You should not perform this test in an OSCE, although you may be expected to have an understanding of what cranial nerves are involved in the reflex. Some of these nerves bring information from the sense organs to the brain; other cranial nerves control muscles; other cranial nerves are connected to glands or internal organs such as the heart and lungs. By Olivia Guy-Evans, published June 24, 2021 Fact checked by Saul Mcleod, PhD. Motor neurons cross from the left motor cortex to the right side of the Motor nerve which enables tongue movements. The tongue is a muscular organ in the mouth of a typical tetrapod.It manipulates food for mastication and swallowing as part of the digestive process, and is the primary organ of taste.The tongue's upper surface (dorsum) is covered by taste buds housed in numerous lingual papillae.It is sensitive and kept moist by saliva and is richly supplied with nerves and blood vessels. They control everything from your facial expression to digestion.
