Primary motor cortex |
In precentral gyrus, pyramidal cells allow us to consciously control precise voluntary movements of skeletal muscles |
|
Premotor cortex |
anterior to precentral gyrus, helps plan movements such as typing, staging area for skilled motor activities |
|
Broca's area |
anterior to inferior region of premotor area, motor speech area |
|
Frontal eye field |
partially in and inferior to premotor cortex and superior to broca's area. Controls voluntary movement of eyes |
|
primary somatosensory cortex |
in postcentral gyrus of parietal lobe, identify body region being stimulated (spacial discrimination) |
|
somatosensory association cortex |
posterior to primary somatosensory cortex, integrate sensory inputs, relay it to primary so it can produce an understanding of an object being felt. |
|
primary visual cortex |
extreme posterior tip of occipital lobe, recieves visual info from retina |
|
visual association area |
uses past visual experiences to interpret visual stimuli |
|
primary auditory cortex |
superior portion of temporal lobe abutting the lateral sulcus, interprets pitch, loudness, and location of sounds
|
|
multimodal association cortex |
It allows us to tie information that we receive to previous experience and knowledge, and then helps us decide what action to take. |
|
medulla oblongata |
autonomic reflex center of the brain |
|
pyramidal cells |
allow us to control our skeletal muscles |
|
second-order neurons |
Second-order neuron cell bodies reside in the dorsal horn of the spinal cord, transmit impulses to thalamus |
|
third- order neurons |
cell bodies in thalamus, impulses to somatosensory cortex of cerebellum |
|
first-order neurons |
cell bodies in ganglion,/ dorsal root or cranial. impulses from cutaneous skin receptors and from proprioreceptors to spinal cord and brain stem |
|
condition that results from viral destruction of ventral horn motor neurons |
poliomyelitis |
|
anencephaly |
cerebrum and part of the brain stem never develop |
|
What is located in the lateral horn of the spinal cord grey matter? |
visceral motor soma |
|
Transection of the spinal cord at T3 results in |
paraplegia |
|
beta waves |
concentrating when solving a problem |
|
what part of the brain produces dopamine |
substantia nigra |
|
Which part of the cerebellum is involved in planning, rather that executing, movement? |
the lateral part of each hemisphere |
|
In which of the following areas does sorting and editing of sensory impulses take place? |
thalamic nuclei |
|
Which of the following is the central layer of the meninges? |
arachnoid mater |
|
The CNS starts differentiating from the neural tube in the developing embryo after week __________. |
four |
|
In which part of the cerebral cortex do sensations, emotions, and thoughts come together and make us who we are? |
the multimodal association areas |
|
Which of the following neurotransmitters is thought to prime the prefrontal cortex and the medial temporal lobes to form memories? |
acH |
|
Acting as an excitotoxin, the main culprit in the damage caused by a cerebral vascular accident (CVA) is |
glutamate |
|
fornix |
link limbic systems together |
