PHYSIOLOGY
Brain
Corpus Callosum:
Transmits messages between the two cerebral hemispheres
Medulla / Oblongota:
Vital reflex center
Hypothalamus:
Regulates homeostasis; in charge of autonomic n.s. and endocrine n.s
Cerebral Aqueduct:
Connects the 3rd and 4th ventricles
Cerebellum:
Maintains equilibrium and posture
Pons:
Plays a key role in REM sleep and second in respiratory
Cerebrum:
Conscious thought process and all complex intellectual function
Midbrain:
In charge of optic and auditory reflex
Lateral ventricles:
Contain cerebralspinal fluid
Thalamus:
Sensory relay
Diencephalon
relays sensory information
Hypothalamus
: Homeostasis
Epithalamus:
connects the limbic system to other part of the brain
Subthalamus:
regulates skeletal muscle movements
Gyrus:
Raised area in brain wrinkling
Solcus
: Depressions between the gyri
Lobes:
Frontal lobe:
Motor control of skeletal muscles
Occipital lobe
: Visual interpretation/association
Temporal lobe:
Interpretation and storage of sounds/ smell
Parietal lobe:
Sensory/touch; expression of emotion
Cranial nerves
I Olfactory nerve
: smell
II Optic nerve:
sight
III Oculomotor nerve:
eye
IV Trochlear nerve:
eye
V Trigeminal nerve:
face
VI Abducens
nerve: eye
VII Facial nerve
: Taste

Stroke
: A sudden interruption in the blood supply of the brain
Ischemic Stoke:
Caused by an abrupt blockage of an artery
Hemorrhagic Stroke:
Bleeding into brain tissue when blood vessel bursts
Regions of matter
Gray matter:
Region with cell bodies and dendrites
Unmyelinated
: No myelin sheath surrounding it
White matter:
Region with axons
Myelinated
: Lipid-rich myelin insulating the axons
Left with no movement of right arm, fingers and speech
Damage to left hemisphere, Frontal lobe,
Excessive alcohol consumption
Causes a stroke to occur
Sudden interruption in blood supply
Causes internal bleeding in the brain
Prevents production of blood clots
Damage to live
Alcohol abuse
Alcohol abuse
Causes liver damage
Prevents blood clotting
Bleeding in the brain
Frontal lobe
Damage to fine motor movements
No ability to move fingers
No more piano playing
Damage to left hemisphere
In charge of speech
As well as right side of body
Paralyzed
More alcohol abuse
More damage to brain
Another stroke
Telling his wife
Husband may not be able to play piano
Alcohol affected his motor lobes
If continues to drink
Results in another stroke
Left paralyzed or dead
Condition over time
Continues to drink
Outcomes worsens
More damage to tissue over time
Risk of another stroke
May end up dead or paralyzed
Stops drinking
Symptoms may lesson
Therapy needed to be able to walk again
