1			How is the endocrine system related to the nervous system?
			A)	The two systems interact to regulate activities of other body systems, thus maintaining homeostasis.
			B)	The two systems are different in males and females.
			C)	The two systems interact to regulate activities of most other body systems, thus contributing to homeostasis.
			D)	The two systems work in opposition to each other through a system of negative feedback mechanisms.
2			Hormones related to the reproductive system are secreted by
			A)	only the anterior pituitary.
			B)	only the posterior pituitary.
			C)	both the anterior pituitary and the posterior pituitary.
			D)	neither the anterior pituitary nor the posterior pituitary.
3			The human reproductive system is the only body system that is adapted
			A)	more for the survival of the species than for the well-being of the individual.
			B)	to encourage cellular reproduction by mitosis rather than meiosis.
			C)	to prevent the transmission of sexually transmitted infections (STIs).
			D)	to limit its organs and its biochemical pathways only females of the species.
4			Estrogen and progesterone are
			A)	hormones secreted by the testes.
			B)	glands secreted by the ovaries.
			C)	neurosecretory cells secreted by the ovaries.
			D)	hormones secreted by the ovaries.
5			The anterior pituitary releases human growth hormone (hGH), which
			A)	stimulates fat metabolism and targets the liver to release hormones that stimulate protein synthesis and the growth of muscles and bones.
			B)	is regulated by thyroid-stimulating hormone (TSH).
			C)	produces calcitonin, which helps lower blood calcium levels.
			D)	secretes aldosterone, which stimulates the kidneys to absorb sodium, thus increasing blood pressure, until secretion is halted by a negative feedback mechanism.
6			Follicle-stimulating hormone (FSH) stimulates the production of mature reproductive cells
			A)	only in women.
			B)	in both men and women.
			C)	only in men.
			D)	in both sexes, from puberty until the end of life.
7			How are hormones transported to their target cells throughout the body?
			A)	They are released from ducts at various locations near specific organs.
			B)	They are transported by diffusion.
			C)	They are secreted into specialized organs.
			D)	They are secreted directly into the bloodstream.
8			Hormones that stimulate endocrine glands to produce other hormones are called
			A)	trigger hormones.
			B)	tropic hormones.
			C)	trophic hormones.
			D)	topographic hormones.
9			Many hormones are regulated by
			A)	sensory and motor neurons.
			B)	neurotransmitters.
			C)	negative feedback mechanisms.
			D)	homeostasis.
10			The hypothalamus controls the secretions of the anterior pituitary and, thus, various endocrine glands. Which two hormones are produced directly by the hypothalamus?
			A)	oxytocin and TSH (thyroid-stimulating hormone).
			B)	ADH (antidiuretic hormone) and hGH (human growth hormone).
			C)	oxytocin and hGH (human growth hormone).
			D)	oxytocin and ADH (antidiuretic hormone).
