Aphasia and communication Flashcards
dysphasia
Difficulty swallowing
aphasia
Inability to speak
dyslexia
Difficulty in reading
alexia
Inability to read
Aphasia is more prevalent in
Parkinson’s Disease or Muscular Dystrophy
Receptive aphasia
Primary difficulty with comprehension
Example of receptive aphasia
Wernicke’s aphasia
Expressive aphasia
Primary difficulty with expression of language
Expressive aphasia example
Broca aphasia or apraxia
Apraxia
motor programming breakdown
Dysarthria
Loss of motor control during speaking. IE chuck from psychosocial
Anterior cerebral artery supplies
frontal lobe and premotor areas. Making decisions to say something
middle cerebral artery supplies
the middle part which contains most of the language center. the middle also supplies the post central gyrus
Primary sensory cortex
simple sensory discrimination (quality and intensity) it’s a human speaking
secondary sensory cortex
recognition of sensation. What language am I hearing
Supplementary motor area
Initiation of movement, orientation of the eyes and head, and planning bimanual and sequential movements
Premotor area
Controls trunk and girdle muscles via the medial upper motor neurons
Broca’s area
Planning movements of the mouth during speech and the grammatical aspects of language. Doesn’t have to do with planning what I want to say
Correlates words when writing
Primary somatosensory cortex
Receives information from tactile and proprioceptive receptors via a three-neuron pathway
Determine location of stimulus
Understanding of shape, size, and texture of a structure
Awareness through discriminative touch and proprioception
Primary auditory cortices (PAC)
Receive information from the cochlea of both ears via a pathway that synapses in the inferior colliculus and medial geniculate body before reaching the cortex
Determines the loudness and pitch of sounds
Primary visual cortex
distinguishes shape, intensity of light, size and location of object
primary vestibular cortex
discriminates among head movements and head positions
Wernicke’s area
Comprehension of the spoken language
Interprets symbols
Secondary somatosensory cortex
stereogenesis and memory of tactile and spatial environment
