Physiology I: Introduction to Neurones, Excitatory and Inhibitory Neurotransmission in the CNS

In terms of a neuron, the soma refers to which part?

Match the neuron type to its appearance.

What is the resting potential in a neuron?

The upstroke of the neuron action potential is mediated by voltage gated [blank_start]Sodium[blank_end] channels The downstroke is then mediated by voltage gated [blank_start]Potassium[blank_end] channels

Saltatory conduction describes the way in which action potential jump from one [blank_start]Node of Ranvier[blank_end] to the next

The release of the neurotransmitter in a synapse at the end of a neuron is mediated by which type of channel?

The part of the synapse that stores the neurotransmitter is called the [blank_start]vesicle[blank_end]

Types of Synapse: [blank_start]Axodendritic[blank_end] Synapse from axon to dendrite [blank_start]Axosomatic[blank_end] Synapse from axon the cell body [blank_start]Axoaxonic[blank_end] Synapse from axon to axon

Synapses can be classified as excitatory or inhibitory. Excitatory synapses most frequently use the neurotransmitter [blank_start]glutamate[blank_end] Inhibitory synapses most frequently use the neurotransmitter [blank_start]GABA[blank_end]

As well as GABA, what is the other main inhibitory neurotransmitter? [blank_start]Glycine[blank_end]
