Question 1 · 1 mark · Difficulty 1/3

A student in Trinidad observed a motorcyclist quickly withdraw his hand after touching a hot exhaust pipe. Which type of neurone carries the impulse FROM the spinal cord to the hand muscles during this reflex action?

  1. Sensory neurone
  2. Motor neurone
  3. Relay neurone
  4. Intermediate neurone
Show answer & explanation
✓ Answer: BMotor neurone
Award 1 mark for identifying motor neurone as carrying impulses away from CNS to effectors (muscles). A is incorrect — sensory neurones carry impulses TO the CNS. C is incorrect — relay neurones are found within the CNS connecting sensory to motor neurones. D is incorrect — intermediate neurone is not standard terminology for this pathway.
Question 2 · 1 mark · Difficulty 2/3

Which structural feature is present in a motor neurone but NOT in a sensory neurone?

  1. Cell body located within the central nervous system
  2. Axon covered by myelin sheath
  3. Dendrites that receive impulses
  4. Nodes of Ranvier along the axon
Show answer & explanation
✓ Answer: ACell body located within the central nervous system
Award 1 mark for identifying this distinguishing feature. Motor neurone cell bodies are located in the CNS (brain or spinal cord), while sensory neurone cell bodies are located in ganglia just outside the CNS. B is incorrect — both neurone types can have myelin sheaths. C is incorrect — both have dendrites. D is incorrect — nodes of Ranvier are present in both myelinated neurone types.

CXC CSEC Biology: Neurones – Structure and Function FAQ

How many CXC CSEC Biology questions on Neurones – Structure and Function are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Neurones – Structure and Function for CXC CSEC Biology, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CXC paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CXC CSEC students preparing for Biology?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Neurones – Structure and Function practice with other Biology topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Neurones – Structure and Function questions aligned to the official CXC CSEC Biology syllabus?
Every question is written against the published CXC CSEC 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 Neurones – Structure and Function typically tested on CXC CSEC Biology papers?
Neurones – Structure and Function appears across multiple question types on real CXC CSEC 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. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
