Free APMLE General Anatomy Questions and Answers

Question 1

Which type of connective tissue is responsible for connecting muscles to bones?

Accepted Answer

Tendons

Answer

Tendons are strong, fibrous bands of connective tissue primarily composed of collagen. Their crucial role in the musculoskeletal system is to connect muscles to bones. This connection allows the force generated by muscle contraction to be transmitted to the skeleton, thereby producing movement at the joints.

Question 2

Which part of the skeletal system contains the most bones?

Accepted Answer

Appendicular skeleton

Answer

The appendicular skeleton consists of the bones of the limbs (arms and legs), as well as the pectoral (shoulder) and pelvic girdles that attach them to the axial skeleton. With 126 bones, it contains more bones than the axial skeleton (80 bones), which includes the skull, vertebral column, and rib cage.

Question 3

What type of joint is found between the tibia and fibula at their distal ends?

Accepted Answer

Syndesmosis

Answer

A syndesmosis is a type of fibrous joint where two bones are joined by a ligament or an interosseous membrane, allowing for very limited movement. The distal tibiofibular joint, where the tibia and fibula are connected by the interosseous membrane and ligaments, is a classic example of a syndesmosis, providing stability to the ankle.

Question 4

Which muscle is primarily responsible for plantar flexion of the foot?

Accepted Answer

Gastrocnemius

Answer

The gastrocnemius is a powerful superficial muscle located in the posterior compartment of the lower leg, forming part of the calf. Its primary action is plantar flexion of the foot at the ankle joint. This movement is essential for activities such as walking, running, and jumping, contributing significantly to propulsion.

Question 5

Which artery supplies blood to the plantar surface of the foot?

Accepted Answer

Posterior tibial artery

Answer

The posterior tibial artery is a major artery in the lower leg that descends behind the tibia. It gives off branches that supply the posterior compartment of the leg and then continues into the foot. Here, it branches into the medial and lateral plantar arteries, which are the main blood supply to the plantar (sole) surface of the foot.
