Why are calcium ions necessary for skeletal muscle contractions?
calcium increases the action potential transmitted along the scarcolemma
What is the sequence of electrical changes that occurs along the sacrolemma when a muscle fiber is stimulated?
action potential
What transmission of the depolarization wave along the neurons membrane?
Action potential
What causes an action potential when it binds the motor end plate?
Chemically gated sodium channels open up when neurotransmitters bind to receptors in the motor end plate. This causes an action potential along a muscle membrane or nerve cell.
How does an action potential pass along a nerve?
no spek eengish
Why is action potential self regenerating?
By self regenerating, they mean that when you start an action potential, it continues in proximal (nearby) tissue (e.g., nerve). The depolarization of the action potential continues along the nerve.
Why is action potential self-regenerating?
By self regenerating, they mean that when you start an action potential, it continues in proximal (nearby) tissue (e.g., nerve). The depolarization of the action potential continues along the nerve.
What is the neurotransmitter of the motor neuron?
Alpha-Motor neurons release the neurotransmitter acetylcholine at a synapse called the neuromuscular junction. When the acetylcholine binds to acetylcholine receptors on the muscle fiber, an action potential is propagated along the muscle fiber in both directions.
What is the electrical message that travels along a neuron?
electrical signal
What is the neurotransmitter of alpha-motor neuron?
Alpha-Motor neurons release the neurotransmitter acetylcholine at a synapse called the neuromuscular junction. When the acetylcholine binds to acetylcholine receptors on the muscle fiber, an action potential is propagated along the muscle fiber in both directions.
When the myosin head flexes into a bend pulling the actin filament along with it this is called the A. actin reaction B. power stroke C. recovery stroke D. muscle tone E. action potential?
a
After ACh attaches to its receptors at the neuromuscular junction the next step is?
the depolarization of the muscle cell. This occurs when the ACh receptors open, allowing sodium ions to enter the muscle cell, which leads to the generation of an action potential. The action potential then propagates along the muscle cell, initiating contraction.
