Cartilage tissue: structure, functions and importance for the human body

What is cartilage tissue?

Cartilage tissue is a special form of supporting tissue that consists of cartilage cells (chondrocytes) and an extracellular matrix. This matrix contains collagen, elastin and proteoglycans, which give the cartilage elasticity and strength

Types of cartilage tissue

Hyaline cartilage: Reduces friction in joints and is found, for example, in the ribs and nasal septum.
Elastic cartilage: Flexible and elastic, e.g. in the pinna and epiglottis.
Fibrous cartilage: Particularly resistant, e.g. in intervertebral discs and menisci.

Functions of cartilage tissue

Shock absorber: Distributes mechanical loads in joints.
Structural support: Gives shape and stability to certain parts of the body.
Growth function: Basis for bone growth in childhood.

Diseases of the cartilage tissue

Osteoarthritis: Wear and tear of the joint cartilage that causes pain and stiffness.
Cartilage injuries: Common in joints such as the knee or shoulder.
Chondroma: Benign tumour, rarely with symptoms.

Care of the cartilage tissue

Exercise: Promotes the supply of nutrients to the cartilage.
Nutrition: Omega-3 fatty acids, vitamin D and calcium contribute to cartilage health.
Weight control: Reduces stress on joints and cartilage.

Worth knowing

Cartilage tissue contains no blood vessels and is supplied with nutrients via diffusion. It loses elasticity with age , which is why prevention through exercise and nutrition is important
