Dissecting out the gastrocnemius muscle Completely cut the skin around the lower abdomen. Then cut down between the legs to free the skin around one leg from the rest of the skin‚ cut any attachments of the skin to the body. Holding the upper part of the frog firmly in one hand pull the skin down off of the leg. Be careful when pull the skin off around the knee as it is attached more firmly there. Place the frog dorsal side up in the tray and make sure to keep the muscles moist with ringer solution

2/14/2012 Anatomy and Physiology Muscle Grip Strength Lab Report Introduction: Skeletal muscle is a form of striated muscle tissue existing under the voluntary control of the somatic nervous system (Medscape 1). Skeletal muscle is part of the three big muscle types‚ it is connected to bones by tendons (Medscape 1). Muscle grip strength is significant to an individual because it helps the person know the ability of muscle power and force that they have in their

Experiment 1 Cyanobacteria Oxygen Production Through Photosynthesis Date Performed: September 2‚ 2014 I. Introduction a. Background Cyanobacteria or blue green algae are renowned for their tolerability and susceptibility even in wide range of environmental conditions‚ a characteristic of many primitive organisms. CNB are believed to be the agents of autotrophic origin of life thus they probably represent the survivors of the earliest photosynthetic plants‚ along with photosynthetic and chemosynthetic

obtained are nothing similar to the expected results‚ the whole experiment was a total fail. The frog muscle was heated for too long‚ so it stiffened before any recording of the results by the machine occurred‚ and there’s also a high probably that the muscle that we assume to have been exposed to heat for too long‚ probably died before the experiment commenced; the reason behind this is that one of the experimenters held the muscle in her bare hand(that was probably salty because of sweat‚ and because

the axon and guides the synaptic vesicles until it reaches the synapse. This triggers the release of the neurotransmitters stored within the vesicles. Once released‚ the neurotransmitters then bind to receptors of the receiving cell. It would be nearly impossible to have the transportation of vesicles without kinesin to guide it. And without the transportation of these synaptic vesicles to release their neurotransmitters‚ there would be no movement in the cell at all. This experiment is so important

responsible for making the pillbug habitat‚ taking them in and out of the habitat for our experiment‚ setting up the experiment setups for testing‚ and timing the experiment. In my opinion‚ I contributed a lot in my group. I did a majority of the lab proposal‚ and a substantial amount in the lab report. I was always the one getting up to gather our materials and pillbugs from the bins and making sure that our experiment was going as smoothly as intended. From this project‚

The purpose of this experiment is to examine the results of stimulation on a frog’s sciatic nerve by looking at its compound action potential‚ the conduction velocity‚ and by quantifying the total and absolute refractory period between the nerve at room and cold temperature. An oscilloscope‚ preamplifier‚ and stimulator were used to stimulate the frog’s nerve located in the nerve chamber. Threshold voltage was determined by stimulating the nerve at increasing voltages until a compound action potential
