Endocrine Glands

For each major endocrine gland lsited below, identify the hormone(s) they produced/secreted, the target tissue(s) and describe the effect of the hormones on their target tissue(s):

Hypothalamus - control centre for the endocrine system.

(neuroendocrine organ)

• Releasing hormones:

  • Growth hormone releasing hormone (GHRH): stimulates the release of growth hormone (GH)

  • Gonadotropin releasing hormone (GnRH): stimulates the release of luteinizing hormone (LH) and follicle stimulating hormone (FSH)

  • Corticotropin releasing hormone (CRH): stimulates the release of adrenocorticotrophic hormone (ACTH)

  • Thyrotropin releasing hormone (TRH): stimulates the release of thyroid stimulating hormone (TSH)

• Inhibiting hormones:

  • Prolactin inhibiting hormone (PIH)/dopamine: inhibits the release of prolactin

  • Growth hormone inhibiting hormone (GHIH)/somatostatin: inhibits the release of growth hormone

• set of regulatory hormones that control the release of hormones produced by the anterior pituitary gland 

Anterior pituitary gland

Posterior pituitary gland

Thyroid gland

Parathyroid glands

Adrenal glands

Pancreas

Testes

Ovaries

Endocrine Gland (lose ducts)

• SLOW delivery of commands via hormones

• Secrete hormones into bloodstream (blood vessels weave though gland tissue)

• (one of the homeostatic communication pathways) and this complex group of glands and hormones are generally considered their own 'body system'

Exocrine Glands

• Release secretions through ducts onto epithelial surfaces, serving both internal and external functions.

• Protein secretion: Sweat and oil glans (not hormones)
