Colloid: acellular pink material surrounded by simple cuboidal cells Thyroid follicles Cells between the follicles: Parafollicular cells

Adrenal cortex produces this group of hormones

Corticosteroids

Gland that increases blood pressure and heart rate when the body experiences stress

Adrenal medulla (epi and norepi)

Hypothalamus; thyrotropin-releasing hormone

This hormone is released in the hypophyseal portal system and travels to the ______ ______ _______ causing the release of this hormone ______

Anterior pituitary gland; TSH

This hormone is released into the general circulation and travels to the ______ _____, causing the release of T3/T4

Thyroid gland
