Back to Basics: Swallowing and Aerodigestive Co-Dependence

 Wednesday, March 6 ,2019

8:15-9:45 a.m.

In this session, the attendee will understand the anatomy and physiology of co-dependence on multiple systems involved with safe swallowing. A discussion on changing physiology during maturation and aging will be undertaken. (each presentation is 20 minutes)

 Moderators:

Sudarshan Jadcherla, MD, DCH, FRCP(Irel), AGAF

Rebecca German, PhD

 


 

Neuroscience of Feeding, Swallowing and Airway Protection: Emphasizing the Ubiquitous Connectivity of Vagus

Arthur Miller, PhD

This presentation will offer a discussion on wiring and sensory-motor processing pathways and effectors related to sucking, swallowing, chewing, oral processing, cues and airway protection. 

 

After this presentation, attendees will be able to:

  • Identify the key sensory inputs that modify swallowing and chewing. 

 

Integration of Airway Protection During Swallowing: Understanding Cross-Systems Connectivity

Rebecca German, PhD

This presentation will offer a discussion on cross-systems connectivity related to normal and abnormal swallowing. The aspiration preventing mechanisms commonly in place and what happens after aspiration will be explained as well as the neurophysiologic basis for symptoms such as cough, sneeze, apnea, belch and cardio-respiratory rhythm changes.

 

After this presentation, attendees will be able to:

  • Understand the physiologic coordination between swallowing and respiration as well as the pathophysiology of the failure of coordination. 

 

Developmental Physiology of Swallowing and Breathing During Infancy and Childhood

Katlyn McGrattan, PhD, CCC-SLP

This presentation will offer a discussion on fetal preparation to swallow, changes in infancy and childhood, and the expected timelines of milestones. 

 

After this presentation, attendees will be able to: 

  • Identify the prenatal stage when all aerodigestive structures involved in neonatal feeding are present.
  • Describe how infant feeding changes throughout the first year of life. 

 

Normal Adult Swallowing: Changing Physiology During Adulthood

Sonja Molfenter, PhD, CCC-SLP

This presentation will offer an understanding of normals in the adult age spectrum and will include swallowing in geriatric adults

 

After this presentation, attendees will be able to:

  • Define the normal range of variation in swallowing biomechanics and function in healthy older adults.
  • Discuss the difference between presbyphagia and dysphagia.
