Which statement is incorrect regarding synapses and nerve impulses? A. A synapse is the space between two neurons. B. A nerve impulse of the presynaptic neuron causes the release of a neurotransmitter into the synaptic cleft. C. The neurotransmitter diffuses across the synaptic cleft and binds to the receptors on the postsynaptic membrane. D. Activation of receptors stimulate saltatory conduction.
D. Activation of receptors stimulate saltatory conduction.

Frontal
Parts of the Cerebrum
Frontal Lobe Parietal Lobe Occipital Lobe Temporal Lobe
Clusters of cell bodies located outside the central nervous system
Ganglia
The outer meningeal layer, the dura mater, is durable. It is therefore best described as
