Study Notes
Head & Neck Autonomics
- Lecture 5, Med Neuro II, January 23, 2025, by Liam Zachary, PhD
- Focuses on autonomic innervation of head and neck structures
- Key Ganglia: Trigeminal (sensory), Ciliary (PNS), Pterygopalatine (PNS), Otic (PNS), Submandibular (PNS)
- Learning Objectives cover autonomic innervation areas: intrinsic eye muscles/eyelid, lacrimal gland, nasal/palatal mucosa, parotid gland/buccal mucosa, submandibular/sublingual glands, pharyngeal/laryngeal mucosa
Learning Objectives
- Describe autonomic innervation of intrinsic eye muscles and eyelid
- Describe autonomic innervation of lacrimal gland and nasal/palatal mucosa
- Compare/contrast the anatomical bases of oculosympathetic paresis (Horner's syndrome) and oculomotor nerve palsy
- Describe autonomic innervation of parotid gland and buccal mucosa, describing the anatomical basis of Frey's syndrome
- Describe autonomic innervation of submandibular and sublingual glands.
- Describe autonomic innervation of pharyngeal and laryngeal mucosa
