What is cartilage?

The video tutorial explains cartilage, a type of connective tissue, and its role in the human body. It covers the extracellular matrix, types of cartilage (hyaline, elastic, and fibrocartilage), and their specific characteristics and functions. The tutorial also discusses the growth processes of cartilage, including appositional and interstitial growth, highlighting the importance of cartilage in providing structural support and facilitating growth in the skeletal system.

What is the primary role of chondrocytes in cartilage?

• To form bone tissue

• To produce blood cells

• To create muscle fibers

• To maintain and produce the extracellular matrix

Which type of cartilage is most commonly found in the human body?

• Articular cartilage

• Hyaline cartilage

• Fibrocartilage

• Elastic cartilage

What distinguishes elastic cartilage from hyaline cartilage?

• Lack of chondrocytes

• Presence of type 1 collagen

• Higher concentration of proteoglycans

• Substantial amount of elastic fibers

Where is fibrocartilage typically found in the body?

• In the meniscus of the knee

• In the external ear

• In the tip of the nose

• In the tracheal rings

What is one of the main functions of cartilage in the human body?

• To conduct nerve impulses

• To absorb shock between articulating bones

• To produce red blood cells

• To store calcium

What is appositional growth in cartilage?

• Growth from the inside out

• Growth from the outside inwards

• Growth that stops after adolescence

• Growth that occurs only in fetal development

How does interstitial growth contribute to bone development?

• By lengthening long bones during growth

• By forming new bone tissue

• By increasing bone density

• By reducing bone mass
