Neurotransmitters

Neurotransmitters
  Acetylcholine (ACh)
  Affects contraction in
muscle
  Glutamate
  Excite neighboring
neurons
  Norepinephrine &
  Serotonin
  Appetite, sleep,
memory, temperature,
mood, cardiov system,
endocrine system
Epinephrine
  Fight or flight
  Dopamine
  Mood, motivation,
pleasure
  GABA
  Inhibitory
Drugs & Neurotransmitters
  Cocaine
  Serotonin reuptake
inhibitor
  Methamphetamine
  Causes release of
serotonin, dopamine &
epinephrine and inhibits
reuptake
  Heroin
  Endorphin agonist
  Psychedelics
  Serotonin receptor
agonist,  glutamate
  MDMA
  Release of serotonin,
dopamine, oxytocin
  Cannabis
  Cannabinoid agonist
Long-distance transmission
  Myelin sheath
  Helps electrical signal
transmission over
longer distances
  Signals sent faster
  Less likely to lose
propagation of action
potential
  Multiple Sclerosis
  WBCs attack myelin
Central Nervous System
  Brian
  Spinal chord
Peripheral nervous system
  Everything else
Peripheral NS
  Somatic
  Skin
  Tendons
  Muscles
  Autonomic
  Organs & glands
  Sympathetic
 
Fight-or-flight
  Parasympathetic
  Housekeeping
Peripheral NS
  Somatic
  Skin
  Tendons
  Muscles
  Autonomic
  Organs & glands
  Sympathetic
 
Fight-or-flight
  Parasympathetic
  Housekeeping
Spinal Chord
  Connects peripheral NS
to the brain
  Reflexes
  Sensory neurons
  Motor neurons
  Vertebral column
  Meninges – protective
coverings
  Meningitis
The vertebrate brain
  Brain stem
  Pain, temp, itch
  Medulla oblongata
 
Reflexes, respiration,
circulation
  Cerebellum
  Motor coordination
  Thalamus
  Relay & sorting
  Hypothalamus
  Homeostatis – thirst,
sex, hunger
The Human Brain - Cerebrum
  Broca’s area –
language
  Parietal lobe – spatial
sense & navigation
  Frontal lobe – executive
functions, reward,
planning, drive
The Human Brain - Cerebrum
  Temporal lobe –
auditory perception,
long-term memory
  Occipital lobe - visual
  Corpus callosum – the
bridge
