Question

write the short note on small medulla oblongata​

Answer 1

The medulla oblongata or simply medulla is a long stem-like structure which makes up the lower part of the brainstem. It is anterior and partially inferior to the cerebellum. It is a cone-shaped neuronal mass responsible for autonomic functions, ranging from vomiting to sneezing.

Answer 2

___________________________

The midline of the medulla is the anterior median fissure, which is continuous along the length of the spinal cord.

However, it is interrupted temporarily by the decussation of the pyramids .As we move away from the midline, two sulci are visible – the ventrolateral sulcus and the posterolateral sulcus.

The pyramids are paired swellings found between the anterior median fissure and the ventrolateral sulcus. Information on the pyramids can be found here.

The olives are another pair of swellings located laterally to the pyramids – between the ventrolateral and posterolateral sulci.
