Which of the following are components of the forelimb?

The correct choice highlights the primary bones found in the forelimb of a mammal. The components of the forelimb include the humerus, radius, ulna, carpals, metacarpals, and phalanges.

• The humerus is the upper bone of the forelimb that connects to the shoulder, while the radius and ulna are the two long bones of the forearm.

• Carpals are the small bones that form the wrist, connecting the forearm to the hand.

• Metacarpals are the long bones in the hand, and phalanges represent the bones in the fingers.

These components work together to provide structure, support, and enable movement in the forelimb. An understanding of these bones is fundamental for laboratory animal technicians, particularly when assessing anatomy and potential injuries or conditions related to the forelimbs of animals.

Other answers refer to bones associated with the hindlimb or other parts of the skeleton. For instance, the tibia and fibula are bones of the lower leg in the hindlimb, while the femur and tarsals are associated with the upper and lower regions of the hindlimb respectively. The patella is a small bone located in
