Across
  1. 5. sheath insulation covering the axon
  2. 6. Clumping of particles. An antigen is mixed with the antibody (usually used in blood grouping)
  3. 13. Tumor or growth wich isnt cancerous. Grows slowly and isn't harmfull.
  4. 15. nervous system brain and spinal cord.
  5. 16. Towards the head
  6. 19. Help blood clot and slow bleeding.
  7. 20. flexation movement away from the body of the foot
  8. 21. summation effect of triggering an action potential in a neron from one or more presynaptic neurons
  9. 23. At a higher level than ….
  10. 29. At a lower level than …..
  11. 30. (equilibrium) potential depends on the concentration gradient for that ion across the membrane
  12. 32. bottom part of spine (5 fused vertebrate)
  13. 33. Consiting of all bones and joints
  14. 35. Excessive accumulation of fluid in the body tissue (inflammation)
  15. 38. Refers to the back of the body
  16. 41. nervous system vouluntary control and bodily movements.
  17. 43. Top part of the spine (7 vertebrate)
  18. 46. portion Consisting of the head, neck and the trunk
  19. 48. synapses biological junctions which signals can be sent to each other
  20. 50. bacteria transport compounds outside the cell which are potentaialy toxic.
  21. 52. Middle part of the spine (12 vertebrate)
  22. 54. indirectly linked with ion channels through signal transduction mechanisms shuch as G proteins
  23. 59. a nerve synapse between an axon and a dendrite
  24. 60. synapses mechanical and elctrically conductive link between to synapses
  25. 61. Far away from the trunk
  26. 62. plane Divides the body into right and left
  27. 64. Constiing of all the nerves, both the central nervous system and the pripheral nervous system
  28. 65. postsynaptic potential (IPSP) synaptic potential that makes a postsynaptic neurone less likelt to generate an action potental
  29. 66. Consiting of skin, sweat glands, hair, nails
Down
  1. 1. cell pyramid shaped cell with a single axon and many dendrites
  2. 2. Cancerous cells that have the ability to spread, uncomntrolled growth.
  3. 3. connects to brain cell and spinal cord
  4. 4. nervous system contains all the nerves that lie ouside the CNS.
  5. 7. postsynaptic potential (EPSP) change in membrane voltage of a postsynaptic cell following the influx of positively charged ions into a cell
  6. 8. Neuron which has two extensions
  7. 9. Refers to the front of the body
  8. 10. nerve ending relay the signal to nerons
  9. 11. middle bottom part of spine (5 vertebrate)
