A deep fold within the cerebral cortex is a
Fissure
27
The inside of the cerebrum consists of mostly
White matter
28
The motor sensory and association cortex are the 3 ___ of the cerebral cortex
Functional regions
29
Controls voluntary muscle movements
Motor region
30
Controls muscles needed for speech
Brochas area
31
Controls movement of the eyelids
Frontal eye field
32
Interprets impulses from the sensory receptors
Sensory cortex
33
Controls higher level thinking like analysis interpretation memory reasoning
Association cortex
34
one main center of the association cortex is called
General interpret area
35
The protective layers covering the brain
Meninjies
36
The outermost protective layer covering the brain which contains many blood vessels and nerves and is attached to the skull
Dura Mater
37
The middle protective layer covering the brain which is where like in structure and it's function is basically unknown to scientists
Arachnoid mater
38
The innermost protective layer covering the brain which contains many blood vessels and nerves and is attached directly to the brain
Pia mater
39
What system creates a memory of good and bad experiences
Limbic system
40
What is an enlarged continuation of the spinal cord with white matter on the outside and gray matter on the inside the gray matter relays acending impulses and acts as a control center
Medulla Oblongata
41
Is responsible for waking and sleeping, Coma occurs if not working
Reticular formation
42
Is located between cerebral hemispheres mostly gray matter surrounds the third ventricle is the most superior region of the brain stem
Diencephalon
43
Maintains homeostasis is a link between nervous system and the endocrine system is a part of the diencephalon
Hypothalamus
44
Is the relay station for sensory impulses is part of the diencephalon
Thalamus
45
Is a control center of the medulla Oblongata sends impulses that regulate rate rhythm and depth of breathing
Respiratory center
46
Is the control center medulla Oblongata of the it sends impulses to heart to increase or decrease rate
Cardiac center
47
Is a control center of the medulla Oblongata it sends contracting or dilating impulses to smooth muscles with in the blood vessels
Vaso motor center
48
A center for nerve pathways if the area is damage it is difficult to remain alive
Brainstem
49
A dorsal portion that relays imposes between cerebrum and medulla Oblongata and a ventral portion that relays impulses between cerebrum and cerebellum
Pons
50
Middle area of the brainstem it contains bundles of nerve fibers that doing the cerebral cortex and for parts of the brainstem
Mid brain
51
Medulla Oblongata sends this message that will cause the blood vessels to contract
Vaso constriction
52
Medulla Oblongata Sends a message for which will cause the blood vessels to dilate
Vaso dilation
53
The link to the endocrine system they secrete hormones and are part of the diencephalon
Pineal and pituitary glands
54
3 parts of the brain and what's why do
Cerebellum-balance Cerebrum-controls/interprets senses voluntary movements Brain stem- life lol
55
Cerebrum outer layer
Cerebral cortex
56
Surface area of the brain is increased by folds, or
Convolutions
57
