To describe:
The structure, function of the hypothalamus-pituitary complex.
Introduction:
The anteroinferior region of diencephalon is known as the hypothalamus. There is a stalk-like structure known as the infundibulum which extends from the hypothalamus. This helps in attaching to the pituitary gland.
To describe:
The way through which releasing hormones control hormonal secretion from cells of the anterior pituitary.
Introduction:
The neurosecretory cells produce six different regulatory hormones which can be either releasing or inhibiting hormones.
To describe:
Hormones of the anterior pituitary and their functions.
Introduction:
The pituitary gland is a small organ of the endocrine system, which is also known as the master gland. It secretes many hormones that travel through the bloodstream and direct various processes. The pituitary gland is comprised of three lobes, namely-anterior, posterior, and intermediate.

- A physician sees a patient whose symptoms include sluggishness, depression, and intolerance to cold. After eliminating other possible causes, the doctor diagnoses a hormone problem. What disorder fits the symptoms? Why does the doctor suspect that the underlying cause is a malfunction of the anterior pituitary gland?arrow_forwardIdentify the two hormones released from the posterior pituitary, their target cells, and their principal actions.arrow_forwardExplain 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_forward
- State what the different parts of the pituitary gland are called and how they differ. b) Explain the physiological significance of the portal system of the hypothalamus and pituitary gland c) What hormones are produced by different parts of the pituitary gland? Enter in the image below. What effects do these hormones have on the body? Give at least one example of a function for each hormone.arrow_forwardList all hormones secreted/produced by the anterior and posterior pituitary glands. State their function and whether they are amino based, peptide, or steroid.arrow_forwardDiscuss the interaction and functions of the Hypothalamic and Anterior Pituitary Hormones.arrow_forward
- Know which hormone is released by the hypothalamus and which is released by the anterior pituitary. Know whether the hypothalamic hormone is a releasing or inhibiting hormone. What are the targets in the body of the anterior pituitary hormones and what do those targets secrete? What is the final target and response? Make sure you know both the abbreviations and the full names of the hormones. Dopamine, prolactin Somatostatin, GHRH, GH, insulin-like growth factors TRH, TSH, thyroid hormone CRH, ACTH, and cortisol GnRH, FSH, LH, estrogen, progesterone, testosteronearrow_forwardDescribe the embryonic origins of the adenohypophysis and neurohypophysis, and list theparts of each. Which of these parts is also called the anterior pituitary? Which is called the posterior pituitary?arrow_forwardList the hormones produced by the two lobes of the pituitary gland and state their functions?arrow_forward
- Identify the glands recognised as components of the endocrine system. Understand the difference between endocrine and exocrine glands. Describe the anatomical relationship between the hypothalamus and pituitary gland Distinguish between the neurohypophysis (posterior pituitary) & the adenohypophysis (anterior pituitaryarrow_forwardName seven hormones produced by the anterior pituitary gland. Why are four of these seven hormones called “tropic hormones”? Explain how neurosecretory cells in the hypothalamus control secre-tion of hormones by the anterior pituitary gland.arrow_forwardDescribe the location and structure of the pituitary gland.arrow_forward
