Depolarization
binds to specific receptors on postsynaptic cell membrane
Nuro transmitter is a substance that diffuses through the prism optic membrane and passes through the synoptic club and lastly deposited at the receptors present on the postsynaptic membrane
The cell membrane is semi-permeable.
Animal cell membranes are a semi-permeable membrane.
it is permeable to some molecules and not permeable to others.

The cell membrane is semi-permeable.
Animal cell membranes are a semi-permeable membrane.
it is permeable to some molecules and not permeable to others.
Cell membrane is elastic and transparent. It can be impermeable, permeable, semi-permeable or selectively permeable. In humans the plasma membrane is selectively permeable that is it allows entry to certain substance.
Calcium ions enter the presynaptic neuron resulting in the release of neurotransmitter from the per-synaptic membrane. The neurotransmitter diffuses across the synaptic cleft, fusing with the receptors of the post-synaptic membrane. This changes the sodium channels to open and sodium ions will to flow into the post-synaptic neuron, depolarizing the post-synaptic membrane. This initiates an action potential. After the post-synaptic neuron has been affected, the neurotransmitter is removed by a type of enzyme called cholinesterase. The inactivated neurotransmitter then returns to the pre-synaptic neuron.
permeable membrane: is a membrane that allows water to pass through the membrane ; the salt water is then left out
