Which muscles do you use for punching?

When punching someone, you do many types of movements. When punching, you usually extend the arm and forearm and flex fingers.. Now there are over 50 muscles in relation to the upper limbs but we will go over the basics. Since it will take a while to understand the anatomy, I'll give you a brief list of the muscles. This includes the arm and forearm. Triceps (extension of the arm) Anconeous (extension of the arm) Flexor digitorum longus and superficialis (flexes joints of the fingers)


What are four parts of the box and whisker plot called?

There are 5 (not 4) parts of an elementary box and whiskers plot. From left to right, they are: minimum, lower quartile, median, upper quartile, and maximum. A more advanced version of plot is used for data containing outliers. In such cases the whiskers extend to the minimum or maximum EXCLUDING the outlier(s) and the outliers themselves are marked with Xs - beyond the scope of the whiskers.


Why are cells spherical instead of cubical if a cube has a larger surface area to volume ratio than a sphere does?

The cells of the body have different sizes, shapes and surface area to volume ratios depending on their function, that is, their structure/function relationships. For example, lung alveolar cells are flat or squamous cells that optimize surface area to volume ratio for gas exchange between blood and the atmosphere; neurons have long tubular axons that increase surface area/volume ratio; cuboidal skin cells of the basal layer are cube shaped and optimally shaped for blood gas and nutrient exchange as well as for their function of adherence and skin replicative function; kidney proximal convoluted tubule cells are cuboid, but extend their membrane surface area for maximal reuptake of blood nutrients by the extension of microvilli on the luminal side of the proximal convoluted tuble. Red blood cells are biconcave discs that, thereby, increase surface area for gas exchange. White blood cells are pretty spherical indicating a requirement for maximizing volume, at the expense of surface area, for antibody production or bacterial destruction etc. . Skeletal muscle cells are long and spindle shaped and often fuse together with other muscle cells in development in order to span the distance across a joint, for example. But you are correct in stating that a cube would have greater surface area to volume ratio than a sphere as a function of length of side or radius (in the case of a sphere).
