Sample CIDESCO Theory Practice Questions

Try these sample questions to review concepts for the CIDESCO Theory exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 132+ question experience with AI tutoring.

1Which bone forms the back and lower base of the skull?

A.Frontal bone

B.Occipital bone

C.Temporal bone

D.Sphenoid bone

Explanation: The occipital bone forms the posterior (back) part of the skull and the base of the cranium. It contains the foramen magnum, which allows the spinal cord to pass through and connect with the brain. The frontal bone forms the forehead, while temporal bones form the sides.

2What muscle is responsible for raising the eyebrows and wrinkling the forehead?

A.Frontalis

B.Orbicularis oculi

C.Corrugator supercilii

D.Procerus

Explanation: The frontalis muscle is the anterior portion of the epicranius (occipitofrontalis) muscle. It covers the forehead and is responsible for raising the eyebrows and drawing the scalp forward, causing horizontal wrinkles in the forehead. Orbicularis oculi closes the eye, and corrugator pulls the eyebrows inward.

3What is the primary function of erythrocytes in the human body?

A.To fight infections and foreign pathogens

B.To transport respiratory gases, especially oxygen

C.To assist in blood clotting and coagulation

D.To produce blood plasma proteins

Explanation: Erythrocytes (red blood cells) use hemoglobin primarily to carry oxygen from the lungs to tissues. They also help return carbon dioxide to the lungs, although most carbon dioxide travels in plasma as bicarbonate. Leukocytes fight infection, and platelets support clotting.

4What is the primary function of lymph nodes within the lymphatic system?

A.To pump lymph fluid back to the heart

B.To filter lymph fluid and trap pathogens, foreign substances, and cellular waste

C.To produce red blood cells and platelets

D.To secrete digestive enzymes and hormones

Explanation: Lymph nodes act as specialized filters located along the lymphatic vessels. They contain immune cells (lymphocytes and macrophages) that identify and destroy bacteria, viruses, and cellular debris in the lymph fluid before returning it to the bloodstream. The lymphatic system lacks a pump and relies on muscle movement.

5Which type of nerves carry impulses from the brain and spinal cord to the muscles, causing movement?

A.Sensory (afferent) nerves

B.Motor (efferent) nerves

C.Secretory nerves

D.Reflex nerves

Explanation: Motor (efferent) nerves transmit electrical signals away from the central nervous system (brain and spinal cord) to muscles, glands, and organs, stimulating movement or secretion. Sensory (afferent) nerves carry sensory information from the skin and organs back to the brain.

6Which gland is commonly referred to as the 'master gland' of the endocrine system?

A.Adrenal gland

B.Pituitary gland

C.Thyroid gland

D.Pancreas

Explanation: The pituitary gland is located at the base of the brain and is called the master gland because it secretes hormones that control and regulate the activity of several other endocrine glands, including the thyroid, adrenals, and reproductive glands. It is itself regulated by the hypothalamus.

7What action does the diaphragm perform during inhalation?

A.It contracts and moves downward, expanding the thoracic cavity

B.It relaxes and domes upward, reducing the lung volume

C.It contracts and moves upward to push air out

D.It remains stationary while the ribs expand

Explanation: During inhalation (breathing in), the diaphragm contracts and flattens, moving downward. This movement increases the vertical dimension of the thoracic cavity, lowering intrapleural pressure and allowing the lungs to fill with air. During exhalation, the diaphragm relaxes and rises.

8In which part of the digestive tract does the majority of chemical digestion and nutrient absorption occur?

A.Stomach

B.Small intestine

C.Large intestine

D.Esophagus

Explanation: The small intestine (consisting of the duodenum, jejunum, and ileum) is the primary site for both the chemical breakdown of food (with the help of pancreatic enzymes and bile) and the absorption of nutrients through its villi and microvilli. The stomach primarily performs mechanical churning and acid digestion of proteins.

9What is the functional unit of the kidney responsible for filtering blood and forming urine?

A.Nephron

B.Glomerulus

C.Ureter

D.Renal pelvis

Explanation: The nephron is the microscopic functional unit of the kidney. Each kidney contains approximately one million nephrons, which filter blood, reabsorb essential water and solutes, and secrete waste products to form urine. The glomerulus is just a part of the nephron's filtration system.

10How many cervical vertebrae are found in the human vertebral column?

A.5 cervical vertebrae

B.7 cervical vertebrae

C.12 cervical vertebrae

D.5 fused vertebrae

Explanation: The human vertebral column contains 7 cervical vertebrae in the neck (designated C1 to C7), followed by 12 thoracic vertebrae in the upper back, and 5 lumbar vertebrae in the lower back. The first cervical vertebra (C1) is the atlas, and the second (C2) is the axis.

CIDESCO Theory: Suggested Study Strategy

1Cover all six theory areas because CIDESCO publishes no topic weights.

2Master the specific contraindications for each electrotherapy machine (e.g., galvanic, high frequency, vacuum suction).

3Memorize key chemical terms and the pH scale as it relates to different skin layers and cosmetic products.

4Review standard sanitation and sterilization protocols (autoclaving, chemical disinfection, sanitation levels).

5Use school-supplied timing because CIDESCO publishes no written time limit.
