A. Pituitary gland
B. Thyroid gland
C. Adrenal Glands
D. Reproductive Glands

During the final stages of human gestation, receptors for the hormone oxytocin increase on the smooth muscle cells of the uterus. The release of oxytocin during labor stimulates the smooth muscle tissue in the wall of the uterus. The strong contraction of the smooth muscle in the uterus helps push the baby through the birth canal so that delivery can occur. This process requires the interaction of which organ systems are together to produce this response?
A. Endocrine and muscular only
B. Endocrine and reproductive only
C. Endocrine, muscular, and reproductive
D. Endocrine, reproductive, and excretory
Which of the following structures is considered the basic functioning unit of the nervous system and is comprised of a cell body, dendrites, and axons?
C. Brain stem
