White fibrous cartilage

White fibrous cartilage Chart

Cell types: Chondrocyte

Differential diagnosis:
Othr cartilage such as hyaline cartilage do not have fibers except in the perichondrium. Yellow cartilage has netwok of fibers which do not run parallel and spongy bone has a network of mesenchyme, and is not as amorphous in ground substance.

Diagnostic Features:
a. Tissue is compact (e.g. liver) and sclerous in view of hardness and relative homogeneity.
b. Cartilage tissue can be recognized in view of ground glass transparent appearance and the lacunae embedded chondrocytes.
c. Fibers are available in tissue cartilage and therefore distinguishes this type of cartilage from hyaline cartilage.
d. Presence of strong parallel collagenous fibers running in waves.
e. Examples include intervertebral discs, articular disc, labra glenoidale and acetabulare, in bony grooves which lodge tendons, in intramembranous ossifying articular ends and patella tendinous insertion.

Tissue

Gross

Level 1: Select compact
Level 2: Select sclerous tissue from list of sclerous, muscular, connective, organ-glands and nervous tissues.
Level 3: Select homogenous to suggest the ground glass substance appearance of the cartilage.
Level 4: Select cartilage and not spongy bone since there is no visible intraparenchymal exuberant mesenchyme.

Also look for parallel running fibers which distinguish it from other cartilages.

Do you think this is the section of the articular disc, intervertebral disc, patella tendinous insertion or labra glenoidale-acetabulare? This may be difficult to tell.
