Some cells with very negative resting membrane potentials, like -80 mV, express an the inward rectifier K+ channel. Describe the channel/ conductance.

If a resting potential becomes more negative, the membrane is said to be __________.

Axosomatic synapses

Difference between impulse conduction in a myelinated nerve fibre and unmyelinated nerve fibre.

True or false. The different subunits that a muscatinic acetylcholine receptor is made of determines the properties of the receptor such as what ion it conducts. If false what is determines the properties ?
