Separate the calf muscles from the bone and cut the tibiofibula bone just below the knee. With minimal dissection the sciatic nerve and gastrocnemius muscle preparation should be completely free. Rinse and then immerse the preparation in ringer solution. Keeping the muscle in the frog allowing the circulation to continue

He then proceeded to dissect the man to find “the cause of so sweet a death”(Richardson‚ 2012). He produced many drawings of the dissection one of which was a drawing of the head‚ neck and shoulder muscles of the man from different angles. [Fig.1] From the neat and methodical appearance of the drawings‚ it is clear that they were not done during the time of dissection but instead created some time after that. (Universal Leonardo‚ 2014). He believed that each limb or bone should be depicted using

PRACTICAL 6: OSMOREGULATION AND EXCRETION Introduction Many animals need to control the water content of their body because the concentration of their body fluids is different to that of their environment. The process by which the amount of water and concentration of soluble ions in the body are regulated is called osmoregulation. In most cases the organs which are responsible for osmoregulation are also involved in the excretion of metabolic waste products. In this practical you will

Looking at the dissection pictures‚ one can see that they have a well developed circulatory system to aid them with living in the ocean. Photo below shows cephalopod circulatory system.

Biology is the study of life and living organisms‚ from the smallest bacteria to giant sequoias. Biologists use observation and experimentation to gain an understanding about the natural world. Branches of biology include anatomy‚ biotechnology‚ botany‚ cell biology‚ ecology‚ genetics‚ medicine‚ microbiology‚ molecular biology‚ and zoology. Many people entering the field of biology become specialized in a particular area. As a course‚ biology encompasses four main themes: 1. The process

Frog Skeletal Muscle The aim of this experiment is to explore the basic physiological principles of skeletal muscle using the isolated frog (Rana pipiens or Xenopus laevis) gastrocnemius muscle. Students will dissect a double-pithed frog. Then‚ they will connect the muscle to the Force Transducer to measure twitch recruitment‚ effect of stretch‚ muscle summation‚ muscle tetanus‚ and muscle fatigue. Written by staff of ADInstruments.
