Flashcards in ch 14 test Deck (47):
1
gyri
elevated ridges of cerebral cortex
2
sulci
shallow depressions of the cerebral cortex
3
fissures
deep grooves of the cerebral cortex
4
diencephalon
links cerebrum w brain stem; 3 divisions- left thalamus, right thalamus, and hypothalamus
5
thalamus
(bird eye) relays and processes sensory info
6
hypothalamus
(bird beak) hormone production, emotion, and autonomic function
7
pituitary gland
in diencephalon, major endocrine gland connected to hypothalamus via infundibulum, interfaces nervous and endocrine systems
8
mesencephalon
midbrain, processes sight, sound, associated reflexes, and maintains consciousness
9
pons
connects cerebellum to brain stem and is involved in somatic and visceral motor control
10
medulla oblongata
connects brain to spinal cord, relays info, regulates heart rate, blood pressure, and digestion
11
telencephalon
becomes cerebrum
12
metencephalon
forms cerebellum and pons
13
myelencephalon
becomes medulla oblongata
14
ependyma
lines ventricles
15
septum pellucidum
seperates lateral ventricles
16
3 largest dural folds
falx cerebri, tentorium cerebelli, falx cerebelli
17
falx cerebelli
contains superior and inferior sagital sinus
18
choroid plexus
secrete CSF, remove waste products and adjusts composition
19
arachnoid granulations
large clusters of villi that absorb CSF into venous circulation
20
jugular
drains brain
21
carotid and vertebral artery
feeds brain
22
4 breaks in the BBB
1. portions of the hypothalamus
2. posterior lobe of pituitary gland
3. pineal gland
4. choroid plexus
23
medulla oblongata nuclei groups-3
autonomic nuclei, sensory and motor nuclei of cranial nerves, relay stations along sensory and motor pathways
24
medulla oblongata reflex centers
cardiovascular centers, respiratory rhythmicity centers
25
medulla oblongata nerves
8-12
26
relay staions of medulla oblongata
nucleus gracilis and nucleus cuneatus (somatic sensory info)
solitary nucleus (visceral sensory info)
olivary nuclei (somatic motor commands)
27
pons cranial nerves
5-8
28
pons- nuclei involved w respiration
apneustic and pneumotaxic centers
29
transverse fibers
link nuclei of pons w opposite cerebellar hemi
30
cerebellum function
adjusts posture, fine-tunes conscious and subconscious movements
31
folia
surface of cerebellum, highly folded neural cortex
32
purkinje cells
large branched cells in cerebellar cortex that receive input from 200,000 synapses
33
arbor vitae
highly branched, internal white matter of cerebellum that relay info to purkinje cells
34
ataxia
damage from trauma, stroke, or drinking, loss of muscle coordination
35
superior colliculus
visual nuclei in tectum of midbrain
36
inferior colliculus
auditory nuclei in tectum of midbrain
37
substantia nigra
part of tegmentum of midbrain that reg act in basal nuclei
38
cerebral peduncles of midbrain
connect primary motor cortex w motor neurons in brain and spinal cord, carry ascendin sensory info to thalamus
39
pineal gland
found in epithalamus and secretes melatonin
40
thalamus function
filters ascending sensory info for primary sensory cortex and relays info between basal nuclei and cerebral cortex
41
thalamus anterior goup
part of limbic system
42
thalamus medial group
integrates sensory info for projection to the frontal lobes
43
thalamus ventral group
projects sensory info to primary sensory cortex; relays info from cerebellum and basal nuclei to motor area of cerebral cortex
44
thalamus pulvinar
integrates sensory info for projection to association areas of cerebral cortex
45
lateral geniculate nuclei
project visual info to the visual cortex
46
medial geniculate nuclei
project auditory info to the auditory cortex
