Topics in Coordination and Control
The Human Neural System
- The neural system is made up of specialized cells called neurons that detect, receive, and transmit stimuli.
- It is divided into the Central Nervous System (CNS) and Peripheral Nervous System (PNS).
- CNS includes the brain and spinal cord; it processes information and controls responses.
Central Nervous System (CNS): Brain and Spinal Cord
- Brain is protected by the skull and covered by three meninges: dura mater, arachnoid mater, and pia mater.
- Brain has three main parts: Forebrain, Midbrain, and Hindbrain.
- Forebrain includes cerebrum, thalamus, and hypothalamus. Cerebrum controls thinking, memory, and voluntary actions.
Autonomic Neural System (ANS)
- ANS controls involuntary actions and is divided into sympathetic and parasympathetic systems.
- Sympathetic system prepares the body for 'fight or flight' — increases heart rate, dilates pupils, inhibits digestion.
- Parasympathetic system promotes 'rest and digest' — slows heart rate, constricts pupils, stimulates digestion.
Generation and Conduction of Nerve Impulse
- Neurons are polarized at rest — inside is negative, outside is positive due to ion distribution.
- Resting potential is maintained by Na⁺-K⁺ pump (3 Na⁺ out, 2 K⁺ in).
- When stimulated, Na⁺ channels open, causing depolarization (action potential).
