/Transverse
What /is /the /purpose /of /the /blood-brain /barrier? /Describe /its /maintenance /from /a /cellular
/level. /- /correct /answer(s) /✔✔ /The /blood-brain /barrier /is /a /diffusion /barrier /which /prevents
/most /particles /from /entering /the /central /nervous /system /tissue, /keeping /the /brain /and /spinal
/cord /separate /from /general /blood /circulation. /The /blood-brain /barrier /is /formed /by /the
/relatively /impermeable /brain /capillaries, /due /to /the /glial /cells /astrocytes. /Maintenance /of
/the /blood-brain-barrier /is /important /to /provide /a /stable /chemical /environment /for /the
/nervous /system.
All /the /following /are /functions /of /the /hypothalamus /except: /
A. /Maintain /homeostasis /
B. /Controls /the /pituitary /gland /
C. /Links /the /nervous /and /endocrine /systems /
D. /Relays /sensory /impulses /to /the /cerebrum /- /correct /answer(s) /✔✔ /D

/brain /but /instead /are /stored /throughout /the /cerebral /hemispheres. /The /hippocampus /acts /as
/a /memory /center /to /help /with /memory /storage /and /retrieval. /The /involvement /of /the /limbic
/system /explains /why /emo!onally /charged /events /result /in /our /most /vivid /memories.
Which /statement /is /false /concerning /the /brainstem? /
