Skeletal Muscle Action Potential – Part 2 Take a look again at the graph of an action potential on the sarcolemma of a skeletal muscle cell (given below). Describe what is happening at a molecular level to generate the depolarization and repolarization phases. Make sure to include in your answer: which ions are moving, in what direction each ion is moving, and what kind of channel each ion is moving through.  

Compare the values below. Which is greater, or are the two values equal? A. Contribution of voltage-gated sodium channels to muscle cell depolarization B. Contribution of voltage-gated potassium channels to muscle cell depolarization

Compare the values below. Which is greater, or are the two values equal? A. Number of neurons in the path between the CNS and the target in the sympathetic NSB. Number of neurons in the path between the CNS and the target in the parasympathetic NS

Is the statement below True or False? Generation of an end plate potential requires activation of chemically-gated cation channels.

Is the statement below True or False? Auditory information is relayed to the occipital lobe by the medial geniculate nucleus of the thalamus.

In a skeletal muscle fiber, a triad is composed of…

Skeletal Muscle Action Potential – Part 1 This image below is a graph of an action potential on the sarcolemma of a skeletal muscle cell. Match the letters (A, B, C, D, E, F, G, and H) on the image to the corresponding feature that they represent on the graph.  

Neuron Action Potential – Part 1 This image below is a graph of an action potential on the membrane of a neuron. Match the letters (A, B, C, D, E, F, G, and H) on the image to the corresponding feature that they represent on the graph.
