Exam 3: CNS Rochet Flashcards
medulla
autonomic (involuntary) functions
includes centers for controlling respiration, cardiac function, vasomotor responses, reflexes (coughing)
pons
relays signals from the forebrain to the cerebellum
cerebellum
undergoes neurodegeneration in spinocerebellar ataxias
What makes up the hindbrain?
medulla
pons
cerebellum
What makes up the midbrain?
substantia nigra
SN pars compacta
provides input to the basal ganglia
supplies dopamine to the striatum
undergoes neurodegeneration in PD
SN pars reticulata
has output function
relays signals from basal ganglia to the thalamus
what makes up the forebrain?
cortex (cerebrum)
basal ganglia
limbic system
diencephalon
cortex
involved in processing and interpreting information
basal ganglia
striatum (caudate and putamen), globus pallidus, subthalamic nucleus
voluntary motor control, some cognitive functions
limbic system
emotions (amygdala)
memory (hippocampus)
diencephalon
thalamus: relay station to and from the cortex
hypothalamus: regulates internal homeostasis, emotions, hormonal control, and direct neural regulation
schizophrenia is considered a disease of the ________.
frontal cortex
decisions are made in the cortex and damage can affect movement, speech, personality
Which of the following brain structures is directly involved in controlling involuntary functions?
hypothalamus
thalamus
medulla oblongata
hypothalamus
medulla oblongata
Astrocytes
provides neurons with growth factors, antioxidants
removes excess glutamate (excitotoxic neurotransmitter)
support the blood-brain barrier
