Surface anatomy, cerebral cortex and basal ganglia Flashcards
(24 cards)
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
Corpus callosum
Laterlisation
Putamen
Makes up corpus striatum.
Movement of limbs
Globus pallidus
Makes up corpus striatum
Regulation of voluntary movement
Caudate nucleus
Makes up corpus striatum
Internal capsule
Space b/t thalamus and caudate.
Connects the cerebral cortex with subcortical structures.
Thalamus
Relay centre
Hypothlamus
Hormones/Homeostasis
Medial geniculate nuclei (MGN)
Auditory part of the thalamus.
Relays inf. colliculus to auditory cortex.
Lateral Geniculate Nuclei (LGN)
Visual part of the thalamus.
Optic nerve to the occipital lobe
