14) The correct option is B. pons.
The part of the brain, which connects the medulla to the midbrain is the pons. The midbrain is the short portion of the brain stem between the pons and the cerebral hemispheres.
15) The correct option is C. midbrain.
The nuclei of cranial nerves III and IV are present in the midbrain. Midbrain includes the red nuclei, the substantia nigra and the nuclei of cranial nerves III and IV.
16) The correct option is A. basal nuclei.
The substantia nigra interconnects with the basal nuclei. It is a basal ganglia structure present in the midbrain, which plays an essential role in reward and movement.
17) The correct option is B. photoreceptors.
Vision is dependent upon photoreceptors. Photoreceptors are special cells in the retina, which are responsible for converting light into signals that send to the brain.
