ANAT & PHYS: ENDOCR
ANAT & PHYS: ENDOCRINE SYSTEM
| Question | Answer |
|---|---|
| releases gonadotropin-releasinghormone (GnRH) | The hypothalamus |
| GnRH stimulates the anterior pituitary to secrete | FSH and LH |
| stimulates interstitial cells to release testosterone | LH |
| Pituitary hypersecretion in adulthood will result in this disease | acromegaly |
| Which gland is associated with serotonin and melatonin production? | pineal |
| Hyperparathyroidism causes | bone resorption and renal calculi |
| Which concept explains the fact that target cells do not have a great number of receptors and normal circulating blood concentrations of hormones are very low? | enzyme amplification |
| Chemical messengers that don't travel in blood but simply diffuse into and affect nearby cells are called ________ secretions. | paracrine |
| helps to avoid dehydration or water overload. Prevents urine formation | antidiuretic hormone |
| A lack of antidiuretic hormone will lead to | diabetes insipidus |
| This hormone raises blood calcium levels | parathyroid hormone |
| Hormones circulate to all tissues but only activate cells referred to as | target cells |
| Triggered by hypothalamic corticotropin-releasing hormone (CRH) in a daily rhythm.Internal and external factors such as fever, hypoglycemia, and stressors can trigger the release of | Adrenocorticotropic Hormone (Corticotropin) |
| stimulates gamete (egg or sperm) production | FSH |
| LH works alone to trigger | ovulation |
| LH works with FSH to cause maturation of the | ovarian follicle |
| In females, stimulates milk production by the breasts | Prolactin (PRL) |
| stimulates smooth muscle contraction in breasts and uterus | Oxytocin |
| ADH and oxytocin are synthesized in the | hypothalamus |
| Thyroid Hormone IS the body’s major | metabolic hormone |
| The largest endocrine gland, located in the anterior neck, consists of two lateral lobes connected by a median tissue mass called the isthmus | Thyroid Gland |
| plays a role in: Maintaining blood pressure, Regulating Tissue growth AND Developing skeletal and nervous systems.Maturation and reproductive capabilities | Thyroid Hormone |
| A peptide hormone produced by the parafollicular, or C, cells.Lowers blood calcium levels in children | Calcitonin |
| regulates calcium balance in the blood | PTH (parathormone) |
| Maintains Na+ balance by reducing excretion of sodium from the body | Aldosterone |
| Works under the sympathetic nervous system; more potent stimulator of the heart and metabolic activities; used to dilate bronchioles during asthma attack | norepinephrine |
| Stimulates the adrenal cortex to release hormones | ACTH |
| The interstitial cells of the testes are stimulated by LH to secrete . | testosterone |
| Which gland secretes calcitonin and a hormone that stimulates ATP production? | thyroid gland |
| Estradiol is produced by | granulosa cells of the ovary |
| Chemical messengers that don't travel in blood but simply diffuse into and affect nearby cells are called ________ secretions. | paracrine, or local hormones |
| Which hormone will cause a fall in blood glucose concentrations? | insulin |
