How the muscle of the heart different from other muscle of the heart?
The heart muscle is different from smooth and skeletal muscles because it does not require a nerve to cause it to contract.

Smooth and Skeletal muscle whether it uses voluntary or involuntary muscle contraction all have innervation to cause the contraction. Sara, RN
What conditions cause contractions of arteriole smooth muscle?
Asthma causes contraction of the bronchial smooth muscle.
Where are neurotransmitters that cause skeletal muscle contraction are stored?
In the myoneural junction.
How does the threshold stimulus influence muscle contraction?
The threshold stimulus is the stimulus required to create an action potential. So any stimulus under this level will not cause muscle contraction, while a stimulus above this level will cause the muscle to contract. The higher the stimulus the more muscle fibers are recruited, and thus the higher the response.
Which type of contraction is most likely to cause discomfort in q5?
