Axon

The video explains how nerve cells transmit impulses from the body to the synapse. It highlights that the longest axons in the human body can exceed a meter, connecting the big toe to the spinal cord, making these neurons the largest cells in the body.

What is the primary function of a nerve cell in terms of impulse transmission?

• To store impulses

• To absorb impulses

• To transmit impulses away from the body

• To block impulses

How long can the longest axons in the human body be?

• Half a meter

• Over a meter

• A few centimeters

• Several inches

Which part of the body is connected to the spinal cord by the longest axons?

• The thumb

• The knee

• The big toe

• The ear

What makes neurons the largest cells in the body?

• Their speed of transmission

• Their number of synapses

• Their long axons

• Their ability to transmit impulses

What is the significance of the connection between the big toe and the spinal cord?

• It shows the complexity of the nervous system

• It highlights the size of neurons

• It indicates the number of neurons in the body

• It demonstrates the speed of impulse transmission
