We've covered how to repurpose your old router as a range-boosting repeater or a wireless bridge, but if you just need a few extra wired ports for devices your current router can't accommodate, consider repurposing your old router as a network switch.
The human tongue is divided into two parts the anterior and the posterior. The anterior part of the tongue is the visible part at the front and is about two-thirds of the tongue's length. The posterior tongue area is closest to the throat, and roughly one-third of length. There are eight muscles in the human tongue. They can be classified as intrinsic or extrinsic.
The root of the tongue is embedded in the oral diaphragm; it is attached by various muscles to the hyoid bone and mandible, and to the soft palate by the arches of the latter. On the dorsum, or upper surface, of the tongue is a large number of tiny projections known as papillae.
