Question

Quizplus · Accepted Answer

The rostral end of the neural tube at 28 days will eventually form the three interconnected ventricular spaces in the brain, known as the lateral, third, and fourth ventricles. Therefore, the correct option is E. Option A (telencephalon) refers to the two cerebral hemispheres of the brain that develop from the forebrain. Option B (cerebral cortex) is the outer layer of the brain, derived from the telencephalon, and responsible for conscious thought, movement, sensation, and perception. Option C (mesencephalon) is the midbrain, which includes sensory and motor pathways connecting the brainstem and forebrain, and option D (myelencephalon) refers to the medulla oblongata, which extends from the brainstem to the spinal cord and contains many vital centers for cardiac and respiratory functions.
