GENERAL HISTOLOGY

Detailed explanation-1: -The adrenal medulla, the inner part of an adrenal gland, controls hormones that initiate the flight or fight response. The main hormones secreted by the adrenal medulla include epinephrine (adrenaline) and norepinephrine (noradrenaline), which have similar functions.

Detailed explanation-2: -The Adrenal Gland, part of the endocrine system, releases cortisol into the bloodstream. Adrenaline helps to enhance cardiac function by increasing heart rate, constricting blood vessels and increasing blood pressure.

Detailed explanation-3: -Adrenocorticotropic hormone (ACTH) and the sympathetic nervous system stimulate the synthesis of adrenaline precursors by enhancing the activity of tyrosine hydroxylase and dopamine -hydroxylase, two key enzymes involved in catecholamine synthesis.

Detailed explanation-4: -adrenaline is a powerful cardiac stimulant. true. the secretion of hormones operates on a negative feedback system. true. the adrenal glands are known as the Master glands.

Detailed explanation-5: -Adrenaline is produced in the medulla in the adrenal glands as well as some of the central nervous system’s neurons. Within a couple of minutes during a stressful situation, adrenaline is quickly released into the blood, sending impulses to organs to create a specific response.
