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
