the medullary respitory center controls
breathing rate
28
the medullary respitory center contains
dorsal and central respitory groups.
29
the medullary respitory center communicates with
pontine respitory center
30
the cerebellum is the ________ brain area
2nd largest
31
e cerbellum is located
beneath occipital lobe
32
cerebellar cortex- convoluted surfae with
folia (folds)
33
how many cerebral hemispheres are there
2
34
each hemisphere of cerebellum has an
anterior and posterior lobe seperate by primary fissure
35
vermis is a
narrow band of cortex between left and right lobes
36
the vermis receives
sensory signals regarding torso and balance
37
the three regions of the cerebellum are
cerebellar cortex, arbor vitae, deep cerebellar nuclei
38
cerebellar cortex is the
outer gray matter
39
the arbor vitaw is the
internal region of white matter
40
the deep cerebellar nuclei is the
gray matter
41
cerbellum purpose is to ______and______ movements
coordinate;fine tune
42
the cerbellum ensures muscle activity follows the correct
pattern
43
the cerebellum stores_______ of previously learned moves
memories
44
thje cerebellum also regulates activity along _______ and ____ motor paths
voluntary and involuntary
45
the cerbellum adjusts movements initiated by te
cerebrum
46
the cerebellum also helps maintain
posture and equilibrium.
47
how does cerebellum maintain posture and equilibrium
receives propricoceptive information from muscles and joints
48
the cerebellum also receives ______-and ________
motor plans and sensory feedback
49
the cerebellum may generate
error correcting signals to be sent to premotor and primary motor cortex
50
the limbic system is composed of
reticular formation and hippocampus
51
emotion brain is
limbic system
52
hippocampus helps form
long term memories
53
reticular formation has to do with
alterness/awareness of certain sensations
54
reticular formation is
loosley organized gray matter of brainstem
55
retilcular formation is necessary for
