Finals

Question 1

Dura Mater (outer)

Answer 1

A tough outer layer of dense irregular connective tissue

Question 2

Arachnoid mater (middle)

Answer 2

A spiderweb-like layer of collagen and elastic fibers, located inside the dura mater

Question 3

Pia mater (inner)

Answer 3

A thin, transparent, vascular connective tissue membrane that covers the surface of the spinal cord and membrane

Question 4

Dural venous sinuses

Answer 4

Some portions of the dura mater around the brain, are double-layered and contain veins

Question 5

Subdural space

Answer 5

Potential space between subarachnoid matter and pia mater of spinal cord and brain

Question 6

Subarachnoid mater

Answer 6

Potential space between subarachnoid matter and pia mater of spinal cord and brain

Question 7

Cerebrospinal fluid

Answer 7

Protects and cushions the spinal cord and brain. Formed by the ventricles of the brain

Question 8

Ventricles

Answer 8

CSF-filled cavities within the brain

Question 9

Choroid plexuses

Answer 9

Line the inside ventricle walls

Question 10

Blood-CSF barrier

Answer 10

Prevents harmful substances from getting into the brain

Question 11

Circulation of CSF

Answer 11

CSF from the ventricles flows into the subarachnoid space and central canal. CSF is reabsorbed through arachnoid villi from the subarachnoid space of the brain into the dural venous sinuses in the dura mater

Question 12

Capillaries

Answer 12

Consists of simple squamous epithelium with small intercellular clefts between the epithelial cells

Question 13

Blood-brain barrier

Answer 13

O2, CO2, alcohol, and most anesthetics cross the BBB easily, while glucose and other nutrients cross the BBB by transport proteins, also prevents the passage of neurotoxins that can harm neurons

Question 14

Cerebrum

Answer 14

The largest part of the brain, conscious thought and learning occurs here

Question 15

Cerebellum

Answer 15

The second largest part of the brain

Question 16

Diencephalon

Answer 16

Consists of the thalamus, hypothalamus, and pineal glands

Question 17

Brain stem

Answer 17

Continuous with the spinal cord; consists of consulted ridges of gray matter

Question 18

Cerebral white matter

Answer 18

Deep in the cortex

Question 19

Longitudinal fissure

Answer 19

the deep groove that separates the cerebrum into right and left cerebral hemispheres

Question 20

Central sulcus

Answer 20

Separates the frontal and parietal lobes

Question 21

Precentral gyrus

Answer 21

Functional landmark; ridge of cerebral cortex anterior to the central sulcus

Question 22

Postcentral gyrus

Answer 22

Functional landmark; ridge of cerebral posterior to central sulcus

Question 23

Primary sensory areas

Answer 23

Receive sensory information and involve perceptions

Question 24

Occipital

Answer 24

Visual

Question 25

Temporal

Answer 25

Auditory

Question 26

Postcentral gyrus of parietal lobe

Answer 26

Taste

Question 27

Association

Answer 27

Perform complex integration functions

Question 28

Motor areas

Answer 28

Control voluntary skeletal muscle movements

Question 29

Primary motor areas in the precentral gyrus

Answer 29

controls general skeletal movements

Question 30

Tracts

Answer 30

Bundles of myelinated axons that act as the communications lines between the different parts of the brain

Question 31

Electroencephalogram (EGG)

Answer 31

Recording of the electrical activity in the cerebral cortex

Question 32

What are the names of all cranial nerves

Answer 32

Cerebrum, olfactory bulb, olfactory tract, pituitary gland, optic tract, PONS, MEDULLA OBLONGATA, spinal nerve C1, spinal cord, cerebellum
