Nervous System Concept Map
The nervous system contains many divisions, all of which sustain differing functions. This activity will help you understand the many aspects and roles of the nervous system.
After learning about the nervous system and its variety of subdivisions, create a concept map as an overview of the system. A list of terms that must be incorporated into the assignment is provided below, but feel free to add terms as needed. You will be required to write the relationship that exists between the two concepts that you linked together in words on the connecting lines. A single concept can have many other concepts linked to it. Be sure to write down the relationship on the line for full marks.
Terms that must be included are:
Central nervous system
Peripheral nervous system
Autonomic nervous system
Sympathetic nervous system
Parasympathetic nervous system
Cerebrospinal fluid
Meninges
Spinal cord
Spinal nerves
Cranial nerves
Sensory nerves
Motor nerves
Ventricles
Brainstem
Sample Answer
Nervous System Concept Map Outline
Start with the highest-level concept and branch downward, ensuring all required terms (bolded) are used and the relationship is written on the connecting lines.
I. Major Divisions (Root)
Nervous System
$\downarrow$ is divided into
$\rightarrow$ Central nervous system (CNS)
$\rightarrow$ Peripheral nervous system (PNS)
II. Central Nervous System (CNS) Branch
Central nervous system
$\downarrow$ is protected by
$\rightarrow$ Meninges
$\downarrow$ protects and contains
$\rightarrow$ Cerebrospinal fluid (CSF)
$\downarrow$ is housed within cavities called
$\rightarrow$ Ventricles
Central nervous system
$\downarrow$ is composed of
$\rightarrow$ Brainstem
$\rightarrow$ Spinal cord
Brainstem
$\downarrow$ is the origin of many
$\rightarrow$ Cranial nerves (along with the brain)
Spinal cord
$\downarrow$ gives rise to
$\rightarrow$ Spinal nerves
III. Peripheral Nervous System (PNS) Branch
Peripheral nervous system
$\downarrow$ is composed of
$\rightarrow$ Spinal nerves
$\rightarrow$ Cranial nerves
$\rightarrow$ Autonomic nervous system (ANS)
Spinal nerves
$\downarrow$ contain
$\rightarrow$ Sensory nerves (afferent pathway)
$\rightarrow$ Motor nerves (efferent pathway)
Cranial nerves
$\downarrow$ contain
$\rightarrow$ Sensory nerves (some are purely sensory)
$\rightarrow$ Motor nerves (some are purely motor)
IV. Autonomic Nervous System (ANS) Branch
Autonomic nervous system
$\downarrow$ is composed of
$\rightarrow$ Sympathetic nervous system (SNS)
$\rightarrow$ Parasympathetic nervous system (PNS)
Sympathetic nervous system
$\rightarrow$ controls $\leftarrow$ Parasympathetic nervous system
$\downarrow$ (has opposing effects on organs)
Sympathetic nervous system
$\downarrow$ is know
Parasympathetic nervous system
$\downarrow$ is known for
$\rightarrow$ "Rest and digest" functions
Complete List of Connections for Drawing Your Map
Use the connections below to draw the lines and write the relationship text:
Nervous System $\rightarrow$ Central nervous system (is divided into)
Nervous System $\rightarrow$ Peripheral nervous system (is divided into)
Central nervous system $\rightarrow$ Meninges (is protected by)
Meninges $\rightarrow$ Cerebrospinal fluid (contains and surrounds)
Central nervous system $\rightarrow$ Ventricles (contains fluid-filled cavities called)
Ventricles $\rightarrow$ Cerebrospinal fluid (produces and contains)
Central nervous system $\rightarrow$ Brainstem (is a major component of)
Central nervous system $\rightarrow$ Spinal cord (is a major component of)
Brainstem $\rightarrow$ Cranial nerves (is the primary origin for many)
