The Nervous System edit) 1. The junction between one neuron and the next, or between a neuron and an effector is called: A) A synapse 8) A dendrite C) A neuotransmiter D ) A ventricle E) None of the above 2. A fast excitatory synapses follows this order A) (1) neurotransmiter released (2) diftused across the synaptic cleft to a receptor protein (3) binding of the transmitter opens pores in the ion channels and positive...

Neurons rely on glial cells for Select one: a. protection. b. metabolic support. c. insulation. d. All of the above Neurons can be categorized by Select one: a. which neurotransmitters they release. b. their function (e.g., sensory versus motor). c. their location and/or morphology. d. All of the above Dendritic spines serve to Select one: a. increase the surface area of the dendrite. b. insulate the axons. c. insulate the dendrites. d. protect the dendrites from degrading enzymes in the...
The reason why action potentials are described as "all or none" is: a. because neurotransmitter is released from all axon terminals or none of them. b. an action potential arriving at an axon terminal either causes all the neurotransmitters to be released or none to be released. c. either all ion channels in the axon membrane open or none open. d. if an action potential is generated in a neuron, the amplitude does not depend on the stimulus strength. e....
