The Functions of Each Glands
Pituitary Gland
They are the master gland. It therefore, influences the release of hormones from other glands.
It is controlled by the hypothalamus.
It produces hormones which travel to the bloodstream to specific targets. These hormones either cause == Cause changes in physiological processes in the body or ==
Stimulate other glands to produce hormones
Releases =
Oxytocin
Action of the Hormone =
Stimulates contractions in the uterus during childbirth
Aids conception and creates feelings of relaxation and calm
Encourages strong bonding between couples/child and mother
The Pituitary gland has two main parts:
The posterior (back) which releases oxytocin which stimulates contractions in the uterus during child birth.
Anterior (front) which releases ACTH which is vital to the stress response.
Adrenal glands
They sit at the top of the kidneys.
They are made of two distinct parts: the adrenal cortex and the adrenal medulla.
Adrenal cortex
Cortisol
Regulates or supports important bodily functions like, anti-inflammatory functions.
Aids the body’s stress response.
Low cortisol levels lead to low blood pressure, immune functioning and an inability to deal with stress.
Aldosterone
Responsible for maintaining blood volume and pressure .
Adrenal medulla
Adrenaline
Prepares the body for fight or flight. It helps individual to prepare for stressful situations by increasing heart rate and blood flow to muscles and brain helping with the conversion of glycogen to glucose to energy.
Noradrenaline
Constricts blood vessels allowing blood pressure to increase.
Ovaries
Part of the female reproductive system
Responsible for production of eggs and the hormones: oestrogen and progesterone
Progestrogen
It is more important in the post ovulation phase, it is associated with heightened sensitivity to social cues that indicate the presence of social opportunity or threat that would be significant in the case of pregnancy.
Essentially about identifying threat / allies which would be key if pregnant
Testes
Male reproductive glands which produce testosterone.
Testosterone
Causes the development of male characteristics like, growth facial hair and deepening of the voice.
Hypothalamus instructs pituitary gland on how much testosterone to produce, pituitary gland passes message to testes.
Plays a role in: sex drive, sperm production, muscular strength, overall health and wellbeing in men.
Not exclusively a male hormone - women have in smaller amounts.
