What is aphasia?
A language disorder that affects a person’s ability to communicate.
What is non fluent aphasia or damage to Broca’s area?
People with this pattern of aphasia struggle to get words out, speak in very short sentences and omit words.
Damage to Wernicke’s area causes
Aphasia
Wernicke’s area is responsible for
comprehension of speech
Broca’s area is responsible for
the production of speech
The primary visual cortex is located in the
occipital lobe
The primary somatosensory cortex is located in the
parietal lobe of the brain
The lateral fissure separates which two lobes?
The temporal and frontal lobe
function of the arcuate fasciculus
connecting Broca’s and Wernicke’s areas, which are involved in producing and understanding language
lesion on the left primary motor cortex
Difficulty with movement of the right arm - specifically, spastic paralysis
lesion on the left primary sensory cortex
no sensation from X region
lesion on the primary auditory cortex
Deafness - loss of hearing
lesion on the supramarginal and angular gyrus
Inability to understand reading and writing
damage to lower motor neurons
produces flaccid paralysis of muscles on the same side of the body. muscle tone is decreased or lost. no voluntary movement or reflux action
damage to upper motor neurons in the cerebral cortex
removes inhibitory influences that some of the neurons have on lower motor neurons, which causes spastic paralysis of muscles on the opposite side of the body
flaccid paralysis
Flaccid paralysis causes your muscles to shrink and become flabby. It results in muscle weakness.
Spastic paralysis
Spastic paralysis involves tight and hard muscles. It can cause your muscles to twitch uncontrollably, or spasm.
damage to the cerebellum would result in
uncoordinated movements
