Chapter 8: Neuroendocrinology Flashcards
(23 cards)
A chemical signal that is released outside the body by one species and affects the behavior of other species.
allomone
Also called monoamine hormone. A hormone composed of a single amino acid that has been modified into a related molecule, such as melatonin or epinephrine.
amine hormone
Any of a class of hormones that includes testosterone and other male hormones.
androgen
The front division of the pituitary gland; it secretes tropic hormones.
anterior pituitary
Also called antidiuretic hormone. A peptide hormone from the posterior pituitary that promotes water conservation and increases blood pressure.
arginine vasopressin (AVP) or vasopressin
A gland that secretes products into the bloodstream to act on distant targets.
endocrine gland
Referring to glands that release chemicals to the interior of the body. These glands secrete the principal hormones used by the body.
endocrine
Any of a class of steroid hormones produced by female gonads.
estrogen
A gonadotropin, named for its actions on ovarian follicles.
follicle-stimulating hormone (FSH)
An anterior pituitary hormone that selectively stimulates the cells of the gonads to produce sex steroids and gametes.
gonadotropin
A hypothalamic hormone that controls the release of luteinizing hormone and follicle-stimulating hormone from the pituitary.
gonadotropin-releasing hormone (GnRH)
A chemical secreted by an endocrine gland that is conveyed by the bloodstream and regulates target organs or tissues.
hormone
A hormone, released from the posterior pituitary, that triggers milk letdown in the nursing female.
oxytocin
A chemical signal that is released outside the body of an animal and affects other members of the same species.
pheromone
A small, complex endocrine gland located in a socket at the base of the skull.
pituitary gland
A hormone that consists of a string of amino acids.
protein hormone or peptide hormone
A slow-acting substance in a target cell that amplifies the effects of synaptic or hormonal activity and regulates activity within the target cell.
second messenger
Oxytoxin, Insulin, and Vasopressin are _______ hormones.
Protein hormones
Epinephrine, norepinephrine, and melatonin are _______ hormones.
Amine hormones
Glucocorticoids, androgens, and estrogens are ________ hormones.
Steroid hormnes
ACTH, FSH, LH, TSH, growth hormone and glucagon are _______ hormnes.
Protein hormones.
Research method when a brain is sliced in thin sections and placed on photographic film. Radioactive emissions from the tissue expose the film.
Autoradiography
Research method that enables us to map the distribution of hormone receptors in the brain. Specific antibodies seek out and bind to receptors on slices of brain tissue.
Immunocytochemistry
