Question

The ____________ segment includes both dendrites and the cell body, which are the regions of the neuron that receive stimuli to excite the neuron. Channels in this region are ____________ ; no significant numbers of ____________ channels are present.

• The ____________ segment is composed of the axon hillock. This segment contains voltage-gated channels.
• The ____________ segment is equivalent to the length of the axon. It contains voltage-gated channels.
• The ____________ segment includes the synaptic knob and contains voltage-gated channels and ____________ .

Answer 1

Answer: The Receptive segment includes both dendrites and the cell body, which are the regions of the neuron that receive stimuli to excite the neuron. Channels in this region are Chemically gated ; no significant numbers of Voltage-gated channels are present.

• The Initial segment is composed of the axon hillock. This segment contains voltage-gated channels.

• The Conductive segment is equivalent to the length of the axon. It contains voltage-gated channels.

• The Transmissive segment includes the synaptic knob and contains voltage-gated channels and Pumps.

Answer 2

The (Receptive) segment includes both dendrites and the cell body, which are the regions of the neuron that receive stimuli to excite the neuron. Channels in this region are (Gated chemically) ; no significant numbers of (Voltage gated) channels are present.

• The (Initial) segment is composed of the axon hillock. This segment contains voltage-gated channels.

• The (Conductive) segment is equivalent to the length of the axon. It contains voltage-gated channels.

• The (Transmission) segment includes the synaptic knob and contains voltage-gated channels and (Pumps) .
