Observation
Most of the candidates avoided this question and the performance of those that attempted the question was poor. In part (a) many candidates could not name the part of the body where the listed muscles are located in human body, some just wrote any parts of the body. In part (b) few candidates that attempted this question had no knowledge of muscles’ movements in human.
The expected answers are as follow:
7. (a) LOCATIONS OF MUSCLES IN THE BODY
(I) biceps - anterior of humerus / upper arm
(ii) pectoralis - anterior part of the chest breast
(iii) gastrocnemius - posterior part of the lower leg
(iv) deltoid - shoulder
(v) triceps - posterior part of the humerus / upper arm
(vi) quadriceps - anterior part of thigh
(b) MAJOR MUSCLES INVOLVED IN MOVEMENTS
(i) flexion of the forearm - biceps/triceps
(ii) flexion of the knee - hamstrings/quadriceps
(iii) extension of the forearm - triceps/biceps
