What are the structures within the muscle fiber that shorten to cause skeletal muscle fiber contraction?
Myofibrils
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. The heart has it's own built in conduction system that cause's the automatic contraction and relaxation that is required for circulation. Smooth and Skeletal muscle whether it uses voluntary or involuntary muscle contraction all have innervation to cause the contraction. Sara, RN
Where are neurotransmitters that cause skeletal muscle contraction are stored?
In the myoneural junction.
What conditions cause contractions of arteriole smooth muscle?
Asthma causes contraction of the bronchial smooth muscle.
Where are neurotransmitters that cause skeletal muscle contraction normally stored?
In the myoneural junction.
Hypocalcemia will cause the heart rate to?
slow down or will cause bradycardia. calcium is essential in muscle contraction.
What is the minimal level of stimulus to cause a muscle contraction?
it is known as the threshold stimulus usually seen in tonic contraction
Which internal structures of animals are specifically adapted to use contraction to cause movement?
Muscle
Walking is an example of which type of contraction?
Walking is an example of isotonic type of contraction. These are contractions which will force the length of the muscle to change and cause movement.
