is co-secreted with GnRH

acts to oppose the action of antidiuretic hormone

is released from the anterior pituitary

is also referred to as a cardiac hormone

is also referred to as antidiuretic hormone

inhibits cortisol secretion from the adrenal cortex

stimulates adrenaline secretion from the adrenal medulla

inhibits aldosterone secretion from the adrenal cortex

stimulates cortisol secretion from the adrenal cortex

ACTH & prolactin

Vasopressin and oxytocin

Vasopressin & prolactin

Vasopressin and ACTH

There are no differences; both act by binding to receptors on the cell surface

Peptide hormones bind to receptors on the cell surface whereas steroid hormones bind to intracellular receptors

Peptide hormones bind to receptors on the cell surface whereas steroid hormones act as second messengers

Peptide hormones bind to intracellular receptors whereas steroid hormones bind to receptors on the cell surface

act to lower circulating anterior pituitary hormone concentrations

include somatostatin and dopamine

are secreted by nerve terminals in the median eminence.

act on the secretory cells of the posterior pituitary

are released from the terminals of axons in the posterior pituitary

increasing protein synthesis in muscles

increasing insulin secretion

increasing growth hormone secretion

increasing lipolysis

increasing gluconeogenesis

the type of blood supply of the target cell

the presence of appropriate receptor molecules

the type of nerve supply of the target cell

the proximity to the source of the hormone

blocking the action of 1,25 dihydroxy vitamin D₃

antagonising the synthesis of calcitonin

targeting the bone osteoblasts so that calcium will be released

blocking the action of growth hormone

slowing the activity of tissues that require Ca⁺⁺

decreased gluconeogenesis and glycogenolysis.

increased synthesis of fats in adipose tissue

decreased breakdown of muscle proteins

increased gluconeogenesis and glycogenolysis

increased synthesis of muscle proteins
