Flashcards in anatomy of brain Deck (34):
1
elevated ridges
gyri
2
shallow groove
sulcus
3
divide the cerebrum into
lobes
fissure
4
involved in planning, problem solving, decision making
controls behavior and emotions
frontal
5
controls sensation (touch, smell and taste)
parietal lobe
6
- controls reception and perception
of visual information
- perceives shapes and colors
occipital
7
involved in olfactory and
auditory sensations
temporal
8
- located at the parietal lobe
gustatory
9
located at the posterior part of
the occipital lobe
VISUAL
10
found at the temporal lobe
AUDIORY
11
located at the medial temporal
lobe
OLFACTORY
12
Outer layer OF CEREBRUM
Composed mostly neurons
gray matter
13
layer of cerebrum
Fiber tracts inside the gray matter
-transmit impulses
Example: corpus callosum connects hemispheres
white matter
14
Sits on top of the brain stem
Enclosed by the cerebral hemispheres
Made of
Thalamus
Hypothalamus
Epithalamus
DIENCEPHALON
15
Surrounds the third ventricle
Transfers impulses to the correct part of the cortex for localization and interpretation
THALAMUS
16
- serves as connection bet.
right and left thalamus
INTERTHALAMIC DIVISION
17
- fiber tract
- connects the two
cerebral hemispheres
corpus callosum
18
- bet. Corpus callosum
and fornix
- membranous partition
- separates right and left
lateral ventricles
septum pellucidum
19
Inferior to the thalamus
Most inferior part of diencephalon
Maintains homeostasis
Controls body temperature, hunger and thirst
hypothalamus
20
- funnel shaped stalk
- extends from the floor
of the hypothalamus
to the pituitary gland
infundibiulm
21
- hangs from the
anterior floor of the
hypothalamus
- produces hormones
Pituitary gland/hypophysis
22
- posterior to pituitary
gland
- reflex center involved
in olfaction (sense of
smell)
mammillary body
23
Small area superior and posterior to the thalamus
Forms the roof of the 3rd ventricle
Houses the pineal gland and choroid plexus of third ventricle
epithalamus
24
- knots of capillaries
within each ventricle
-covered with
ependymal cells
- forms the
cerebrospinal fluid
choroid plexus
25
About the size of a thumb in diameter
3 inches long
connects the spinal cord to the brain
brain stem
26
Superior to the pons
Extends from the mammillary body to the pons inferiorly
midbrain
27
- rounded protrusions
- superior and
inferior colliculi
- Reflex centers for
vision and hearing
corpora quadrigemina
28
tiny canal that
connects 3rd ventricle
to the 4th ventricle
AQUEDUCT OF SYLVIUS
CEREBRAL AQUEDUCT
29
The bulging center part of the brain stem
Inferior to the midbrain
Superior to the medulla oblongata
controls breathing swallowing and balance
PONS
30
The lowest part of the brain stem
Merges into the spinal cord
Contains important control centers
Heart rate control
Blood pressure regulation
Breathing
Swallowing
Vomiting
MEDULLA OBLONGAT
31
Inferior to the occipital lobe
2 hemispheres
Outer cortex (gray matter)
Inner region of white matter (arbor vitae)
Provides precise timing for skeletal muscle activity
Controls balance/
equilibrium
CEREBELLUM
32
Double-layered external covering
Thickest and strongest layer
DURA MATER
33
Middle meninx
Web-like
ARACHNOID MATER
