ii. Dense Irregular CT
Bundles of collagen are irregularly arranged. Found in the body where pulling forces are multidirectional. This tissue usually occurs in sheets such as the dermis of the skin.
Example:
iii. Elastic CT
Branching elastic fibres dominate with fibroblasts seen between the fibres. This CT is quite strong and can recoil to its original shape after being stretched.
Example:
C. Cartilage :
Consists of collagen and elastic fibres embedded in Chondroitin Sulphate (agel-like component of the ground substance). Cartilage can endure more stress than loose and dense connective tissues due to its collagen fibres. The cells of mature cartilage contain large numbers of chondrocytes within spaces called Lacunae in the extracellular matrix. A covering of dense irregular CT called perichondrium surrounds the surface of most cartilage. Cartilage is avascular and insensitive. For this reason, damaged cartilage is slow to heal, and often regains limited function.
There are three types :
i. Hyaline cartilage
Has thin, fine collagen fibres and prominent chondrocytes found in the lacunae. Most hyaline cartilage is surrounded by perichondrium. Hyaline is the most abundant cartilage in the body. It provides flexibility, support, reduces friction, and adsorbs shock. However, this cartilage is the weakest of the three types.
