Study Notes
Central Nervous System (CNS)
- The CNS is vital for processing information
- Consists of two main parts: the brain and spinal cord
- The brain is the control center for processing sensory information, regulating bodily functions, and cognitive processes
- The spinal cord acts as a communication highway between the brain and the periphery
- It relays messages between the brain and peripheral nervous system and plays a role in reflexes
Peripheral Nervous System
- The peripheral nervous system receives and transmits information from the senses or muscles
- Has sensory nerves for sensation and motor nerves for muscle contractions
- Spinal nerves and cranial nerves deliver information
Autonomic Nervous System
- Largely unconscious control of bodily functions
- Includes breathing, pupil dilation, sexual arousal, and digestion
- Composed of two parts: sympathetic (fight or flight) and parasympathetic (rest and digest)
Neuron
- The fundamental unit of the nervous system
- Consists of:
- Cell body (responsible for cell maintenance)
- Axon (covered by myelin to transmit electrical impulses)
- Dendrite (receive signals from other cells)
- Many types of neurons perform specialised tasks
Communication
- The electrical signal in neurons is called an action potential
Synapse
- The junction between neurons
- Neurotransmitters are released from the axon terminal to communicate with the receiving neuron
- Receptors are activated by specific neurotransmitters
