34B Frog cardiovascular Physiology: computer simulation 1. What was the baseline heart rate for the frog? Ans: 59-63 bpm 2. Which wave is larger‚ the one for atrial constriction or the one for ventricular contraction? Why Ans: Ventricular. It shows the strength of the ventricle as it pumps blood‚ and it is a thicker muscle to pump stronger as it contracts 3. At what time during the contraction cycle was it possible to induce an extrasystole? Ans: The time during the relaxation part of

setting is to ably portray the dark and sepulchral undertones of the psyche of the stories’ characters‚ and through them‚ the nature of humans in general. Hop-Frog Compared to the other two short stories given for analysis Hop-Frog has very limited‚ if any‚ Gothic elements. However the climax of the story in itself is greatly shocking. Hop-Frog is shown to have tricked the King and his councillors into dressing as ourang-outans on the occasion of a masquerade in the palace. With a pre-planned connivance

BLAIR/NATIONAL GEOGRAPHIC This photo shows a museum worker inspecting a replica of a woolly mammoth (Mammuthus primigenius)‚ a relative of modern elephants that went extinct 3‚000 to 10‚000 years ago. Biologists briefly brought the extinct Pyrenean ibex back to life in 2003 by creating a clone from a frozen tissue sample harvested before the goat’s

As the fog continued to lift‚ it revealed the source of the ripples‚ a frog. The frog had jumped into the lake and was propelling itself towards the other side.

African clawed frog. After being injected‚ if the frog produced eggs within 24 hours‚ the woman was deemed to be pregnant. The ‘Frog Test’ was the world’s first cheap and reliable pregnancy test and became the international standard for years. Then‚ in 1958 a ‘hormonal pregnancy test’ (HPT) by the name of Primodos was manufactured by Schering – a German based Pharmaceutical Company – and became available for sale in the UK. It was advertised to be faster and more reliable that the ‘Frog Test’ in letting

Laboratory 10 & 11: Stimulated Diving and Heart Rate Prelab Questions: 1.) If the peripheral blood vessels were constricted without making any other further adjustments in the cardiovascular system then the blood vessels could potentially burst due to the built up pressure and no further decrease in heart rate. The vessels would be smaller due to the constriction but the heart would continue to pump the blood with the same or greater force. The dive response prevents this from happening

The frogs did not react as expected‚ the salt made the frogs develop much faster than usual. The increased amount of salt made the frogs feed much more than they usually would during development. The increases feeding made the frogs grow to be much larger than usual as well. It was thought that the gray tree frogs would dehydrate with the increased salinity but they were able to survive. The frogs may have survived but this change in size could have

Experiment 2: Skeletal Muscle ABSTRACT Frog skeletal muscle is used as an animal model to study muscle contraction. The objectives of this experiment is to demonstrate the physiological responses of skeletal muscle to electrical stimuli using frog gastrocnemius‚ to understand twitch‚ summation‚ tetanus and fatigue‚ to investigate the relationship between initial tension and force of contraction‚ to explore the differences between human and frog skeletal muscle. The threshold voltage is 0.4V. The
