Human Anatomy and Joint Mechanics Quiz

The collarbone is commonly known as the clavicle and is a long, slender bone that connects the sternum to the shoulder.

The shoulder joint allows for the greatest range of motion in the human body, enabling various movements like flexion, extension, abduction, and rotation.

The shinbone is anatomically known as the tibia, forming the larger and more medial bone of the lower leg.

Skeletal muscle is under voluntary control, allowing conscious control over body movements.

The frontal bone forms the forehead region of the skull, contributing to the protection of the frontal lobe of the brain.

The elbow joint is a hinge joint, allowing movement primarily in flexion and extension.

The anterior talofibular ligament (ATFL) is commonly injured in a sprained ankle, contributing to stability in the lateral aspect of the ankle joint.

The elbow joint is formed by the articulation of the humerus, radius, and ulna, facilitating flexion and extension of the forearm.

A fibrous joint is not a type of synovial joint; it lacks a synovial cavity and is held together by fibrous connective tissue.

The anterior cruciate ligament (ACL) connects the femur to the tibia and plays a crucial role in stabilizing the knee joint, preventing hyperextension.

The quadriceps femoris muscle is primarily responsible for extending the knee joint, straightening the leg.

The biceps brachii muscle is primarily responsible for flexing the forearm at the elbow joint.

The tibialis anterior muscle is involved in the movement of dorsiflexion of the foot, lifting the foot and toes toward the shin.

The adductor magnus muscle is primarily responsible for adduction of the thigh, bringing the leg closer to the midline of the body.

The deltoid muscle is primarily responsible for the movement of abduction of the arm, lifting the arm away from the body.
