Location: Pads (menisci) within the knee joint. Generally found in the nose, larynx, wind pipe, and bronchial tubes leading to the lungs, it is made up of mostly a gel-like substance called collagen and a fibrous structure, or matrix, which normally encloses the . It owes its flexibility and toughness to the fibrous tissue, and its elasticity to the cartilaginous tissue.

It's main function is to reduce friction between the joints . Be able to identify cells and structures in a sections of cartilage (e.g.
It is also present at the tendon bone interface, where there is a transition from the soft tendon to the calcified and non-calcified fibrocartilage before becoming bone. Longitudinal fibroblasts and a parallel arrangement of collagen fibers are found at the tendinous area Elastic cartilage, sometimes referred to as yellow fibrocartilage, is a type of cartilage that provides both strength and elasticity to certain parts of the body, such as the ears. Description. Fibrocartilage is a special type of connective tissue intermediate between dense connective tissue and hyaline cartilage. Under the microscope, tissue samples appear clear. Main Difference - Fibrocartilage vs Hyaline Cartilage. Elastic cartilage, which is yellow in appearance, is more pliable…. . skeleton, very hard and rigid. Fibrocartilage definition, a type of cartilage having a large number of fibers. The triangular fibrocartilage complex (TFCC) is a band of cartilage that cushions the area in the wrist where the ulna, lunate, and triquetrum intersect. Therefore, a precise description of TFCC injuries is valuable for treatment planning.
A primary function of the TFCC is to facilitate forearm rotation with a flexible connection between the distal .
parts of fibrocartilage that aren't DRCT. Fibrocartilage (Figure 7) has many collagen fibers, making it the strongest type of cartilage. Audio Histology Slide: Fibrocartilage. bone - what does it contain.
Elastic cartilage looks very similar to hyaline cartilage under a microscope, and special stains must be used to show the otherwise invisible elastic fibers that give this particular cartilage type its name.Like hyaline, elastic cartilage also has single or multiple chondrocytes housed within spaces called lacunae. Cartilages are a type of connective tissue that is made up of chondrocytes and an extracellular matrix.
