Anterior Pituitary

LH and FSH

Hypothalamus --> GNRH --> AP --> FSH and LH --> gonads --> testes and ovaries

FSH --> maturation of ovarian follicle with LH (oestrogen production in females and sperm production in males

LH --> triggers ovlulation, formation of corpues luteum, oestrogen and progesterone production

Negative feedback

Hypothalamus --> Thyrotropin releasing hormne --> AP --> TSH --> t3 and t4 at thyroid

t3 --> metabolism and increases energy

t4 --> converted into t4 in tissues

negative feedback

Prolactin --> milk secretion (stimulates secretion)

Ejection of the milk you will require oxytocin (post pit)

Regulates prolactin via dopamine (inhibits prolactin secretion) and PRH (stimulates prolactin secretion)

Hypothalamus --> GHRH--> Growth hormone (targets bone, skeletal muscle)

Hypothalamus --> CRH --> AP --> ACTH --> adrenal cortex --> cortisol and other glucocorticoids

Excess release of CRH --> stimulate melanocyte stimulating hormone --> inhibited by dopamine
