Inhibition and Feedback
100
The pituitary gland sits in this structure
Sella turcica of sphenoid bone "turkish saddle"
100
The posterior pituitary is considered to be an extension of ______.
hypothalamus
100
This hormone stimulates lactogenesis in the breasts
Prolactin
100
Cortisol is secreted in the _____ due to stimulation from _______ hormone.
Zona Fasiculata
Adrenocorticotropin
100
Increased _____ causes inhibition of prolactin.
Dopamine
200
The acronym FLAT PEG stands for these hormones released from the anterior pituitary
Follicular Stimulating Hormone
Luteinizing Hormone
Aderenocorticotropin
Thyroid Stimulating Hormone
Prolactin
Endorphins
Growth Hormone
200
The post. pituitary is responsible for the release of these two hormones.
Antidiuretic hormone
Oxytocin
200
This anterior pituitary hormone has downstream effects that increase fat/protein breakdown and decrease inflammation in the body.
Adrenocorticotropin (ACTH)
200
Gonadotropin Releasing Hormone stimulates the release of ______ and ______.
Follicular stimulating hormone
Luteinizing hormone
200
Typical release of ACTH occurs at higher levels during this time.
In the morning
(Cortisol secretion is higher in the morning and tapers off... this is why steroids are taken in the morning to mimic natural cortisol levels).
300
Type of feedback where the output signal is used to reduce the input signal.
Closed Loop Feedback
300
This hormone uses a positive feedback loop to produce contractions during childbirth.
Oxytocin
300
______ incites ovulation in the ovaries and testosterone secretion in the testes.
Meanwhile _______ helps to produce estradiol and progesterone in the ovaries and spermatogenesis in the testes.
1. Luteinizing hormone
2. Follicular Stimulating hormone
300
These anterior pituitary hormones are non-tropic hormones (act directly on target tissue).
Growth hormone
Prolactin
300
Hypoglycemia stimulates secretion of what two anterior pituitary hormones?
Adrenocorticotropin and Growth hormones
400
These hormones are stored in the basophils of the anterior pituitary
FSH
LH
ACTH
TSH
(Remember: B-Flat)
400
_______ nuclei releases ADH from the hypothalamus and ______ nuclei releases oxytocin.
Supraoptic
Paraventricular
400
Growth hormone secretion causes Direct or ______ effects by increasing lipolysis and blood glucose concentration.
It additionally causes Indirect or ______ effects by increasing protein synthesis and linear bone growth.
Anti-Insulin
Insulin-Like
400
After its release from the thyroid; _____ will turn into its more active form _____ at its target tissue.
T4
T3
400
Thyroid releasing hormone promotes secretion of which anterior pituitary hormone? (Hint: it's not TSH)
Prolactin
500
I'm tired and can't come up with another question so let's see if I change this later... what's my favorite color?
Royal blue
500
ADH increases fluid retention by inserting this protein in the renal collecting duct.
Aquaporin 2 channels
500
This anterior pituitary hormone increases downstream synthesis of many important protein channels and pumps including Na/K ATPase, beta 1 adrenergic receptors, and transport proteins.
Thyroid Stimulating Hormone
500
These three things provide the main negative feedback loops for Growth Hormone
1. Excess Growth hormone (closed loop feedback)
2. Somatomedins (i.e. IGF-1)
3. Somatostatin
