• gray commisure connects the anterior and posterior horns

• central canal is located within the white matter

• all of the aforementioned is correct

• none of the aforementioned is correct

Identify the CORRECT statement regarding the structures of the hindbrain

• medulla comnects the pons superiorly to spinal cord inferiorly

• medulla serves as a conduit for ascending and descending nerve fibers

• pons is located on the anterior surface of the cerebellum

• pons contains transverse fibers that connect the two cerebral hemispheres

• all of the above is correct

Identify the INCORRECT statement regarding the midbrain

• contains many nuclei

• connects forebrain to the hindbrain

• contains cerebral aqueduct

• forms part of the dienecephalon

• narrow part of the brain

Identify the INCORRET statement regarding the cerebrum

• cortex is highly folded

• lobes of the brain are named according the bones of cranium under which they lie

• sulci are the grooves located between gyri
