333333ABPIHormones - the chemical messengers

Notes for teachers

There are fi ve chapters that describe the endocrine system and disorders relevant to the science curriculum.

Glands, hormones and your body shows the positions of the main endocrine glands of the body and describes the hormones that they produce.

What do hormones do? illustrates the roles of hormones by briefl y describing the actions of adrenaline, growth hormone and the sex hormones.

Body in balance describes the role of insulin and anti-diuretic hormone in homeostasis.

Treating diabetes looks at how insulin can be used to treat diabetes and its production by genetic engineering.

Hormone Replacement Therapy explains the reduction in oestrogen production following the menopause and how the symptoms it causes can be treated with HRT.

ABPIHormones - the chemical messengers

Notes for teachers

1 - Endocrine glands

Page 1 introduces students to hormones and describes them as chemicals released by endocine glands, involved in the regulation of body functions. Following this introduction, students should look at picture 2 on page 2. This gives information on the position of the main endocrine glands and the hormones that they produce.

Hormones and glandsStudents should use picture 2 to complete Student worksheet 2, Hormones and glands.

Using the resource

2 - Hormones and targets

Stress that the endocrine glands release their hormones into the bloodstream. This means that the hormones travel throughout the body. However, they only have an effect on target tissues that contain the appropriate receptor.

Hormone and receptor snapThe activity Hormones and receptor snap is a simple card game that illustrates the idea that hormones are a particular shape and these will attach to receptors on their target cells. This then causes the target cells to respond in a particular manner.

The Hormones and receptor snap worksheet has a set of cards which cover relevant hormones and their target tissues. These should be photocopied (enlarged if required) and cut into individual cards. Produce sets of cards for each pair of students that contain multiple copies of each sheet.

Shuffl e the cards, deal and play as for traditional ‘snap’, however students need to pair complimentary shapes of hormones and target cells receptors.

Use the information on page 2 of the resource to complete the labels on the diagram.
