A

sagittal, coronal, horizontal

24
Q

What direction does the sagittal plane divide the brain?

A

divides the brain vertically into the left and right portions

Q

What direction does the coronal plane divide the brain?

A

runs up and down from a side view to create the front and back portions

28
