What else can I help you with?
Which term does not belong excitability response to a stimulus contractility action potential?
The term that does not belong is "action potential." While excitability, response to a stimulus, and contractility are all related to muscle function and the ability of muscle fibers to react to stimuli, an action potential refers specifically to the electrical impulse that triggers these processes.
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.
What is the graded potential generated along the muscle cell membrane?
The graded potential generated along the muscle cell membrane is known as an action potential. This is an electrical signal that travels along the membrane of the muscle cell, leading to muscle contraction. It is initiated by the movement of ions across the membrane in response to a stimulus.
When the what reaches the end of the axon the neurotransmitter is released?
When the _____________reaches the ends of the axon the neurotransmitter is released and it diffuses to the muscle cell membrane to combine with receptors there?Sarcolemma
When an action potential is initiated on a nerve cell membrane it radiates and is propagated in all directions from the point of initial stimulation?
Correct. The action potential is initiated at a specific point on the cell membrane called the axon hillock, and it then travels down the axon in one direction. Once initiated, it spreads along the entire length of the axon and can be transmitted to other neurons or muscle cells.
The ability of a muscle to transmit electrical current is termed?
The ability of a muscle to transmit electrical current is termed conductivity. This refers to how well the muscle tissue can carry an electrical impulse, allowing for proper communication between nerves and muscle fibers to produce movement.
What is the name for the impulse generated when a neuron fires?
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineAcetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction
What ions are important in muscle contraction and impulse conduction as an action potential reaches a synapse?
In muscle contraction and impulse conduction, important ions include calcium (Ca2+), sodium (Na+), and potassium (K+). Calcium plays a key role in triggering muscle contraction by binding to troponin, sodium influx starts the action potential at the synapse, while potassium efflux helps repolarize the membrane after the action potential passes.
Traveling wave of excitation is known as?
Traveling wave of excitation is known as an action potential in nerve cells or an impulse in muscle cells. This wave allows for communication and coordination of cell activities in the body.
What event occurs as a result of a muscle action potential?
Reflex action
Describe the path a nerve impulse travels throughout your body from stimulus to response?
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineAcetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction
What do muscles need so they can contract?
i know that you need a nerve impulse the second i think is calcium and i don't know what the third is. Movement is initiated by muscles (forces) moving about levers (bones, etc humerus) about axes (our joints). In order for a muscle to contract a neural impulse in needed and in the abssence of a neural impulse calcium is reabsorbed into the; sarcoplasmic reticulum ( part of a single muscle fibre)
