fibers are high glycolytic fibers and type I fibers are oxidative fibers. Brooks (1985) showed this concept by using isotope racers to follow lactate. The study was conducted on rats‚ where a lactate tracer was infused into the blood of the rats. He took blood from the rats at rest and during exercise to see what happens to the rats blood lactate. The observation that was made was the lactate was being produced and consumed. He believed that about half of the lactate that was produced at rest was being

A) Growth plate and Endochondral ossification: In order to maintain a healthy skeletal system which is crucial for different organs such as respiratory system‚ brain‚ spinal cord and heart‚ it is very important to have a good development of the skeletal system. Endochondral ossification is the process through which the axial and appendicular skeletons are formed through the formation of a cartilage inter-mediate. A good model for endochondral ossification is the limb bud where the precursor cells

of oxygen. 2. Describe mammalian hibernation‚ making sure to include specifics on body temperature drops‚ metabolic rates‚ and respiratory rates. Mammalian hibernation is a process the body undergoes when trying to protect against extreme weathers and to help conserve energy for a few weeks or an extended period of time while a food source is scarce. Hibernation is a state where metabolic rate is low or inactive‚ low heart rate and‚ slowed breath. Those animals that have small body weights drop

Comparison of CRF and VR5 After Shaping in Two Rats Hannah Smith Clemson University Comparison of CRF and VR5 After Shaping 2 Abstract The behavior of two rats was observed by fifteen college students at Clemson University in a laboratory setting. The rats were trained to press a bar in a Skinner Box on either a Continuous Reinforcement schedule or a Variable Ratio-5 schedule. The rats’ bar presses‚ rearing behaviors‚ and grooming behaviors were recorded. The rats then went through extinction‚ reshaping

DC (Family: Capparidaceae) was investigated in Wistar rats. Fifty normoglycaemic male rats (120g-200g) were divided into groups A (hypoglycaemic study; n=20) and B (antihyperglycaemic study; n=30). The studies had one control group and three groups administered with Cr (100‚ 200 or 400mg/kg) respectively. Group B had two additional groups of diabetic-untreated rats and glibenclamide-treated diabetic rats. Diabetes was induced in Group B rats (except control) fasted overnight for 12hours by intraperitoneal
