Short And Easy Cartilage Quiz

Explanation
Hyaline cartilage is the correct answer because it is a type of cartilage that is found in the ribs and sternum. It is a smooth and flexible type of cartilage that provides support and structure to the ribs, allowing them to attach to the sternum. This type of cartilage is also found in other parts of the body, such as the nose and trachea, where it provides a smooth surface for movement and flexibility.

Explanation
Chondroblasts are the cells that produce new cartilage matrix. They are responsible for synthesizing and secreting the components of the extracellular matrix in cartilage. Once the matrix is produced, chondroblasts mature into chondrocytes, which are the mature cells found within the cartilage tissue. Chondrocytes maintain the cartilage matrix but do not actively produce new matrix. Osteoblasts and osteocytes, on the other hand, are involved in bone tissue formation and maintenance, not cartilage.

Explanation
The correct answer is fibrocartilage, hyaline, elastic. This is because fibrocartilage is a type of cartilage found in areas that require strong support and the ability to withstand pressure, such as the intervertebral discs and knee joints. Hyaline cartilage is the most common type of cartilage and is found in areas that require smooth movement and shock absorption, such as the nose and the ends of long bones. Elastic cartilage is found in areas that require flexibility and elasticity, such as the outer ear and the epiglottis.

Explanation
Articular cartilage is the correct answer because it is the only type of cartilage that lacks a perichondrium. The perichondrium is a layer of connective tissue that surrounds most types of cartilage, providing it with nutrients and helping with growth and repair. However, articular cartilage is found in the joints and does not have a perichondrium. This allows the cartilage to have a smooth surface and low friction, enabling smooth movement between bones in the joint.

Explanation
The epiglottis is not a hyaline cartilage. It is a flap of elastic cartilage located at the base of the tongue, which prevents food and liquids from entering the trachea during swallowing. Elastic cartilage contains more elastic fibers than hyaline cartilage, making it more flexible and able to withstand repeated bending and stretching. Therefore, the correct answer is false.
