Neuroanatomy Quiz #2 Flashcards
What function(s) does the inferior frontal gyrus serve?
The left area of the inferior frontal gyrus is responsible for expressive language function.
What function(s) does the middle frontal gyrus serve?
There is some evidence that it plays a role in executive mechanisms (e.g., sustained attention and working memory)
What function(s) does the superior frontal gyrus serve?
A specialized region of the superior frontal gyrus is responsible for expressive language (both spoken and written word).
What function(s) does the precentral gyrus serve?
Somatic motor control
What function(s) does the central sulcus serve?
It functions as a dividing line between the parietal lobe and the frontal lobe. The central sulcus also separates the primary somatosensory cortex from the primary motor cortex.
NOTE: The central sulcus is also called the central fissure and it used to be called the fissure of Rolando!
What function(s) does the supramarginal gyrus serve?
Receptive language function
Wiki says: Likely to be related to language function and processing
What function(s) do the frontal eye fields (FEF) serve?
Non-tracking, voluntary eye movements.
Destruction to FEF causes deviation of the eyes to the ipsilateral side
What function(s) does the primary motor cortex serve?
Movement.
NOTE: The primary motor cortex demonstrates contralateral topographic localization of specific regions of the body (i.e.,)
What function(s) does the premotor cortex serve?
Wiki says: The functions of the premotor cortex are diverse and not fully understood. It projects directly to the spinal cord and therefore may play a role in the direct control of behavior, with a relative emphasis on the trunk muscles of the body. It may also play a role in planning movement, in the spatial guidance of movement, in the sensory guidance of movement, in understanding the actions of others, and in using abstract rules to perform specific tasks. Different subregions of the premotor cortex have different properties and presumably emphasize different functions.
What function(s) does the primary somatosensory cortex serve?
It is the main sensory receptive area for the sense of touch.
NOTE: The primary somatosensory cortex demonstrates contralateral topographic localization of specific regions of the body (i.e., ___).
What function(s) does the primary auditory cortex serve?
It processes auditory information in humans and other vertebrates. It is a part of the auditory system, performing basic and higher functions in hearing.
What function(s) does the superior parietal lobule serve?
One of the primary areas of body or spatial awareness.
What is the primary visual cortex (V1)?
V1 is the part of the neocortex that receives and processes visual input from the retina. The left hemisphere visual cortex receives signals from the right visual field and the right visual cortex from the left visual field.
It transmits the information along the dorsal and ventral streams (or pathways). Other names for these pathways are the “where” pathway (or M-pathway) and the “what” pathway (or P-pathway), respectively.
What is the visual association cortex?
Receives information from the primary visual cortex. It serves to help understand more complex visual information.
