What to Focus On
- Neurons are the structural and functional units of the nervous system.
- CNS = Brain + Spinal Cord; PNS = Nerves outside CNS.
- Afferent nerves carry sensory signals; efferent nerves carry motor signals.
- Brain has three parts: forebrain, midbrain, hindbrain.
- Cerebrum controls thinking and voluntary actions.
- Hypothalamus regulates body temperature, hunger, thirst.
- Neuron parts: cell body, dendrites, axon.
- Resting potential: inner side negative; outer side positive.
- Action potential: reversal of charge due to Na+ entry.
Common Mistakes to Avoid
The cerebrum is only responsible for thinking and memory, not for movement.
All neurons have the same structure — a cell body with two long fibers.
The spinal cord only transmits signals and does not process any information.
Memory Tips
Three parts of the brain: Forebrain, Midbrain, Hindbrain
Functions of the Cerebrum: Sensory, Motor, Association areas
Parts of the Diencephalon: Thalamus, Hypothalamus, Epithalamus
Cerebellum = 'Little Brain' and its function in coordination
