As а grаduаte teaching assistant fоr yоur physiоlogy class, you are required to provide a grade of the following examples of student work regarding receptors. No two answers can have the same grade assigned. 1. Net postsynaptic neuronal influence determines whether or not a presynpatic neuron reaches threshold and generates an action potential. Membrane potential movement towards greater negatives are excitatory. For example, stimuli resulting in negative ion efflux or positive ions influx moves membrane potential away from threshold and can be referred to as temporal summation. [q1] 2. Postynaptic membranes receive both excitatory impulses (which increase the likelihood of threshold), and inhibitory impulses (which decrease the likelihood of threshold). Excitatory temporal summation results from multiple action potentials in a presynaptic neuron causing sustained neurotransmitter release that results in ligand-gated Na+ channels opening in the postsynaptic membrane. [q2] 3.Synaptic integration refers to the fact that a multitude of graded synaptic impulses are necessary to eventually summate and produce action potentials. The combination of excitatory (temporal) and inhibitory (spatial) influences acting at any time will influence the likelihood of the axon hillock reaching threshold, voltage-gated Na+ channels being opened and action potential generation. [q3]
