Question

Which of the following pairs of terms identify spaces that are roughly PERPENDICULAR (at right angles to one another) in the human brain (give or take 30 degrees or so)?


temporal horn of the lateral ventricle and cerebral aqueduct

temporal horn of the lateral ventricle and central part (“body”) of the lateral ventricle

precentral sulcus and postcentral sulcus

inferior frontal sulcus and inferior temporal sulcus

central sulcus and the parieto-occipital sulcus

superior frontal sulcus and inferior frontal sulcus

Answer 1

Answer:

The correct option is;

Temporal horn of the lateral ventricle and the cerebral aqueduct

Explanation:

The temporal horn, of lateral ventricle, that is  is located in the temporal lobe below the frontal and third ventricle and it is positioned sideways flat with a slight inclination while the cerebral aqueduct traverses from the mid-brain which is closer to the to the crossing approximately perpendicularly in between the temporal horn of the lateral ventricle to the fourth ventricle which (the fourth ventricle) continues on to the central canal of the spinal cord.

Answer 2

The temporal horn of the lateral ventricles and cerebral aqueduct
