We divide the brain into different parts to try to better understand how it works and how it develops, one is the rhombencephalus, a region that originates in the primary embryonic caudal gallbladder.
When we talk about rhombncephalus we mean the posterior brain, it is the structure that, throughout its development, will give rise to different substructures, responsible for fulfilling various essential functions for the organism.
- Through this text we will show you the structure.
- How the differentiation process develops and the functions of this amazing exchange center Let’s start exploring!.
To begin with, it is necessary to understand the origin of the rhombencephalus. To do this, it is important to clarify what differentiation is. According to Bears Connors and Paradiso, authors of the book “Neuroscience: The Exploration of the Brain”, it is a process by which structures become more complex and functionally specialized.
The first step in brain differentiation is the development of three thickenings called primary neural tube vesicles, which originate at the rostral end.
The most rostral part of the primary vesicles is the anterior or anterior brain. The gallbladder behind the anterior brain is called a mid-brain or mid-brain, and the most caudal part of the gallbladders is the posterior brain or rhombencephalus, which in turn connects to the caudal part of the neural tube.
The rhombencephalus is then formed during embryonic development, this occurs through cross-sectional segmentations, called rhombomers, compartments that allow the creation of groups of cells that will develop differently, in addition to dealing with different functions. The rhombencephalus differs in three essential structures:
In the gallbladder stage, the rostral encephalus in the cross section is tube-shaped; Subsequently, the lip or rhombic tissue of the dorsolateral wall of the tube develops in a rostral and medial direction until it fuses with the opposite side. this fusion forms the cerebellum and the ventral wall of the tube expands to form the bridge or lump.
On the other hand, during the differentiation of half the flow of the rhombnecephalus in a spinal bulb, certain changes occur, although less pronounced. On the one hand, the walls dilate and leave only the ceiling covered with non-neural ependmary cells. On the other hand, white substance systems are present along the ventral surface on either side of the spinal bulb.
Finally, as for the space occupied by cerebrospinal fluid, it will become the fourth ventricle, which will have a continuation such as the brain aqueduct of the mesencephalus.
The posterior brain has several functions
From now on, entries from the spinal cord provide information about the spatial position of the body, and the bridge entrances are responsible for transporting information from the cerebral cortex and specifying the purpose of the movement.
When there is no proper brain development, the rhombencephalus may be affected, as well as its functions, which are vital to our survival. Let’s look at other diseases:
Therefore, the rhombencephalus is a fundamental part of our body, through its motor, sensory and visceral functions contributes to its regulation, if it fails or does not work properly the consequences can seriously affect our survival.
