glands ave a tremendous anti-inflammatory effect on the immune system which is why horses with PPID show signs of poor immunity like chronic dermatitis‚ foot abscesses‚ and poor wound healing. The adrenal glands also produce the catecholamines‚ epinephrine and norepinephrine. These hormones are responsible for the “fight or flight” response when a threat is sensed. The disease of the adrenal glands is very rare. Next is the thyroid glands. The thyroid gland straddles the trachea just behind the larynx
