MHACBO QMHP (QUALIFIED MENTAL HEALTH
PROFESSIONAL) EXAMINATION QUESTIONS AND
CORRECT ANSWERS WITH RATIONALES
Section 1: Anatomy & Physiology (Questions 1-60)
1. Which of the following is the primary function of the mitochondria?
A) Protein synthesis
B) Lipid storage
C) ATP production
D) Cell division
Correct Answer: C
Rationale: Mitochondria are known as the "powerhouses" of the cell because
their primary role is to generate adenosine triphosphate (ATP) through cellular
respiration.
2. The sinoatrial (SA) node is located in which chamber of the heart?
A) Left ventricle
B) Right ventricle
C) Left atrium
D) Right atrium
Correct Answer: D
,Rationale: The SA node, the heart's natural pacemaker, is located in the wall of
the right atrium near the opening of the superior vena cava.
3. Which type of joint is characterized by the presence of a synovial cavity?
A) Fibrous joint
B) Cartilaginous joint
C) Synovial joint
D) Amphiarthrosis
Correct Answer: C
Rationale: Synovial joints are distinguished by a synovial cavity filled with synovial
fluid, allowing for free movement. Fibrous and cartilaginous joints lack this cavity.
4. The functional unit of the kidney is the:
A) Nephron
B) Alveolus
C) Neuron
D) Sarcomere
Correct Answer: A
Rationale: The nephron is the microscopic structural and functional unit of the
kidney responsible for filtering blood and forming urine.
5. Which lobe of the brain is primarily responsible for processing visual
information?
A) Frontal lobe
B) Temporal lobe
C) Parietal lobe
,D) Occipital lobe
Correct Answer: D
Rationale: The occipital lobe, located at the back of the brain, is the primary visual
processing center.
6. Which hormone is primarily responsible for regulating blood glucose levels by
lowering them?
A) Glucagon
B) Cortisol
C) Insulin
D) Thyroxine
Correct Answer: C
Rationale: Insulin, secreted by the beta cells of the pancreas, facilitates the
uptake of glucose by cells, thereby lowering blood glucose levels. Glucagon does
the opposite.
7. The smallest blood vessels in the body, where exchange of gases and nutrients
occurs, are called:
A) Arteries
B) Veins
C) Capillaries
D) Venules
Correct Answer: C
Rationale: Capillaries are microscopic vessels with thin walls that allow for the
diffusion of oxygen, carbon dioxide, nutrients, and waste products between blood
and tissues.
, 8. Which type of muscle tissue is involuntary and non-striated?
A) Skeletal muscle
B) Cardiac muscle
C) Smooth muscle
D) Voluntary muscle
Correct Answer: C
Rationale: Smooth muscle is found in the walls of internal organs and is under
involuntary control. It lacks the striations (stripes) seen in skeletal and cardiac
muscle.
9. The process of bone formation is known as:
A) Ossification
B) Resorption
C) Remodeling
D) Calcification
Correct Answer: A
Rationale: Ossification, or osteogenesis, is the process by which new bone tissue
is formed. Resorption is the breakdown of bone.
10. The 'fight or flight' response is triggered by the release of hormones from
which gland?
A) Thyroid gland
B) Pituitary gland
C) Adrenal medulla
D) Pineal gland
