    1. Secretion of the hormone melatonin
    2. Regulation of endocrine functions
    3. Conversion of nervous system signals to endocrine signals
    4. Causes sleepiness
    5. Influences sexual development
    6. Influences immune system function
    7. Antioxidant activity

At both low and high magnification, one can readily differentiate these zones based on the pattern produced by cords of cells. However, the boundaries between zones are indistinct.]]> 2019-03-25 17:06:49 UTC https://padlet.com/khusaireishak/iug78m5b3fr4/wish/344926766 Location adrenal gland khusaireishak https://padlet.com/khusaireishak/iug78m5b3fr4/wish/344927279 upper poles of each kidney on right and left sides]]> 2019-03-25 17:07:52 UTC https://padlet.com/khusaireishak/iug78m5b3fr4/wish/344927279 Hormones pineal gland khusaireishak https://padlet.com/khusaireishak/iug78m5b3fr4/wish/344927902 The pineal gland is a tiny endocrine gland found in the brain. It produces and secretes the hormone melatonin, which is a hormone that helps regulate biological rhythms such as sleep and wake cycles. The secretion of melatonin is inhibited by light and triggered by darkness.]]> 2019-03-25 17:09:04 UTC https://padlet.com/khusaireishak/iug78m5b3fr4/wish/344927902 Hormones Adrenal gland khusaireishak https://padlet.com/khusaireishak/iug78m5b3fr4/wish/344928542 The adrenal cortex produces three hormones:

    • -Mineralocorticoids: the most important of which is aldosterone. This hormone helps to maintain the body’s salt and water levels which, in turn, regulates blood pressure. 
    • -Glucocorticoids: predominantly cortisol. This hormone is involved in the response to illness and also helps to regulate body metabolism. 
    • -Adrenal androgens: male sex hormones mainly dehydroepiandrosterone (DHEA) and testosterone. All have weak effects, but play a role in early development of the male sex organs in childhood, and female body hair during puberty.
