BIO310H5 Lecture Notes - Lecture 11: Pars Tuberalis, Pars Intermedia, Posterior Pituitary
Document Summary
Secretes 9 hormones that control other glands. Both parts controlled by neurosecretory cells of the hypothalamus (part of the brain) It has a very critical function in regulation of other endocrine glands via hormonal stimulation. There is a hormone secreted by endocrine gland aka pituitary and it circulates and stimulates or inhibits functions of other endocrine glands. Hypothalamus is a big gland on the brain on both sides of 3rd ventricle and it is a small area and is connected by the infundibular stalk. 2 major parts of the gland; anterior lobe and posterior lobe. Anterior lobe has 3 subdivisions; pars tuberalis is connected to infundibular stalk, pars distalis is the distal part, pars intermedia is the intermediate part. Function is to secrete chemical messengers which are exocytosis the same way as nt but in this case these molecules are secreted to the bloodstream.
