Presentation Transcript

  1. Respiratory control mechanism Ji-Chuu Hwang Department of Biology National Taiwan Normal Univerisy

  2. Central controller Sensory nerve Phrenic nerve Sensor Effector Arterial chemoreceptor Carotid chemoreceptor pulmonary stretch receptors diaphragm

  3. Chemoreceptors and sensory nerves • Aortic chemoreceptor via the vagus nerve • Carotid chemoreceptor via the sinus nerve which is a branch of the glossopharyngeal nerve

  4. Pulmonary stretch receptors origin from the smooth muscle of the respiratory bronchi and detect the volume change during rrspiratory cyel

  5. Respiratory center Rhythmic control 1. Pons pneumotaxic center apneustic center 2. Medulla dorsal respiratory center ventral respiratory center Voluntary control : in cortex
