Question: What Is True Latent Period?

What are the causes of latent period?

Latent period may refer to: Latent period (epidemiology), the time interval between when an individual is infected by a pathogen and when he or she becomes capable of infecting other susceptible individuals.

Muscle contraction, the time between a stimulus to the nerve and the contraction of the muscle..

Why did the latent period become longer as the load became heavier?

The latent period increases as the weight of the load gets heavier, this is for the necessary force to be generated by the muscle. … It would take longer with the heavier weight because as the weight of the load increases, so does the latent period time and the shortening velocity speeds.

Why relaxation period is longer than contraction period?

Following the latent period is the contraction phase in which the shortening of the sarcomeres and cells occurs. Then comes the relaxation phase, a longer period because it is passive, the result of recoil due to the series elastic elements of the muscle.

What happens when you increase the frequency of stimulation?

By increasing the frequency of stimulation will increase the tension developed. … This results in increased muscle tension.

What happens during the latent phase of a disease?

The period between exposure and infection is called ‘latent period’, since the pathogen is present in a ‘latent’ stage, without clinical symptoms or signes of infection in the host. The period between exposure and onset of clinical symptoms is called ‘incubation period’.

What happens during latency?

The latency phase originates during the phallic stage when the child’s Oedipus complex begins to dissolve. … During the latency phase, the energy the child previously put into the Oedipal problem can be used for developing the self. The superego is already present, but becomes more organized and principled.

Does the duration of the latent period change?

Predict Question 1: No, changes to the stimulus intensity will not change the duration of the latent period. The latent period is a chemical event initiated by the stimulus regardless of its intensity.

What does it mean for an infection to be latent?

Latent infection, generally speaking, means the residence in the body of a specific infectious agent without any manifest symptoms. The symptomless incubation period, which in certain diseases, notably measles and smallpox, is fairly definite in length, is a period of latency in infection.

Is the latent period the same as latency?

In epidemiology, particularly in the discussion of infectious disease dynamics (modeling), the latent period (also known as the latency period or the pre-infectious period) is the time interval between when an individual or host is infected by a pathogen and when he or she becomes infectious, i.e. capable of …

What is latent period quizlet?

Latent period is the period of time between the generation of an action potential in a muscle cell and the start of muscle contraction. Describe the process of excitation-contraction coupling in skeletal muscles fibers.

What is happening during the latent or lag phase?

The time between the activation of a motor neuron until the muscle contraction occurs is called the lag phase (sometimes called the latent phase). During the lag phase a signal called an action potential moves to the end of the motor neuron (axon terminal).

What occurs during the latent period of isometric contractions?

What occurs during the latent period of these isometric contractions? a. The length of the muscle fiber is sliding into an optimal length. … All the steps of excitation-contraction coupling occur.

Which of the following occurs during the latent period of muscle contraction?

Which of the following occurs during the latent period of muscle contraction? Acetylcholine is released at the axon terminal. An action potential is generated. Acetylcholine is released at the axon terminal and an action potential is generated.

Which produces the most energy for contraction?

adenosine triphosphate (ATP)The source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) – the body’s biochemical way to store and transport energy. However, ATP is not stored to a great extent in cells. So once muscle contraction starts, the making of more ATP must start quickly.

What is stimulus voltage?

Describe the effect of increasing stimulus voltage on isolated skeletal muscles. From threshold voltage as the stimulus increases, so does the force of the contraction until it reaches maximum voltage. At this level, the more stimulus, the muscle will still contract with the same force.

What happens if the latent period for an infection is longer than the incubation period?

If the latent period is longer than the incubation period, then people are infectious only after symptoms start. This means they can be recognised as being ill before they are infectious.

What does latent period mean?

1 : the incubation period of a disease. 2 : the interval between stimulation and response.

What happens during latent period in skeletal muscle?

During the latent period, the action potential is being propagated along the sarcolemma. During the contraction phase, Ca++ ions in the sarcoplasm bind to troponin, tropomyosin moves from actin-binding sites, cross-bridges form, and sarcomeres shorten.
