Science Content Standards: Note the following are examples.


9. As a result of the coordinated structures and functions of organ systems, the internal environment of the human body remains relatively stable (homeostatic), despite changes in the outside environment.
As a basis for understanding this concept, students know: 

b. how the nervous system mediates communication between different parts of the body and interactions with the 
c. how feedback loops in the nervous and endocrine systems regulate conditions within the body. 
d. the functions of the nervous system, and the role of neurons in transmitting electrochemical impulses. 
e. the roles of sensory neurons, interneurons, and motor neurons in sensation, thought, and response.

      The human nervous system is divided into the central nervous system (CNS), consisting of the brain and spinal cord, 
and the peripheral nervous system (PNS), everything outside the central nervous system.
      The peripheral nervous system is divided into 2 divisions: sensory division (afferent) and motor division (efferent). 
The sensory division transmits impulses from the sense organs (receptors) to the CNS.  The motor division transmits 
impulses from the CNS to muscles and glands (effectors).  The motor division has 2 subdivisions, the somatic nervous
system, under conscious control or voluntary, and autonomic nervous system, controlling involuntary functions t
hroughout the body.  The peripheral nervous system is composed of the spinal and cranial nerves.  The spinal nerves
carry impulses to and from the spinal cord.  The cranial nerves carry impulses to and from the brain.  These spinal and 
cranial nerves nerves are a communication link all parts of the body.

Students need a basic background in lab procedures, cooperative team (timekeeper, supplies, clean-up) and a basic 
understanding of the nervous system.
