Structure and Function•Pituitary gland•Thyroid gland•Parathyroid•Adrenal glands•Pancreas•Pineal and thymus glands•Ovaries and testes (part of reproductive and endocrine systems)

3

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

4

14 ENDOCRINE SYSTEM


•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

5

14 ENDOCRINE SYSTEM


•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

6

14 ENDOCRINE SYSTEM



• 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

7

14 ENDOCRINE SYSTEM



• Posterior lobe (neurohypophysis) — secretion of two hormones • Antidiuretic hormone (ADH), also called vasopressin

within the brain just behind the thalamus• Secretion of melatonin, which influences the

maturation of sexual organs during puberty

lungs• Withering away during puberty, leaving adults

with fat and connective tissue in its place• Secretion of thymosin, which plays a role in
