Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Neuron: Structure and Types, 2. Nerve Impulse and Synapse, 3. Nerves, Ganglia, and Divisions of the Nervous System.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 45 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Nervous System after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Neuron is the basic structural and functional unit of the nervous system.
  • Neuron parts are soma, dendrites, axon and axon terminals.
  • Soma is also called cyton or cell body.
  • Myelinated and non-myelinated neurons are classified on the basis of myelin sheath.
  • Sensory neurons carry impulses to the CNS.
  • Motor neurons carry impulses from the CNS to effectors.
  • Nerve impulse is the message transmitted by the axon.
  • Impulse conduction is an electrical phenomenon.
  • Polarization is the resting state of the axon membrane.

Common Mistakes to Avoid

The myelin sheath is part of the neuron.

Ganglia are found inside the central nervous system and contain whole neurons including axons and dendrites.

All nerves are the same, so sensory nerves, motor nerves, and mixed nerves can be used interchangeably.

Memory Tips

Neuron as the basic unit of the nervous system

Parts of a neuron: soma, dendrites, axon, axon terminals

Soma or cyton as the star-shaped cell body with nucleus and Nissl's granules

Dendrites receive impulses
