Involuntary muscle includes _________.
hodyreva [135]

Answer:

smooth muscle and cardiac muscle only.

Explanation:

because all of these muscles are involuntary meaning all of these muscles are not moveable by choice, you can not decide when to move these muscles. Foe example we can not control the heart muscles, the heart needs to pump involuntary, but the other muscles from the list we have control over. For example we can make a choice when it comes to moving some skeletal muscles, but not a choice when moving smooth muscle and cardiac muscle .

What is the correct sequence of events along an axon that follows a membrane reaching threshold potential?
Oksi-84 [34.3K]

As sodium ions diffuse inward, sodium channels open.

Membrane depolarization occurs.

Potassium ions spread outward as potassium channels open.

Membrane repolarization occurs.

<h3>What happens along an axon in the right order ?</h3><h3 />

An action potential, which is a fast change in membrane potential, develops when the membrane potential of a neuron's axon hillock hits threshold. There are three steps to this shifting change in membrane potential. Depolarization occurs first, then repolarization, and then there is a brief phase of hyperpolarization.

  • A depolarizing current causes an explosion of electrical activity known as the action potential. This indicates that the resting potential shifts toward 0 mV as a result of some action (a stimulus).
