Key Topics to Revise
1
Evolutionary Nature of Human Behaviour
- Humans evolved from earlier species through natural selection over millions of years.
- Key evolutionary changes in humans: larger brain, bipedalism (walking on two legs), and opposable thumb for tool use.
- Evolution favours traits that improve survival and reproduction — this is called 'fitness'.
2
Structure and Function of the Nervous System
- The nervous system controls all body functions through neurons that transmit signals.
- It has two main parts: Central Nervous System (CNS) and Peripheral Nervous System (PNS).
- CNS includes brain and spinal cord; PNS connects CNS to body parts.
3
Brain Structure and Functions
- Brain is divided into hindbrain, midbrain, and forebrain.
- Hindbrain: controls basic life functions — medulla (breathing, heartbeat), pons (sleep, hearing), cerebellum (balance, coordination).
- Midbrain: connects hindbrain and forebrain; contains Reticular Activating System (RAS) for alertness.
4
Endocrine System and Hormones
- Endocrine system consists of ductless glands that secrete hormones directly into blood.
- Hormones regulate growth, metabolism, reproduction, and emotions.
- Pituitary gland is the 'master gland' — controls other endocrine glands.
