TAPE SYLLABUS FROM FIRST SEMESTER ON P.1

5. Objective
SWU: the general parts and functions of the nervous system SW: classify the 3 major functions of the nervous system in a tree map

6. The Nervous System 1m47

7. Chapter 10 Nervous System
The nervous system is composed predominantly of neural tissue
Also has…
Blood vessels
Connective tissue

8. Neural Tissue Neural tissue consists of two cell types:
Neurons aka nerve cells: are specialized to react to physical and chemical changes in their surroundings

9. Neural Tissue Neural tissue consists of two cell types:
2. Neuroglial cells: surround, support, and nourish neurons
Cell body

10. Functions of the Nervous System
3 major functions of N.S.:
Sensory
Integrative
Motor

11. Functions of the Nervous System
Sensory receptors: Gather information by detecting changes inside and outside of the body
Outside:
Light
&
Sound
Intensities
Inside:
Temperature
Oxygen Levels
pH Levels

12. Functions of the Nervous System
Integrative: Convert information from sensory receptors into nerve impulses
Create sensations, add to memory, and produce thoughts

13. Motor Functions: Responsive structures called effectors
Muscles
Glands
Draw on Pg. 2

14. Divisions of the Nervous System

15. Divisions of the Nervous System
Central Nervous System (CNS):
The body’s master control
Brain
Brainstem
Spinal cord

16. Divisions of the Nervous System
Peripheral Nervous System (PNS)
The body’s link to the outside world
Nerves

17. Divisions of the P.N.S. Sensory (Afferent) Division: P.N.S. to C.N.S.
The PNS can further be divided:
Sensory (Afferent) Division:
P.N.S. to C.N.S.
Contains receptors

18. Divisions of the P.N.S. Motor (Efferent) Division:
The PNS can further be divided:
Motor (Efferent) Division:
C.N.S. to rest of body
Sends info to effectors

19. Divisions of the P.N.S. The Motor division can further be divided:
Somatic nervous system: Oversees conscious activities
Ex: skeletal muscle contraction
Autonomic nervous system: Controls involuntary actions
Ex: heartbeat and glands
conscious
Involuntary or unconscious

20. Divisions of the P.N.S. The Autonomic division can further be divided:
Sympathetic nervous system: “Fight or Flight”
Parasympathetic nervous system: “Rest and Digest”
conscious
Involuntary or unconscious

21. Divisions of the Nervous System Video (4m38s)
Cut if late start

22. In a nutshell…. The nervous system can: Detect changes in the body
Make decisions based on the info received
Stimulate muscles and/or glands to respond
Counteract changes to maintain homeostasis
