GENERAL HISTOLOGY

Detailed explanation-1: -Dense regular connective tissue has great tensile strength that resists pulling forces especially well in one direction. DRCT has a very poor blood supply, which is why damaged tendons and ligaments are slow to heal.

Detailed explanation-2: -Most connective tissues have a good blood supply but some do not. Numerous cell types are found in connective tissue. Three of the most common are the fibroblast, macrophage, and mast cell.

Detailed explanation-3: -Cartilage does not contain blood vessels (it is avascular) or nerves (it is aneural).

Detailed explanation-4: -Cartilage is composed of specialized cells called chondroblasts and, unlike other connective tissues, cartilage does not contain blood vessels.

Detailed explanation-5: -Cartilage. Cartilage is the avascular connective tissue that connects bones at joints and comprises walls of upper respiratory airways and external ear. It is surrounded by perichondrium, a layer of dense connective tissue. The perichondrium is rich in blood vessels and supplies the cartilage.
