The Hormones of the Endocrine Glands The endocrine system is responsible for many different functions in the body. Hormones are in use in the body all the time! The different hormones, their target cells and their function in that cell are sometimes difficult to understand, and students need to understand this by the end of this unit. This activity may be a help! Each of the following pages contains the information for the endocrine hormones, their target cells and their function. You can print these off on different coloured paper (or change the font for each page), cut them out, and put them into envelopes (keeping each ‘page’ separate). Label each envelope with either ‘hormone’, ‘Target tissue’ or ‘Function’ and the number of pieces in each one (each envelope should have 11 pieces). Students will work in pairs, and have to organize them into what they think are the appropriate answers. When they think they have the order correct, the teacher can look over their answers, and if it is correct, they will write the information into a chart. This will allow the students to have a summary chart for all of these hormones. Releasing and inhibiting hormones Follicle-stimulating hormone (FSH) Prolactin (PRL) Luteinizing hormone (LH) Growth hormone (GH) Thyroid-stimulating hormone (TSH) Adrenocorticotropic hormone (ACTH) Antidiuretic hormone (ADH) Melanocyte-stimulating hormone (MSH) Endorphins Oxytocin Anterior pituitary Melanocytes in the skin of some vertebrates Mammary glands Pain pathways in the nervous system Bone, soft tissue Kidneys Thyroid gland Uterus, mammary glands Adrenal cortex Ovaries in females, testes in males Ovaries in females, testes in males Regulates the secretion of anterior pituitary hormones Stimulates breast development and milk production Stimulates the growth of bones and soft tissues; helps control metabolism of glucose and other fuel molecules Stimulates the secretion and thyroid hormones and the growth of the thyroid gland Stimulates the secretion of glucocorticoids Females: Stimulates egg growth and development, and secretion of sex hormones Males: stimulates sperm production Females: regulates ovulation Males: Secretion of sex hormones Promotes darkening of skin Inhibits the perception of pain Increases blood volume and pressure by increasing water reabsorption in the kidneys Promotes uterine contractions; stimulates milk release from breasts
