What part of a neuron would probably be affected most by the application of Novocain?
Novocain blocks calcium channels. Voltage-dependent calcium channels are a group of ion channels found in the membrane of excitable cells such as the axons of neurons and glial cells.
Which transport is used to move calcium in or out of the cell?
Calcium is primarily transported into or out of the cell using specialized protein channels called calcium channels. These channels allow calcium ions to move across the cell membrane, either into the cell (via calcium influx) or out of the cell (via calcium efflux). Additionally, calcium can also be transported into the cell by calcium transporters such as ATPase pumps.
What causes the rapid change in the resting membranes potential that initiates an action potential?
In muscle cells the inward current is a sodium + calcium flow through acetycholine activated channels as well as through voltage sensitive calcium channels.
What type of channel is responsible for action potential?
Remove this? Has been answered in similar question. Calcium, Potassium, Sodium.
What is the fast rising phase of the SA node action potential is due to?
opening of slow calcium channels
What would happen if a chemically gated sodium channel in the postsynaptic membrane were completely blocked?
The nervous system would not work if ion channels were blocked. It would be like parking your car on a hose and trying to get water out of the hose.
A calcium ion channel will allow?
Only calcium ion channels to pass through it.

What part of a neuron contains calcium pumps and channels?
AXON

When an action potential arrives at the axon terminal of motor neuron which ion channels open?
voltage-gated calcium channels
In a neuron where are voltage-gated calcium channels located?
Found in the terminal
Why has PEMRA ban Indian channels Pakistan?
because indian counterpart has blocked pakistani channels and it's reaction. also there is no dth service, which could deliever a huge number of channels besides her own.
What would happen if you ate pure calcium?
Nothing would happen. You would just get a lot of calcium.
What causes the rapid change in the resting membranes potential that initiates an action potential?
In muscle cells the inward current is a sodium + calcium flow through acetycholine activated channels as well as through voltage sensitive calcium channels.
When did Battle of the Dalmatian channels happen?
Battle of the Dalmatian channels happened on 1991-11-16.
Are all the gated calcium channels concentrated at the nodes of ranvier of myelinated axons?
no, most gated mandiable channels are concentrated at the nodes of ranvier of myelinated axons.
