What are the two types of receptors?

Inotrophic receptors

Metabotropic receptors

Endrotropic recptors

Nitrophic receptors

Which receptor is characterised by its involvement with the opening or closing of ion channels?

Inotrophic

Metabotrophic

Which recpetors are slower, longer lasting and more diffuse and varied?

Inotrophic

Metabotropic

With Inotrophic reactors If the Na+ channnels are opened an (x) post synaptic potential occurs.

Exitatory

Inhibitory

With Introphic reactors if the K+ (sodium)channels are opened an (x) post synpatic potential occurs.

Exitatory

Inhibitory

What can happen when neurotransmitters are released? (numerous answers)

They get taken up by the presynaptic recpetors

They get destroyed in the gap, before they get to the post synaptic receptors

They get taken up by post synaptic recpetors
