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

34

Internal layer
Delicate layer that adheres to the surface of the brain and spinal cord

PIA MATER
