Document Content and Description Below
Neuron Function How does a signal travel across and between neurons? Why? Just as the coaxial cables that run down your street or through your house carry television and Internet signals, the job ... of a neuron is to move an electrical signal from one place to another in order to send sensory messages throughout the body. In a previous activity you saw how a membrane potential is formed both at rest and during an inflow of ions. In this activity you will explore how changes in membrane potentials can propagate a signal down the axon of a neuron. 1. Which of the gated embedded proteins in Model 1 allow sodium ions ( ) through the membrane? 2. Which of the gated embedded proteins in Model 1 allow potassium ions ( ) through the membrane? 3. The neuron illustrated in Model 1 has received a signal from either a sensory cell (taste bud, skin cell, retinal cell, etc.) or from another neuron. What evidence do you find in diagram 1 of the model that indicates a signal has been received? CONTINUED... [Show More]
