Study Notes
Nervous System
- The nervous system is composed of the central nervous system (CNS) and the peripheral nervous system (PNS).
- The CNS is responsible for directing and controlling body functions.
Central Nervous System (CNS)
- Encompasses the brain and spinal cord.
- Brain: Protected by the skull.
- Includes the cerebrum, cerebellum, medulla oblongata, hypothalamus, thalamus, and limbic system.
- Spinal cord: Protected by the vertebral column.
Peripheral Nervous System (PNS)
- Allows communication between the external and internal environments and the CNS.
- Composed of nerves and ganglia.
Cell Types
- Neurons: Generate and transmit impulses.
- Glia: Non-excitable cells supporting and protecting neurons.
- Include astrocytes, satellite cells, ependymal cells, oligodendrocytes, Schwann cells, microglia.
Divisions of the Peripheral Nervous System
- Somatic nervous system: Responsible for voluntary responses.
- Autonomic nervous system: Responsible for involuntary responses.
- Sympathetic nervous system: Triggers responses to stressful situations.
- Parasympathetic nervous system: Regulates the body during relaxation and digestion.
