The latent period and the infectious period helps determine the generation time of an infection. It also reduces the degree of contraction, i.e., the height of the curve (Fig. What physiological processes in a muscle cause the latent period in a muscle fiber? contraction period - tension increases (cross-bridges are swivelling) It lasts for about 0.04 seconds. Phase of shortening or contraction: It is the phase when work is done. The latent period and the infectious period helps determine the generation time of an infection. The muscle twitch lasts for about 0.1 seconds.It has three stages: Latent period: It is the period of no contraction and lasts for about 0.01 seconds. A seemingly inactive period, as that between exposure of tissue to an injurious agent and the manifestation of response or that between the instant of stimulation and the beginning of response. The latent period is a chemical event initiated by the stimulus regardless of its intensity. 1. PEx-18–PEx-20) Predict Question 1: No, changes to the stimulus intensity will not change the duration of the latent period. A latent period allows study of alterations of anatomy and physiology before, during, and after onset of epileptogenesis and the model, therefore, may be ideal for experiments focused on underlying cellular mechanisms and antiepileptogenic strategies. 2. Phase of relaxation: It is the phase when muscle returns to its previous relaxed state, and recovery is complete. The time that elapses between a stimulus and the response to it. Edit: The latent period is the short delay between the muscle action potential and the beginning of muscle tension development. (Science: physiology) The time between onset of a stimulus and peak of the ensuing action potential. 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. This is a lab question I cant find the answer in the lab manual or in the text book. A latent period allows study of alterations of anatomy and physiology before, during, and after onset of epileptogenesis and the model, therefore, may be ideal for experiments focused on underlying cellular mechanisms and antiepileptogenic strategies. Skeletal Muscle Physiology 2 EXERCISE Load lengthens the latent period but reduces the periods of contraction and relaxation. Activity 1: The Muscle Twitch and the Latent Period (pp. Recent Examples on the Web This is followed by a latent period with no apparent symptoms as metabolic acidosis develops. Latency period definition, the stage of personality development, extending from about four or five years of age to the beginning of puberty, during which sexual urges appear to lie dormant. Latent period definition is - the incubation period of a disease. This is what I'm talking about. Latent period may refer to: . Please help. A latent period allows study of alterations of anatomy and physiology before, during, and after onset of epileptogenesis and the model, therefore, may be ideal for experiments focused on underlying cellular mechanisms and antiepileptogenic strategies. latent period - no change in length; time during which impulse is traveling along sarcolemma & down t-tubules to sarcoplasmic reticulum, calcium is being released, and so on (in other words, muscle cannot contract instantaneously!) (Science: microbiology) Of an infection, a period in which the infection is present in the host without producing overt symptoms.
