|
They form from modified sympathetic ganglionic neurons
|
|
|
Which of the following results from the overproduction of thyroid hormone?
|
Grave's disease
|
|
|
The thyroid gland is located just anterior to the
|
trachea
|
|
|
Hypothalamic centers regulate nervous and endocrine system activities by
|
-acting as an endocrine organ, releasing ADH and oxytocin
-direct control over endocrine cells -secreting regulatory hormones to control pituitary gland activities -all of the above! |
|
|
The lobes of the thyroid gland are connected by the
|
isthmus
|
|
|
The 2 hormones released by the neurohypophysis are
|
ADH and oxytocin
|
|
|

|
|
|
Calcitriol is
|
-released in response to PTH
-a form of vitamin D -used to increase blood calcium levels -a steroid ALL |
|
|
Which of the following describes the function of c cells/parafollicular cells
|
they produce the hormone calcitonin
|
|
|
Releasing hormones (RH) directly cause
|
increased secretion from the anterior pituitary
|
|
|
The hormone that acts to oppose the effects of calcitonin is
|
-secreted by the parathyroid glands
--parathyroid hormone |
|
|
Decreased levels of parathyroid hormone could result in
|
muscle spasms
|
|
|
The hypophyseal portal system allows
|
regulating hormones to go directly from the hypothalamus to the anterior pituitary
|
|
|
The anterior pituitary can be divided into three regions:
|
pars distalis, pars tuberalis, and pars intermedia
|
|
|
The most important hormone produced by the pineal gland is
|
melatonin
|
|
