of ligaments and tendons; it is similar to other fibrous tissues but contains cartilage ground substance and chondrocytes.
What do you mean by chondrocytes?
Chondrocytes are the cells responsible for cartilage formation, and they are crucial for the process of endochondral ossification, which is useful for bone development.
What is gristle in the body?
Gristle. A dense form of connective tissue performing various functions in the body such as providing bearing surfaces in the joints, flexible linkages for the ribs, and a supportive tissue in which bone may be formed during growth.
Which type of connective tissue is avascular and Aneural?
Cartilage is an avascular, aneural, and alymphatic connective tissue with a limited capacity caused by low mitotic activity of its resident cells, chondrocytes.
What is a hole in the bone called?
The foramen is the hole is an opening or groove in the bone that allows blood vessels and nerve to enter the bone.
What is fibroblast function?
Fibroblasts appear to play an important role in wound healing, and this activity is thought to be regulated by cells known as fibrocytes residing in the tissue stroma. Following tissue injury, fibroblasts migrate to the site of damage, where they deposit new collagen and facilitate the healing process.
What is the difference between gristle and cartilage?
is that gristle is cartilage; cartilage present, as a tough substance, in meat while cartilage is (anatomy) a type of dense, non-vascular connective tissue, usually found at the end of joints, the rib cage, the ear, the nose, in the throat and between intervertebral disks.
What are 3 types of connective tissue?
Connective tissue can further be broken down into three categories: loose connective tissue, dense connective tissue, and specialized connective tissue. Loose connective tissue works to hold organs in place and is made up of extracellular matrix and collagenous, elastic and reticular fibers.
What is the difference between vascular and avascular tissue?
Vascular tissues in the human body have blood vessels like veins, arteries and capillaries, while avascular tissues do not. For example, muscle tissue is vascular, or vascularized. Cartilage is another type of avascular tissue.
What connective tissue means?
(kuh-NEK-tiv TIH-shoo) Tissue that supports, protects, and gives structure to other tissues and organs in the body. Connective tissue also stores fat, helps move nutrients and other substances between tissues and organs, and helps repair damaged tissue.
What is the definition of avascular tissue?
Answer Wiki. An avascular tissue is a type of tissue that lacks a direct blood supply to it. Typically blood vessels such as arterial and venous networks are absent in these types of tissues. Such tissue will tend to be present right next to a highly vascular tissue through which, it can receive nutrients via circulation.
What is the avascularity of the brain?
An avascular tissue, is an area of tissue devoid of any blood vessels, hence there is no vascularity. Skin, muscle, bone, nerves, are said to be avascular if their blood supply fails. If it is not restored within a short period of time, three or four minutes for the brain, avascular tissue will die and become necrotic.
Is cartilage vascular or avascular?
All cartilage is avascular. Most cartilage is located inside of the joint capsule, surrounded by the synovium. The joint capsule receives ample blood supply while the contents of the joint rely on the synovial fluid.
Why is the epidermis avascular?
Moreover, some connective tissues that contain elastic fibers are also avascular. The main function of the epithelial tissue of the skin is to protect the underneath tissues from mechanical abrasion. Therefore, the absence of vessels in the epidermis becomes an advantage. Figure 2: Avascularized Epidermis
