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

impulses from passing to the skeletal muscles. The purpose of blocking these passes is to make the muscles weak or paralyzed in surgery. Neuromuscular blockers can be used in many surgical procedures‚ like inserting an endotracheal tube‚ by relaxing the jaw muscles. They are also useful for relaxing the diaphragm and intercostal muscles (responsible for respirations) so that the patient can be manually ventilated. Neuromuscular blockers also aid in relaxing any muscles around the surgical site so

increased consumption of oxygen and nutrients by muscle cells requires more blood supply. The functions of blood include delivering oxygen‚ removing CO2‚ removing heat and delivering nutrients and water. Therefore‚ blood flow is important in cellular respiration‚ which is the process where ATP is produced through the conversion of metabolites‚ also involving the consumption of oxygen and release of CO2 as a waste product. ATP is vital to skeletal muscle contraction‚ since the power stroke is facilitated

List the four tissue types found in the human body. Describe an example of each type with their function and location. The four main tissues in the human body are connective‚ epithelium‚ muscle and nervous tissue. Connective tissue is an abundant nonliving extracellular matrix‚ located throughout the human body; such as the head‚ tendons‚ bone‚ and many more. It is the most widespread tissue in the human body and is the most durable tissue type. There are so many functions for this tissue‚ that

There are three different types of muscle tissue and each of these three has their own function: 1. Skeletal: This type of muscle tissue covers your Skeleton to give your body its shape. 2. Smooth: This type of muscle tissue works by contracting in order to do things such as pushing food through our bodies. 3. Cardiac: This type of muscle tissue squeezes the blood out of our hearts
