2. Of dendrite, sarcomere, cell body, axon, and trigger zone, this is NOT found in the neuron. - sarcomer

3. A chemical that crosses a synapse to stimulate a target cell - neurotransmitter

4. During this phase Na+ channels are open - 2 1 2 3 4 5

5. A light sensing cell found in the vertebrate eye is called this - photoreceptor

6. This part of the brain that expanded in mammals to allow for complex integration - cerebrum

7. Human hearts have this many chambers - 4

8. In this vessel, blood travels the slowest - capillary

9. This blood vessel returns oxygenated blood back to the heart from the lungs. – pulmonary vein

10. Comparing thickness in the walls of arteries, walls of veins are - thinner

11. In a blood pressure reading of 120/70, 120 refers to this - systolic

12. The process where substances move from an area of high concentration to an area of low concentration - diffusion

13. Thin walled air sacs in the lungs are called this - alveoli

14. This is the muscle that allows for ventilation of the lungs in mammals - diaphragm

15. Of High or Low pH, this condition creates the highest affinity for oxygen in the blood. – high

16. This type of pressure is exerted on the lungs during inhalation (inspiration) in mammals. - negative

17. Annelids use this as their osmoregulatory organ - nephridia

18. This is the part of the nephron where countercurrent exchange is used to concentrate urine. – Loop of Henle

19. True or False, Saltwater fish drink copious amounts of seawater – True

20. This is the part of the nephron where reabsorption of glucose occurs – distal tubule

21. This structure in the nephron is usually larger in desert animals – Loop of Henle

22. This structure increases surface area for absorption in the small intestine - villi

23. Of mouth, stomach, gall bladder, and small intestine, this organ does NOT secrete digestive enzymes. – gall bladder

24. This vital nutrient acts primarily as a coenzyme - vitamin

25. This hormone, released by the pancreatic islets of Langerhans, causes glucose to be taken up by cells - insulin

26. Bile is used to do this to fat. - emulsify

27. This protein makes up the thin filaments in sarcomeres - actin

28. This protein makes up the thick filaments in sarcomeres - myosin

29. The part of the muscle cell that releases calcium ions is this – Sarcoplasmic reticulum

30. This must be added to myosin to reset the contraction cycle - phosphate

31. Land Animals with hydrostatic skeletons use this type of muscular contraction primarily to move - peristalsis

32. True or False, endotherms can maintain their body temperature in hot or cold weather. - true

33. Of physiological or behavioral, Ectotherms only use this type of response to changes in environmental temperature. - behavioral

34. This is the stimulus to which the fish lateral line and the mammalian semicircular canals integrate. – balance (orientation)

35. Cnidarians use this structure to absorb gases and nutrients. – gastrovascular cavity

36. These structures probably evolved from gut out- pouchings in certain species of fish. - lung

37. Development

38. This is the first stage in vertebrate embryo development when the cells are pleuripotent – gastrula
