source: diverse tissue in body
target: local cells within the source tissue
Principal action: Diverse local (paracrine/autocrine) effects such as regulation of inflammation, muscle contraction in blood vessels
Prostagladins (PG's)
Source: Platelets
Target: Other platelets; muscles in blood vessel walls
Principal action; Increases stickiness of platelets; promot blood clotting; cause constriction of blood vessels
Thromboxanes (TXs)
source: several types of WBC (leukocytes)
target: local cells of various types
Principle action: produce local inflammation triggered b allergens, including constriction of airways (as in asthma) and other inflammatory responses
Leukotrienes
Source: hypothalamus
target: adenohypophysis
Principal Action: stimulates secretion (release) of growth hormone
Growth hormone - releasing hormone (GHRH)
source: hypothalamus
target: adenohypophysis
Principal action: inhibits secretion of growth hormone
Growth hormone - hihibiting hormone (GHIH) or Somatostatin
source: hypothalamus
Target: adenohypophysis (corticotrophs)
Principal action: Stimulates release of adrenocorticotrophic hormone (ACTH)
Corticotropin - releasing hormone (CRH)
Source: Hypothalamus
Target: Adenohypophysis (thyrotrophs)
Principal Action: Stimulates release of thyroid stimulating hormone (TSH)
Thyrotropin releasing hormone (TRH)
Source: Hypothalamus
Target: Adenohypophysis (gonadotrophs)
Principal Action: Simulates release of gonadotropins (FSH and LH)
Gonadotropin - releasing hormone GnRH)
Source: Hypothalamus
Target: Adenohypophysis (Corticotrophs)
Principal Action: stimulates secretion of prolactin
Prolactin- releasing hormone (PRH)
