Neuroanatomy Flashcards
What is role of Parasympathetic Nervous System?
Pupil constriction, Bronchoconstriction, Detrusor contraction and sphincter relaxation, and penile erections.
Orbitofrontal syndrome
Socially inappropriate behaviors as well as poor impulse control with disinhibition.
The lateral convexity syndrome
Dysexecutive symptoms.
Mesial frontal syndrome
Amotivation.
Orbital apex - which CN are located
2, 3, 4, 6
Superior Orbial Fissure
3, 4, 6
CN2 exit
Optic canal
Thalamic astasia
Alert and awake patient with normal strength who cannot stand and sometimes sit unassisted for several days after an acute stroke. The patient may have varying degrees of sensory loss. They typically fall backwards or to the side opposite of the lesion.
Lesions of the subthalamic nucleus
hemiballismus
Lesions of putamen
weakness and chorea.
Injury to the vestibular nucleus
nystagmus and a tendency to fall toward the side of the lesion.
Cortical areas critical for gait include
the medial frontal region, the paracentral lobule, and the supplementary motor cortex.
One and half syndrome ( left eye can not move )
left medial longitudinal fasciculus and left abducens nucleus.
Superior Visual field
Temporal lobe as Meyer’s loop.
Inferior lip of the contralateral calcarine sulcus.
Cheiro-Oral Syndrome
is a lacunar syndrome characterized by contralateral sensory deficits of the mouth and hand. It typically localizes to the VPM and VPL in the thalamus.
