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_forwardExplain the negative feedback loops that regulate the production and release of anterior pituitary hormones.arrow_forwardIdentify the two hormones released from the posterior pituitary, their target cells, and their principal actions.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_forwardExplain how the hypothalamus regulates the release of the two hormones from the posterior pituitary gland, and describe the general functions of each.arrow_forward
