Endocrine Anatomy Flashcards
What is the pituitary gland divided into?
Anterior and posterior pituitary gland
What is the blood supply to the pituitary gland and where does it originate from?
Internal carotid artery.
Superior and inferior hypophysial artery
Blood supply to the posterior pituitary gland?
Inferior hypophysial artery
Blood supply to the anterior pituitary gland?
Superior hypophysial artery
Anterior pituitary gland cells, what colour do they stain and what do they produce?
Acidophil, stains pink - somatotroph (GH) and mammotroph (prolactin)
Basiphil, stains purple - gonadotroph (FSH, LH), corticotroph (ACTH), thyrotroph (TSH)
