You are in the forest and see a large, snarling, drooling grizzly bear running directly toward you. The adrenaline rush you feel as you run toward the cabin is controlled by the sympathetic nervous system.
The sympathetic nervous system is a part of the autonomic nervous system which functions through various interconnected neurons. The sympathetic nervous system’s main role is to stimulate the neuronal and hormonal stress response (also known as body's fight-or-flight response). The sympathetic fibers in the adrenal medulla (inner part of the adrenal gland) produce acetylcholine (a neurotransmitter), which allow the high secretion of adrenaline and low amounts of noradrenaline from it.

The plants can be classified based on their vascular and reproductive structures. The plant given in the image belongs to the Bryophyta.
<h3>What is Bryophyta?</h3>
The non-vascular plants that are a part of the plant classification are found in moist places and are small in size belongs to the Bryophyta.
The plant of this classification have a leafy multicelled plant body, that lacks true leaves, roots, and stems. They are green plants and also contains chloroplast for food synthesis.
