Question 1: Name three functions of the human skeletal system.

Answer: Support for the body, protection of internal organs, movement facilitation, blood cell production, mineral storage.

Question 2: Describe the difference between the axial and appendicular skeletons. Provide two examples of bones from each.

Answer: The axial skeleton includes bones that form the central axis of the body, such as the skull and spine. The appendicular skeleton includes bones of the limbs and girdles, such as the clavicle and femur.

Question 3: Explain the role of the long bones in the human body and give two examples.

Answer: Long bones provide support, leverage, and facilitate movement. Examples include the femur and humerus.

Question 4: Identify and describe the function of the joint that allows the arm to move in a circular motion.

Answer: The ball-and-socket joint, located at the shoulder, allows for circular movement of the arm.

Question 5: Sketch the outline of a human skull and label the following bones: frontal bone, parietal bone, and mandible.

Answer: A correct sketch should outline the shape of a human skull with the three bones clearly labeled and positioned appropriately.

Question 6: Describe the process of bone healing after a fracture.

Answer: Bone healing involves inflammation, formation of a soft callus, replacement with a hard callus, and remodeling of the bone to restore its original shape and strength.

Question 7: Identify two types of joints in the human body and give an example of each.

Answer: Hinge joints, such as the knee, and ball-and-socket joints, such as the shoulder.

Question 8: Discuss how regular weight-bearing exercise can affect the density of bones.

Answer: Weight-bearing exercise stimulates bone formation, increasing bone density and reducing the risk of osteoporosis.

Question 9: Explain the term 'articulation' in relation to the skeletal system.

Answer: Articulation refers to a joint where two or more bones meet, allowing movement or stability.

Question 10: Draw a simple diagram of the human vertebral column. Label the cervical, thoracic, and lumbar regions.

Answer: A correct diagram should show a curved column with three distinct regions labeled appropriately: cervical (neck area), thoracic (upper back), and lumbar (lower back).
