Across
- 2. The part of a neuron that integrates all the incoming IPSPs and EPSPs to determine if an action potential will fire
- 6. One muscle cell is also called a ___________ __________, and is made up of many myofibrils.
- 8. This is where the electrical signal that makes the heart pump originates
- 9. the part of a neuron the propagates an electric signal to the next neuron
- 11. After an action potential is fired, Na/K pumps and K leak channels must bring the charge of the cell back to resting potential because it went through _________________
- 14. These structures in the heart prevent backflow of blood
- 15. The type of cell that sends an electric signal to effector organs/muscles
- 16. These ions must enter the end of an axon in order to tell vesicles holding neurotransmitters to fuse with the cell membrane
Down
- 1. Action potential is said to "jump" down an axon because of the layers of _____________ ____________
- 3. A graph that responds to the electrical signals of the heart
- 4. As an action potential reaches the end of the pre-synaptic neuron, electrical signal turns into _____________ signal
- 5. This is the force exerted on the walls of arteries, capillaries and veins
- 7. The rapid, potential change in a cell's membrane potential
- 10. ions flow through ____________ gated channels
- 12. The type of cell that transmits electric signals from a sensor to a motor neuron
- 13. this type of signal will lower the membrane potential of a cell
