The brain stem is about the size of a thumb in diameter and approximately 3 inches (approximately 7.5 cm) long. It structures are the midbrain, pons, and the medulla obongata. The midbrain is mostly composed of tracts of nerve fibers. The midbrain has two bulging fiber tract-cerebral peduncles. It also has four rounded protrusions. The midbrain reflex centers for vision and hearing. The pons are the bulging center part of the brain stem. It is mostly composed of fiber tracts. It includes nuclei involved in the control of breathing. The medulla oblongata is the lowest part of the brain stem, it merges into the spinal cord, includes important fiber tracts, and contains important control centers. Heart rate control, blood pressure regulation, breathing, swallowing and vomiting. Recticular formation, diffus mass of gray matter along the brain stem. Involved in motor control of visceral organs. Reticular activating system plays a role in awake/ sleep cycles and consciousness
What else can I help you with?
The brainstem is to arousal as the limbic system is to?
The brainstem is to arousal as the limbic system is to emotion.
What is it called when the brainstem is pushed through the base of the skull?
This is called brainstem herniation and may result in coma or death due to pressure on the vital respiratory centers in the brainstem.
Is the brainstem the upper most layer of the brain?
No, the brainstem is down low, like the stem of a flower.
Is sheep brainstem bigger or smaller then a human brainstem?
it is smaller sheep are very dump animals
What is the main purpose of the brainstem?
Brainstem regulates the breathing, heart rate, sleeping and etaing. All information relayed from the body to the cerebrum and cerebellum and vice versa.And the brainstem transveres it.
What serves as a bridge between the brainstem and the cerebellum?
The Pons - The Pons includes a bridge of fibers that connects the brainstem with the cerebellum.
How is the cerebellum physicaly connected to the brainstem?
The cerebellum connects to the brainstem via the pons, which are just above the medulla oblongota.
What part of the body controls functions like breathing and heartbeat?
BRAINSTEM The medulla (located in the lower half of the brainstem).
What part of the brain is reticular formation?
The reticular formation is a network of neurons located in the brainstem. It is involved in regulating arousal, attention, and sleep-wake cycles.
What is significant about the brainstem?
The brainstem controls several body functions. Heart rate, Blood pressure, alertness and arousal are all controlled by the brainstem. In infants, there are studies that prove that the brain stem is partly in control of auditory functions.
How does blood get to the brainstem?
through your veins
What is the procedure of a brainstem surgery?
you have to be a proffesional
