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
The entire brainstem is required for life.
The brainstem is to arousal as the limbic system is to emotion.
Inside the brainstem
This is called brainstem herniation and may result in coma or death due to pressure on the vital respiratory centers in the brainstem.
it is smaller sheep are very dump animals
No, the brainstem is down low, like the stem of a flower.
The brainstem is made up of midbrain. Not sure about hindbrain.
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.
The Brainstem is the lower extension of the brain where it connects to the spinal cord.
The cerebellum connects to the brainstem via the pons, which are just above the medulla oblongota.
BRAINSTEM The medulla (located in the lower half of the brainstem).
The Pons - The Pons includes a bridge of fibers that connects the brainstem with the cerebellum.
