Chapter 42, Problem 1ITD
Summary Introduction
To review:
The mechanism through which the level of growth hormone changes over the 24-h period and the process through which it is related to sleep period.
Introduction:
Growth hormone is also known as somatotropin. It is a peptide hormone that enhances growth, cell regeneration, and cell reproduction. Therefore, it plays a significant role during the development of humans and other animals. This hormone is synthesized, stored, and secreted by the somatotropic cells. The somatotropic cells are present within the lateral wings of the anterior pituitary.

Oxytocin is a reproductive hormone associated with parturition and lactation. A research study examined the blood serum levels of oxytocin in patients who have Type 2 diabetes and those with normal blood glucose levels. Each group was then subdivided into normal weight patients and obese patients. The levels of oxytocin were found to be lower in the obese patients with Type 2 diabetes than in the normal weight patients with normal blood glucose levels.Select the FOUR possible side effects that a lower level of oxytocin may have on a patient.

Decreased levels of prostaglandins
Increased movement of milk into the breast
Decrease movement of milk into the breast

- Researchers measured prolactin and growth hormone in the blood plasma of six subjects at regular intervals over a 24-hour period. The investigators were interested in determining if the levels of these two hormones cycle over a 24-hour period. The Figure presents the results of their experiments, with the y axis values showing the amount of each hormone expressed as a percentage of the 24-hour mean value, and each point showing the average of the six subjects levels. FIGURE Mean concentrations of prolactin and growth hormone in plasma, averaged for six subjects and expressed as a percentage of the average concentrations measured for the 24-hour period. Do the results support the hypothesis that the changes in prolactin level over a 24-hour period are associated with the sleepwake cycle? Source: From J. F. Sassin et al. 1972. Human prolactin: 24-hour pattern with increased release during sleep.

This gland produces a variety of hormones with different effects. Among these are a heterogeneous group of hormones called tropic hormones, which directly stimulate the secretion of other hormones from downstream endocrine glands. Which of the following are tropic hormones? Select all that apply. LH Prolactin Oxytocin ACTH TSH testosteronearrow_forwardPlace the following steps (showing how a steroid hormone changes the activities of its target cells) in order of what happens first, second, third, fourth, and last. Refer to image. The hormone-receptor complex enters the nucleus of the cell and binds to the DNA. The steroid hormone passes through the cell membrane. The hormone attaches to a receptor in the cytoplasm, forming a hormone-receptor complex. A gene in the DNA is activated, and transcription and translation take place. Proteins that alter the cell′s activities, such as enzymes, are made. 2. Place the following steps (showing how a hydrophilic hormone changes the activities of its target cells) in order of what happens first, second, third, and last. Refer to image. The activity of the target cell is changed by the final enzyme in the cascade. The second messenger activates or deactivates certain enzymes in a cascade fashion. A second messenger is activated. Hormone binds to a receptor protein.arrow_forward
