NEURO-ANATOMY
The Bell-Magendie Law:
In the door
and out the vent -
that's how spinal
info's sent!
Sara the ballerina
has a helluva
Cerebellum.
If you see a
HIPPO on CAMPUS,
you'll never forget!
Use your Tectum
to detect 'em,
and Tegmentum for
momentum.
The Meninges PAD the Brain
P = Pia mater
A = Arachnoid space
D = Dura mater
THALAMIC NUCLEI
VISION @ LGN = Light
(Lateral Geniculate Nucleus)
AUDITION @ MGN = Music
(Medial Geniculate Nucleus)
TOUCH @ VPN =
Very Personal
(Ventral Posterior Nucleus)
SMELL @ DMN = Dog Muzzle
(Dorsal Medial Nucleus)
MOTOR @ VLN = Victory Lap
(Ventro-Lateral Nucleus)
MEMORY @ MDN = Memory Doctor
(Medio-Dorsal Nucleus)
REFLEXES
Pain Withdrawl Reflex:
Touch something hot
stimulate the nociceptor,
but before your brain can say
"touch that never ever!"
inter-neuron in the spine
says "contract the flexor!"

DEVELOPMENT
Cells that fire together
wire together!
NEURONS
Neurotransmitters:
Bind to post
but don't go in -
float back home
to be used again
The resting cell
is polarized -
more positive out
than it is inside.
The resting cell
is like a salted banana -
full of Potassium (K+) inside,
while coated with Sodium (Na+)
and Chloride (CL-) outside.
EPSP
= Excitatory Post Synaptic Potential
= Cell is HYPO-polarized.
When you're excited, say "O!"
IPSP
= Inhibitory Post Synaptic Potential
= Cell is HYPER-polarized.
When you're inhibited, say "-ER!"
SEX
Hypothalmic Nucleus
most active in...
...Females = VMH
(Ventro-Medial Nucleus)
Venus Must Have!
...Males = SDN
(Sexually Dimorphic Nucleus)
