Anatomy/Kinesiology MCQ - Practice Questions with Answers

Extension is the joint movement in which the angle between the bones increases and the limb straightens. Flexion is the opposite movement because it decreases that angle. Therefore the movement described in the question is extension, so D is correct.

The correct answer is A because arthrology is the branch of anatomy that studies joints. Nephrology deals with kidneys and cardiology deals with the heart, so they do not match the question.

The correct answer is B because myopathy means a disease or disorder of muscles. Myology is the study of muscles, while psychology and astrology are unrelated to muscular disease.

The correct answer is D because a spinograph is used to assess spinal curvature, especially the lateral curvature seen in scoliosis. Kyphosis and lordosis are abnormal forward-backward spinal curvatures, while knock knee is a lower-limb deformity.

Voluntary muscles are skeletal muscles, and they make up about 40 percent of human body weight in standard anatomy descriptions. Therefore option A is the expected value for this exam-level fact.
