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.

What stimulus below this intensity will result in no response in a neuron?
Any stimulus below the neuron's threshold potential will not result in a response, as it is not strong enough to generate an action potential. Neurons require a minimum level of stimulus intensity to reach the threshold potential and fire an action potential.
The ability of the myocardial cells to respond to an electrical stimulus is known as what?
The ability of myocardial cells to respond to an electrical stimulus is known as excitability. This property allows the cardiac muscle cells to generate action potentials in response to electrical impulses, facilitating coordinated heart contractions and maintaining effective blood circulation. Excitability is a crucial aspect of the heart's electrical conduction system.
What is the ability to respond to nerve stimulus?
The ability to respond to nerve stimulus is known as excitability or irritability. This property allows nerve cells, or neurons, to react to stimuli by generating electrical impulses, which then transmit signals throughout the nervous system. This response is crucial for coordinating bodily functions, reflexes, and communication between different parts of the body. Factors such as ion concentrations and the health of the nerve cells influence this excitability.
What is a naturally occurring reaction to a particular stimulus?
The reaction to a stimulus is called a response. An intensified stimulus usually evokes a more intense response. Of course the type of response to a stimulus depends on the nature of the stimulus. Scream at someone and they likely will feel verbally attacked. The screaming is the stimulus, feeling attacked is the response.
A change in an organism's environment that causes the organism to react is called?
The change is actually a stimulus and when the organism reacts to the stimulus, it becomes a response. Overall, The answer is a stimulus.
What does not belong excitability response to stimulus contractility action potential?
Excitability! cha cha!
What stimulus below this intensity will result in no response in a neuron?
Any stimulus below the neuron's threshold potential will not result in a response, as it is not strong enough to generate an action potential. Neurons require a minimum level of stimulus intensity to reach the threshold potential and fire an action potential.
Which muscle characteristic describes the ability of muscle to respond to a stimulus?
Excitability
What is The ability of the heart muscle cells to shorten in response to an electrical stimulus is known as?
The ability of heart muscle cells to shorten in response to an electrical stimulus is known as contractility. This property allows the heart to pump blood effectively throughout the body. Contractility is influenced by various factors, including the availability of calcium ions and the overall health of the heart muscle. It is a crucial aspect of cardiac function, impacting stroke volume and cardiac output.
What does the medical term contracture mean?
Contractility is the ability of a muscle to shorten in response to a stimulus.
The ability of the myocardial cells to respond to an electrical stimulus is known as what?
The ability of myocardial cells to respond to an electrical stimulus is known as excitability. This property allows the cardiac muscle cells to generate action potentials in response to electrical impulses, facilitating coordinated heart contractions and maintaining effective blood circulation. Excitability is a crucial aspect of the heart's electrical conduction system.
What is the relationship between the absolute and relative refractory periods in the context of neuronal excitability?
The absolute refractory period is the time when a neuron cannot generate another action potential, regardless of the stimulus strength. The relative refractory period is the time when a neuron can generate another action potential, but only with a stronger stimulus. These periods help regulate neuronal excitability by ensuring that neurons fire in a controlled manner and prevent excessive firing.
What is the relationship between a stimulus and a response?
A response is always triggered by a stimulus. One example is in a neuron (nerve cell). Once a sensory stimulus is witnessed (a stimulus from one of the 5 senses), the cell hits an action potential, and the response is carried out. Simply put: A human eye is closed. Once the eye opens thousands of sensors in the eye pick up the photons bouncing off all objects (stimulus), and the human is able to see (response).
What is the difference stimulus and response?
A stimulus is an external event that triggers a response in an organism. A response is the reaction or behavior that an organism exhibits as a result of a stimulus. In short, a stimulus is the input, while a response is the output.
What is known as the period of lost excitability?
The period of lost excitability, also known as the refractory period, refers to the time following an action potential during which a neuron is unable to fire another action potential. This period is divided into two phases: the absolute refractory period, where no stimulus can trigger another action potential, and the relative refractory period, where a stronger-than-normal stimulus is required to initiate one. This phenomenon is crucial for the proper functioning of nerve impulses, ensuring that signals are transmitted in a unidirectional manner and preventing excessive firing.
What is local response?
Local responce is a small change in membrane potential caused by a subthreshold stimulus.
What is the ability of a muscle to respond to nerve stimulus called?
neuromuscular efficiency neuromuscular efficiency
