Musculoskeletal Afferents and the Control of Breathing
Symposium — Tuesday, April 9, 2019 — 8:30 AM - 10:00 AM — Convention Center, Room W311H
Respiration Section — Chair: Kristi Streeter — Co-Chair: David Fuller
Cosponsored by AJP - Lung Cellular and Molecular Physiology and J. Appl. Physiol.
Activation of musculoskeletal afferents include myelinated (group Ia, Ib, II), thinly myelinated (group III) and unmyelinated (group IV) fibers can have a powerful impact on respiratory motor output. This symposium will provide an overview of contemporary research on respiratory and limb muscle afferents and the control of breathing in animal models and humans. Dr. Kristi Streeter will discuss the role of diaphragm afferents on cardiorespiratory control in spinal intact and spinally injured rats. Dr. Laurent Juvin will discuss the role of limb muscle afferents in driving coupling of respiratory and locomotor rhythms. Dr. Jane Butler will discuss the role of musculoskeletal afferents in respiratory muscle recruitment in humans. Lastly, Dr. Jerry Dempsey will discuss the role of limb and respiratory muscle “metaboreceptors” (group III-IV afferents) on sympathetic and respiratory motor output during exercise.
