Bio 202 Lab Quiz 1 (Rio Salado)
Endocrine system - answer second major controlling system of the body
acts with nervous system to help coordinate and integrate the activity of the body's cells
Hormones - answerchemical messengers the endocrine system employs that are
released into the blood to be transported throughout the body
Target organs - answerorgans that respond to a particular hormone
Which hormone-producing glands are endocrine? - answer Anterior pituitary
Thyroid
Adrenals
Parathyroid
Which hormone-producing glands are endocrine and exocrine? - answer pancreas
gonads
How do endocrine glands release their hormones? - answerrelease their hormones
directly into the blood or lymph (ductless)
How do exocrine glands release their hormones? - answerrelease their products at the
body's surface or outside an epithelial membrane via ducts
Where are non-endocrine hormone-producing cells located? - answerwithin the
intestine, stomach, kidney, and placenta
What is the pituitary gland also known as? - answerHypophysis
Where is the pituitary gland located? - answerlocated in the concavity of the sella
turcica of the sphenoid bone
What are two lobes of the pituitary gland? - answeranterior pituitary (adenohypophysis)
and posterior pituitary (neurohypophysis)
The pituitary gland is attached to the hypothalamus by a stalk...this stalk is called? -
answerinfundibulum
What is a tropic hormone? - answerstimulates its target organ (endocrine gland) to
secrete its hormones
What are the four tropic hormones of the anterior pituitary? - answerFollicle-stimulating
hormone (FSH)
, Luteinizing hormone (LH)
Adrenocorticotropic hormone (ACTH)
Thyroid-stimulating hormone (TSH)/thyrotropin
What group is FSH and LH a part of? - answerGonadotropins
What do FSH and LH do? - answerregulate gamete production and hormonal activity of
the gonads (ovaries and testes)
What does ACTH do? - answerregulates the endocrine activity of the cortex portion of
the adrenal gland
What does TSH/thyrotropin do? - answerinfluences the growth and activity of the thyroid
gland
What hormones are not directly involved in the regulation of other endocrine glands and
are produced by the anterior pituitary? - answerGrowth hormone (GH)
Prolactin (PRL)
What does GH do? - answera general metabolic hormone that plays an important role in
determining body size, major effects are exerted on the growth of muscle and long
bones of the body
What does hyposecretion of GH cause? - answerresults in pituitary dwarfism in children
What does hypersecretion of GH cause? - answercauses gigantism in children and
acromegaly (overgrowth of bones in hands, feet, and face) in adults
What does PRL do? - answerstimulates breast development and promotes and
maintains lactation by the mammary glands after childbirth, may stimulate testosterone
production in males
What are other secretory products of the anterior pituitary? - answerMelanocyte-
stimulating hormone (MSH), endorphins, lipotropin
What gland is also known as the master endocrine gland because it controls the activity
of so many other endocrine glands? - answeranterior pituitary
What controls the release of hormones from the anterior pituitary? -
answerneurosecretions (releasing or inhibiting hormones) produced by the neurons of
the ventral hypothalamus
What are hypothalamic hormones freed into to serve the circulatory needs of the
anterior pituitary? - answerhypophyseal portal system
