Question

The function of this type of bone is to provide strength and stability:

A. Long bone
B. Flat bone
C. Irregular bone
D. Sesamoid bone

Answer 1

Flat bones, such as the skull, ribs, and sternum, are responsible for providing strength and stability to the body due to their structure consisting of compact and spongy bone layers.

Step-by-step explanation:

The student has asked about which type of bone is responsible for providing strength and stability. The correct answer to this is B. Flat bone. Flat bones are characterized by their thin, flat appearance, which is often slightly curved. They consist of two parallel layers of compact bone with a layer of spongy bone sandwiched in between. This structure allows them to provide significant protection for internal organs as well as extensive surfaces for muscle attachment, thereby contributing to both strength and stability of the skeletal structure. Notable examples include bones like the skull, ribs, and sternum. These bones differ from long bones, which are built for weight support and movement, and sesamoid bones, which are embedded in tendons to protect against compressive forces like the patella (knee cap). Irregular bones like vertebrae have complex shapes and provide protective and supportive roles but do not primarily contribute to providing strength and stability in the same way flat bones do.

Answer 2

The function of this type of bone is to provide strength and stability: A. Long bone.

Step-by-step explanation:

Long bones, such as the femur and humerus, are characterized by their elongated shape, with a shaft (diaphysis) and distinct ends (epiphyses). The primary function of long bones is to provide structural support, strength, and stability to the body.

The length of long bones is essential for the leverage required in movement, and they also play a crucial role in supporting body weight.

The elongated structure of long bones contributes to their mechanical advantage in resisting bending and compression forces. The marrow cavity within the diaphysis contains bone marrow, which is crucial for blood cell production. Additionally, the epiphyses of long bones contribute to joint articulation, facilitating smooth and coordinated movement.

In summary, A. long bones are integral to the skeletal framework of the body, providing the necessary strength and stability for various physiological functions, including support, movement, and blood cell production. Their anatomical features and functions make them well-suited for their roles in the human body.
