4.

Identify the structure at the pointer.
- Osteoblast
- Osteocyte
- Chondrocyte
- Chondroblast
Correct Answer

A. Osteoblast

Explanation

The correct answer is Osteoblast. Osteoblasts are bone-forming cells that are responsible for the production and secretion of the extracellular matrix of bone tissue. They play a crucial role in bone development and remodeling. Osteoblasts are typically found on the surface of bone and are involved in the mineralization of the bone matrix.

7.

Identify this tissue:
- Spongy bone
- Hyaline cartilage
- Fibrocartilage
- Elastic cartilage
Correct Answer

A. Fibrocartilage

Explanation

Fibrocartilage is a type of connective tissue that is found in areas that require both support and flexibility, such as the intervertebral discs, pubic symphysis, and menisci of the knee. It is composed of dense collagen fibers that provide strength and resilience. Fibrocartilage is able to absorb shock and withstand compression, making it ideal for areas that experience high levels of stress. It also contains chondrocytes, which are responsible for maintaining the extracellular matrix. Unlike hyaline cartilage, fibrocartilage has a more fibrous appearance due to the presence of collagen fibers.

What is the pointer on?
- Osteon
- Volkmann's canal
- Lacunae
- Haversian canal

9.

What is this structure?
- Canaliculi
- Osteon
- Lacunae
- Volkmann's canal
Correct Answer

A. Lacunae

Explanation

The image shows a cross-section of bone tissue, specifically an osteon. The small, dark spaces within the osteon are called lacunae. These spaces house osteocytes, which are mature bone cells responsible for maintaining the bone matrix.

10.

Identify this tissue:
- Compact bone
- Elastic cartilage
- Hyaline cartilage
- Spongy bone
Correct Answer

A. Compact bone

Explanation

Compact bone is a type of tissue found in the skeletal system. It is dense and hard, providing strength and support to the bones. Compact bone is composed of cylindrical units called osteons, which contain concentric layers of bone tissue surrounding a central canal that houses blood vessels and nerves. This tissue is responsible for the rigidity and durability of bones, allowing them to withstand mechanical stress and protect internal organs. Compact bone also plays a role in mineral storage, as it contains calcium and phosphate ions that can be released into the bloodstream when needed.

Identify the structure at the pointer:
- Osteoclast
- Chondroblast
- Chondrocyte
- Osteocyte
Correct Answer

A. Chondrocyte

Explanation

The correct answer is Chondrocyte. A chondrocyte is a cell found in cartilage tissue. It is responsible for producing and maintaining the extracellular matrix of cartilage. Chondrocytes are surrounded by the matrix and are typically found within small spaces called lacunae. They play a crucial role in cartilage growth, repair, and maintenance.

Rate this question:
14.

Identify this tissue:
- Fibrocartilage
- Elastic cartilage
- Hyaline cartilage
- Compact bone
Correct Answer

A. Elastic cartilage

Explanation

The correct answer is Elastic cartilage. Elastic cartilage is a type of connective tissue that contains elastic fibers, which provide flexibility and resilience. It is found in structures that require both support and elasticity, such as the external ear and the epiglottis. Unlike fibrocartilage, which is found in areas that require more strength, and hyaline cartilage, which is found in joints and the respiratory tract, elastic cartilage has a greater ability to recoil after being stretched. Compact bone, on the other hand, is a type of dense bone tissue that provides support and protection.

What are the thin lines that the pointer on?
- Osteon
- Haversian canal
- Lacunae
- Canaliculi
Correct Answer

A. Canaliculi

Explanation

Canaliculi are the thin lines that the pointer is on. Canaliculi are tiny channels that connect the lacunae (small spaces) within the bone tissue. They allow for communication and exchange of nutrients between osteocytes (bone cells) and the blood vessels within the Haversian canal. Canaliculi play a crucial role in maintaining the health and function of the bone tissue.

16.

Identify this tissue:
- Elastic cartilage
- Spongy bone
- Compact bone
- Fibrocartilage
Correct Answer

A. Spongy bone

Explanation

Spongy bone is a type of bone tissue that is characterized by its porous and honeycomb-like structure. It is found at the ends of long bones, in the vertebrae, and in other locations where bones need to be lightweight but still provide support. Spongy bone contains trabeculae, which are small, interconnected plates and rods that give it its sponge-like appearance. This tissue is responsible for providing strength and flexibility to the bone, as well as housing bone marrow and facilitating the exchange of nutrients and waste products.

18.

Identify the structure at the pointer:
- Osteon
- Canaliculi
- Lacunae
- Volkmann's canal
Correct Answer

A. Lacunae

Explanation

Lacunae are small spaces or cavities within the bone matrix that house osteocytes, which are mature bone cells. These lacunae are interconnected by tiny channels called canaliculi, allowing for communication between the osteocytes. Volkmann's canals, on the other hand, are larger channels that run perpendicular to the long axis of the bone, providing a pathway for blood vessels and nerves. Therefore, the structure at the pointer is the lacunae, which are small spaces within the bone matrix housing osteocytes.
