Question

What does the follicle-stimulating hormone (FSH) do?

A. Follicle-stimulating hormone is secreted by the hypothalamus in response to gonadotropin-releasing hormone sent from the gonads. FSH induces ovulation.

B. Follicle-stimulating hormone is secreted by the anterior pituitary in response to gonadotropin-releasing hormone sent from the hypothalamus. FSH induces gamete development.

C.Follicle-stimulating hormone is secreted by the posterior pituitary in response to leutenizing hormone sent from the hypothalamus. FSH induces Leydig cell formation.

Which of the following is true endocrine tissue (as opposed to nervous tissue)?

A.hypothalamus

B. antierior pituitary

C. posterior pituitary

You are assessing a patient who presented with intersex genitalia. You find that this individual is genetically male (has one X chromosome and one Y chromosome) and possesses the testis-determining factor (called the SRY gene). Further, they are producing adequate levels of gonadotropin-releasing hormone, follicle-stimulating hormone, and testosterone. What is the most likely explanation for this individual’s intersex genitalia?

A.absent or inactive testosterone receptors

B.hyposecretion at the level of the hypothalamus

C. hyposecretion at the level of the testes

D. hypersecretion at the level of the pituitary gland

In a complex endocrine pathway, long- loop negative feedback inhibits

A.then hypothalamus and/or the anterior pituitary

B.the primary endocrine gland

C.the target tissue

An unknown hormone is synthesized in the hypothalamus and released from the posterior pituitary. This hormone is released in increasing levels as the posterior pituitary is repeatedly stimulated by feedback from the body. This hormone must be a __ and is part of a ____.

A.neurohormone, negative feedback loop

B. steroid hormone, positive feedback loop

C. neurohormone, positive feedback loop

D. catecholamine, negative feedback loop

Hormones act on target cells by controlling:

A.rates of enzymatic reactions

B.transport across cell membranes

C.gene expression and protein synthesis

D.B and C

E.A, B, and C

All of the following are characteristics of hormones EXCEPT

A.They only elicit a response at the target tissue/cell

B.They travel to target cells through the blood

C.They must circulate in high concentrations to elicit an effect

When a chemical messenger operates through a second messenger system:

A.The chemical messenger must travel through the first (cell) membrane as well as the second (nuclear) membrane

B.The chemical messenger changes to a second class when bound to the membrane receptor

C. The cell membrane receptor must communicate with the rest of the cell through action of a second protein.

A messenger molecule binds a cell membrane receptor which activates __ leading to a signal cascade. This is an example of a ___ hormone.

A.cyclic-AMP, steroid

B.G-protein, peptide

C.cyclic-AMP, thyroid

D.G-protein, catecholamine

E.B or D

Which is NOT an example of negative feedback?

A.uterine contractions during childbirth

B.regulating body temperature

C.regulating blood sugar

Each of the following is true about cell membranes except

A.the lipid:protein ratio varies widely depending on the metabolic activity of the cell.

B.phospholipids are arranged with hydrophobic ends facing the extracellular space.

C.has receptors for communication.

D.phospholipids, glycoproteins, and cholesterol are all found in cell membranes.

The most common tissue type is Blank . This tissue supports, connects, protects, strengthens, and insulates other tissues.

Answer 1

1. Answer: Option B is correct
Explanation:
FSH is secreted by the anterior pituitary gland in response to GnRH sent from the hypothalamus.
FSH induces ovule development by inducing the secretion of estrogen.

2. Answer: Option B is correct
Explanation:
The anterior pituitary gland is considered the true endocrine gland. It is also considered as the master endocrine gland.
Oxytocin and Vasopressin are secreted by the hypothalamus and stored in the posterior pituitary gland.
