Glands of the Endocrine System

Location Directions: Label the glands on the body

Pituitary Gland Hormone Target Cell/Tissue Effect on Target Cell/Tissue Follicle Stimulating Hormone (FSH) Ovaries & testes Stimulates production of mature eggs & sperm Luteinizing Hormone (LH) Prepares uterus for implantation of fertilized egg Thyroid Stimulating Hormone (TSH) Thyroid gland Stimulates production of thyroxine Adreno-corticotropic hormone (ACTH) Kidney Release hormones from kidney cortex Human Growth Hormone (HGH) Cells throughout body Stimulates growth Melanocyte-stimulating hormone (MSH) Skin Stimulates melanin pigment Prolactin Mammary glands Produce breast milk

Pituitary Gland: Cont’d Disease- Human growth hormone deficiency Cause: Hyposecretion of HGH Treatment: Growth hormone injections

Hypothalamus Hormones secreted Target Cells/Target Tissue Effect on Target Cells/Target Tissue ADH Kidney Absorbs water Oxytocin Uterus Causes contractions

Pineal Gland Hormone Secreted Target Cells/Tissue Effect on Target Cells/Tissue Melatonin Thyroid & Adrenal Cortex Cause sleepiness Circadian Rhythm Disease Name: SAD (seasonal affective disorder) Cause: Hypersecretion of melatonin Symptoms: Weight gain, depression, fatigue Treatment: Sun lamp

Thyroid Hormone Secreted Target Cells Effect on target cells Thyroxine Cells throughout body Primary regulation of metabolism Calcitonin Kidney, S.I. & bone Maintain calcium balance Diseases Hyperthyroidism Cause: Hypersecretion of thyroxine Symptoms: Bulging eyes, hair loss, shakiness Treatment: Surgery Hypothyroidism Cause: Hyposecretion of thyroxine Symptoms: Fatigue, depression Treatment: Thyroxine supplement

Parathyroid Hormones Secreted Target Cells/Tissue Effect on Target Cells/Tissue Parathyroid hormones (PTH) Bones Primary gland to control calcium levels

Thymus Hormone Secreted Target Cells/Tissue Effect on Target Cells/Tissue Thymosin Lymphatic System (immune system) Promotes development of T cells & lymphocytes (immune system)

Pancreas Hormone Secreted Target Cells/Tissue Effect on Target Cells/Tissue Insulin Liver, skeletal muscle, fat Reduces glucose levels in the blood Glucagon Increases glucose levels in the blood Disease Diabetes mellitus Cause: Hyposecretion of insulin Symptoms: Excessive urination, dehydration, weight loss Treatment: Insulin injections

Adrenal Medulla Hormone Secreted Target Cells/Tissue Effect on Target Cells/Tissue Corticosteroids Heart & digestive system Regulate blood volume & pressure Control metabolism of food Epinephrine Heart & lungs Increase heart rate & blood pressure Enlarge air passageways Norepinephrine

Adrenal Medulla: Cont’d Disease Addison’s Disease Cause: Hyposecretion of adrenal gland Symptoms: Weakness, fatigue, dizziness Treatment: Corticosteroids & fluids

Testes Hormone Secreted Target Cells/Tissue Effect on Target Cells/Tissue Testosterone Bones & muscles, vocal cords, sweat glands, brain Secondary male characteristics

Ovaries Hormone Secreted Target Cells/Tissue Effect on Target Cells/Tissue Estrogen Breast, brain, bone, liver, heart Female secondary sex characteristics Progesterone Uterus Builds uterine lining
