D. long bone

Answer 1

ANSWER:

The humerus is a long bone which consists of a shaft (diaphysis) and two extremities (epiphysis). It is the longest bone of the upper extremity

Answer 2

The humerus, located between the shoulder and elbow joints, is classified as a long bone. It connects to other bones to enable movement of the upper limb and fits the characteristics of long bones: cylindrical and longer than wide. So the correct option is D.

Step-by-step explanation:

The humerus is the single bone found in the upper arm between the shoulder and elbow joints. When classifying bones by their shapes, the humerus falls into the category of a long bone. Long bones are characterized as being cylindrical, longer than they are wide, and function as levers to facilitate movement. This classification of the humerus as a long bone is consistent with its articulated connections at the shoulder with the scapula and at the elbow with the radius and ulna, as well as its overall structure and function in the upper limb.
