NEET PG DENTAL EXAM

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: -Cartilage is composed of specialized cells called chondroblasts and, unlike other connective tissues, cartilage does not contain blood vessels. Cartilage is classified in three types: 1) elastic cartilage, 2) hyaline cartilage, and 3) fibrocartilage, which differ in the relative amounts of these three main components.

Detailed explanation-3: -Cartilage, like bone, is surrounded by a perichondrium-like fibrous membrane. This layer is not efficient at regenerating cartilage. Hence, its recovery is slow after injury. The lack of active blood flow is the major reason any injury to cartilage takes a long time to heal.

Detailed explanation-4: -Epithelial tissues do not contain blood vessels and as such are avascular.
