Unit 6TIPS (thanks to Feinberg Footnotes) It took several weeks before the material started to make any sense to me at all. Just be persistent with your studying, and layer the information... Learn the most basic things first, then start to fill in the details. It WILL come together in the end if you work at it. Dr. Perkins' syllabi are very comprehensive, and will truly guide your studying for the exam. I used a TON of flashcards during unit 6 - almost as many as I used in unit 5! I found it helpful to really get a lot of repetition with some of the "easier" things, and then the harder stuff made more sense.
Behavioral Science—DO NOT MAKE A BIG DEAL OUT OF IT... as long as you read over the lecture notes and the recommended study guide the unit director sends our, you will be fine!
Dr. Perkins is amazing. His lecture notes should be one of the first places you go for studying for this unit. Several lecturers use experimental evidence to explain concepts in this unit; again, don't get overwhelmed by the details but get the main point that the experiment shows (e.g. all the monkey experiments). < Back TRICKS (thanks to MedicalMnemonics.com) Broca's vs. Wernick's area: effect of damage to speech center
"Broca": your speech machinery is Broken.
· Broca is wanting to speak, but articulation doesn't work, and very slow.
"Wer-nick": "were" and "nick" are both words of English language, but together they are nonsensical.
· Wernick is having good articulation, but saying words that don't make sense together.
Lower vs. upper motor neuron lesion effects
1. "STORM, Baby"
2. 'In a Lower motor neuron lesion, everything goes Down:
· STORM Baby tells you effects:
Strength
Tone
Other
Reflexes
Muscle mass
Babinski's sign
· In Lower all things go down: strength, tone, reflexes, muscle mass, and the big toe down in plantar reflex (Babinski's sign is big toe up: toe up = UMNL)
Hypothalamus: feeding vs.satiety center
"Late night snack":
LATEral is snacking [feeding] center.
Therefore, ventromedial is satiety center
Spinal tracts: simplified geography
2 posterior: cross at the medulla.
2 lateral: ipsilateral (same side).
2 anterior: cross at the spinal level.
· Note 1: Descending tracts on left of figure, ascending tracts on right.
· Note 2: For ipsilaterals: one never crosses, one crosses at the level then doubles back farther up. The ipsilateral that crosses at the level (ventral spinocerebellar) is the ipsilateral closest to the 2 anterior ones, which also cross at the level.
· Tract names in each group:
Posterior 2: lateral corticalspinal, dorsal columns. Lateral 2: dorsal spinocerebellar, ventral spinocerebellar. Anterior 2: ventral corticospinal, spinothalamic.
Spinal tracts: Gracilus vs. Cuneatus: origin from upper vs. lower limbs
Gracilus is the name of a muscle in the legs, so Fasciculus Gracilus is for the lower limbs.
By default, Fasciculus Cuneatus must be for upper limbs.
Geniculate bodies: medial vs. lateral system
MALE:
Medial=Auditory. Lateral=Eye.
Medial geniculate body is for auditory system, lateral geniculate body is for visual system.
Can expand to MALES to remember Lateral=Eye=Superior colliculus (thus medial is inferior colliculus by default).
Auditory pathway
"Hungry Girls 8(ate) Nothing To SLIM Themselves":
Hair cells
spiral Ganglion
cranial nerve 8
cochlear Nuclei
Trapezoid body (decussation of ventral nuclei)
Superior olivary nucleus
Lateral leminiscus
Inferior colliculus
Medial geniculate body
Transverse temporal gyrus
Spinothalamic tracts: function of lateral vs. ventral
"Lumbago is conveyed by the Lateral tract":
Lumbago is lower back pain. Therefore lateral tract conveys pain, so by default, ventral tract conveys light touch.
Cerebellar functional areas
Anatomical shape/location of cerebellar areas is a key to their function and related tract.
· Vermis = Spinocerebellar = Axial equilibrium.
Vermis: right down the axis of cerebellum, and vertically segmented like a spinal column.
· Flocculonodular lobe = Vestibulocerebellar = Ear, eye, body coordination.
Flocculonodular lobe: flares out to the edges, just like ears.
· Hemispheres of cerebellum = Cerebrocerebellar = Peripheral coordination.
Hemispheres: around periphery of cerebellum, and tract to cerebral hemispheres.
Olivary nuclei: ear vs. eye roles
Superior Olivary nucleus: SOund localization.
Inferior olivary nucleus is therefore the one for sight [tactile, proprioception also]. < Back SITES Darren Boyd's (Class of 2011) Neuroanatomy Study Guide: Lab Study Guide.ppt Some good sites to study neuro: http://medicalschoolresources.com/index.php?category=Neurology You can always count on Pinky and the Brain for all your educational needs: http://www.youtube.com/watch?v=snO68aJTOpM -Member of Class of 2012
