QuestionAnswer
this class of hormones does not readily need transport proteins when released in the blood
the portion of the adrenal gland that produces steroid hormones
regulates body rhythms and day/night cycles and inhibits secretion of gonadotropin-releasing hormone (GnRH) from the hypothalamus, which regulates the release of FSH and LH.
released upon the endocytosis and lysosomal degradation of iodothyroglobulin
growth hormone is released by acidophils or basophils of the anterior pituitary?
develops from the thickened lateral walls of the pouch of the anterior pituitary and forms a collar or sheath around the infundibulum
regulates maturation of ovarian follicle, ovulation, and corpus luteum formation
hormonal control classified as hormones secreted from one cell to act on adjacent cells.
True or False: The release of catecholamines and peptide hormones occurs by merocrine secretion, while thyroxine and steroid hormones diffuse across the membrane.
embryologic origin of the anterior lobe of the pituitary?
stimulates follicular development and spermatogenesis
gel-like mass within the thyroid follicle
calcified concretions in the pineal gland
this molecule inhibits the release of prolactin
neurotransmitters synthesized from tryptophan
thryrotropic hormone (TSH) is released by acidophils or basophils of the anterior pituitary?
hormonal control classified as hormones secreted and acts on same cell
embryologic origin of the posterior lobe of the pituitary?
somatostatin _____ the release of growth hormone.
comprises the bulk of the anterior lobe of the pituitary gland. arises from the thickened anterior wall of the pouch
release of aldosterone from the adrenal gland is stimulated by what?
the inner zone of the adrenal cortex that is involved in producing the sex hormones or androgens
insulin, glucagon, growth hormone, and FSH are examples of what class of hormone?
adrenocorticotropic hormone (ACTH) is released by acidophils or basophils of the anterior pituitary?
principal component of the colloid
QuestionAnswer
this hormone decreases blood calcium by stimulating absorption of calcium by the bones
which pituitary lobe is known as the neurohypohysis?
endocrine gland that regulates daily body rhythm
what hormone stimulates the release of growth hormone?
prolactin is released by acidophils or basophils of the anterior pituitary?
this class of hormones is translated by ribosomes at the rough endoplasmic reticulum, packaged in the Golgi apparatus, and transported to the cell surface via secretory vesicles
an indolamine whose synthesis and release via diffusion through the membrane is enhanced during the dark cycle.
what embryonic structure descends in the neck and divides into left and right thyroid lobes.
this class of hormones is synthesized from cholesterol by enzymes present in mitochondria and endoplasmic reticulum
this hormone increases blood calcium by promoting release from bones
oxytocin is secreted by the ______ nuclei?
synthesized from tyrosine and packaged into secretory vesicles
these cells are responsible for the production of T3 and T4
luteinizing hormone (LH) is released by acidophils or basophils of the anterior pituitary?
hormone promotes mammary growth and initiates milk formation
cells specific to the posterior pituitary
maintains structure and stimulates secretion of glucocorticoids and gonadocorticoids.
decreases urine volume by increasing reabsorption of water by collecting ducts, decreases perspiration in response to dehydration, and increases blood pressure by stimulating contr
_____ _____ _____is a disorder related to a abnormal regulation of day/night cycles.
portion of the posterior pituitary that contains neurosecretory axons and their endings
membrane bound neurosecretory granules unite to form _____ ____ that contain oxytocin and vasopressin.
which pituitary lobe is known as the adrenohypohysis?
gonadal and adrenocortical hormones are examples of what class of hormone?
ADH is secreted by the ______ nuclei.
follicle-stimulating hormone (FSH) is is released by acidophils or basophils of the anterior pituitary?
QuestionAnswer
hormone release by the anterior pituitary stimulates kidney and liver to secrete IGF-1, which stimulates bone growth
_____ is an iodinated tyrosine derivative embedded within thyroglobulin, which is released during the endocytosis and lysosomal degradation. _______ then diffuses out of the cell.

how many hormones are secreted by the anterior pituitary?
a roughly spherical cystlike compartment with a wall formed by simple cuboidal epithelium
narrow outer zone of the adrenal cortex that secretes mineralcortacoids
