Flashcards in Quiz 2 Appendix B Deck (36):
1

Brain Stem includes:

Medulla Oblongata
Pons
Midbrain

2

Vital for life-maintaining functions as breathing & cardiovascular control.

Medulla Oblongata

3

Although small the ________ _________ contains ALL ascending & descending neuron fibers associated w/ the spinal cord

Medulla Oblongata

4

Located superior to the M.O. & has a distinct ventral bulge

Pons

5

Cranial Nerve pair V (trigeminal) appears dramatically on its lateral surface

Pons

6

Both form the ventral wall (floor) of the 4th brain ventricle

Pons and M.O

7

Well adapted as an integration & relay center between the cerebrum & cerebellum

Pons

8

Small area immediately surrounding the cerebral aqueduct

Midbrain

9

Distinct passageway for cerebrospinal fluid between the 3rd & 4th ventricles

Cerebral Aqueduct

10

Posterior to the aqueduct is collectively called the ______. Has many parts including the 2 superior & inferior colliculi

Tectum

11

Ventral to the aqueduct are bilateral bulges called the ______ ______

Cerebral peduncles

12

Important red & black nuclei make up a part of each peduncle. This same area is called the ____

Crus

13

Coordinates subtle reflexes dealing w/ head movements in seeing & hearing.

Midbrain

14

Full of important descending motor oriented fibers

Cerebral peduncles

15

_________ is found in the 3rd ventricle

Diencephalon

16

The ________ _________ is simply a fluid filled space bounded by the Thalamus & hypothalamus laterally

Third ventricle

17

The __________ is a neuron relay center as well as having control over many *autonomic* & *endocrine* functions

Diencephalon

18

Largest lobes (about 35% of the cerebrum)

Frontal lobes (Rt. and Lt.)

19

The frontal lobe is separated from the parietal lobe by the:

Central sulcus

20

The frontal lobe is separated from the temporal lobe by the:

Lateral sulcus (Sylvian sulcus)

21

Our frontal lobes are beat known for their role as both "thought elaborating" centers and as:

Voluntary motor initiating centers

22

The corpus callosum is full of neuron axons that connect rt. & lt. cerebral hemispheres. Such structures connecting equivalent halves of the CNS are often termed _____________

Commissures

23

These lobes are sandwiched between each of the other lobes

Parietal lobes

24

They include a post central gyrus, superior & inferior parietal lobules. The inferior parietal lobule is primnarily made up of the supramarginal & angular gyri

Parietal lobes

25

Within this lobe one "feels" such modalities as light touch, deep touch (pressure), pain, temp. changes & kinesthetic input

Parietal lobe

26

In this lobe you are also able to associate many inputs from other lobes in order to develop skills such as reading & writing

Parietal lobe

27

These are small lobes with indistinct lateral & inferior boundaries

Occipital lobes (rt. and lt.)

28

Sight & memory of past sight experience are received, built up, stored, & associated here:

Occipital lobes

29

Like the frontal lobes the ________ lobes are subdivided into distinct superior, middle, & inferior temporal gyri

Temporal lobes

30

Auditory reception, interpretation & memory center are some functions of this lobe:

Temporal lobe

31

Much of our behavior control mechanism s tied up along the medially located hippocampal formation of this lobe:

Temporal lobe

32

The _____ is a significant olfactory interpretation area

Uncus

33

Posterior enlargement just dorsal to the pons & medulla

Cerebellum

34

Embryologically it is apart of the hindbrain (rhombencephalon) along with the medulla oblongata & pons.

Cerebellum

35

The fluid filled space between the pons, medulla, & the cerebellum is known as the:

4th ventricle

36

Plays a major role in maintaining muscle tone & in seeing that our voluntary movements are effective

Cerebellum (Does not initiate gross movements but aids in making them smooth & harmonious)
