Brainstem/Cerebellum Flashcards
brainstem
relay center
midbrain
superior, just below thalamus
pons
circular portion that sticks out
medulla oblongata
inferior, continuous with spinal cord
cardiac center (medulla)
regulates heart rate, strength of contraction
vasomotor center (medulla)
controls blood pressure by regulating contraction of smooth muscle in walls of arterioles
medullary respiratory center (medulla)
regulates respiratory rate
other nuclei in medulla oblongata
coughing, sneezing, salivation, swallowing, gagging, and vomiting
cerebellar cortex
gray matter, outer region
arbor vitae
white matter deep to gray matter, tree of life
cerebellar nuclei
small areas of gray matter found deep in cerebellum
peduncles
bridges of tissue, connect cerebellum to brainstem
superior cerebellar
midbrain to cerebellum
middle cerebellar
forms floor of fourth ventricle, cerebellum to pons
inferior cerebellar
cerebellum to medulla
