PPT-1 - 12 Cranial Nerve Anatomy

Dr Peterson 1 Cranial Nerve I Olfactory Nerve The axons of these cells extend through the cribriform plate of the ethmoid bone into the olfactory bulb at the anterior end of the olfactory nerve. This tutorial will allow you to learn about the 12 pairs of cranial nerves in the human body.. An introduction to the cranial nerves is followed by a screen which allows you to click on the nerve name to learn the functions and tests for the assessment for each nerve..

Demonstrate good examination technique. Cranial Nerve VII: Facial. Fibers leave the pons, travel through the internal acoustic meatus, and emerge through the . stylomastoid. foramen to the lateral aspect of the face. Motor functions include facial expression, and the transmittal of autonomic impulses to lacrimal and salivary glands. This is the traditional scheme of Charles Judson Herrick (1868-1960), based on comparativeanatomy and descriptive embryology. C. J.
