What are the three steps of the nervous system? Ans✓✓✓1. Sensory
input
2. Integration
3. Motor output
What is sensory input? Ans✓✓✓Sensory input from the environment is
detected by sensory nerves and travels through the body to communicate
with other nerve cells
What is integration? Ans✓✓✓Processing and interpretation of sensory
input
What is motor output? Ans✓✓✓a response to integrated stimuli; the
response activates muscles or glands by sending motor output through
motor nerves
What are the two principal subdivisions of the nervous system?
Ans✓✓✓Central
Peripheral
What is the function of the CNS? Ans✓✓✓»Where all signals come to
and from
,»Where they are integrated
»Where information can be stored
What is the function of the PNS? Ans✓✓✓System that brings those
signals to and from the CNS
What are the two divisions that the PNS can be further broken down
into? Ans✓✓✓Sensory (afferent) division
Motor (efferent) division
What does the sensory division do? Ans✓✓✓Relays information to
CNS
Sensing things such as sight, smell, touch and even pain
Sends the information to the CNS through sensory neurons
What does the motor division do? Ans✓✓✓Relays information from
CNS to target cells
The actual response that is elicited
Signal comes from the CNS, the brain, or spinal cord and is relayed to a
target cell through efferent neurons
What subdivisions can the motor (efferent) division be further divided
into? Ans✓✓✓Somatic
Autonomic
, What is the function of the somatic nervous system? And how does it do
that? Ans✓✓✓Controls voluntary movement
Signal comes from the CNS through the efferent neurons to a target
skeletal muscle cell, eliciting movement of that muscle
What is the function of the autonomic nervous system?
Ans✓✓✓Controls involuntary movement
What can the autonomic nervous system be further divided into?
Ans✓✓✓Sympathetic - fight or flight
Parasympathetic - rest and digest
What do neurons do? Ans✓✓✓Structural units of the nervous system.
Allow for communication within and between the CNS and PNS.
Can generate and transmit rapid electrical signals to other neurons
Neuron Structure Ans✓✓✓cell body, dendrites, axon
What does the cell body do in a neuron? Ans✓✓✓Functions to transfer
electrical signals from the dendrites to the axon
