1
What is neurons?
Building blocks of the neuron systems
2
Image occlusion: name the hidden labels
3
Why neurons and muscles called as excitable tissues?
Can be stimulated to create a small electrical current.
4
At rest, inside of the neuron is
- More negative
- More positive
5
Cell membrane acts as
Barrier
6
How does cell membrane creates a difference in charge?
By controlling the movement of ions in and out of the cell.
7
At rest, inside of the neuron is negatively charged due to
Unequal distribution of ions ( charged particles)
8
What is the name of the pump that involves in this?
Sodium-potassium pump
9
What is the function of sodium potassium pump?
To maintain the difference of inside and out
10
It is necessary to maintain the difference of inside and out to
Create resting potential.
11
What does sodium-potassium pump does?
- Moves 3 sodium ions into and 2 potassium ions out
- Moves 3 sodium ions out and 2 potassium ions into
- Moves 2 sodium ions out and 3 potassium ions into
- Moves 2 sodium ions into and 3 potassium ions out
