The Vagus Nerve: Branchial Motor / Special Visceral Efferents: The Pharynx, Larynx, Soft Palate and one tiny tongue muscle

by Michelle Emanuel, OTR/L, IBCLC, CST, NBCR
  • Duration: 60 Mins
  • Credits: 1 CERP, 1 L-CERP
  • Learning Format: Webinar
  • Handout: Yes
  • Origin:

Babies with tongue/oral restrictions and Cranial Nerve Dysfunction (CND) present with clinical indicators of decreased airway patency which interrupt latch and breastfeeding skills, airway development and Autonomic Nervous System regulation. These difficulties are noted clinically by mouth breathing, open mouth posture, stridor, snoring and other noisy breathing, suboptimal breathing patterns, decreased suck/swallow/breathe coordination and poor tongue and jaw posture / movement during activity and rest. Many of us are familiar with the Vagus nerve and the vital role it plays as our body’s sensory/afferent relayer of information to the central nervous system, as well, the Vagus serves as the primary parasympathetic influence on most of our viscera, including our heart, which helps us regulate. However, what we often gloss over is the motor input to the skeletal muscles of the soft palate, pharynx, larynx and tongue which directly impact breathing. This lecture will delve into this fascinating topic and provide clinical applications.

Learning Objectives:

Objective 1: Identify 3 observations of dysfunction with branchial motor efferents
Objective 2: Understand 3 clinical applications to promote optimal function of branchial motor efferent
Objective 3: Name 3 swallowing muscles innervated by the vagus nerve
