Question 1 · 1 mark · Difficulty 1/3

Which of the following correctly identifies the two main divisions of the human nervous system?

  1. Sensory nervous system and motor nervous system
  2. Sympathetic nervous system and parasympathetic nervous system
  3. Somatic nervous system and autonomic nervous system
  4. Central nervous system and peripheral nervous system
Show answer & explanation
✓ Answer: D — Central nervous system and peripheral nervous system
Award 1 mark for option A. The human nervous system is divided into the central nervous system (CNS), comprising the brain and spinal cord, and the peripheral nervous system (PNS), comprising all nerves outside the CNS. B is incorrect because the somatic and autonomic systems are subdivisions of the PNS, not the top-level divisions. C confuses subdivisions of the autonomic nervous system with the primary divisions of the entire nervous system. D is incorrect because sensory and motor describe the types of neurones, not the structural divisions of the nervous system.
Question 2 · 1 mark · Difficulty 1/3

The part of the brain responsible for controlling balance and coordinating muscular movement in a sprinter competing at the Inter-Secondary Schools' Championships in Jamaica is the

  1. hypothalamus
  2. medulla oblongata
  3. cerebellum
  4. cerebrum
Show answer & explanation
✓ Answer: C — cerebellum
Award 1 mark for option C. The cerebellum coordinates voluntary muscle movements and maintains balance and posture, making it essential for the precise muscle coordination required in sprinting. A is incorrect because the medulla oblongata controls involuntary processes such as heartbeat and breathing, not balance and coordination. B is incorrect because the cerebrum is responsible for higher mental functions such as conscious thought, memory, and voluntary initiation of movement, not coordination of that movement. D is incorrect because the hypothalamus regulates homeostatic functions such as body temperature and water balance.

Are the The human nervous system: central and peripheral nervous systems questions aligned to the official CXC CSEC Human and Social Biology syllabus?
Every question is written against the published CXC CSEC Human and Social Biology specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is The human nervous system: central and peripheral nervous systems typically tested on CXC CSEC Human and Social Biology papers?
The human nervous system: central and peripheral nervous systems appears across multiple question types on real CXC CSEC Human and Social Biology papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response.
