The action potential is conducted into a skeletal muscle fiber by?
neuromuscular junctions Action potentials conduct down T tubules into skeletal muscles
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.
Contraction mechanism in a skeletal muscle cell?
ACH is released at the end-plate potential. ACH diffuses into the sarcolemma, attaches to the receptors in the motor end plate and causes a change in the ions permeability that creates graded depolarization of the end-plate potential. Basically, it attaches to the receptors in the motor-end plate and creates the beginning process of triggering muscle contractions.
Does the trachea have skeletal muscle?
No, it doesn't have skeletal muscle,, only smooth muscle..
The action potential is conducted into a skeletal muscle fiber by?
neuromuscular junctions Action potentials conduct down T tubules into skeletal muscles
Why are calcium ions necessary for skeletal muscle contractions?
calcium increases the action potential transmitted along the scarcolemma
What action is exerted by the muscle on the bone?
skeletal
What ensures that one action potential in the neuron yields only one action potential in the skeletal muscle fibers of the stimulated motor unit and therefore only one contraction per fiber?
sarcoplasmic reticulum
Is muscle action be voluntary?
We have three types of muscle tissue; smooth, cardiac, and skeletal. Skeletal muscle tissue is the only one of the three that are voluntary.
What potential motor end plate to synapse to acetylcholine synaptic cleft to special receptors on the skeletal muscle to action potential across the muscle travels down t-tubule to the what?
This is the neuromuscular junction. The action potential travels down the presynaptic motor neuron, releasing acetylcholine (ACh), which cross the synapse (neuromuscular junction), to bind to receptors on the end plate of muscle fibers, which induces depolarization, causing the muscle to contract.
What site of action for skeletal muscle relaxants is the?
limbic system
Which muscle type is voluntary in action?
The skeletal muscle is the only type of muscle which is voluntary.
What must be pumped in order to move by the action of the skeletal muscle?
lymph
What do heart muscle cells look like?
The cells of heart muscle are striated (like stripes on a tie) as is skeletal muscle. Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart. They can contract but also carry an action potential (i.e. conduct electricity), like the neurons that constitute nerves. Some of the cells have the ability to generate an action potential, known as cardiac muscle automaticity. That is they beat on their own and in union with each other.
Type of muscle that is voluntary and striated?
SKELETAL (:
When one skeletal muscle contracts and it opposing mucsle relaxes it is an example of?
antagonistic muscle action.
