What do the semicircular canals sense Correct Answer-Angular velocity Blank is the component of the motor neuron where the excitatory post-synaptic potentials summate to generate an action potential? Correct Answer-Axon Hillock What neurons are cutaneous mechanoreceptors innervated by? Correct Answer-A: Ab What would be the benefit of low threshold (type 1) motor neurons or small motor neurons innervating slow oxidative muscle fibers/ large motor neurons and high threshold (type II) mot...

BIO 181 (Capco ASU) Exam 3 (Final Exam) Questions with Verified Solutions Briefly explain why the action potential flows only from the axon hillock to the terminal web. The action potential originates from the axon hillock which initiates the flow of the action potential because of the presence of higher density voltage-gated ion channels. Draw a neuron, and label all the parts as described in lecture. Draw an action potential in the axon of a neuron and indicate which ions flow int...
