Pandas are very shy and because of their markings they are difficult to see in the forest. There is only one sub-species of panda, and it is found only in China. The black and white bear is considered endangered. There are only about 1000 giant pandas left in the wild.
The trigeminal nerve (the fifth cranial nerve, or simply CN V) is a nerve responsible for sensation in the face and motor functions such as biting and chewing.he sensory function of the trigeminal nerve is to provide tactile, proprioceptive, and nociceptive afference to the face and mouth. Its motor function activates the muscles of mastication, the tensor tympani, tensor veli palatini, mylohyoid and the anterior belly of the digastric.
The trigeminal nerve sensory and motor roots exit the brainstem from the ventrolateral pons. It then enters Meckel's cave located posterior and inferolateral to the cavernous sinus, and here the trigeminal (gasserian or semillunar) ganglion is formed and gives off the three major branches.
