The channels themselves are called "ion channels".
There are two ways an object can pass through the membrane through ion channels:
-active transport
-passive transport
The cell membrane is hydrophilic outside and hydrophobic from inside thanks to the phospholipid. The membrane also contains protein gated channels which allow some molecules to pass through and ion channels. The transport in an out of cells is also controlled by osmotic pressure, the electric charge etc.
Membrane Membrane
Voltage-gated channels are proteins in the cell membrane which open when stimulated by a voltage (an electrical signal). The voltage causes the channel to open, thereby allowing the entry or exit of whatever substance the channel relates to. An example of this the the voltage-gated sodium channels on neurons. When an action potential (a voltage), passes over the cell, it open these channels and allows sodium to enter the cell.
the cell membrane. It is a protein mosaic this is hydrophobic on both sides and hydrophllic in the center.
The membrane surrounding the nucleus is simply called the nuclear membrane. It is a phospholipid bilayer. The nuclear membrane merges with the endoplasmic reticulum, and you can learn more by using the link below.
In the nervous system the system of membrane channels is called the neuroreceptors. Neurotransmitters use the neuroreceptors as binding sites.

Protein channels
aquaporin i think
its the cell membrane - not to be confused with the cell wall
Depends on what the pore does. If they are channels - they are called Channels. Voltage gated / ligand activated channels. If they are to communicate with neighbouring cells - they are called gap junctions.
Cisternae
rough endoplasmic reticulum
In the membrane of a cell, channels serve as passageways.
Tympantic membrane
yes they are
The "cell membrane" is the cell that is embedded with channels.
