Overview Of The Nervous System Part 2

Front 1

Parietal houses functions that perceive and processes _____ events

Back 1

Somatosensory (sensation i.e. pain, temperature, touch, pressure, and proprioception)

Front 2

Parietal aka

Back 2

[Brocha's] Area 3 1 2, primary somatosensory cortex, postcentral gyrus

Front 3

parietal lobe has a ____ and ____ lobe seperated by the interparietal sulcus

Back 3

Superior and Inferior parietal lobe

Front 4

Function of the superior parietal lobule

Back 4

important in secondary and supplementary visual and somatosensory areas

Front 5

Leison at superior parietal lobe results...

Back 5

somatosensory agnosias (inability to recognize something based on touch)

Front 6

Inferior parietal lobe contains:

Back 6

- supramarginal (area 40) and Angular gyri (Area 39)

Front 7

Inferior parietal lobe is important for

Back 7

perception and interpretation of written language

Front 8

lesion to the inferior lobe results in...

Back 8

inability to interpret something that is read

Front 9

Temporal lobe contains:

Back 9

superior, middle, inferior temporal gyri with superior and inferior sulci running parallel to the sylvian fissure

Front 10

_____ is found on the superior aspect of the superior temporal gyrus

Back 10

Transverse temporal gyri of Heschl (Area 41 and 42) or primary auditory cortex

Front 11

Area 22 or ____ Area is located on the posterior part of the superior TEMPORAL gyri

Back 11

Wernicke's Area (area 22) is found on the posterior part of the superior temporal gyri.

Front 12

Lesion to Wernicke's Area results in

Back 12

impairment of comprehension and repetition, although speech remains fluent (person doesn't make sense)

Front 13

If the cingulate gyrus is cut...

Back 13

No communication between the Left and Right brain

Front 14

The septum pellucidum...

Back 14

forms the medial walls of the lateral ventricles

Front 15

the Fornix is...

Back 15

the major fiber system arising from the hippocampal formation

Front 16

Diencephalon lies below the ___

Back 16

fornix

Front 17

Diencephalon has two parts:

Back 17

- Thalamus
- Hypothalamus

Front 18

Thalamus serves as:

Back 18

Relay center, all sensory information must stop here

Front 19

Hypothalmus serves to

Back 19

regulate a host of visceral functions, such as temperature, endocrine functions, and feeding, drinking, and emotional, and sexual behaviors

Front 20

Olfactory bulb function:

Back 20

receives info from olfactory cranial nerve I and gives rise to the olfactory tract

Front 21

Cerebrospinal fluid (CSF) is synthesized by:

Back 21

Choroid plexus (epithelial cells) mainly in lateral ventricle

Front 22

Lateral ventricle originates from

Back 22

prosencephalon -- telencephalon

Front 23

Basal ganglia crucial in

Back 23

motor integration processes

Front 24

Structures of basal ganglia (3)

Back 24

- Caudate nucleus
- putamen
- globus pallidus

Front 25

Limbic system has important functions in regulation of:

Back 25

- emotional behavior
- short-term memory processes
and control of autonomic, other visceral and hormonal functions

Front 26

Amygdala (limbic system):

Back 26

- responsible for learned fear

Front 27

Hippocampus (limbic system):

Back 27

- responsible for memory storage -- if damaged only have long term memory that existed prior to damage

Front 28

Cerebellum important in:

Back 28

regulation and coordination of fine motor movement (such as picking up a pin)

Front 29

Cerebellum is attached to brain stem by:

Back 29

cerebellar peduncles

Front 30

cerebellum is also known as

Back 30

little cerebrum

Front 31

The cerebellum has 3 lobes per hemisphere:

Back 31

- Flocculonodular
- Anterior lobe
- posterior lobe

Front 32

the flocculonodular lobe of the cerebellum:

Back 32

is the smallest, receives vestibular input --if off causes trouble with balance (CN 8)

Front 33

posterior lobe of the cerebellum:

Back 33

largest lobe, receives spinal input

Front 34

anterior lobe or the cerebellum:

Back 34

towards the midline, recieves cortical input

Front 35

Brainstem looks like:

Back 35

4 breasted woman

Front 36

Gracile and cuneate tubercle:

Back 36

contain relay and integrating neurons associated with ascending sensory fibers from the periphery to the medulla.

Front 37

pons has 2 parts:

Back 37

- Dorsal half (tegentum)
- Ventral half (basilar regio)
