Brainstem Anatomy Flashcards
what horn of the spinal cord carries information away from the CNS (efferent/motor)
Anterior horn or Ventral horn
what horn of the spinal cord carries information towards the CNS (afferent/sensory)
Posterior horn or Dorsal horn
what artery is a branch of the MCA and is clinically significant in strokes , it supplies deep structures of brain
Anterior choroidal artery
3 main functions of the brainstem
conduit of info., cranial nerves, complex integrative functions
3 main subdivisions of the brainstem rostral to caudal
midbrain, pons, medulla
what is the difference b/w the open and closed medulla
open medulla has little part of 4th ventricle behind it, closed medulla has cerebellum behind it
what is considered the open medulla, the rostral or caudal medulla
rostral medulla
what plane of the brainstem is the superior calliculi
rostral midbrain
what plane of the brainstem does the inferior calliculi sit
caudal midbrain
the middle cerebral peduncle is in what part of the brainstem
pons
what part of the brainstem houses the olive and pyramid
rostral medulla
brainstem tissue anterior to the ventricle cavity
tegmentum
brainstem tissue posterior to the ventrical cavity, also referred to as the “roof”
tectum
what is the main fiber tract on the anterior brain
corticospinal tract
what is the main fiber tract in the anterolateral brain
spinothalamic tract
