- Hypothalamo- hypophyseal tract Stalk Neurohypophysis Posterior lobe Pars tuberalis Anterior lobe Adenohypophysis Pituitary gland
- Slide 7
- Fig. 18.4a(TE Art) Hypothalamohypophyseal tract Posterior lobe Paraventricular nucleus Supraoptic nucleus Oxytocin ADH Anterior lobe Oxytocin = uterus & mammary glands Antidiuretic hormone = kidneys
- Slide 8
- Superior hypophyseal artery Posterior pituitary Anterior pituitary Releasing hormones go and do something hormones
- Slide 9
- Fig. 18.6(TE Art) Growth hormone ACTH TSH prolactin Liver Fat, muscle, bone LH FSH TRH GnRH CRH Hypothalamus Adrenal cortex OvaryTestis Thyroid Mammary gland IGF
- Slide 10
- Fig. 18.10a(TE Art) Adrenal gland Kidney Adrenal cortex Adrenal medulla epinephrine norepinephrine
- Slide 11
- Adrenal gland Kidney Adrenal cortex mineralcorticoids glucocorticoids sex steroids Adrenal medulla Aldosterone (mineralcorticoid): kidney = retain Na, excrete K (water retained, BP) Cortisol (glucocorticoid): fat & protein breakdown, glucose synthesis, fatty acid & glucose release into blood, help body adapt to stress, repair damaged tissues Dehydroepiandrosterone (DHEA): weak testosterone = libido, 2 nd sex characteristics
- Slide 12
- Cushings Syndrome adrenal cortex hypersecretion of cortisol
- Slide 13
- Thyroid Thymus Trachea
- Slide 14
- Thyroid gland Follicular cells: T3 & T4 increase metabolic rate C cells: calcitonin inhibits osteoclasts..
- Slide 15
- Pharynx Thyroid gland Esophagus Parathyroid glands Trachea Detect low calcium Secrete PTH increase Ca absorption inhibits Ca excretion stimulates osteoclasts Posterior view

- Slide 17
- Pancreatic islet cell-- insulin cell -- somatostatin cell -- glucagon Insulin: controls glucose transport into cells Diabetes Type I: low or no B-cells, no insulin Diabetes Type II: insulin insensitivity (receptor) hyperglycemia emaciation atherosclerosis (fatty deposits) ketoacidosis (low blood pH) = coma, death
