Divisions of the NS
Functional Divisions of NS
Funct. Division Cont.
100

It's role;

Controller, regulator of voluntary and involuntary movement/function; Center of all mental activity

100

Cerebrum, Cerebellum, Brainstem, Diencephalon...

Four main cranial regions
100

branches of the nervous system

central nervous system and peripheral nervous system

100

Ganglia (neurons) and nerves (axons)

PNS

100

Fight or flight

Sympathetic, visceral; regulated by the hypothalamus

acceleration and constriction

200

Cerebral palsy, aphasia, parkinsons, stuttering, TBI...

Occur when NS is impaired;(all relate to speech and language)

200
The four lobes of the brain (from front to back)
Frontal, parietal, temporal and occipital
200

The brain and spinal cord are found within this

central nervous system

200

Nuclei (neurons) and tracts (axons/white matter)

CNS

200

Rest and digest

Parasympathetic; slowed HR, reduced BP; deceleration; dialation

300

Travels along the neuron pathways while electrical charges move across each neural cell membrane

An impulse 
300

3/4 of the brains volume, controls higher functioning (reasoning, speech, vision)

Cerebrum

300

the peripheral nervous system breaks off into these two categories

Somatic and Autonomic (sympathetic and parasympathetic)

300

Final common pathway

Cranial and spinal nerves to muscles and glangs

300
Both of these coactivate and affect cognition and movement

Parasympathetic and sympathetic

400

Disruptions in NS can lead to disorders in...

Speech and language

400

Second largest part of brain, carries signals to the brain and spinal cord, coordinates muscle movements and posture

Cerebellum

400

In this part of the nervous system, cranial and spinal nerves receive and integrate input from the brain and sensory receptors before they go out to all muscles and glands

Peripheral Nervous system

400

Sends motor info to the PNS and receives sensory info from the PNS

CNS

400

Division of NS vital to SLPs

Somatic; controls of muscles arise mostly from motor areas of the brain with neural impulses sent through the descending motor tracts through the cranial and spinal pathways

500

ions moving across the membrane causes the impulse to move along the ...

Nerve cells

500

Grouping of thalamus, hypothalamus, and the pituitary gland, working together to produce and regulate neural chemicals

Diencephalon 

500

Efferent ... exiting

Motor nerves from CNS to PNS 
500

Autonomic NS

Influences the function of HR, digestion, respiratory and arousal; fight, flight or freeze; largely unconscious 
500

Somatic NS

Voluntary; nonvisceral;
