A&p 1 Chapters 11 And 12

Front 1

Primary motor cortex

Back 1

In precentral gyrus, pyramidal cells allow us to consciously control precise voluntary movements of skeletal muscles

Front 2

Premotor cortex

Back 2

anterior to precentral gyrus, helps plan movements such as typing, staging area for skilled motor activities

Front 3

Broca's area

Back 3

anterior to inferior region of premotor area, motor speech area

Front 4

Frontal eye field

Back 4

partially in and inferior to premotor cortex and superior to broca's area. Controls voluntary movement of eyes

Front 5

primary somatosensory cortex

Back 5

in postcentral gyrus of parietal lobe, identify body region being stimulated (spacial discrimination)

Front 6

somatosensory association cortex

Back 6

posterior to primary somatosensory cortex, integrate sensory inputs, relay it to primary so it can produce an understanding of an object being felt.

Front 7

primary visual cortex

Back 7

extreme posterior tip of occipital lobe, recieves visual info from retina

Front 8

visual association area

Back 8

uses past visual experiences to interpret visual stimuli

Front 9

primary auditory cortex

Back 9

superior portion of temporal lobe abutting the lateral sulcus, interprets pitch, loudness, and location of sounds

Front 10

multimodal association cortex

Back 10

It allows us to tie information that we receive to previous experience and knowledge, and then helps us decide what action to take.

Front 11

medulla oblongata

Back 11

autonomic reflex center of the brain

Front 12

pyramidal cells

Back 12

allow us to control our skeletal muscles

Front 13

second-order neurons

Back 13

Second-order neuron cell bodies reside in the dorsal horn of the spinal cord, transmit impulses to thalamus

Front 14

third- order neurons

Back 14

cell bodies in thalamus, impulses to somatosensory cortex of cerebellum

Front 15

first-order neurons

Back 15

cell bodies in ganglion,/ dorsal root or cranial. impulses from cutaneous skin receptors and from proprioreceptors to spinal cord and brain stem

Front 16

condition that results from viral destruction of ventral horn motor neurons

Back 16

poliomyelitis

Front 17

anencephaly

Back 17

cerebrum and part of the brain stem never develop

Front 18

What is located in the lateral horn of the spinal cord grey matter?

Back 18

visceral motor soma

Front 19

Transection of the spinal cord at T3 results in

Back 19

paraplegia

Front 20

beta waves

Back 20

concentrating when solving a problem

Front 21

what part of the brain produces dopamine

Back 21

substantia nigra

Front 22

Which part of the cerebellum is involved in planning, rather that executing, movement?

Back 22

the lateral part of each hemisphere

Front 23

In which of the following areas does sorting and editing of sensory impulses take place?

Back 23

thalamic nuclei

Front 24

Which of the following is the central layer of the meninges?

Back 24

arachnoid mater

Front 25

The CNS starts differentiating from the neural tube in the developing embryo after week __________.

Back 25

four

Front 26

In which part of the cerebral cortex do sensations, emotions, and thoughts come together and make us who we are?

Back 26

the multimodal association areas

Front 27

Which of the following neurotransmitters is thought to prime the prefrontal cortex and the medial temporal lobes to form memories?

Back 27

acH

Front 28

Acting as an excitotoxin, the main culprit in the damage caused by a cerebral vascular accident (CVA) is

Back 28

glutamate

Front 29

fornix

Back 29

link limbic systems together
