BIOL 2402 - ENDOCRINE EXAM QUESTIONS WITH CORRECT ANSWERS LATEST UPDATE 2026
What is a hormone? - Answers A hormone is a chemical messenger produced by glands in the
endocrine system that regulates various physiological processes in the body.
What is the endocrine system? - Answers The endocrine system is a network of glands that produce
and release hormones to regulate metabolism, growth, development, tissue function, and mood.
Name several organs of the endocrine system. - Answers Several organs of the endocrine system
include the pituitary gland, thyroid gland, adrenal glands, pancreas, and gonads (ovaries and testes).
Contrast endocrine with exocrine glands. - Answers Endocrine glands release hormones directly into
the bloodstream, while exocrine glands secrete substances through ducts to external surfaces or into
cavities.
What are the standard abbreviations for many hormones? - Answers Common abbreviations for
hormones include TSH (Thyroid Stimulating Hormone), LH (Luteinizing Hormone), FSH (Follicle
Stimulating Hormone), and GH (Growth Hormone).
What are the similarities between the nervous and endocrine systems? - Answers Both systems are
involved in communication and regulation of body functions, but the nervous system uses electrical
signals for rapid responses, while the endocrine system uses hormones for slower, longer-lasting
effects.
What are the differences between the nervous and endocrine systems? - Answers The nervous
system provides fast, short-term responses to stimuli, while the endocrine system provides slower,
long-term regulation of physiological processes.
Describe the anatomical relationships between the hypothalamus and pituitary gland. - Answers The
hypothalamus is located above the pituitary gland and is connected to it by the infundibulum,
allowing it to control the pituitary's hormone release.
Distinguish between the anterior and posterior lobes of the pituitary. - Answers The anterior lobe
produces and secretes its own hormones, while the posterior lobe stores and releases hormones
produced by the hypothalamus.
List the hormones produced by the hypothalamus. - Answers The hypothalamus produces hormones
such as TRH (Thyrotropin-Releasing Hormone), CRH (Corticotropin-Releasing Hormone), GnRH
(Gonadotropin-Releasing Hormone), and GHRH (Growth Hormone-Releasing Hormone).
What hormones are produced by the anterior pituitary? - Answers The anterior pituitary produces
hormones including ACTH (Adrenocorticotropic Hormone), TSH (Thyroid Stimulating Hormone), LH
(Luteinizing Hormone), FSH (Follicle Stimulating Hormone), and GH (Growth Hormone).
What hormones are produced by the posterior pituitary? - Answers The posterior pituitary releases
oxytocin and vasopressin (ADH - Antidiuretic Hormone), which are produced in the hypothalamus.
How is the pituitary controlled by the hypothalamus? - Answers The hypothalamus releases hormones
that stimulate or inhibit the secretion of hormones from the pituitary gland, regulating its activity.
What are the effects of growth hormone? - Answers Growth hormone stimulates growth, cell
reproduction, and regeneration in the body, influencing metabolism and muscle and bone
development.
Describe the structure and location of the remaining endocrine glands. - Answers Remaining
endocrine glands include the thyroid (located in the neck), adrenal glands (on top of the kidneys),
pancreas (behind the stomach), and gonads (in the pelvic region).
What hormones do the adrenal glands produce? - Answers The adrenal glands produce hormones
such as cortisol, aldosterone, and adrenaline (epinephrine), which are involved in stress response and
metabolism.
What hormones do the thyroid gland produce? - Answers The thyroid gland produces hormones
including thyroxine (T4) and triiodothyronine (T3), which regulate metabolism and energy levels.
What are eicosanoids? - Answers Eicosanoids are signaling molecules derived from fatty acids that
play roles in inflammation, immunity, and other physiological processes.
What are some classes of eicosanoids? - Answers Classes of eicosanoids include prostaglandins,
thromboxanes, and leukotrienes, each with specific functions in the body.
What are the physiological roles of prostaglandins? - Answers Prostaglandins are involved in
processes such as inflammation, pain modulation, regulation of blood flow, and the induction of
labor.
What is hormone hyposecretion? - Answers Hormone hyposecretion is the underproduction of
hormones, which can lead to various disorders depending on the hormone affected.
