3 Questions
Which component of an alpha motor neuron activates a skeletal muscle cell?
Distal component
What triggers the voltage-gated Ca+ channels to open in the terminal axon of an alpha motor neuron?
An action potential reaching the terminal axon
What is the role of AcH in the activation of a skeletal muscle cell by an alpha motor neuron?
It binds with ligand-gated Na+ channels on the postsynaptic membrane
Test your knowledge on the process of skeletal muscle cell activation in response to the distal component of an alpha motor neuron. Explore the journey of an action potential along an axon, the role of voltage-gated calcium channels, and the concentration of calcium ions inside and outside the cell. This quiz is perfect for students of anatomy, physiology, and neuroscience who want to deepen their understanding of muscle cell activation.
