• Describe the structure of the human tongue (taste buds, papillae, taste cells)
• Describe how taste buds detect taste
• Name the four basic tastes 
• Describe how olfactory cells detect odours
• Describe why the sense of smell is closely linked to the sense of smell (hint: can you taste food when you have a cold)

Chapter 13: The Endocrine System (p.436-459)

• Explain what are tropic hormones (p.441)

The Pituitary Gland

• Describe the structure and function of the pituitary gland (posterior/anterior pituitary). 
• Describe who releases hGH (Human Growth Hormone) and list effects of hGH on the body
• Describe what is gigantism, dwarfism and acromegaly (p.445-446)

The Thyroid Gland

• Explain where the thyroid gland is located in the body and name the hormone (thyroxine) that is released
• Describe function of thyroid gland
• Explain what is hypothyroidism and cretinism, list some symptoms of hypothyroidism
• Explain what is hyperthyroidism, Grave's disease, goitre (p.448-449)
• Describe how thyroxine is released (negative feedback loop)

The Adrenal Gland (p.451-454)

• Explain where are the adrenal glands located and what is their function
• Describe the function of the adrenal medulla (What hormones are released? What do they regulate?)
• Describe the function of the adrenal cortex (What hormones are released? What do they regulate?)
• Describe the function of  cortisol and aldosterone

Hormonal Regulation of Blood Sugar (p.456-459)

• Describe structure and function of pancreas (islet of Langerhans, beta cells, alpha cells)
• Describe the role of insulin and glucagon
• Explain what is diabetes mellitus 
• List short and long term effects of hyperglycemia (=high blood sugar)
• Name and compare the two types of diabetes mellitus (type 1 and 2)
