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.
Anterior surface of the tongue. The tongue is a mass of interlacing skeletal muscle, connective tissue with some mucous and serous glands, and pockets of adipose tissue, covered in oral mucosa.A V-shaped line (shallow groove)- the sulcus terminalis, divides the tongue into an anterior 2/3 and a posterior 1/3.he mucosa covering the upper surface of the tongue is thrown into numerous projections called the lingual papillae in the anterior 2/3rd of the tongue. In the posterior 1/3rd, there are no papillae, but there are lots of lymphoid follicles present.
