Anatomy - Lab 5 Flashcards
Where is the primary motor cortex found?
Precentral gyrus
Where is the primary somatosensory cortex found?
Postcentral gyrus
What is found on the inferior frontal gyrus?
Broca’s area (left hemisphere) = speech
What is the function of the angular gyrus?
Interpretation of language (especially written)
What is the transverse temporal gyrus and where is it found?
Primary auditory cortex
Found within the lateral sulcus
Where is the insula lobe found?
Found within the depths of lateral sulcus
Occlusion of which artery would result in loss or aberrant speech and language function?
Middle cerebral artery (MCA)
Where is the primary visual cortex found?
Lies on the gyri of either side of the calcarine sulcus
What forms the paracentral lobule?
Found on the medial side
Formed by the precentral gyrus, central sulcus and postcentral gyrus
The paracentral lobule has upper motor neurons for which parts of the body?
Lower extremity
The paracentral lobule receives sensory info from which parts of the body?
Lower extremity and genitals
Occlusion of which cerebral artery would result in loss of primary visual cortex activity?
Posterior cerebral artery
Occlusion of which cerebral artery would result in loss of ability to wiggle toes?
Anterior cerebral artery
Where is the primary olfactory cortex found?
Uncus
Where is the anterior perforated substance found?
Area underlying origin of MCA
Perforated by many small blood vessels
