EXPLORING THE BODY SYSTEM BY SYSTEM: NERVOUS SYSTEM:
(page 146-151, 94)
Name: ______________________ 8___
LEARNING OUTCOME #3: INTERPRET THE HEALTHY FUNCTION OF HUMAN BODY SYSTEMS, AND ILLUSTRATE WAYS THE BODY
REACTS TO INTERNAL AND EXTERNAL STIMULI
3a) describe, in general terms, body systems for respiration, circulation, digestion, excretion and sensory awareness
3b) describe in general terms, the role of individual organs and tissues in supporting the healthy functioning of the human body
3c) describe ways in which various types of cells contribute to the healthy functioning of the human body
3d) describe changes in body functions in response to changing conditions
FUNCTION: -_________________ and ___________________ the actions of all organs and
organ systems. To _________, ____________ and ________________ to changes in
external and internal environments. In short: Monitors and responds to stimuli in
the environment.
1. The nervous system is mainly made up of _________________ tissue. These
specialized cells are called __________________________. It’s job is to ___________
and _____________________ messages.
2. The part of the neuron that receives impulses is called the _________________
(highlight it below). The impulse or message is passed to the neighboring
dendrite by the _____________ (highlight it below). The gap between the dendrites
of one neuron and the axon endings of another neuron is called a synapse.
3. The nervous system consists of two main parts.
________________________________________
Consists of the brain and spinal cord
______________________________________
Made up of cranial (head) and spinal
nerves
4. Label and color the diagram using red for
the central system and blue for the
peripheral system.
THE CENTRAL NERVOUS
SYSTEM:
Parts of the brain
-The largest part of the brain is the
___________________ and it controls
_____________________, _____________________
or _________________________________
-the _________________________ part controls
balance, posture and coordination.
-the __________________________ or brain stem
controls digestion, heartbeat and
___________________________________.
5. THE PERIPHERAL NERVOUS SYSTEM: The peripheral nervous system is divided
into two types of neurons.
___________________ neurons
carry information from body to the
central nervous system.
_______________________ neurons
carry information the central nervous
system to the muscles or organs.
7. The peripheral nervous system can be either
a.
___________________nervous system: where you have conscious control over
your responses to stimuli, like _______________________________________________.
b. ____________________nervous system: an unconscious response to stimuli.
Known as an automatic response (you do not think about it) is controlled by
the __________________ nervous system like __________________________________.
8. Explain the reflex response. Why is it important to have?
9. What is a stroke? What causes it? What does it affect?
