Answer 2

Answer:

19. The canal that passes through midbrain - canal aqueduct

The corpora quadrigemina are the four colliculi—two inferior, two superior—located on the tectum of the dorsal aspect of the midbrain.

The cerebral cortex of the human brain is highly convoluted, meaning it has many folds and creases.

The medulla oblongata controls gastric secretion both by the parasympathetic branch of the nervous system and the endocrine system.

Hence, the correct answer is 'Cerebral aqueduct - canal that passes through midbrain'

20. The brain stem is a bundle of nerve tissue at the base of the brain. It connects the cerebrum and cerebellum to the spinal cord.
