Bone And Osseous Tissue

2.

What are the functions of bone (check all that apply)

Protection
Support/movement
Energy
Triglyceride storage (fat)
Blood cell production
Mineral homeostasis
Vitamin production

Correct Answer(s)

A. Protection
A. Support/movement
A. Triglyceride storage (fat)
A. Blood cell production
A. Mineral homeostasis

Explanation

Bones serve multiple functions in the body. They provide protection to vital organs, such as the skull protecting the brain and the ribcage protecting the heart and lungs. Bones also provide support and enable movement by acting as a framework for muscles to attach to and allowing for the movement of joints. Additionally, bones store triglycerides (fat) which can be used as an energy source when needed. They are also involved in the production of blood cells, specifically in the bone marrow. Lastly, bones play a role in mineral homeostasis by storing and releasing minerals, such as calcium and phosphorus, as needed by the body.

What is A?

Diaphysis
Distal Epiphysis
Proximal Epiphysis
Endosteum

Correct Answer

A. Proximal Epiphysis

Explanation

The proximal epiphysis refers to the end of a long bone that is closest to the main body of the bone. It is characterized by its rounded shape and is involved in the formation of joints. This region of the bone contains red bone marrow, which is responsible for the production of blood cells. The proximal epiphysis also serves as an attachment site for tendons and ligaments, allowing for movement and stability.

What is B?

Proximal epiphysis
Diaphysis
Distal Epiphysis
Periosteum

Correct Answer

A. Diaphysis

Explanation

The correct answer is Diaphysis. The diaphysis is the main shaft or middle part of a long bone. It is the region between the proximal and distal epiphysis. The diaphysis is primarily made up of compact bone and contains the medullary cavity, which houses the bone marrow.

What is C?

Proximal Epiphysis
Diaphysis
Distal Epiphysis
Endosteum

Correct Answer

A. Distal Epiphysis

Explanation

The distal epiphysis refers to the end of a long bone that is farthest away from the center of the body. It is responsible for connecting the bone to other bones or structures in the body. This region is important for joint movement and stability.

All _____ joints have a synovial cavity, or a space between the articulating bone.

Correct Answer
diarthrosis

Explanation
Diarthrosis joints are a type of synovial joint that have a synovial cavity, which is a space between the articulating bones. These joints allow for free movement and are found in areas like the knees, elbows, and shoulders. Therefore, the correct answer is diarthrosis.
