In cases like this, the body will form a scar in the area using a special type of cartilage called fibrocartilage. [2] Fibrocartilage is a tough, dense, and fibrous material that helps fill in the torn part of the cartilage; however, it is not an ideal replacement for the smooth, glassy articular cartilage that normally covers the surface of ...
In embryogenesis, the skeletal system is derived from the mesoderm germ layer. Chondrification (also known as chondrogenesis) is the process by which cartilage is formed from condensed mesenchyme tissue, which differentiates into chondroblasts and begins secreting the molecules (aggrecan and collagen type II) that form the extracellular matrix.
Elastic cartilage, fibroelastic cartilage or yellow fibrocartilage [1] is a type of cartilage present in the pinnae (auricles) of the ear giving it shape, [2] provides shape for the lateral region of the external auditory meatus, [3] medial part of the auditory canal [3] Eustachian tube, corniculate and cuneiform laryneal cartilages, [3] and the epiglottis.
An intervertebral disc (British English), also spelled intervertebral disk (American English), lies between adjacent vertebrae in the vertebral column.Each disc forms a fibrocartilaginous joint (a symphysis), to allow slight movement of the vertebrae, to act as a ligament to hold the vertebrae together, and to function as a shock absorber for the spine.
The articular disc (or disk) is a thin, oval plate of fibrocartilage present in several joints which separates synovial cavities. This separation of the cavity space allows for separate movements to occur in each space.
Histologic specimen being placed on the stage of an optical microscope Human lung tissue stained with hematoxylin and eosin as seen under a microscope. Histology, [help 1] also known as microscopic anatomy or microanatomy, [1] is the branch of biology that studies the microscopic anatomy of biological tissues.
A fibrocartilage callus is a temporary formation of fibroblasts and chondroblasts which forms at the area of a bone fracture as the bone attempts to heal itself. The cells eventually dissipate and become dormant, lying in the resulting extracellular matrix that is the new bone. The callus is the first sign of union visible on x-rays, usually 3 ...
The classical tools for studying tissues are the paraffin block in which tissue is embedded and then sectioned, the histological stain, and the optical microscope. Developments in electron microscopy, immunofluorescence, and the use of frozen tissue-sections have enhanced the detail that can be observed in tissues.
