Canavan’s disease is one of the most common and fatal progressive cerebellar degenerative disorder affecting the white matter of the brain which is caused due to the enzyme aspartoacylase. 1 Aspartoacylase (ASPA gene) promotes the deacetylation of N-acetylaspartic acid (NAA) to produce acetate and L-aspartate which is the only brain enzyme that has been shown to effectively metabolize NAA. 2 NAA metabolism plays a major role in the formation of myelin lipids. Oligodendrocytes present in the brain

Lab 34b Cardiovascular Physiology 1. What was the baseline heart rate for the frog? 59-63 bpm 2. Which wave is larger‚ the one for atrial contraction or the one for ventricular contraction? Why? 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? The time during the relaxation part of cardiac cycle. 4. By clicking the Multiple

Thermogenesis is the process of heat production in organisms. It occurs mostly in warm-blooded animals‚ but a few species of thermogenic plants exist. One form of thermogenesis is called thermo-regulatory thermogenesis. This is involved with keeping the temperature of the human body regulated. The average body temperature is 98.7 degrees (F)‚ which is quite a bit higher than the ambient (surrounding) temperature in most cases. There are two types of thermo-regulatory thermogenesis: shivering and

Lab 4: Skeletal Muscle Function Exercise 5: The Length-Tension Relationship Materials and Methods In this experiment I used a frog anesthetized with ms222. The frog’s skin is cut and removed from both the legs‚ the Achilles tendon is cut and the tendon and calf muscle are removed from the lower legs. The femur muscle is also cut. Attached to the legs are femur clamps which are connected to the transducer arm‚ stimulation electrodes are then positioned against the muscle. I plugged the output
