T or F: Potassium ions are at high concentrations inside of cells, including neurons.
True
The action potential is the result of:
the movement of ions
The postsynaptic cell can be:
in glands, muscle cells, and neurons
Th resting potential of a neuron is
-60mV
T or F: The cell body refers to the part of the neurons that begin at the dendrites and extend to the axon
terminal.
false
T or F: Voltage gated ion channels open with the binding of a protein to the receptor.
False
, T or F: Excitatory synapses hyperpolarize postsynaptic cells
false
T or F: Acetylcholinesterase splits acetylcholine to muscarinic acid
false
With regard to the motor end plate the immediate event which triggers exocytosis is
calcium ions
T or F: Fast Neurons as described in lecture require cytoplasmic signal transduction to open an ion
channel.
False
T or F: Myelin coats only pre-synaptic neurons.
False
T or F When the presynaptic cell connects to a muscle cell the synapse area is called a motor end plate.
True
