Across
  1. 2. protein hormone released by the pituitary gland in the brain that increases reabsorption of water by the kidneys leading to a reduced volume of urine
  2. 4. the process by which materials enter cells through the membrane and are enclosed by vesicles within the cell
  3. 5. the way that an organism reacts to a particular stimulus
  4. 8. a specialised nerve cell that is capable of detecting a stimulus
  5. 12. a hormone secreted from the adrenal glands; it causes an increase in heart rate and blood glucose levels providing energy for muscle contraction
  6. 14. a condition where there is too much glucose in the blood
  7. 16. limits within which the body is able to function normally for such factors as temperature, pH, blood sugar
  8. 17. some change in the environment of an organism which is able to be detected by specialised cells called receptors
  9. 18. a muscle or a gland which is activated by nerve impulses via a motor neuron, thereby producing a response
  10. 19. the part of a neuron that receives impulses, across a synapse(s) from other neurons, often branches into dendrites
  11. 20. an endocrine gland located in the neck which produces the hormone thyroxine which stimulates metabolic processes
  12. 21. a series of biochemical reactions in which glucose is broken down to produce pyruvate and release energy to synthesise ATP
  13. 22. a chemical, released from an endocrine gland and carried in the blood.
  14. 26. a hormone produced by the pituitary gland that stimulates the thyroid gland to secrete the hormone thyroxine
  15. 27. a hormone which is secreted by the pancreas and increases the level of glucose in the blood, it works in the opposite way to insulin
Down
  1. 1. a receptor in the hypothalamus of the brain, capable of detecting small changes in temperature
  2. 3. multiple tiny extensions from the cell body of a neuron; they usually receive nerve impulses across a synapse from other neurons
  3. 6. feedback the effect of a response on the original stimulus, the response enhances the stimulus
  4. 7. a ‘steady-state’ condition in blood and tissue fluids which exists within the bodies of organisms, to maintain conditions which are more stable than external conditions e.g. temperature
  5. 9. a gland in the body which produces a particular hormone and secretes it directly into blood vessels for transport around the body
  6. 10. the process by which materials are enclosed by vesicles inside the cell and then expelled through the membrane out of the cell
  7. 11. lipid-based hormones, usually insoluble in water
  8. 13. the effect of a response on the original stimulus, the response reduces the stimulus
  9. 15. a model to explain how a stimulus is detected by specific receptors that transmit information to effectors which enable a response
  10. 22. a condition where body temperature rises too far above the ‘set-point’; this can be life threatening
  11. 23. a hormone which is produced by the thyroid gland and stimulates metabolic processes
  12. 24. a disease resulting from the poor regulation of blood glucose, usually associated with low levels of insulin production
  13. 25. a polysaccharide storage product found in animals, particularly in the liver and muscles, which is formed when many glucose molecules are joined together
