Study Notes

Nervous System Structure

The three main parts of the nervous system are the Central Nervous System (CNS), Peripheral Nervous System (PNS), and Autonomic Nervous System (ANS).
The Central Nervous System (CNS) consists of the brain and spinal cord.

Functions of Glial Cells

Astrocytes provide nutrients and oxygen to neurons, and remove waste products.
Oligodendrocytes produce the myelin sheath that insulates and protects axons in the CNS.
Microglia act as the immune system of the CNS, protecting it from infection and disease.

Nervous System Subsystems

The Somatic Nervous System controls voluntary movements, transmitting signals from the CNS to muscles and glands.
The Autonomic Nervous System (ANS) regulates involuntary actions, such as heart rate, blood pressure, and digestion.
The Autonomic Nervous System has two subsystems: the Sympathetic Nervous System and the Parasympathetic Nervous System.

Functions of Nerve Cells

Schwann cells produce the myelin sheath that insulates and protects axons in the PNS.

Autonomic Nervous System Functions

The Sympathetic Nervous System stimulates the "fight or flight" response, increasing heart rate and energy levels.
The Parasympathetic Nervous System promotes relaxation and reduces energy levels.
