The ions that enter the muscle cell during action potential generation are?
cacium ions
What is the period of time that elapses between the generation of an action potential and the start of muscle tension development in a muscle fiber?
latent period
What is the duration of action potential of skeletal muscle?
Action potential duration in skeletal muscle is around 2 - 5 milliseconds.
What event occurs as a result of a muscle action potential?
Reflex action
An electrical impulse moving down an axon is called?
This is called action potential. Action potential is the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.
Triggering of the muscle action potential occurs after?
Triggering of the muscle action potential occurs after acetylcholine binds to chemically-gated channels in the end plate membrane.
Why is the cardiac action potential longer?
The reason why cardiac muscle has a longer action potential is to extend the absolute refractory period to prevent another action potential. If too many action potentials stimulate the cardiac muscle it can get into tetanus which keeps the heart continuously contracted without relaxation.
The ability of a muscle to transmit electrical current is termed?
action potential
What is the term for the rapid rise and fall in force produced by a muscle fiber after a single action potential?
A twitch is the rapid rise and fall in force produced by a muscle fiber after a single action potential.
What effect does adrenaline have on gut smooth muscle?
It makes the muscle totally relax as it blocks the action potential in the nerves.
In a muscle group the muscle that relaxes during a particular action is what?
gdg
Why is muscle excitable tissue?
Muscle is excitable because it can be stimulated in order to cause contraction. Stimulation comes from the nervous system via electric signals/action potential that travels from neuron through axon to muscle tissue.In-depth Details:Neuron sends action potential down its axonOnce reaching the muscle tissue, the action potential stimulates release of Ach (acetylcholine)Ach crosses the synapse and binds to a muscle fiber (cell of muscle tissue),This stimulates action potential on the sacrolemma (plasma membrane of muscle cell)Action potential travels on the sacrolemma until it reaches a T-tubuleAction goes down the T-tubule and into the muscle fiberThis stimulates release of Ca2+ (calcium) from the sarcolemmaCa2+ binds with troponinWhich stimulates tropomyosin to move out of the way so that actin and myosin can interactIf ATP is available from mitochondria in muscle fiber, cross-bridge cycle occursContraction of muscle stops when the muscle is no longer stimulated from the nervous system
