Free Bachelor of Pharmacy (B.Pharm.) Human Anatomy & Physiology Questions and Answers

Question 1

Tetany is a relative of

Accepted Answer

Hypocalcemia

Answer

Tetany is a medical sign characterized by involuntary muscle contractions, cramps, and spasms. It is primarily caused by hypocalcemia, which is an abnormally low level of calcium in the blood. Low extracellular calcium increases the excitability of nerve and muscle cells, leading to spontaneous and sustained muscle contractions.

Question 2

The bone of the upper jaw is

Accepted Answer

Maxilla

Answer

The maxilla is the bone that forms the upper jaw. It is a paired bone that fuses in the midline, housing the upper teeth and contributing to the structure of the face, including the floor of the nasal cavity and the orbits. In contrast, the mandible forms the lower jaw.

Question 3

An example of the shoulder joint is:

Accepted Answer

Ball and socket joint

Answer

The shoulder joint, specifically the glenohumeral joint, is a classic example of a ball and socket joint. This type of synovial joint allows for the greatest range of motion, including flexion, extension, abduction, adduction, circumduction, and rotation. This extensive mobility is due to the spherical head of the humerus fitting into the cup-like glenoid cavity of the scapula.

Question 4

The layer of the endocardium is

Accepted Answer

heart

Answer

The endocardium is the innermost layer of tissue that lines the chambers of the heart and covers the heart valves. It is a thin, smooth membrane that helps to ensure efficient blood flow and prevent clotting within the heart. Therefore, it is an integral part of the heart structure.

Question 5

The backup pacemaker is

Accepted Answer

AV node

Answer

While the sinoatrial (SA) node is the primary pacemaker of the heart, initiating the electrical impulses, the atrioventricular (AV) node serves as a crucial backup pacemaker. If the SA node fails or its impulses are blocked, the AV node can take over to generate electrical impulses, albeit at a slower rate, ensuring the heart continues to beat.
