Question

The incorrectly matched pair is

• A. Cerebral aqueduct - canal that passes through midbrain
• B. Corpora quadrigemina - four rounded swellings present on ventral portion of midbrain
• C. Cerebrum - Very convoluted surface
• D. Medulla oblongata - controls gastric secretions.

Answer 1

The correct option is A Cerebral aqueduct - canal that passes through midbrain

1. The canal that passes through midbrain - canal aqueduct
   
2. The corpora quadrigemina are the four colliculi—two inferior, two superior—located on the tectum of the dorsal aspect of the midbrain.
   
3. The cerebral cortex of the human brain is highly convoluted, meaning it has many folds and creases.
   
4. 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'
