The Nervous System Nervous System: Consists of all the nerve cells. **It is the body’s speedy, electrochemical communication system. Central Nervous System (CNS): the brain and spinal cord. Peripheral Nervous System (PNS): the sensory and motor neurons that connect the central nervous system (CNS) to the rest of the body.

The central nervous system Brain Spinal cord A collection of neurons and supportive tissue running from the base of the brain down the center of the back Protected by spinal column 4

Central Nervous System – The Spinal Cord and Reflexes

Organization of the nervous system
Slide 9-

The Nerves Nerves consist of neural “cables” containing many axons. They are part of the peripheral nervous system and connect muscles, glands, and sense organs to the central nervous system.
Slide 10-

Divisions of the Peripheral Nervous System There are two divisions of the peripheral nervous system: the somatic, or voluntary portion the autonomic, or involuntary portion Somatic Nervous System: The division of the peripheral nervous system that controls the body’s skeletal muscles (voluntary). Autonomic Nervous System: Part of the PNS that controls the glands and other muscles (involuntary).

Organization of the nervous system
Slide 12-

The autonomic portion of the peripheral nervous system governs involuntary, visceral functions…such as heart and breathing rate, blood pressure, etc. It is divided into two systems: Sympathetic Nervous System: Division of the ANS that arouses the body, mobilizing its energy in stressful situations. Parasympathetic Nervous System: Division of the ANS that calms the body, conserving its energy. Autonomic Nervous System (ANS)

Organization of the nervous system
Slide 14-

The Sympathetic Nervous System Mobilizes the body’s resources for emergencies and creates the fight-or-flight response. “Arouses”
Slide 15-

Organization of the nervous system
Slide 16-

The Parasympathetic Nervous System Activates processes that conserve bodily resources… slowing heart rate, reducing blood pressure, etc. “Calms” (rest and digest)

See “Fight or Flight” in action in this short cartoon: http://cmhc.utexas.edu/stressrecess/Level_One/fof.html
Slide 19-

Review In everyday situations the sympathetic and parasympathetic nervous system work together to keep you in a steady internal rate. What happens if these are out of wack? .

Journal How does information flow through your nervous system as you pick up a fork? Summarize this process.
