Chapter 42, Problem 15TYK
Summary Introduction
To review:
The endocrine system that evolved earlier, endocrine glands or neurosecretory neurons.
Introduction:
The endocrine system can be defined as the system that is composed of chemical messengers known as hormones and glands. The endocrine system consists of groups of glands that secrete hormones in the bloodstream. These hormones regulate the functions of the target sites. The activity of these hormones is regulated by a feedback mechanism.

Study each picture that depicts the involvement of a particular gland in the endocrine system. Write down the name of the endocrine gland and explain its effect, according to its function. Please use the table attached as reference on your choices, thanks!
Which of the following would be better handled with an endocrine system response (not a nervous system response) and why:
A.
Assessing a noise in your environment (such as the hum of an air conditioner), and adapting to it (so you no longer unnecessarily pay attention to something unimportant).
B.
Stimulating the gradual development (it takes days!) of follicles in the ovary, because hormonal signals have a more extended duration than a nervous system signal.
C.
Both choice A and choice B
D.
Neither A nor B.
Enumerate 5 hormones that you are familiar with and their roles in the body.
List 3 things to learn more about the endocrine system and why.

- Which of the following statements is not true of the endocrine system? Select one: A. Most of its components are not anatomically connected, unlike most other systems of the body. O B. It is one of two major regulatory systems of the body O C. It is an important regulator of homeostatic mechanisms. O D. The nervous and endocrine systems often overlap in function. O E. It is composed of glands that secrete chemical messengers through ducts into the blood.arrow_forwardThe table below lists the functions of many of the hormones you have studied.

- Make a table about endocrine system Gland | Hormone | Target organ | Function. Example photo ⬇️arrow_forwardDuring a lecture-discussion about the endocrine system, the hypothalamohypophyseal portal system was taken. Which response, if made by a student, indicates understanding related to the portal system? O "It carries hormone from the hypothalamus to the anterior pituitary." O "It carries hormones from the anterior pituitary to the body." O "It carries hormone from the hypothalamus to the posterior pituitary." O "It carries hormones from the posterior pituitary to the body." 1 2 3 4 6 7 8 N Desktop Cack 46% 10arrow_forwardexplain how hormone release is controlled via nerves, via other hormones or via other substances in the blood. Correctly used / explained the concepts of negative feedback and half-life Describe how different hormones bind to different receptors on the target organ, which can give rise to different responses (stimulating or inhibiting). Explain how small amounts of hormones in the blood have large physiological effects (i.e. cascade effects).arrow_forward
- The feedback pathway for the long-term stress hormone is shown below. Hypothalamus → Releasing Hormone → Gland 1 - → Hormone 1- Gland 2 – Hormone 2 Some Endocrine Structures and Hormones 1. Posterior pituitary 2. Anterior pituitary 3. ADH 4. ACTH 5. Adrenal medulla 6. Adrenal cortex 7. Cortisol 8. Epinephrine Select the number of the structure from the list above that corresponds to the gland or hormone in the long-term stress hormone release pathway. Gland 1 Hormone 1 Gland 2 Hormone 2arrow_forwardThe dexamethasone test involves the administration of a synthetic glucocorticoid. Knowing about negative feedback mechanisms, how do you think this test helps determine the function of the pituitary? Since you couldn't answer one of my questions heres the last one. Describe how steroid hormones, for example cortisol, are metabolized in the body. What are the benefits of using a 24-hour urine test to measure this hormone?arrow_forwardHormone release and regulation is a complex interplay of control systems, feedback pathways and the concentration of circulating substances. Demonstrate your understanding of how negative feedback systems work by considering what would happen if the usual mechanisms no longer applied. You may like to think about an ectopic source of adrenocorticotropic hormone (ACTH), as secreted from a small cell carcinoma of the lung, as an example. In your explanation of how negative feedback systems can be derailed, describe how hormone/s released from the target endocrine organ usually regulate the feedback loop.arrow_forward
- Hello, I do not understand these questions, can I get help with them, please? Below are 3 statements, explain if each is true/false and why (VERY brief statement) #1: A tropic hormone always increases the size of an endocrine gland. #2: Spontaneous action potentials in the heart are primarily triggered by flux of K+ into cells through If channels. #3: Increasing the frequency of action potentials in motor units generates more tension than increasing the number of motor units.arrow_forwardpick an endocrine gland of your interest. Imagine a human being lacking the said endocrine gland. Predict what might happen to the individual. How will the absence of the endocrine gland affect the homeostatic events, growth, development, differentiation and multiplication of the body tissues?arrow_forwardThe Endocrine System can be complex to learn; map out one of the "chains" of three hormones that you learned in the lecture. For example, Hormone 1 is released by X. This targets Y which releases Hormone B, which targets Z and causes Hormone C to be released. (Hint: most of these hormone chains will begin with a Hormone from the Hypothalamus).arrow_forward
