A&P II CHAPTER 18 HW

The hormones produced by the indicated endocrine structure are renin, ______ , and calcitriol.

erythropoietin (EPO)

The principal action of the hormone produced by the indicated endocrine structure is to promote secretion of ______ juice and increase movements of the _______.

gastric, stomach

The hormone produced by the indicated endocrine structure is

gastrin

Cortisol stimulates

gluconeogenesis

Insulin helps stabilize blood glucose levels by

increasing transport of glucose into cells

Which of the following is not a true statement?

most hormone systems function under a positive feedback system

Which gland is divided into two distinct functional units?

pituitary

A example of a negative feedback loop would be the release of a hormone in response to a single stimulus. the release of glucagon in response to low blood sugar. the release of oxytocin in response to stretching of the uterus. All of these.

the release of glucagon in response to low blood sugar.

A example of a positive feedback loop would be the release of a hormone in response to a single stimulus. the release of glucagon in response to low blood sugar. the release of oxytocin in response to stretching of the uterus. All of these.

the release of oxytocin in response to stretching of the uterus.

What is the sequence of events that occur for the anterior lobe of the pituitary gland to release hormones into the bloodstream? 1. Releasing hormones attach to endocrine cells in the anterior pituitary gland 2. Releasing hormones are secreted from neurosecretory cells in the hypothalamus 3. Endocrine cells in the anterior pituitary gland to release their specific hormone into the bloodstream 4. Releasing hormones travel through the hypophyseal portal system to the anterior pituitary gland 5. Hormones exit the anterior lobe of the pituitary gland into the systemic circulation

2, 4, 1, 3, 5

Which of the following organs is/are incorrectly matched with the hormones they secrete? 1. Kidneys - Renin 2. Placenta - Human chorionic gonadotropin 3. Adipose tissue - Leptin 4. Heart - Atrial natriuretic peptide 5. Pancreas - Glucose-dependent insulin tropic peptide 6. Gastrointestinal tract - Cholecystokinin

5 is incorrectly matched

An increase in the blood osmotic pressure will stimulate the release of

ADH

Corticotropin-releasing hormone causes the appropriate endocrine cells in the anterior lobe of the pituitary gland to release

Adrenocorticotropic hormone

Human growth hormone released during a Resistance Reaction will cause the release of energy from stored fats. the release of glucagon in response to low blood sugar. increased cell expansion and growth. All of these.

All of these

When PTH binds to kidney cells Calcitriol is released. Calcium uptake in the intestines increases. Blood calcium levels increase. All of these.

All of these

The control of the release of hormones from the anterior lobe of the pituitary gland is by the

Hypothalamus

In hypothyroidism.

Iodine deficiency is the most common cause of primary hypothyroidism

What is the purpose of the hypophyseal portal system?

It ensures the concentration of releasing or inhibiting hormones from the hypothalamus to the anterior lobe of the pituitary gland remain high.

Hormones released from the posterior lobe of the pituitary gland are produced by

Neurosecretory cells whose cell bodies are in the hypothalamus but whose terminal ends are in the posterior lobe where they release their hormones

How do releasing or inhibiting hormones released from the hypothalamus reach the anterior lobe of the pituitary gland?

They pass through a set of portal veins that run exclusively from the hypothalamus to the anterior lobe of the pituitary gland.

Prostaglandins, and leukotrienes are found in virtually all body cells except red blood cells and act as paracrines or autocrines in response to chemical or mechanical stimuli.

True

Paracrines

act on the neighboring cell

The hormone produced by the indicated endocrine structure is Enter your answer in accordance to the question statement

atrial natriuretic peptide (ANP)

The principal actions of the hormones produced by the indicated endocrine structure are to be part of a sequence of reactions that raises ______ (effect of renin); increase the rate of ______ cell formation (effect of erythropoietin); and aid in the absorption of dietary calcium and phosphorus (effect of calcitriol).

blood pressure, red blood

The principal action of the hormone produced by the indicated endocrine structure is to decrease

blood pressure.

Releasing hormones from the hypothalamus are carried to the anterior pituitary

by the hypophyseal portal vein

Which of the following is not true of the prostaglandins?

Decrease pain sensitivity

Which type of cells in the anterior lobe of the pituitary gland produces hormones that affect reproductive functions in the male testes or female ovaries?

Gonadotrophs cells

Which hormone uses a second messenger mechanism?

Norepinephrine

What are the hormones produced by the posterior lobe of the pituitary gland?

Oxytocin and antidiuretic hormone
