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.
There are four types of lingual papillae on the human tongue: circumvallate papillae (vallate papillae), fungiform papillae, filiform papillae and foliate papillae. All except the filiform papillae are associated with taste buds.n some diseases, there can be depapillation of the tongue, where the lingual papillae are lost, leaving a smooth, red and possibly sore area. Examples of depapillating oral conditions include geographic tongue, median rhomboid glossitis and other types of glossitis.
