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.
What is the minimal impulse that can initiate a muscle contraction?
Threshold stimulusThe minimal level of stimulation required to cause a fiber to contract is called the THRESHOLD STILULUS.
Does Muscle glycogen cause muscle contraction?
no, lactic acid does
The minimum stimulus needed to cause a contraction is called the?
threshold stimulus
What does noradrenaline do?
It can cause vascular smooth muscle contraction
Which type of contraction is most likely to cause discomfort in q5?
The eccentric muscle contraction is most likely to cause discomfort in q5.
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.
A weak stimulus can cause a muscle fiber to contract only partway?
yes
What conditions cause contractions of arteriole smooth muscle?
Asthma causes contraction of the bronchial smooth muscle.
Do Every muscle fiber has several motor end plates that neurons attach to yes or no?
Muscle fibres are connected to neurones on either a 1:1 ratio (such as fingers, where precise muscle control is needed) whereas some muscle fibres are connected to neurones in a 1 neurone:several muscle fibres ratio. The second occurs where precise movement is not needed, such as the calf muscle, where a stimulus needs to cause a large and synchronised contraction of muscles as opposed to precise contraction of certain individual fibres.
