This is known as wave summation. As the stimulus frequency increases, what will happen to the muscle force generated with each successive stimulus? Free nerve ending and the Pacinian corpuscle do not contain the isoamylacetate receptor protein because they did not show response to the the odor stimulus.

During a single twitch of a skeletal muscle You correctly answered: How was each achieved in the experiment? How are they similar?

My prediction was wrong. When muscle twitches overlap and stimuli occurs one after another in a short amount of time, the muscle contraction is higher if a single stand alone contraction had occurred. Optic sensory neuron will respond to green light.

Describe the force of contraction with each subsequent stimulus. Review Sheet Results What is the difference between stimulus intensity and stimulus frequency? In this experiment the isolated skeletal muscle was repetitively stimulated such that individual twitches overlapped with each other and resulted in a stronger muscle contraction than a standalone twitch.

Will there be a limit to this response?

Wave summation increases the force produced in the muscle. In time that the stimulation frequency was increased to the situation in which muscle relaxation did not occur, the amount of force increased with each stimulus. How did the frequency of stimulation affect the amount of force generated by the isolated skeletal muscle when the frequency of stimulation was increased such that the muscle twitches did not fully relax between subsequent stimuli?

Yes, it is greater than the previous stimulations. Explain how each is achieved in vivo. To achieve an active force of 5. Stimulus frequency refers to the rate of stimulus.

This sensory neuron may have receptor protein that respond to light. Is the total muscle force generated by the higher frequency stimulation greater than the force generated in previous stimulations? If not, how did you achieve an active force of 5.

As the stimulus frequency increased, the muscle tension generated by each successive stimulus also increased, and a limiting maximum value was observed.

Stimulus intensity refers to the strength of stimulus. The moderate intensity chemical modality causes a receptor potential in the olfactory receptors.

As the stimulus frequency increases, the muscle force generated by each successive stimulus will increase. Thus, with a blow to the eye, one "sees stars. Does the Pacinian corpuscle likely have this isoamylacetate receptor protein?

How well did the results compare with your prediction? When stimulating the isolated skeletal muscle multiple times in a short period with complete relaxation between, each force between each stimulus increased slightly in step like form to a max peak.

Are these results called treppe or wave summation? Compare and contrast frequency-dependent wave summation with motor unit recruitment previously observed by increasing the stimulus voltage. The moderate-intensity pressure modality causes a receptor potential in the pacinian corpuscle as predicted.

What passive channels are likely found in the membrane of the olfactory receptor, in the membrane of the Pacinian corpuscle, and in the membrane of the free nerve ending?• Blood - Suffolk County Community College PhysioEx Exercise 11 pages PEx to PEx (back of the book) in 11th edition For study: Review Sheet Exercise 29A pages in 8th edition pages in 9th edition pages in 10th edition pages in 11th edition33%(9).
