RIB CAGE KINETICS PART 1 - DIAPHRAGM FUNCTION (BIOMECHANICS OF THORAX )Physiotherapy Tutorial

RIB CAGE KINETICS PART 1 - DIAPHRAGM FUNCTION (BIOMECHANICS OF THORAX )Physiotherapy Tutorial Instagram:   / _movementscience_   linked in :   / adhip-nadkarni-5b45241a6   diagram from Cynthia Norkins and Teachmeanatomy twitter :   / adhip_nadkarni   summary of the video with the time for reference: 1. VENTILATORY MUSCLES - HIGH FATIGUE RESISTANCE - HIGH OXIDATIVE CAPACITY - CONTRACT RHYTHEMICALLY - VOLUNTARY AS WELL AS INVOLUNTARY CONTROL - WORK AGAINST ELASTIC PROPERTY OF LUNGS AND AIRWAY RESISTANCE 2. PRIMARY MUSCLES - DIAPHRAGM - (70-80) % - INTER-COASTAL - SCALENES 3. ACCESSORY MUSCLES - STERNOCLEIDOMASTOID - TRAPEZIUS - PECTORALIS MAJOR/ MINOR - SUBCLAVIUS - LEVATOR COSTARUM - SERRATUS POSTERIOR SUPERIOR/ INFERIOR - TRANSVERSE ABDOMINIS, - INTERNAL AND EXTERNAL OBLIQUES - TRANSVERSE THORACIC 4. DIAPHRAGM ORIGIN - RIBS, STERNUM, VERTEBRAE INSERTION - CENTRAL TENDON - COASTAL FIBERS - ZONE OF APPOSITION - FUNCTIONAL UNIT FORMED BY VERTICALLY TRAVELLING FIBERS - CRURAL FIBERS - RIGHT AND LEFT CRUS - TENDONS ARISING FROM (L1-L3 )VERTEBRA 5. ZONE OF APPOSITION - DIAPHRAGM WILL CONTRACT AND DESCENT DOWNWARD - ABDOMINAL CONTENTS WILL COMPRESS AND INCREASE INTRA-ABDOMINAL PRESSURE - THIS STABILIZES THE CENTRAL TENDON AND CONTINUED CONTRACTION OF COASTAL FIBERS WILL LIFT THE RIBS AND MOVE THEM OUTWARD 6. CRURAL FIBERS - ON CONTRACTION IT DESCENDS THE CENTRAL TENDON - INCREASED INTRA-ABDOMINAL PRESSURE WILL BE TRANSMITTED ACROSS APPOSED DIAPHRAGM - THIS WILL HELP COASTAL FIBERS TO EXPAND THE LOWER RIB CAGE AND CREATE NEGATIVE PRESSURE 7.INSPIRAION AND EXPIRATION - INCREASE IN THORACIC SIZE LEADS TO DECREASED INTRA -PULMONARY PRESSURE - ACTIVE INSPIRATION - AS THE DIAPHRAGM RELAXES, THORACIC VOLUME REDUCED - PASSIVE EXHALATION #biomechanicsofspine #spinebiomechanics #vertebralcolumnbiomechanics
