PERICHONDRIUM Meaning and Definition

1. The perichondrium is a connective tissue sheath that surrounds and provides structural support to cartilage in the body. It consists of two distinct layers: an outer fibrous layer and an inner cellular layer.

   The outer fibrous layer, also known as the fibrous perichondrium, is composed of dense irregular connective tissue. It is responsible for protecting the underlying cartilage and providing mechanical support. Additionally, it serves as a barrier to prevent blood vessels from penetrating the cartilage.

   The inner cellular layer, known as the chondrogenic layer or cambium layer, is made up of undifferentiated cells called chondroblasts. These cells have the potential to differentiate into chondrocytes, which are the mature cells responsible for maintaining cartilage. The inner layer actively participates in the growth and development of cartilage tissue by secreting extracellular matrix components.

   The perichondrium plays a vital role in the growth, maintenance, and repair of cartilage. It is richly supplied with blood vessels, which deliver oxygen and nutrients to the cartilage cells. It also contains a network of nerves that sense pain and contribute to the overall sensory function of the cartilage. Furthermore, the perichondrium is involved in the process of endochondral ossification, where cartilage can be replaced by bone during skeletal development.

   Overall, the perichondrium is an essential component in maintaining the integrity and functionality of cartilage throughout the body.

2. In anat., the fibrous membrane covering cartilages.
