Hypothalamus And Pituitary Notes

Medicine Notes > Endocrinology Notes

This is an extract of our Hypothalamus And Pituitary document, which we sell as part of our Endocrinology Notes collection written by the top tier of University Of Leicester students.

The following is a more accessble plain text extract of the PDF sample above, taken from our Endocrinology Notes. Due to the challenges of extracting text from PDFs, it will have odd formatting:

Hypothalamus and Pituitary HypothalamusGonadotrophin-releasing hormone GnRH Dopamine Growth hormone releasing hormone (GHRH) Thyrotrophin-releasing hormone (TRH) Corticotrophin-releasing hormone (CRH) Vasopressin (ADH) Oxytocin

Site
- Base of brain around the third ventricle and above the pituitary stalk
- Hypophyseal-portal blood supply carried in pituitary stalk
- Optic chiasm lies just above pituitary fossa - so any expansion can lead to visual field defects (tunnel vision)
