Question 1: Which part of the brain controls balance, coordination, and fine motor movements?
- Cerebrum
- Cerebellum (Correct answer)
- Brainstem
- Thalamus
Correct answer: Cerebellum
The cerebellum, located at the back of the brain, coordinates voluntary movements and maintains balance and posture.
Question 2: The femur articulates proximally with which bone to form the hip joint?
- Tibia
- Ilium
- Acetabulum of the pelvis (Correct answer)
- Sacrum
Correct answer: Acetabulum of the pelvis
The head of the femur fits into the acetabulum, the cup-shaped socket on the lateral pelvis, forming the hip joint.
Question 3: Which blood vessel carries deoxygenated blood from the right ventricle to the lungs?
- Pulmonary vein
- Aorta
- Pulmonary artery (Correct answer)
- Superior vena cava
Correct answer: Pulmonary artery
The pulmonary artery is the only artery that carries deoxygenated blood, transporting it from the right ventricle to the lungs.
Question 4: What is the term for the tissue that lines the inner surface of blood vessels?
- Epithelium
- Endothelium (Correct answer)
- Mesothelium
- Periosteum
Correct answer: Endothelium
Endothelium is the specialized simple squamous epithelium that lines the interior of blood and lymphatic vessels.
Question 5: In which organ does the majority of chemical digestion and nutrient absorption occur?
- Stomach
- Large intestine
- Small intestine (Correct answer)
- Duodenum only
Correct answer: Small intestine
The small intestine is the primary site of both chemical digestion and absorption of nutrients into the bloodstream.
Question 6: Which cranial nerve is responsible for the sense of smell?
- Cranial nerve I (Olfactory) (Correct answer)
- Cranial nerve II (Optic)
- Cranial nerve V (Trigeminal)
- Cranial nerve VII (Facial)
Correct answer: Cranial nerve I (Olfactory)
The olfactory nerve (CN I) transmits smell signals from the nasal epithelium to the olfactory bulb in the brain.
Question 7: The axial skeleton includes which of the following structures?
- Femur and tibia
- Humerus and radius
- Skull, vertebral column, and rib cage (Correct answer)
- Clavicle and scapula
Correct answer: Skull, vertebral column, and rib cage
The axial skeleton forms the central axis of the body and includes the skull, vertebral column, sternum, and ribs.
