MAJOR DIVISIONS & SUBDIVISIONS OF NERVOUS SYSTEM
CLASSIFICATIONS OF NEURONS
NEUROTRANSMITTERS
CRANIAL NERVES
VII- Facial
VIII- Vestibulocochlear
VI- Abducens
IX- Glossopharyngeal
V- Trigeminal
X- Vagus
XI- Accesory
IV- Trochlear
VII- Hypoglossal
III- Oculomotor
II- Optic
I- Olfactory
MAJOR PARTS & FUNCTIONS OF SPINAL CORD
DISORDERS/DISEASES
Damage To Primary Motor Cortex
- stroke (paralysed muscles)
Damage to Primary Visual Cortex
- results in functional blindness, unable to comprehend what is being looked at
Hypothalamic disturbances
- servere body wasting, obesity, sleep disturbances, dehydration, emotional imbalances
Alzheimer's Disease
- results in dementia, key proteins appear to be misfolded and malfunctioned (memory loss, short attention span, disorientation)
Parkinson's disease
- degeneration of of dopamine-releasing neurons, basal nuclei deprived of dopamine become overactive (treatments: deep brain simulation and gene therapy)
Huntington's Disease
- hereditary disorder caused by accumulation of protein in brain cells(symptoms: jerks) later marked by mental deterioration (treatments: drugs that block dopamine effects or stem cell implant)
REFLEX ARC(major parts & functions)
MAJOR PARTS & FUNCTIONS OF BRAIN
DRUGS OF ABUSE(mouse party)
Marijuana
- inhibitory neurotransmitters, binds canabionic receptors allowing dopamine to squirt into synapse, feeling relaxed and calm
Methamphetamine
- dopamine transmitters, meth enters dopamine esicles causing transporters to work backwards and pump dopamine into the synapse and binds to receptors over stimulating cell, causes intense pleasure and exhilaration (addictive)
Ecstasy
- seritonin neurotransmitters, confuses receptors and causes it to move in reverse, ejecting seritonin out of cells, moody, sleepy, perception, appetite
Alcohol
- inhibitor neurotransmitter (GABBA) and glutamate neurotransmitter, alcohol makes receptors even more inhibitory and goes into glutamate from exiting the cell
Cocaine
- Dopamine neurotransmitter, cocaine blocks dopamine transporters causing the cell to overstimulate dur to the dopamine binding continuously, causes fidgeting and unable to be still
LSD
- serotonin neurotransmitters, LSD interacts with particular sensory receptors (serotonin receptor type land 2) exciting them, causes wakefulness and startled responses
Heroine
- interfears with inhibitory neurotransmitters, turns off dopamine inhibition, flooding synapse, feeling of sidation and well being
