About Chapter – Neural Control and Coordination
This chapter explains how the nervous system receives, processes and responds to various stimuli. It covers the structure of neurons, nerve impulse transmission, the human brain, spinal cord and sensory organs.
Important concepts covered:
🔹 Nervous system organization
🔹 Neuron structure and types
🔹 Nerve impulse generation and conduction
🔹 Synaptic transmission
🔹 Central nervous system
🔹 Brain and its parts
🔹 Spinal cord
🔹 Reflex action and reflex arc
🔹 Eye structure and vision
🔹 Ear structure and hearing
Important scientists:
🔬 Santiago Ramón y Cajal – Father of Modern Neuroscience
🔬 Camillo Golgi – Golgi staining technique
🔬 Sir Charles Sherrington – Reflex action studies
Important examples:
✔ Neuron
✔ Myelin sheath
✔ Synapse
✔ Cerebrum
✔ Cerebellum
✔ Medulla oblongata
✔ Retina
✔ Cochlea
This chapter is highly important because NEET frequently asks questions from neuron structure, brain functions, reflex arc and sensory organs.
🔥 NEET 2027 Importance of This Chapter
Neural Control and Coordination is one of the highest-scoring Human Physiology chapters.

✅ Answer Key + Detailed Solutions
1. Answer: B – Neuron
Explanation: The neuron is the structural and functional unit of the nervous system.
2. Answer: B – Schwann cells
Explanation: Schwann cells produce the myelin sheath around peripheral nerve fibres.
3. Answer: B – Cerebellum
Explanation: The cerebellum coordinates muscular activity and maintains posture and balance.
4. Answer: B – Nodes of Ranvier
Explanation: Saltatory conduction occurs by jumping from one Node of Ranvier to the next.
5. Answer: C – Rods and Cones
Explanation: The retina contains rods for dim-light vision and cones for colour vision.
6. Answer: B – Acetylcholine
Explanation: Acetylcholine is a common neurotransmitter involved in nerve impulse transmission.
7. Answer: B – Cochlea
Explanation: The cochlea converts sound vibrations into nerve impulses.
8. Answer: C – Spinal cord
Explanation: Reflex actions are rapid involuntary responses coordinated mainly by the spinal cord.
9. Answer: C – Meninges
Explanation: The meninges are protective membranes surrounding the brain and spinal cord.
10. Answer: C – Optic nerve leaves the retina
Explanation: The blind spot lacks photoreceptors because it is the point where the optic nerve exits the eye.
