7th 328-377 neuro A Flashcards
What are sulci?
Grooves/depressions between gyri.
What sulcus separates the temporal lobe from the frontal and parietal lobe?
The lateral sulcus (sylvian fissure).
Define insula.
A portion of cerebral cortex folded deep in the lateral sulcus; forms the floor of the lateral sulcus.
What is the function of Broca’s area?
Language production.
Within what lobe is Wernicke’s area located?
The dominant (usually left) temporal lobe.
What is the function of Wernicke’s area?
It is involved in the comprehension of written and spoken language.
What are the functions of the frontal lobes?
Motor function, problem solving, judgement, personality, social and sexual behaviour.
Where is the primary somatosensory cortex located?
In the post-central gyrus of the parietal lobe.
What are the functions of the parietal lobes?
SOMATOSENSORY function. The dominant lobe is involved in perception, interpretation of sensory information, language and mathematical operations. The non dominant lobe has visiospatial functions.
What are the motor and sensory homunculi?
Proportional somatotopical representations of how much of the cortex innervates certain body parts.
How many horns does the lateral ventricle have and what are they called?
3 horns.
Anterior, posterior and inferior.
What is the foramen between the lateral ventricles and 3rd ventricle called?
The foramen of Munro.
What is the foramen between the 3rd and 4th ventricle called?
The cerebral aqueduct.
What are the foramen called that connect the 4th ventricle to the subarachnoid space?
The foramina of luschka (lateral) and the foramen of magendie (medial).
Where is choroid plexus located?
Along the choroid fissure of the lateral ventricle and in the roof of the 3rd and 4th ventricle.
