Identify the primary vesicles that form during brain development.
To determine:
The primary vesicles formed during brain development.
Introduction:
In order to understand the name of the structures of the adult brain and their connectivity, it is necessary to know about brain development. In the human embryo, the brain forms from the superior part of the neural tube that undergoes unequal growth rates in different regions.
Explanation of Solution
The three primary brain vesicles are formed by the fourth week of brain development. These vesicles will finally give rise to all the different regions of the adult brain. The names of these vesicles explain their relative positions in the developing head:
• The prosencephalon:
The prosencephalon is also called the hindbrain of the head.
• The mesencephalon:
The mesencephalon is also called the midbrain of the head.
• The rhombencephalon:
The rhombencephalon is also called the hindbrain of the head.
