adrenal glands!
The adrenal gland is divided into an inner adrenal medulla and an outer adrenal cortex. As the name 'adrenal' suggests, the adrenal glands secrete the peptide hormone adrenaline (epinephrine) which is involved in the fight-or-flight response. This is secreted by the adrenal medulla. The adrenal 'cortex' is involved in secreting corticosteroids, important fat-soluble hormones in the body. Since it is a gland that secretes hormones, it is known as an endocrine gland, part of the endocrine system.
The fight-or-flight response is influenced and enhanced by the adrenal system. When an animal senses danger, on-rushing epinephrine springs them into action.
The sympathetic nervous system. The hypothalamus, in close association with the limbic system of the brain. The "fight or flight" response is the term used for the activation of the sympathetic nervous system. The two main chemicals invoved here are the neurotransmitter "norepinephrine" (noradrenaline) and the hormone "epinephrine" (adrenaline). Noradrenaline is produced in the neurones and is secreted at the synapse to exert its "sympathetic" activity on various organs throughout the body. The nervous system is also responsible for eliciting epinephrine production from the adrenal medulla (a part of the suprarenal glands situtated on the top of each kidney).

Adrenal Medulla
The adrenal glands release adrenaline, the hormone most often associated with the fight or flight response and danger.
Some people are allergic because of the rubber and the material can be irritating. Allergies are an immune response and a protective mechanism to fight off bacteria. Allergies are caused by the immune system being hypersensitive. If you are allergic to silicone rubber, you may have other allergies as well.
The sympathetic nervous system is responsible for the fight of flight response. The the adrenal glands release epinephrine in the fight or flight response, and norepinephrine after the threat ceases.
It is called the Immune System. A bit of extra info: The Immune System is the cause of Allergies. It goes too far when trying to protect the body from something. ENDOCRINE SYSTEM
The adrenal medulla is responsible for the fight-or-flight response. It releases a hormonal cascade that results in the secretion of epinephrine and nonrepinephrine.
Adrenaline (epinephrine) is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for "fight or flight".
