C) salivary glands
Which of the following is NOT an endocrine gland?
A) pancreas
B) adrenal glands
C) salivary glands
D) thyroid gland
E) pituitary gland
C) some endocrine glands have additional non-endocrine functions
Which of the following is true of endocrine glands?
A) endocrine glands are located very close to their target organs to be more effective
B) each endocrine gland only produces one hormone
C) some endocrine glands have additional non-endocrine functions
D) each endocrine gland is independent and not affected by another endocrine gland
E) none of the choices are correct
E) hormones are directed to the target organ and avoid contact with non-target cells
Which of the following is NOT correct about hormones?
A) hormones are generally found across the animal kingdom

B) When the blood becomes dilute, ADH is no longer released from the hypohalamus
Which is an example of negative feedback?
A) Nursing action stimulates the hypothalamus to release oxytocin that triggers mammary gland milk production/
B) When the blood becomes dilute, ADH is no longer released from the hypohalamus
C) Uterine stretching sends nerve impulses to the hypothalamus that releases oxytocin that triggers uterine contraction
D) FSH and LH stimulate the gonads to produce sperm or eggs
E) TRH stimulates he anterior pituitary to release thyroid-stimulating hormone
D) releasing hormones
The hypothalamus controls the anterior pituitary via
A) nerve stimulation?
B) blood osmotic concentrations
C) blood glucose concentrations
D) releasing hormones
E) ACTH
E) Oxytocin both causes the uterus to contract in labor and stimulates the release of milk from mammary glands, which is reinforced by prolactin
Consider the synchronization of birth and milk production. Babies can be born several months prematurely, and milk production is needed immediately after birth. How has the human body evolved to coordinate this delicate timing of events?
A) The ovaries signal the rest of the body tissues by varying the level of estrogen
B) Conscious awareness of the arrival of a baby triggers the mother's hypothalamus to secrete prolactin
C) The hypothalamus and pituitary that triggered the female reproductive cycle also schedule milk production on a nine-month clock basis
D) ADH produced by the baby passes through the placenta and, added to the mother's ADH, builds up her milk production relative to the size of the fetus
E) Oxytocin both causes the uterus to contract in labor and stimulates the release of milk from mammary glands, which is reinforced by prolactin from the pituitary
