Question Answer
CN VII passes through what salivary gland without innervating it?Parotid Gland
What CN passes through the Parotid Gland?CN VII (Facial)
What 4 "types of nerve fibers" run through the Facial nerve?1.BranchioMotor (face), 2.Parasympathetic (Lacrimal, Subman, and Subling), 3.Taste (special sensory: ant. 2/3's of tongue), & 4.general somatic (from the auditory meatus and ear)
What is the nuclear system for Touch, Pain, and Temp. sensation from the head and neck?Trigeminal Nuclear system (other nerves that carry this type of information tie into the Trigeminal Nuclear system)
What are the central and peripheral connections for Branchio-motor fibers of Facial Nerve (7)?Principal Nucleus of Facial Nerve & Muscles of facial expression
What are the central and peripheral connections for Paraympathetic fibers of Facial Nerve (7)?(Centrally Superior LacrimoSalivary Nucleus) & Glands (Subling, Subman, Lacrimal)
What are the central and peripheral connections for Taste (special sensory) fibers of the Facial Nerve (7)?Tractus Solitarius (aka Solitary Nucleus, Nucleus Tractus Solitarius, NTS)
What are the central and peripheral connections for General Somatic fibers of the Facial Nerve (7)?(Spinal Component of the) Trigeminal Nuclear System & External ear
Facial nerve (7) has two bundle types, what are the fiber types that make up NERVOUS INTERMEDIUS (one of the two bundles)?Taste (Special Sensory)(afferent), Parasympathetic (efferent), & General Somatic (Afferent)
