REVIEW SHEET NAME_____________________ LAB 6: 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 (a) and all the (b) it innervates. Whole muscle contraction is a(n) (c) response. In order for muscles to work in a practical sense‚ (d) is the method used to produce a slow‚ steady increase in muscle force. When we see the slightest evidence of force

Your 10 Pounds of Muscle Plan Gaining 10 pounds of pure muscle is significant‚ and doing it in only four weeks isn’t exactly a long period of time to successfully achieve this goal. But don’t fool yourself: It is possible‚ as long as your commitment and consistency in the kitchen is as honest and intense as your effort in the gym. Will you gain ten pounds of dry muscle mass? Probably not but you can certainly gain up to ten pounds of lean muscle mass‚ which consists of dry muscle‚ glycogen and water

Factors Controlling Healthy Development Of Muscle And Bone. The food you eat affects every system and function in your body. A well-balanced diet ensures that your body has the raw materials to produce and maintain healthy‚ strong muscles and bones. On the other hand‚ poor dietary habits can produce deficiencies in vital nutrients‚ leading to poor bone and muscle development in children or the damaging of the body’s ability to maintain strong muscles and bones in adults. Protein It is a major

The Skeletal System is the framework of the body‚ consisting of 206 bones as well as a network of tendons that is made of tough band of fibrous collagen tissue connecting a muscle to bone‚ ligaments connecting bones to joint and cartilage that allows some flexibility of movement. The skeletal system serves 4 functions: (1) Giving the body its shape (2) Protecting the vital internal organs (3) Allowing for movement (4) Storing minerals and producing blood cells The skeletal system has 6 basic components:

example of systems working together is the skeletal system and the muscular system. Muscles are attached to bones; the muscles make the bones move. Without bones there is nothing to hold together the structure of muscles. Without both of these systems working together our body would be impossible to move on its own. The skeletal system is the system in our body that provides protection of the vital organs and support for the muscles and skin. The skeletal system is the most important system in the

Lab 6: Amphibian Muscle Contraction Results: For this experiment‚ Isometric contractions of the gastrocnemius muscle of a frog were analyzed and from this data the latent period‚ twitch‚ motor unit summation‚ tetanus‚ fatigue & mechanical summation were measured. The data was used to quantify the effect of passive tension on the twitch force‚ effect of stimulus intensity on the twitch force‚ effect of stimulus frequency on contractile force of xenopus gastrocnemius muscle. The threshold voltage
