and glands to respond.
What Are The Main Cell Neurons and Neurogila
Types of Nervous
System?
-one of the main cells in the NS
What are Neurons? - respond quickly to changes/stimuli
- conduct electric impulses via neurotransmitters
- one of the main cells in the NS
What is a Neuroglia Cell? - protect, support, insulate, and nourish neurons
- do not conduct electrical impulses like neurons
1. sensory receptor = sensor input
What Is The Flow Of
2. brain and spinal cord = intergration
Information In The NS?
3. effector = motor output
What is the CNS Made the brain and spinal cord
Up Of?
What Is The PNS Made cranial nerves and spinal nerves. connects CNS to
Up Of? other body parts
- nervous system receives information
What Is Sensory - sensory receptors gather info by detecting
Function? changes
- info is carried to the CNS
, - NS coordinates sensory info to create sensations,
What Is Integrative memory, and thoughts
Function? - NS makes decisions on body's response to sensory
info
- decisions are acted upon
- impulses are carried to effectors ( muscles and
What Is Motor Function? glands)
- divisions of motor portion of PNS: somatic NS and
autonmic NS
it transmits VOLUNTARY instructions to skeletal
What Is The Somatic NS?
muscles.
What Is The Autonmic transmits INVOLUNTARY instructions from the CNS
NS? to smooth muscles, cardiac muscle, and glands.
