The medulla consists of nerve fibers and cell bodies that control vital bodily functions such as heart rate, breathing, and blood pressure. It also contains the reticular formation, which helps regulate consciousness and sleep-wake cycles.
The majority of nerve fibers cross from the right to the left at the level of the medulla oblongata in the brainstem. This crossing, known as decussation, occurs in structures like the pyramids in the medulla.
preganglionic sympathetic fibers releasing acetylcholine that bind to receptors on the adrenal medulla
No, postganglionic fibers release norepinephrine, not epinephrine. Epinephrine is released by the adrenal medulla.

There is considerable variation in the extent to which decussation takes place in the medulla oblongata; about two-thirds or three-fourths of the fibers usually decussate in the medulla oblongata and the remainder in the medulla spinalis.
Fibers made of long, narrow, sclerenchyma cells with thick secondary walls surround the xylem tissue. They provide strength and support to the xylem tissue.
Cytoskeleton consists of connecting fibers that enable the cell to function as a unit.
