Somatic
or Autonomic


Sensory

Integrative

Motor


Conducting Nerve Impulses
Serving as a Center for spinal reflexes

How it works with other body systems.
 Cerebrum
 Diencephalon
 Brainstem
 Cerebellum



2 Hemispheres with corpus callosum
5 nerve centers (Frontal, temporal, parietal, occipital, insula)
Cerebral cortex


Interpret sensory impulses, initiate voluntary
muscle movements, stores memory
Function depends on region; 3 Regions:
Motor
 Sensory
 Association

Impulse


Down
brainstem
Through
spinal
cord
Synapse
Muscle
fibers
Motor Speech Area- mouth, tongue, layrnx =
speech
Frontal Eye Field- eyes and eyelids (voluntary)
Sensory
Interpret impulses
from sensory
receptors
Parietal lobes
Occipital lobes
Temporal lobes
Association
Interpret sensory
experiences, oversee
memory, reasoning,
verbalizing,
judgment, emotion
Anterior portion
Lateral portion
General
Interpretative area
Thalamus- central relay station
 Hypothalamus- regulates homeostasis
 Limbic System- controls emotional

experience and expression





Midbrain- connects brainstem and spinal cord, reflex centers
Pons- separate midbrain and medulla, relay impulses
Medulla Oblongata- everything passes through it
Reticular Formation- activates cerebral cortex
Choroid Plexuses- secrete cerebrospinal fluid



Superior Peduncles
Inferior Peduncles
Middle Peduncles


Functions independently
Regulates viscera
Sympathetic
Energy
expending,
stressful, or
emergency
Parasympathetic
Ordinary,
restful
conditions
 Touch
& Pressure
 Temperature
 Pain



Free-Nerve Endings- epithelial tissue
Meissner’s Corpuscles- connective tissue (no hair)
Pacinian Corpuscles- connective tissue (subcutaneous)
Warm
•70°-113°F
•More=Pain
Cold
•50°-68°F
•Less=Pain
*Adapt Rapidly




Protect
Adapt Poorly
Decreased blood flow accompanied by lower
oxygen concentration
Viscera
Acute
Chronic
• Thin, myelinated
• Rapid, sharp pain
• Skin
• Thin, unmyelinated
• Slow, Dull ache
• Deeper
• Can cause prolonged suffrage
Can cause prolonged suffrage
Regulation of pain impulse
Both have their own neuron
process
 Flavor- a combination of what
you taste and smell


Multiple Sclerosis- damages the myelin sheath
on an axon

Amyotrophic Lateral Sclerosis (ALS)Neurodegenerative Disease that effects the
neurons in the brain and spinal cord.
