The action potential is conducted into a skeletal muscle fiber by?
neuromuscular junctions Action potentials conduct down T tubules into skeletal muscles
Which muscle type is voluntary in action?
The skeletal muscle is the only type of muscle which is voluntary.
Why does tetrodotoxin effect your muscles?
It blocks the sodium channels that are required to create action potential in the muscles to make them contract.
In some reflex action skeletal muscles contract without the involvement of the?
i think its the brain...
What is the duration of action potential of skeletal muscle?
Action potential duration in skeletal muscle is around 2 - 5 milliseconds.
What types of action are controlled by skeletal muscles?
moving your arms,legs,fingers,etc.
How Do Muscles Act As A Skeletal Pump?
the muscles near the veins help by their muscular contractions, they press on the vein and have a squeezing pumping action.
What interferes with the action that causes the heart muscles to contract?
beta blockers
Why are calcium ions necessary for skeletal muscle contractions?
calcium increases the action potential transmitted along the scarcolemma
What is the heart muscle cells special feature?
The muscle has unique features that are only in the heart.These muscles are involuntary striated muscle which are only found in the wall of the heart. This is specialised muscle that can contract, Cardiac muscle, like other muscles, can contract, but it can also carry an action potential (i.e. conduct electricity), like the neurons that constitute nerves.Furthermore, some of the cells have the ability to generate an action potential, known as cardiac muscle automaticity.Read more: Why_is_the_cardiac_muscle_unusual
Position of muscles?
There are approximately 642 skeletal muscles within the typical human, and almost refers to the action of each muscle from the standard anatomical position.
Where is the only place you can find cardiac muscles?
Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart. This is a specialized muscle that, while similar in some fundamental ways to smooth muscle and skeletal muscle, has a unique structure and with an ability not possessed by muscle tissue elsewhere in the body. Cardiac muscle, like other muscles, can contract, but it can also carry an action potential (i.e. conduct electricity), like the neurons that constitute nerves.Furthermore, some of the cells have the ability to generate an action potential, known as cardiac muscle automaticity (meaning the can and do beat on their own).
