Endocine System Flashcards
Negative feedback mechanism
Reduces/removes a stimulus
Positive feedback mechanism
Enhances a stimulus
Protein hormones
Chains of amino acids
Steroid hormones
Lipids (estrogen, testosterone)
Biogenic amines
Changes the structure of an amino acid (thyroid, dopamine)
Control center for endocrine system
Hypothalamus
Hormones hypothalamus releases
Releasing hormones (RH)
Inhibiting hormones (IH)
Pituitary gland hormones
Oxytocin (OT)
Antidiuretic hormone (ADH)
3 parts of anterior pituitary gland
Pars distalis
Pars intermedia
Pars tuberalis
Hormones anterior pituitary gland releases
Thyrotrophic (TSH)
Mammotrophic (PRL)
Gonadotrophic (FSH) (LH)
Corticotrophic (ACTH)
Somatotrophic (GH)
Pars intermedia (MSH)
Parts of posterior pituitary gland
Supraoptic nuclei
Paraventricular nuclei
Hormone supraoptic nuclei relseases
ADH (antidiuretic hormone)
Hormone paraventricular nuclei releases
OT (oxytocin)
Hormone parafollicular cells secrete
Calcitonin (reduces blood calcium through urination)
Function of parathyroid hormone
Raises blood calcium levels
