Are your TARGET's CORRECT?

1. Receptor

2. Target Cells

3. Anterior pituitary gland

4. Thyroid gland

5. Reproductive organs

6. Bone, kidney, GI tract

7. Reproductive organs

8. Adrenal cortex

9-10. Steroid hormone receptors and Peptide hormone receptors

Case Analysis:

Target cell responds to the hormone to perform the hormones mechanism, it triggers the hormones action. Hormone receptors are found either the surface or inside of the cell. Binding of hormone to the receptor initiates the reaction.

Did You Find your TARGET?

1. It triggers the action of hormone in a target cell.

2. They are the receptors of the hormones.

3. The target cell of the TRH.

4. The target cell of TSH.

5. The target cell of LH.

6. The target cell of Calcitonin.

7. The target cell of FSH.

8. The target cell of Antidiuretic hormone.

9-10. two types of cell receptors.


Case Analysis:

Discuss the mechanism of action of the target cell.

TARGET CELLS

Target cells are the receptors of the hormone. Hormones have a specific target cell. It responds to the hormone because it has receptors for the hormone. Hormone receptors are found either the surface or inside of the cell.

Binding of hormone to the receptor initiates the reaction. The TRH target cell is located in the cytoplasm intra-cellularly. In order to bind to the specific receptor the hormone has to travel to the membrane of the cell and bind to the DNA.
