What are the 2 main parts of Nervous System?
1) CNS
2) PNS
PNS is divided into what 2 systems/divisions?
1) Sensory division (afferent)
2) Motor division (efferent)
Define:
Sensory Division
You're taking in info
& it's going towards CNS (brain & Spinal cord)=afferent signal
Define:
Motor Division
(Info is going)
Away from brain/spinal cord; Carries signal from CNS to gland & muscle cells that carry out the body's responses.

Ex: Writing notes now
What is
Visceral Sensory Division?
Internal you have no control; Carries signals mainly from the viscera of the thoracic & abdominal abdominal cavities, such as the heart, lungs, stomach, & urinary bladder
What is
Somatic Sensory Division?
Carries signals from receptors in the skin, muscles, bones, & joints
What are the 2 divisions of
Visceral Motor Division?
1) Sympathetic Division
2) Parasympathetic Division
Define:
Sympathetic division?
Fight/flight response
What is Parasympathetic division?
Normal day to day
What are the 3 general classes of neurons / "Nervous System Mantra"
1) Sensory (afferent) neurons
2) Interneurons
3) Motor (efferent) neurons
Describe:
Sensory (afferent) neurons?
Take info ; stimuli
Describe:
Interneurons?
Incorporate info ; process stimulus
Describe:
Motor neurons?
Response ; respond
What are the 3 Properties of Neurons? (Which enables them to communicate with other cells)
1) Excitable
2) Conductive
3) Secretory
Describe
(Property of Neuron's) property:
Excitable
These cells respond to stimuli
Describe
(Property of Neuron's Property: Conductive)?
(Electricity)
able to send out signal & activate other cells
Describe
(Property of Neuron's Property: Secretory)?
Releasing neurotransmitter or some type of electrical signal, (causing a response to the body)
Describe the structure of a neuron (name at least 5 parts)
1) soma
2) nucleus
3) processes of cell neuron:
-dendrites
-axon
-axon hillock
Define:
Soma
Cell body of neuron
Define by function:
dendrites
take in info
Define by function:
Axon
send/release out info
Define by function:
Axon hillock
part where neuron start to form axon
Define:
Axonal transport?
The two-way passage of proteins, organelles, & other materials along an axon.
Define:
Anterograde transport
Movement away from the soma down the axon
Define:
Retrograde transport
Movement up the axon toward the soma
What are the 2 types of axonal transport?
1) Fast axonal transport
2) Slow axonal transport
What are the 2 types of Fast Axonal Transport?
1) Anterograde axonal transport
2) Retrograde axonal transport
Define:
Somatic Motor Division?
Carries signals to the skeletal muscles. This output produces muscular contractions that are under voluntary control, as well as involuntary muscle contractions called "somatic reflexes"
