- C.
Fibrous
- D.
Dense
Correct Answer
B. Outer-fibrous inner-chondrogenicExplanation
The perichondrium is a layer of connective tissue that surrounds cartilage. It consists of two layers: the outer layer, which is fibrous in nature, and the inner layer, which is chondrogenic. The fibrous outer layer provides strength and protection to the cartilage, while the chondrogenic inner layer contains cells that are responsible for the growth and maintenance of the cartilage tissue.Rate this question:

What compose the inner chondrogenic layer?
- A.
Chondroblasts
- B.
Dense connective tissue
- C.
Mesenchymal cells
- D.
Chondrocytes
Correct Answer
A. ChondroblastsExplanation
The inner chondrogenic layer is composed of chondroblasts. Chondroblasts are specialized cells that are responsible for producing and maintaining the extracellular matrix of cartilage. They secrete collagen and proteoglycans, which provide structural support and flexibility to the cartilage tissue. Chondroblasts eventually mature into chondrocytes, which are the main cell type found in mature cartilage. However, in the inner chondrogenic layer, the cells are actively producing and secreting the extracellular matrix, hence they are referred to as chondroblasts.Rate this question:

Articular cartilage lacks perichondrium
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Articular cartilage lacks perichondrium because it is a specialized type of cartilage that covers the ends of bones in joints. Unlike other types of cartilage, such as hyaline cartilage, articular cartilage does not have a perichondrium, which is a layer of connective tissue that surrounds and supports the cartilage. The absence of perichondrium in articular cartilage allows for smooth movement and reduces friction between bones in the joint.Rate this question:

Fresh elastic cartilage has a yellow color due to elastin in the elastic cartilage
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Fresh elastic cartilage has a yellow color due to the presence of elastin, a protein that provides elasticity to the tissue. Elastin is a key component of elastic cartilage, which is found in certain parts of the body such as the external ear and the epiglottis. The yellow color of elastic cartilage is a result of the unique composition and arrangement of elastin fibers within the tissue.Rate this question:

Correct Answer
D. Collagen fibers type 2+ elastic fibers+ proteoglycans and glycosaminoglycansExplanation
Elastic cartilage is composed of collagen fibers type 2, elastic fibers, proteoglycans, and glycosaminoglycans. Collagen fibers provide strength and support to the tissue, while elastic fibers allow the cartilage to be flexible and elastic. Proteoglycans and glycosaminoglycans help to maintain the structure and function of the cartilage by binding water molecules, providing hydration and cushioning.Rate this question:

- D.
Respiratory passages, intravertebral disks and pubic symphysis
Correct Answer
B. Intravertebral disks, attachment of certain ligaments and pubic symphysisExplanation
Fibrocartilage can be found in the intravertebral disks, attachment of certain ligaments, and the pubic symphysis. This type of cartilage is known for its ability to resist pressure and tension, making it ideal for areas that require support and cushioning. The intravertebral disks, which are located between the vertebrae in the spine, contain fibrocartilage to absorb shock and provide flexibility. Fibrocartilage is also found in certain ligament attachments, where it helps to stabilize joints and provide strength. Additionally, the pubic symphysis, which is the joint that connects the two pubic bones in the pelvis, contains fibrocartilage to allow for slight movement during childbirth.Rate this question:

Interstitial growth is the process that forms a new cartilage within an existing one, which is very active during endochondral ossification
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Interstitial growth is a type of growth that occurs within an existing cartilage. It is particularly active during endochondral ossification, which is the process of bone formation from a cartilage template. During interstitial growth, new cartilage cells are produced within the existing cartilage, leading to its expansion and ultimately the formation of new bone. Therefore, the statement that interstitial growth is very active during endochondral ossification is true.Rate this question:

What are the types of cartilage growth?
- A.
Interstitial growth, appositional growth
- B.
Interstitial growth only
- C.
It does not have growth to it
- D.
Primary and secondary growth
Correct Answer
A. Interstitial growth, appositional growthExplanation
Cartilage growth can occur through two processes: interstitial growth and appositional growth. Interstitial growth refers to the growth of cartilage from within, where chondrocytes within the cartilage matrix divide and secrete more matrix, allowing the cartilage to expand from within. Appositional growth, on the other hand, involves the addition of new layers of cartilage on the surface of existing cartilage, resulting in an increase in size. Therefore, the correct answer is interstitial growth and appositional growth.Rate this question:
