Motor Cortex Areas Of The Brain Flashcards
What does the frontal lobe have a role in
Cognition emotional regulation executive functioning expressive language short-term memory
What does the Temporal lobe have a role in
Auditory
comprehension of language
long-term memory
What does the parietal lobe have a role in
Perception
sensory detection
integration of visual
somatosensory
What does the occipital lobe have a role in
Vision
What are the motor cortex areas
The primary motor cortex premotor cortex: supplemental motor cortex Frontal eye field Broca's area prefrontal cortex
What does the primary motor cortex area do
actual execution of voluntary movement
Where does the primary motor cortex area produce movement
On the contralateral side when stimulated
What does the primary motor cortex area respond to
Proprioceptive and cutaneous input
What do lesions in the primary motor cortex area result in
Contralateral paresis
decreased fine motor
What is the premotor cortex area involved in
Sequenced patterned movements
Orientation of movement
anticipation of movement based on external cues
Where does the premotor cortex area produce movement
Bilateral movement of axial proximal distal and facial movements
What do lesions in the premotor cortex area result in
Apraxia
perseveration
What does the supplementary motor cortex area do
It’s active before movement occurs
responsible for preparation or initiation of the moment
works in sequencing (planning) goal directed movements
involved with more complex programmed motor acts
procedural memory
What does the association area do
Processes visual and auditory cues is relevant and send all the information to the primary motor cortex area
What does a lesion on the supplementary motor cortex area result in
Akinesia
decreased initiation of movement
apraxia
Perseveration
