5.1 Identify the type of neuron represented in the diagram. (1) 5.2 State ONE function of part B. (1) (2) . Study the section on human endocrine system and homeostasis in humans in the Mind the GAP Study Guide on p.53 61 before you answer the following questions. In question one – the answers are provided with an explanation (DBE, June 2016, Paper 1) Q1 The diagram below represents parts of the endocrine system in humans. 1.1 Identify gland: (a) A (1) (Hypophysis/ Pituitary gland study the diagram on p.53 of the Mind the Gap study – guide) (b) B (1) (Adrenal gland gland on top of the kidney) – 1.2 Give the LETTER and the NAME of the gland that secretes a hormone responsible for: (a) Starting puberty in males (2) (D Testis - produces testosterone which is responsible for the development of the – secondary sexual male characteristics) (b) Stimulating absorption of glucose by cells (2) (C Pancreas/Islets of Langerhans produces insulin which stimulates cells to – – absorb glucose) (c) Making the kidney tubules permeable to water (2) (A Hypophysis/Pituitary gland produces ADH which increases the permeability of – – the renal tubules so that more water can be re-absorbed into the bloodstream) (8)
