dissection of the muscle away from the tibo-fibula bone while leaving the it attached to the knee and heel. The muscle was consistently moistened by Ringer’s solution throughout the entire experiment. The Achilles tendon was removed at the heel of the frog. The tibiofibular bone was cut below the knee and the femur below the knee (Frog Skeletal Muscle Experiement). The baseline value of the force transducer was set to zero. This zeroing procedure was conducted at the start of each exercise. The force

YAWNING Physiology‚ Theories and Contagiousness First‚ let’s look at what this bodily motion is: Yawning is an involuntary action that causes us to open our mouths wide and breathe in deeply. We know it’s involuntary because we do it even before we’re born: According to Robert Provine‚ a developmental neuroscientist at the University of Maryland‚ Baltimore County‚ research has shown that 11-week-old fetuses yawn. And while yawning is commonly associated with relaxation and drowsiness‚ your heart

musculoskeletal system is made up of bones‚ joints‚ and muscles. This system gives the body form and support‚ and protects the body while allowing it to move. Basically‚ the muscles in this system perform three important body functions: the movement of body parts‚ maintenance of body parts‚ and production of body heat. These muscles all consist of a mass of protein fibers grouped together‚ and most are of mesodermal origin. And almost all of the muscle fibers you will ever have or need were present at

thickness by about 20 percent. The skin becomes thin and fragile and can no longer retain internal heat. For the Musculoskeletal‚ muscle mass is a primary source of metabolic heat. When muscles contract‚ heat will generate. The heat that the muscle puts out maintains body temperature‚ to require normal body function. Around the third decade of person’s life span‚ the muscle tissue reduces in size‚ elasticity and strength. As a result the body gets older and muscular activity becomes less takes more
