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.
Which muscle characteristic describes the ability of muscle to respond to a stimulus?
Excitability
What does the medical term contracture mean?
Contractility is the ability of a muscle to shorten in response to a stimulus.
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 local response?
Local responce is a small change in membrane potential caused by a subthreshold stimulus.
What response is caused by a neutral stimulus?
A response caused by a neutral stimulus is known as a conditioned response. This occurs when the neutral stimulus becomes associated with a unconditioned stimulus through conditioning, leading to a learned response.
What is the ability of a muscle to respond to nerve stimulus called?
neuromuscular efficiency neuromuscular efficiency
What came first a stimulus or a response?
A stimulus comes first before a response. A stimulus is any event or situation that evokes a response from an organism. The response is the reaction or behavior that is produced in reaction to the stimulus.
What is evoked potential?
Evoked potential-- A test of nerve response that uses electrodes placed on the scalp to measure brain reaction to a stimulus such as a touch.
