Match four of the hormones of the negative feedback numbered above with their function given below. Function: Hormone: Stimulates the release of testosterone Answer Inhibits the release of FSH Answer Stimulates spermatogenesis Answer Stimulates the development of secondary sex characteristics Answer;

What is the primary role of FSH in males?     Develop and maintain secondary sex characteristics   Initiate sperm production in the testes   Stimulate the interstitial cells to produce testosterone   Stimulate the nurse cells to produce inhibin   Influence sexual behaviors and sex drive

Compare and contrast the role of estrogens and progesterone.

All cells that have the appropriate receptor show an identical response to a given hormone. False True

Which of the following statements are false regarding the endocrine (hormones) in comparison to the paracrine system? (there may be more than one answer) Hormones are less stable than paracrine signals Hormones have a lower affinity for their receptors than paracrine signals Hormones are produced in a greater quantity than are paracrine signals Hormones are produced by most cell types; paracrine signals are only produced as a response to an insult (wound or infection). Hormones are produced from cells at a greater distance to their response elements than paracrine signaling.

Which of the following statements regarding pituitary hormones is FALSE? Group of answer choices Luteinizing hormone, an anterior pituitary hormone, triggers ovulation of an egg from the ovary and causes the ruptured follicle to produce progesterone and some estrogens. Antidiuretic hormone, released by the posterior pituitary, causes urine volume to increase and blood volume to decrease The hypothalamus makes oxytocin and antidiuretic hormone, which are transported the posterior pituitary for storage. Hyposecretion of follicle-stimulating hormone or luteinizing hormone leads to sterility in both males and females.

A reproductive hormone that is secreted directly from the anterior pituitary is  follicle-stimulating hormone. progesterone. testosterone. estradiol. gonadotropin-releasing hormone.

Select the two different ways that chemicals that might cause problems with sexual development and reproduction work - Estrogen mimics disrupt the endocrine system by attaching to molecules that except the hormone estrogen - estrogen prevents testosterone from developing. - hormone blockers keep certain hormones from attaching to their receptors. - hormone blockers help certain hormones attach to their receptors.

Which of the following terms refers to a hormone interaction that makes the target cell responsive to or more responsive to a second hormone?   Group of answer choices   Antagonistic   Additive   Permissive   Synergism

Which hormone may be in high concentrations in the hypophyseal portal vein?   oxytocin    gonadotropin releasing hormone (GnRH)          melanocyte stimulating hormone (MSH)
