Elasticity; The ability to be able to return to normal shape. While contraction is taking place the muscular system performs 3 functions; Motion, Heat Production and Maintenance of posture. Motion; The ability of being able to move e.g. walking or running. However, with motion you must know about levers.
Abstract Sliding filament theory of muscle contraction suggests existence of an optimal muscle length associated with maximum stimuli-generated tension. This hypothesis is tested in vitro by measuring muscle tensile response to fixed voltage stimulations under length alterations of the gastrocnemius of Xenopus laevis. Muscle length is mechanically varied by shrinking or extending and an attached force transducer records the tension generated by the fixed stimuli. Our results indicate greatest tensile response of about 3.2 N when muscle length is 30 mm. The response diminishes as deviations from this optimal length increases.

It comes from the muscle tension which is produced during muscle contraction. A force internal to the human system is the outcome, which produces tension on the skeletal system, resulting in an angular motion about the joint. An example of a biomechanical technique is a resolution of force or a vector resolution. It provides a way to establish the two component forces directly associated with a net force. The net force is what makes the movement happen and is called the resultant force.
What is a tendon made of? Tendons are made of dense, regular connective tissue. This form of connective tissue consists of densely packed bundles of collagen fibres. These fibres all run parallel to each other in the direction of the pull that is generated on the tendon What are agonistic muscles? Agonistic muscles are a classification used to describe a muscle that causes specific movement or possibly several movements to occur through the process of its own contraction.
If the value of x is postnatal age of 30 hours, what is the value for Yˆ or SBP for neonates ≤1,000 grams? Show your calculations. 208 EXERCISE 27 • Simple Linear Regression 6. In the legend beneath Figure 2, the authors give an equation indicating that systolic blood pressure is SBP = 50.3 + 0.12x. If the value of x is postnatal age of 30 hours, what is the value for Yˆ or SBP for neonates 1,001–1,500 grams?
