Lab Flashcards
What is the function of the post central gyrus?
Primary somatosensory association area.
What is the function of the superior parietal lobule?
Complex functions of body awareness and orientation.
Ex: Damage here may lead to patients forgetting to dress part of their body (contralateral limb) or get lost easily. Lose spatial awareness.
What is the function of the inferior partial lobule?
This region is associated with complex visual functions. Dominant lobe else associated with language. This may include part of Wernickes area (in the supra marginal gyrus). Damage here effects ability to read.
What is the function of Heschl’s gyrus?
Primary sensory cortex for hearing. Since info from both ears is processed bilaterally, damage to this area in only one hemisphere may cause only minor deficits. Damage here in both hemispheres may result in an inability to understand spoken language.
What is the function of the superior gyrus?
Associated with vision, especially visual memory and perception.
What is the function of the pre central gyrus?
Primary motor cortex, which controls voluntary movements. Damage here would lead to weakness and movement deficits in the OPPOSITE SIDE OF THE BODY.
What is the function of the superior and middle frontal gyri?
This region includes secondary motor and premotor areas which organize voluntary movements, including eye movements.
What is the function of the inferior frontal gyrus (posterior portion)?
Called Broca’s area in the dominant hemisphere and is needed for programming speech. Damage results in difficulties speaking, but not understanding language.
What is the function of the prefrontal cortex?
Makes up a person’s personality. Associated with the planning of sequencing and complex tasks. Damage may change personality or lead to compulsive/repetitive behaviors.
What makes up the prefrontal cortex?
Superior, middle, inferior gyri.
What is the function of the Amygdala?
Part of limbic system. Plays a role in fear, behavior and emotion. Monkeys with removed amygdala’s have been shown to have a lack of fear or inhibition. Formation of strongly emotional memories.
Where is the Amygdala located?
In the temporal lobe. Deep and inferiorish.
What is the function of the basal ganglia?
Forms the a loop with the cortex and thalamus to facilitate smooth movements by inhibiting competing movements.
What is the function of the cerebellum?
Coordinate planned movement being sent efferently. Maintains balance.
What is the function of the pons?
Bridge between spine and brain for both afferent and efferent fibers.
What is the function of the medulla?
Thus, the medulla is essential to our survival because it ensures vital systems like the cardiovascular and respiratory systems are working properly. Additionally, the medulla is responsible for a number of reflexive actions, including vomiting, swallowing, coughing, and sneezing. Several cranial nerves also exit the brainstem at the level of the medulla.
Where are cranial nerves 1 and 2 located?
The forebrain.
