Gross Anatomy of the Brain and Spinal Cord 1 Flashcards
what is normally the dominant hemisphere
left hemisphere
what is the left hemisphere responsible for
language, speech and writing
what are the left and right hemispheres connected by
corpus callosum
what is the non-dominant hemisphere in control of
orientation of the body in its environment, visual, interpretation of music, emotion and intuition
what is the purpose of the sulci
they are grooves that separate the gyri
what is the purpose of the gyri
ridges that increase surface area
what divides the brain into quarters
longitudinal cerebral fissure and the central sulcus
what divides left and right hemispheres
longitudinal fissure
what runs in the longitudinal fissure
falx cerebri
what are the ridges in the cerebellum called
folia
what cranial nerves are associated with medulla
CN IX, X, XII
what cranial nerves are associated with the pons
CN VI-VIII
what is part of the diencephalon
epithalamus, thalamus, hypothalamus
what surface is the parietal-occipital sulcus visible on
medial surface
what sulcus is the insula deep to
the lateral sulcus
what are the three major parts of the frontal lobe
prefrontal cortex
motor cortex
broca’s area
what is the function of the prefrontal cortex
problem solving
personality
what is the function of the motor cortex
planning, control and voluntary movement via
primary motor cortex
what is the function of Broca’s area
production of speech
usually found in left hemisphere
what is broca’s aphasia
when there has been damage to broca’s area and sounds can be made but words cannot be formed, also an inability with writing
what are the main parts of the parietal lobe
primary somatosensory cortex
posterior parietal cortex
what is in the primary somatosensory cortex
sensory humunculus and deals with tactile sensation
what is the function posterior parietal cortex
spatial perception
spatial attention
cognitive functions
what is the main part of the occipital lobe
primary visual cortex
