Stimulate
Exocrine glands
Release secretions into duct that carries them to outside of body (sweat glands)
Endocrine glands
Release hormone directly into bloody area (thyroid)
Corticosteroids
Secreted by the adrenal cortex, steroid
Epinephrine & norepinephrine
Released by adrenal medulla
Exocrine portion of pancreas
Releases digestive enzymes through duct into duodenum
Endocrine portion of pancreas
Islets of langerhans, produces insulin and glucagon
Insulin
Produced by beta cells, stimulates cells of body to take in glucose from
Bloodstream, lowers blood sugar
Glucagon
Produced by alpha cells, stimulates over to release stores glucose into bloodstream, raises blood sugar levels
Parathyroid hormone (PTH)
Regulates level of calcium in bloodstream
Pineal gland
Secretes melatonin
Anterior pituitary
Referred to as “master gland,” secretes TSH thyroid stimulating hormone and ACTH adrenocorticotropin hormone
Posterior pituitary
Antidiuretic hormones and oxytocin
Thymus gland
Mediastinum, secretes thymosin which is essential for growth and development of thymic lymphocytes
Thyroid gland
Calcitonin
Exophthalmos
Protruding eyeballs
Hirsutism
Excessive amount of hair
Addison’s disease
Generalized weakness and weightloss, hypo secretion of adrenal cortex
Adrenal virilism
Hypersecretion of testosterone by adrenal cortex in females, develop male secondary characteristics
Addison’s disease
Hypo secretion of adrenal cortex; weakness and weight loss
Cushing’s
Hyperseretion of adrenal cortex; weakness, edema, osteoporosis
Diabetes mellitus
Hyperglycemia and glucosuria
Type I insulin dependent diabetes
Destruction of islet cells, make too little insulin, must get injections
Non-insulin dependent diabetes mellitus type II
Lost ability to regulate cells, do not take insulin, treated by diet & exercise
Diabetes insipid us
Hypo secretion of anti diuretic hormone, polyuria and polydipsia
Goiter
Enlarged thyroid gland
Radioimmunoassay (RIA)
Measures levels of hormones in blood
Protein bound iodine test (PBI)
Measures T4 blood level
GTT
Glucose tolerance test
