• B. medulla
• C. pons
• D. cerebrum

Answer 1

The correct option is B

medulla

The correct option is B.

The explanation for the correct option:

1. The cerebrum, diencephalon (which includes the thalamus and hypothalamus), cerebellum, and brain stem are all parts of the brain (midbrain, pons, and medulla oblongata).
2. The base of the brain stem is known as the medulla oblongata.
3. The spinal cord is a bundle of nerves that starts in the medulla at the base of the skull and runs through the lumbar area of the vertebral column to the medulla oblongata.
4. The medulla oblongata connects the brain and the spinal cord, and the medulla is where the spinal cord begins.

Final answer: Spinal cord originates from the medulla.
