The central nervous system is made up of
- A. sensory organs and muscles.
- B. the brain and muscles.
- C. the sensory organs and spinal cord.
- D. the brain and spinal column.
Correct Answer: D
Rationale: The correct answer is D: the brain and spinal column. The central nervous system comprises the brain and spinal cord, which are responsible for processing and transmitting information throughout the body. The brain controls cognitive functions and coordinates movement, while the spinal cord serves as a pathway for nerve signals.
Explanation:
1. The brain is the primary organ for processing information and controlling bodily functions.
2. The spinal cord acts as a conduit for nerve signals to travel between the brain and the rest of the body.
3. Together, the brain and spinal cord form the central nervous system, playing a crucial role in overall body function.
Summary of other choices:
A: Sensory organs and muscles do not constitute the central nervous system. Sensory organs detect stimuli, while muscles are part of the peripheral nervous system.
B: The brain and muscles are not the only components of the central nervous system. The spinal cord is also a crucial part.
C: While the sensory organs and spinal cord are components of the nervous system
Pons, cerebellum and medulla are part of which brain?
- A. Forebrain
- B. Midbrain
- C. Hindbrain
- D. None of the above
Correct Answer: C
Rationale: Hindbrain is the correct answer because it consists of the pons, cerebellum, and medulla oblongata. These structures are responsible for coordinating movement, balance, and vital autonomic functions such as breathing and heart rate.

Which drug for epilepsy inhibits both vitamin D and folate metabolism?
- A. valproate
- B. carbamazepine
- C. gabapentin
- D. phenytoin
Correct Answer: D
Rationale: Phenytoin is an antiepileptic drug that can interfere with the metabolism of vitamin D and folate, leading to potential deficiencies. Patients on phenytoin often require supplementation to prevent complications like osteoporosis or anemia.
The resting membrane potential of a cell
- A. is dependent on the permeability of the cell membrane to K+ being greater than the permeability to Na+
- B. falls to zero immediately when Na+, K+ ATPase in the membrane is inhibited
- C. is usually equal to the equilibrium potential for K+
- D. is usually equal to the equilibrium potential for Na+
Correct Answer: A
Rationale: The resting membrane potential is primarily determined by the permeability of the cell membrane to potassium ions (K+), which is greater than its permeability to sodium ions (Na+). This is because the membrane has more leak channels for K+ than for Na+, allowing K+ to diffuse out of the cell, creating a negative intracellular environment. The Na+, K+ ATPase pump maintains this gradient but does not directly set the resting potential. Inhibition of the pump would eventually disrupt the gradient, but the potential does not immediately fall to zero.
