How does the brain stem develop?

When an embryo reaches the seventh week, the first fully developed nerve cells, called neurons, can be found topping the spinal cord and forming the brain stem, according to Ronan O’Rahilly, director of the Carnegie Laboratories of Embryology at UC Davis.Click to see full answer. Similarly, why does the brain stem develop first?Brain stem: responsible for basic survival functions such as breathing and heartbeat. The brain stem begins developing first, followed by the cerebellum, the limbic system, and finally the cerebral cortex. The fact that the limbic system develops before the cortex is important.Subsequently, question is, how does the brain stem work? The brain stem sits beneath the cerebrum and in front of the cerebellum. It connects the rest of the brain to the spinal cord, which runs down your neck and back. The brain stem is in charge of all the functions your body needs to stay alive, like breathing air, digesting food, and circulating blood. Secondly, at what age is the brain stem fully developed? age 25 or so What are the 3 parts of the brainstem and their functions?Brainstem. The brainstem (brain stem) is the distal part of the brain that is made up of the midbrain, pons, and medulla oblongata. Each of the three components has its own unique structure and function. Together, they help to regulate breathing, heart rate, blood pressure, and several other important functions.
