Surface anatomy, cerebral cortex and basal ganglia Flashcards
What lobe would you find broca’s area?
Frontal lobe
What lobe would you find Wernicke’s area?
Temporal lobe
Where would you find the motor cortex?
Pre central gyrus
Where would you find the somatosensory cortex?
Post central gyrus
Where would you find the insula?
Deep within the later sulcus
Role of Wernicke’s area?
Language comprehension
Role of Broca’s area?
Language production
Cingulate gyrus: location and function
Surrounds corpus callosum.
Part of limbic system (emotion/behaviour)
Fornix: location and function
Surrounds hippocampus.
Carries afferent fibres from diencepohalon and basal ganglia to hippocampus.
Optic chaism:
Located under hypothalamus. Where optic nerves from retina cross in brain.
Mammilary bodies: location and function
Posterior to optic chaism.
Memory
Pineal gland: location and function
Posterior to thalamus.
Produces melatonin (circadian rhythm)
Pituitary gland: location and function
Below hypothalamus. (Look like ballsack)
Hormones
Hippocampus
Memory
Amygdala
Emotions
