Layers of the Cerebrum

Study These Flashcards
A

Gray matter
White matter
Basal nuclei

25
internal islands of gray matter
Basal nuclei
26
The Outer layer of the cerebrum which composed mostly of neuron cell bodies
Gray matter
27
The layer of the cerebrum that are Fiber tracts inside the gray matter
White matter
28
It connects hemispheres
corpus callosum
29
an example of white matter is
corpus callosum
30
Sits on top of the brain stem which is Enclosed by the cerebral hemispheres
Diencephalon
31
the three parts of the diencephalon
Thalamus Hypothalamus Epithalamus
32
Surrounds the third ventricle which is The relay station for sensory impulses. The Transfers impulses to the correct part of the cortex for localization and interpretation
Thalamus
33
I is Under the thalamus. Its an Important autonomic nervous system center
Hypothalamus
34
It Helps regulate body temperature, Controls water balance, and Regulates metabolism
Hypothalamus
35
An important part of the limbic system (emotions) which The pituitary gland is attached to it
Hypothalamus
36
limbic means
emotions
37
Forms the roof of the third ventricle that Houses the pineal body. It also Includes the choroid plexus
Epithalamus
38
forms cerebrospinal fluid
choroid plexus
39
Attaches to the spinal cord
Brain Stem
40
Parts of the brain stem
Midbrain Pons Medulla oblongata
41
Parts of the brain stem
Midbrain Pons Medulla oblongata
42
Mostly composed of tracts of nerve fibers.
Midbrain
43
It Has two bulging fiber tracts which are
cerebral peduncles
44
It Has four rounded protrusions
corpora quadrigemina
45
Reflex centers for vision and hearing
corpora quadrigemina
46
The bulging center part of the brain stem which is Mostly composed of fiber tracts. It includes nuclei involved in the control of breathing
Pons
47
The lowest part of the brain stem that Merges into the spinal cord. It includes important fiber tracts
Medulla Oblongata
48
It Contains important control centers like Heart rate control Blood pressure regulation Breathing Swallowing Vomiting
Medulla Oblongata
49
Diffuse mass of gray matter along the brain stem which Involved in motor control of visceral organs.
Reticular Formation
50
plays a role in awake/sleep cycles and consciousness
Reticular activating system
