Module 5 Flashcards
Association areas
What is the primary sensory cortex responsible for?
Identifies where the sense came from and what the sense is.
What is the primary motor cortex responsible for?
It triggers and executes movement commands. It generates movement and activates the correct muscles.
What is the function of the unimodal association cortex?
It is responsible for the processing of higher level processing for one modality. It is located in areas adjacent to the primary cortex, and only processes information specific to a primary cortex.
What is the function of the heteromodal association cortex?
It integrates many sensory modalities from multiple sources and functions.
What is the function of the premotor cortex?
It is responsible for stimulation of multiple joints of the same limb, and the preparation of voluntary movements.
i.e. the ‘set’ part of ‘ready, set, go’
What is the function of the supplementary motor area?
It is involved in the planning and execution of complex movements and bilateral coordination of movements. It has direct influence on proximal muscles, and slight influence on distal muscles.
What is apraxia?
The inability to perform complex acts requiring sequences of muscle contractions or a planned strategy.
What is the function of the somatosensory association cortex?
It gives meaning to the sensation.
What is agnosia?
A loss of knowledge or understanding.
i.e. astereognosis: unable to process what objects are by touch
