Structure and Function (continued)
14 ENDOCRINE SYSTEM Structure and Function (continued) Consisting of endocrine (ductless) glands Secretion of chemicals called hormones directly into the bloodstream Control and integration of many bodily functions Action of hormones on target organs to increase or decrease the target’s activity level Monitoring and interpretation of and reaction to changes in the body and external environment to maintain homeostasis 3 3

14 ENDOCRINE SYSTEM Structure and Function (continued) Pituitary gland (hypophysis) Tiny, pea-shaped structure at the base of the brain Consists of an anterior and posterior lobe Known as the “master gland” of the body Regulation of many body activities Stimulation of other glands to secrete their own specific hormones Effects of its hormones felt throughout the body 4 4

14 ENDOCRINE SYSTEM Structure and Function (continued) Pituitary gland (continued) Anterior lobe (adenohypophysis) — secretion of six hormones Adrenocorticotropic hormone (ACTH), which regulates the production of steroid hormones by the adrenal gland Follicle-stimulating hormone (FSH), which stimulates egg production in the ovaries or sperm production in the testes Growth hormone (GH), also called somatotropin, which regulates growth of bones and other tissues 5 5

14 ENDOCRINE SYSTEM Structure and Function (continued) Pituitary gland (continued) Anterior lobe (adenophypophysis) — secretion of six hormones (continued) Luteinizing hormone (LH), which stimulates production of sex hormones by the ovaries or testes Prolactin, which stimulates growth of breast tissue and milk production in females Thyroid-stimulating hormone (TSH), which regulates activity of the thyroid gland 6 6
