a.
To design: A reflex map with feedback loops for hypercortisolism caused by an adrenal tumor.
Introduction: The main causes of hypercortisolism are an adrenal tumor, pituitary tumor, and excess secretion of cortisol.
b.
To design: A reflex map with feedback loops for hypercortisolism caused by a pituitary tumor.
Introduction: Hypercortisolism caused by a pituitary tumor is known as secondary hypercortisolism.
c.
To design: A reflex map with feedback loops for hyperthyroidism caused by a thyroid tumor.
Introduction: Hyperthyroidism refers to a condition in which an individual’s thyroid gland secretes too much thyroid hormone.
(d)
To design: A reflex map with feedback loops for hypothyroidism caused due to a pituitary problem.
Introduction: The failure of the pituitary gland to secrete TSH (thyroid stimulating hormone) causes secondary hypothyroidism.

- Activity Direction: Answer the following question. 1. What is the Endocrine system? 2. Define Hyperthyroidism and explain why one of its symptoms is weight loss. 3. What is the primary role of the parathyroid gland? 4. How do hormones differ from the nervous system? 5. How many hormones are secreted by the anterior lobe of the pituitary gland?arrow_forwardBriefly explain MoA of non-steroid hormones.arrow_forwardHormone Exploration: Go to https://www.yourhormones.info/hormones Now that you have explored some of the endocrine system organs, find out where the following hormones are produced. Complete the table.

- Matching 1. Match the hormone on the left with its function on the right. ADH a. decreases blood sugar b. increases thyroid hormone secretion c. regulates cell metabolism d. increases steroid release e. increases uterine contractions f. decreases urination g. prolongs sympathetic response h. stimulates tissue growth i. increases blood sugar j. increases milk production in females insulin - glucagon oxytocin epinephrine thyroxine - prolactin _ACTH (adrenocorticotropic hormone) TSH - growth hormonearrow_forwardExplain how neurotransmitters work. Distinguish between neurotransmitters and hormones, and discuss one example of each found in the human body, describing how each works.arrow_forwardCreate a hormone map. A complete map will include the secretion signal for the hormone, the origin of the hormone, and hormone targets, and the physiological outcomes of hormone increases or decreases within the body. Be sure to indicate feedback loops within your map. Please provide an explanation of the steps within your map and explain why this interaction is important physiologically.arrow_forward
- Briefly explain the MoA of steroid hormones.arrow_forwardExercise Exercise places demands on the body. Cells require extra energy and water is lost through sweating. The breathing rate and heart rate increases during exercise to deliver more glucose and oxygen to cells which are converted to ATP through cellular respiration. Identify three hormones that are involved in re-establishing homeostasis after an intense workout and explain why they are involved.arrow_forwardDescribe all the sources of amplification in the insulin receptor system.arrow_forward
- Explain the concept of coordination in the context of endocrine system function. Differentiate exocrine from endocrine glands. Describe the roles of the hypothalamus, pituitary glands, target glands, and target organs. Enumerate the secretion of the hypothalamus and their functions. List the hormones secreted by the anterior and posteriors pituitary glands and their functions. Explain the hormonal secretion and their functions of the following: thyroid, parathyroid, adrenal (cortex and medulla), gonads (testis, ovaries), pancreas (beta and alpha cells), thymus, pineal glands. Describe the functions of hormones secreted by the following internal organs: heart, liver, kidney, stomach, small intestines, colon, and muscles Explain the concept of negative and positive feedback. Describe drugs that affect the endocrine system: thyroid replacement hormones, steroids, insulin. Give examples of nursing diagnosis that apply to issues of the endocrine system.arrow_forwardA patient with parathyroid deficiency 10 days after inadvertent damage to the parathyroid glands during thyroid surgery would probably have A. a low plasma calcium level, increased membrane permeability to sodium, increased muscular excitability, and muscle spasms or twitching. B. a high plasma calcium level, decreased membrane permeability to sodium, and bone demineralization. C. low plasma phosphate and calcium levels, decreased muscular excitability, and bone demineralization. D. a high plasma calcium level, increased muscular excitability, and bone demineralization. E. a low plasma calcium level, decreased membrane permeability to sodium, increased muscular excitability, and muscle spasms or twitching.arrow_forwardDescribe the synthesis of peptide hormones.
