The two major systems involved in the stress response are the Nervous System [the Sympathetic subdivision of the Autonomic Nervous System (ANS)] and the Endocrine System (glands which secrete hormones intonthe bloodstream).
The Endocrine System's response during acute and/or chronic stress (adaptation) involves first the Hypothalamic release of Corticotropin-Releasing Hormone (CRH), which stimulates the Anterior Pituitary (via the blood) to release AdrenoCorticoTropic Hormone (ACTH), which then activates the Adrenal Cortex to release glucocorticoid hormones (i.e. Cortisol), amongst others into the bloodstream. Cortisol then has many effects on tissues and organs throughout the body to allow better generalized coping with the initial stress stimulus.

Answer:
The correct answer is - Cholinergic antagonists.
Explanation:
The cholinergic antagonist is a class of medication that is general terms of agents that bind with choline receptors such as nicotinic and muscarinic that inhibit the effect of acetylcholine and another agonist.
It is a class of drugs that mimics, inhibit, or enhance the action of the neurotransmitter ACh which is the very first transmitter of nerve impulse within PNS that includes the region of ANS that regulates contraction of smooth muscle, such as upper respiratory tract.
Thus, the correct answer is - Cholinergic antagonist.
