Exercise 8 Simple Muscle Contraction • 3 Phases AB - lag phase or latent phase - (shortest) 0.00sec‚ usually less than 0.01sec - brief period that exists between the application of the stimulus and the start of contraction BC - contraction‚ 0.05sec - peak - shortening of the muscle occur CD - relaxation period‚ 0.05 sec - Occurs when Ca+ is transported back in the sarcoplasmic reticulum Single muscle contraction= 100vib/sec (tuning fork)= 0.10 sec 10vib (result) Neuromuscular junction - formed when

Lab 6: Amphibian Muscle Contraction Results: For this experiment‚ Isometric contractions of the gastrocnemius muscle of a frog were analyzed and from this data the latent period‚ twitch‚ motor unit summation‚ tetanus‚ fatigue & mechanical summation were measured. The data was used to quantify the effect of passive tension on the twitch force‚ effect of stimulus intensity on the twitch force‚ effect of stimulus frequency on contractile force of xenopus gastrocnemius muscle. The threshold voltage

and unfamiliar exercise‚ particularly which involves eccentric muscle actions can cause muscle damage and lead to delayed-onset muscle soreness (DOMS)‚ which may impair performance. This is due to the high force features of eccentric contraction (Starbuck & Eston‚ 2011). It can also cause muscle shortening‚ swelling and loss of strength in the muscles. Injuries commonly occur during eccentric loading of the muscle; that is‚ when the muscle is contracting while it is lengthening. (LaStayo‚ et al.‚ 2003)

Early Modern Europe – Major Forces for Change There are a lot of events that shaped the history of early Europe. Our ancestors had a lot on their plate when they discovered new lands and fought new diseases. One of the early forces that had a major impact were the crusades. The Crusades were a bunch of religious wars that were called on by the Pope and the Catholic Church in order to defend Christianity against the Muslims and get closer to the holy cities and other places in ancient Palestine

This whole presidential race has been something. To be specific it has been something I have hated. Politics is probably the only thing in this world that I feel such a hatred for. I don’t hate it because of the outcome of the election‚ I hated it before that. The reason I hate it is because it just turns everyone against each other and it just causes negativity. Negativity would be seen everywhere before the election. It was shown at the fountain when people would write in

Muscle Test #1 Study Guide 1. What are the primary functions of muscles? What are skeletal muscles made of? Five Skeletal Muscle Functions 1.Produce movement of the skeleton •By pulling on tendons that then move bones 2.Maintain posture and body position 3.Support soft tissues •With the muscles of the abdominal wall and the pelvic floor 4.Guard entrances and exits •In the form of sphincters 5.Maintain body temperature •When contraction occurs‚ energy is used and converted to heat
