Getting Down to the Details: Anatomy and Physiology of Infant Suck (a series in five parts)

Time-frame: 60-75
CERP: no

60-75 minutes for each segment Segment 1: Embryological and fetal development of infant suck This presentation focuses on the embryological formation of the structures that are used for infant sucking and suck-swallow-breathe coordination. It further presents the fetal maturation of these structures and the physiology that arises from their normal development. The participant will have a better understanding of suck-swallow-breathe as a developmental reflex. Segment 2: Cranial nerves, brain stem nuclei and the cranial bowl This presentation focuses on the cranial bowl and the cranial nerves that create infant suck-swallow-breathe coordination giving the participant insight into how to optimally support infant suck physiology. Dr. Hazelbaker concentrates on the six cranial nerves that directly generate suck-swallow-breathe, discusses their pathways and their brain stem nuclei. The participant will be better able to understand the role cranial nerves play in coordinating suck-swallow-breathe and how disruptions can create sucking problems. Segment 3: Cervical Nerves and cervical structures This presentation focuses on the cervical nerves and their vertebrae that support the cranial nerve function. Particpants will have a better understanding of the role that proper cervical nerve function has in producing optimal suck-swallow-breathe physiology. Dr. Hazelbaker also discusses how to assess this area for proper function and what methods to use to produce optimal function when compromises occur in this area. Segment 4: Muscles and Fascia of the neck, cranium and thoracic inlet Muscles and fascia play a significant role in suck-swallow-breathe coordination. Dr. Hazelbaker covers the anatomy of these tissues and how they inter-relate to produce infant suck-swallow-breathe coordination. The participant will better understand the detailed muscular and fascial aspects of infant feeding. Segment 5: Putting it all together: how these various tissues create suck-swallow-breathe coordination and how disturbances to alignment can create sucking problems. In this presentation Dr. Hazelbaker brings together the various aspects of infant suck-swallow-breathe anatomy and physiology and discusses the way in which coordination of physiological functioning of these various tissues produces proper infant suck. Dr. Hazelbaker also addresses ways in which structural mis-alignment of these various tissues can produce suck physiology compromise helping participants better understand how to properly identify and correct adverse influences on infant suck.
