Anatomy of Brain Flashcards
most anterior region
frontal
lies between the frontal and occipital lobes
Parietal
posterior region, visual processing
Occipital
lateral region, auditory processing
Temporal
contains more cell bodies and dendrites, which lack myelin
Gray Matter
consists mostly of axons with white myelin sheaths
White Matter
boundary of the temporal lobe
Sylvian Fissure
divides the frontal lobe from the parietal lobe
Central Sulcus
a bundle of axons that connects the two cerebral hemispheres
Corpus Callosum
a strip of cortex behind the central cortex, important for touch
Postcentral Gyrus
in the frontal lobe, important for motor control
Precentral Gyrus
bisects the brain into right and left halves
Sagittal Plane
divides the brain into front (anterior) and back (posterior) regions
Coronal Plane
divides the brain into an upper and lower part
Horizontal Plane
the back portion of the body
Dorsal
the front part of the body
ventral
the front side of the body
Anterior
the back of the body
Posterior
toward the head end of the body; upper
Superior
away from the head; lower
Inferior
nearer to the center (trunk of the body) or to the point of attachment to the body
Proximal
sites located away from a specific area, most often the center of the body
the hand is distal to the shoulder. The thumb is distal to the wrist
distal
on the side opposite to another structure
the right arm and leg are controlled by the left, contralateral, side of the brain
Contralateral
