The Brain Structure

Introduction

The brain floats to protect against outside influences in the cerebrospinal fluid. Enclosed in the brain are three layers of protective membranes that envelop the spinal cord of the central nervous system. The brain itself contains approximately 10 to 10 people in nerve cells, which in turn owns all of the connections to about 8 to 10 thousand other neurons. This is an incredibly high number of connections of neurons with each other. Amazingly, however, to operate its functions, the brain requires extremely low energy of about 15 to 20 watts. This is the power of a small light bulb.

Myelencephalon

Myelencephalon, also known as the medulla oblongata, is part of the brain that is similar to the spinal cord in structure. It is the shape of a truncated cone measuring about 25 mm. The edge of the medulla oblongata on the ventral surface coincides with the bottom edge. The structure of the Myelencephalon is isolated by four surfaces: the ventral, dorsal and 2 lateral. There are visible grooves on the surface of Myelencephalon, which are the continuation of the spinal cord fissures (Seymour, 2000).

On the ventral surface of the front side of the median gap is pair formation, which looks like a pyramid. This pyramid represents the border between medulla and spinal cord, which is projected on the edge of the foramen magnum. Lateral to the pyramid, in front of the Myelencephalon are groove separating the oval elevations on the surface of the Myelencephalon. The dorsal surface also has a number of formations (White, Southgate, Thomson & Brenner, 1986). The structure of Myelencephalon is very complex and it seems that everything is packed up within the Myelencephalon. However, the formation of grooves and lobes makes space for a lot of other brain features ...
