A) wrist
B) thigh
C) diaphragm
D) humerus
Correct Answer: A
Solution :
Pulse is a series of waves of dilation that pass along the arteries, caused by pressure of blood pumped from the heart through contractions of the left ventricles. In humans, it can be felt easily where arteries pass close to the skin surface like at the wrist. Diaphragm is the muscular membrane that separates the thorax (chest) from the abdomen in mammals. It plays an essential role in breathing being depressed during inspiration and raised during expiration. Humerus is the long bone of upper arm of tetrapod vertebrates. It articulates with the scapula at the glenoid cavity and with the ulna and radius at the elbow.
