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 9: Skeletal Muscle Physiology Electrical Stimulation 1. Complete the following statements by filling in your answers on the appropriate lines below. A motor unit consists of a ___1___ and all the ___2___ it innervates. Whole muscle contraction is a(n) ___3___ response. A ___4___ is the response of a muscle to a single‚ brief threshold stimulus. When the frequency of stimulation is so high that the muscle tracing shows fused peaks‚ ___5___ has been achieved. ___6___

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

POST1 Mucormysis is a rare but highly aggressive and a fatal infection that affects immunocompromised patients. Mucormycosis infections have increasingly become very common. The survival of such infections is also very poor. Iron metabolism plays a very important role in regulating mucor infections. Deferoxamine predisposes patients to mucormycosisby supplying the fungus containing iron.From these findings‚ it is possible to treat the infection by using iron chelator as long as the chelator does

Discussion The data supported the hypothesis that if Daphnia are placed in differently concentrated solutions of barium and calcium chloride‚ then the highest concentration of calcium chloride would affect them the most because of the production of hydrochloric acid and calcium oxide from the mixing of water and calcium chloride‚ two very dangerous acids‚ with the highest concentration having the biggest chemical reaction. Within five minutes of putting the Daphnia into the 10 (ppt) solution of

Does caffeine affect the heart rate of Daphnia? Introduction In this experiment I aim to find out if caffeine has an affect on heart rate. Instead of using human subject‚ whom may already have a high tolerance to caffeine or could have ingested caffeine that day making the tests unfair‚ I will use Daphnia‚ a crustacean. They have on contact with caffeine making it fair. It will be easier to observe as it has a translucent body‚ making it able to see the heart beating under a microscope. It will

*How does the brain communicate with the rest of the body? How is the autonomic branch of the peripheral nervous system involved in controlling emotions? The nervous system as a whole includes the Central Nervous System‚ consisting of brain and spinal cord‚ and the Peripheral Nervous System‚ whose nerve fibres connect all parts of the body with the central nervous system. The Peripheral Nervous System is further subdivided into two branches‚ the Somatic Nervous system and the Autonomic Nervous System

Exercise 2: Skeletal Muscle Physiology: Activity 3: The Effect of Stimulus Frequency on Skeletal Muscle Contraction Lab Report Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. 1. During a single twitch of a skeletal muscle You correctly answered: b. maximal force is never achieved. 2. When a skeletal muscle is repetitively stimulated‚ twitches can overlap each other and result in a stronger muscle contraction than a stand-alone twitch. This phenomenon is known as

Date: Conducted by: Brenan‚ Jay and Satoro AIMS: * Demonstrate how vibration induces illusions of movement * To determine whether vibration has had any effect on ability to match joint angle between left and right arms * Observe the effect of fatigue on ability to sense force. INTRODUCTION Proprioception is defined as the sense of the relative position of neighboring parts of the body. It is the ability to distinguish how ones body is situated‚ either in motion or stationary
