A Review of Facial Nerve Anatomy Terence M. Myckatyn‚ M.D.1 and Susan E. Mackinnon‚ M.D.1 ABSTRACT An intimate knowledge of facial nerve anatomy is critical to avoid its inadvertent injury during rhytidectomy‚ parotidectomy‚ maxillofacial fracture reduction‚ and almost any surgery of the head and neck. Injury to the frontal and marginal mandibular branches of the facial nerve in particular can lead to obvious clinical deficits‚ and areas where these nerves are particularly susceptible to injury

different natural sedatives like alcohol and poppy plants. In 1700 B.C.‚ the Edwin Smith surgical papyrus was written. This papyrus was crucial in understanding how the ancient Egyptians understood the nervous system. This papyrus looked at different case studies about injuries to different parts of the body‚ most notably the head. Beginning around 460 B.C.‚ Hippocrates began to study epilepsy‚ and theorized that it had its origins in the brain. Hippocrates also theorized that the brain was involved in

of the neuron generate signals that open these voltage-gated channels? Dendrites and the cell body c. Opening of these channels causes the membrane to depolarize. (voltage change). 3. a. If the membrane reaches the trigger point‚ known as Threshold‚ what electrical potential will be generated? Action potential. b. During the depolarization phase‚ voltage-gated Na channels open and Na enters the cell. 4. What are the two processes that stop the potential from rising above +30 mV? a. Inactivation
