PHTY200 Lecture Notes - Lecture 8: Parathyroid Gland, Pituitary Gland, Hyperfunction
Document Summary
Topic 8: disorders of endocrine control and growth and metabolism. Disorders of endocrine control of growth and metabolism. 8. 1 describe the role of the hypothalamus in regulating pituitary control of endocrine function (revision - may not be covered in lecture: endocrine glands include. 8. 2 describe the mechanisms of endocrine hypofunction and hyperfunction: hypofunction: this is the underproduction of hormones, causes include. Disruption to blood flow, infection, inflammation, autoimmune. Injury to glandular cells responses, neoplastic growth or invasive tumour growth. Atrophy as the result of drug therapy or unknown reasons. Receptor defects: hyperfunction: this excessive hormone production, causes include. Excessive stimulation and hyperplasia or hypertrophy of the endocrine gland hormone-producing tumour of the gland. Interface between nervous system and endocrine system: anterior pituitary is controlled by releasing hormones secreted from the hypothalamus (travel via the portal vein, result in the release of many hormones that control. Non functional tumours do not secrete hormones: pituitary surgery or radiation, lesions and head trauma.
