Myelencephalon

The Myelencephalon (pronounced: my·el·en·ceph·a·lon) is a significant part of the brainstem that plays a crucial role in the human nervous system.

Etymology

The term "Myelencephalon" is derived from the Greek words 'myelos' meaning marrow and 'encephalon' meaning brain.

Function

The Myelencephalon, also known as the medulla oblongata, is responsible for various autonomic functions. These include, but are not limited to, controlling and regulating heart rate, blood pressure, and respiration. It also plays a role in reflex actions such as swallowing, sneezing, and coughing.

Structure

The Myelencephalon is the most inferior part of the brainstem, located between the pons and the spinal cord. It contains various nerve tracts that carry signals between the brain and the rest of the body.
