Excitable cells can propagate:
|
action potential
|
|
|
Inside of a cell is (-)/(+) which makes a cell a (-)/(+) resting potential
|
(-) (-)

|
3 Types of Transport Proteins and Gradient:
|
Carrier, Channel, Pump
Down, Up, Downhill |
|
|
K Channels: Type:
In/out: Na Channel: Type: In/out: Ca Channel: Type: In/out: |
K Channels: Type: voltage
In/out: out Na Channel: Type: voltage/ligand In/out: In Ca Channel: Type: many In/out: IN Cl Channel: Type: many In/out: IN |
|
|
4 Types of Channel gates:
|
Voltage
Ligand Mechano Ungated |

|
4 Steps to action potential
|
1. Resting (k+ and Na+ closed)
2. Depolarization (Na+ IN) 3. Repolarization (K+ Out) 4) Hyperpolarization (K+ out) |
|
|
Steps to neurotransmitter release (8):
|
Action Potential
Depolarization = open calcium channel Neurosecretory vescicles secreted Reserved vesicles are released readied for secretion Neurotransmitter diffuses Binding Channel opens causing depolarization Transmission of Action potential |
|
|
Excitory synapses causes
Inhibitory cause |
depolarization
polarazation |
