1What is the main function of the cranium in the human skeletal system?

A.To produce red blood cells

B.To protect the brain from injury

C.To assist in the breathing process

D.To store excess calcium and phosphorus

Explanation: The cranium (skull) is a hard bone structure that surrounds and protects the brain from physical injury. While bone marrow inside long bones produces blood cells, and bones do store minerals, the specific function of the cranium is protection.

2Which bone is the longest and strongest bone in the human body?

A.Femur

B.Humerus

C.Tibia

D.Fibula

Explanation: The femur, also known as the thigh bone, is the longest, heaviest, and strongest bone in the human body. It supports the weight of the upper body and is essential for movement.

3What type of joint is found in the human shoulder and hip, allowing for the widest range of movement?

A.Hinge joint

B.Pivot joint

C.Ball-and-socket joint

D.Gliding joint

Explanation: The ball-and-socket joint allows for multi-directional movement and rotation. In this joint, the rounded head of one bone fits into the cup-like cavity of another, as seen in the shoulder and hip.

4Which of the following connects bones to other bones at a joint?

A.Tendons

B.Ligaments

C.Cartilage

D.Synovial fluid

Explanation: Ligaments are tough bands of fibrous connective tissue that connect bone to bone, helping to stabilize joints and hold bones in place.

5Which component of bone tissue is responsible for the production of white blood cells, red blood cells, and platelets?

A.Yellow bone marrow

B.Red bone marrow

C.Periosteum

D.Compact bone

Explanation: Red bone marrow is the site of hematopoiesis, where stem cells divide to produce red blood cells, white blood cells, and platelets. It is found in the spongy ends of long bones and in flat bones like the pelvis and ribs.

6Which type of muscle tissue is found in the walls of internal organs, such as the stomach and intestines?

A.Skeletal muscle

B.Smooth muscle

C.Cardiac muscle

D.Voluntary muscle

Explanation: Smooth muscle is involuntary muscle tissue that is located in the walls of hollow internal organs. It works automatically to move substances through the body, such as food through the digestive tract.

7When you bend your elbow to lift an object, what actions do the biceps and triceps muscles perform?

A.The biceps contracts and the triceps contracts

B.The biceps relaxes and the triceps contracts

C.The biceps contracts and the triceps relaxes

D.The biceps relaxes and the triceps relaxes

Explanation: Muscles work in antagonistic pairs because they can only pull, not push. When bending the arm, the biceps (flexor) contracts to pull the forearm up, while the triceps (extensor) relaxes.

8What is the main role of calcium ions in muscle contraction?

A.They bind to regulatory proteins to expose binding sites on actin filaments

B.They provide the direct energy needed for filaments to slide

C.They break down lactic acid built up during muscle fatigue

D.They transmit electrical impulses along motor neurones

Explanation: During muscle contraction, calcium ions are released from the sarcoplasmic reticulum and bind to troponin. This causes a shape change that shifts tropomyosin, exposing the myosin-binding sites on the actin filaments so contraction can occur.

9Which layer of the skin contains blood vessels, sweat glands, and hair follicles?

A.Epidermis

B.Dermis

C.Subcutaneous layer

D.Melanin

Explanation: The dermis is the thick inner layer of skin beneath the epidermis. It contains blood vessels, sensory receptors, hair follicles, sweat glands, and oil glands.

10How does the skin help lower the body temperature on a hot day in the Bahamas?

A.By constricting blood vessels and shivering

B.By dilating blood vessels and releasing sweat

C.By producing more melanin to block the sun

D.By goosebumps raising the hairs to trap air

Explanation: To cool the body down, blood vessels in the dermis dilate (vasodilation) to bring warm blood closer to the surface to radiate heat away. At the same time, sweat glands release sweat, which absorbs body heat and cools the skin as it evaporates.

About the BJC Health Science Exam

The Bahamas Junior Certificate (BJC) Health Science examination is a national academic assessment administered at the end of Grade 9. The exam measures students' understanding of essential health concepts, human anatomy, physiology, nutrition, hygiene, disease prevention, safety, and mental health. Candidates sit for two papers: Paper 1, a 1-hour multiple-choice exam with 40 questions, and Paper 2, a 1.5-hour structured and short-answer exam. This practice bank is designed to prepare students for the multiple-choice section of the assessment.

BJC Health Science Study Tips from Top Performers

1Memorize the names and functions of major bones in the skeleton, types of muscles, and layers of the skin.

2Understand the functions and organs of the major body systems: digestive, circulatory, respiratory, and excretory.

3Learn the seven classes of nutrients, their primary food sources, and the deficiency diseases associated with each (e.g., scurvy, rickets, beriberi).

4Differentiate between infectious (pathogen-caused) and non-communicable (lifestyle/genetic) diseases, citing examples for each.

5Study basic first aid protocols for common situations like minor burns, cuts, insect bites, nosebleeds, and choking (Heimlich maneuver).
