The Nervous System

• (^) The collections of nerve cells and

supporting structures that are distributed

throughout the body.

• (^) The parts include: …

The Nervous System

• (^) Autonomic Nervous System
  • The afferent and efferent nerves that innervate the body organs to coordinate the internal environment (homeostasis)
• (^) Somatic Nervous System
  • The afferent and efferent nerves that innervate the musculoskeletal and integumetary systems for the purposes of motor function and sensation.

The Nervous System

• (^) Enteric Nervous System
  • (^) The network of nerves that innervate the gut and coordinate gut function
• (^) Vascular Nervous System
  • (^) The network of nerves that innervate the blood vessels and coordinate vascular smooth muscle function

The Nerve Cell

Nerve Tissue

Central Nervous System

• (^) There is a tremendous amount of

architecture to the CNS

• (^) We will proceed by layers

from the outside in
