Question

The brainstem is made up of______

Answer 1

Brainstem:

1. The brainstem is the part of the brain that connects to the spinal cord directly.
2. It has areas that manage breathing and heart rate.
3. It is a communication route between the brain and the spinal cord.
4. The brainstem gives rise to the cranial nerves, which control movement and sensation in and around the face.

Parts of the brainstem:

Midbrain:

1. Between the pons and the diencephalon, the midbrain functions as a link.
2. The superior cerebellar peduncles connect it to the cerebellum in the back.
3. The cerebra are placed in the anterior region of the midbrain, with the interpeduncular fossa lying between them.

Pons:

1. The pons connects the medulla oblongata to the midbrain superiorly and the medulla oblongata to the medulla oblongata inferiorly.
2. When looking at the brainstem from the front, the front section of the pons is convex and can be seen as a noticeable distention.
3. The basilar groove, which is where the basilar artery lies, is located on the surface of the anterior distention.

Medulla oblongata:

1. The medulla oblongata connects the pons to the spinal cord and is the most inferior part of the midbrain.
2. At the level of the foramen magnum, it meets the spinal cord.
3. The pyramids are found in the medulla oblongata's anterior section.
4. Motor fibers travel from the precentral gyrus, or motor cortex, to the grey matter of the spinal cord, where they synapse and travel to the body's muscles via the peripheral nervous system.

Final answer: The brainstem is made up of the midbrain, pons, and medulla oblongata.
