Cranial structures illustrated in this chapter are: oral cavity including the oral mucosa, taste buds, salivary glands and teeth; epiglottis; esophagus; nasal cavity; brain; inner ear; and eye and surrounding supporting structures including Harderian glands. The cranium is composed of all four tissue types and most of the main neural structures contain or receive projections from primary sensory neurons. The skin of the cranium is discussed in Chapter 9. Primary sensory cells are located in taste buds, retina, olfactory and vomeronasal chemoreceptive epithelium, auditory and vestibular labyrinth in the inner ear, and sensory ganglia of the cranium such as the somatosensory trigeminal ganglion.
