1 Muscles involved in respiration Respiratory block-anatomy-lecture 1 Editing file
2 Objectives Describe the components of the thoracic cage and their articulations. Describe in brief the respiratory movements. List the muscles involved in inspiration and in expiration. Describe the attachments of each muscle to the thoracic cage and its nerve supply. Describe the origin, insertion, nerve supply of diaphragm. Color guide : Only in boys slides in Blue Only in girls slides in Purple important in Red Doctor note in Green Extra information in Grey
3 Thoracic cage : 3 Conical in shape Has 2 apertures (openings): 1. Superior (thoracic outlet): narrow, open, continuous with neck obliquely placed facing upward and forward Bounded by: Superior border of the manubrium anteriorly Medial borders of first rib laterally First thoracic vertebrae posteriorly 2. Inferior: wide, closed by diaphragm Bounded by: Xiphisternal joint: anteriorly Curving costal margin laterally Twelve thoracic vertebrae: posteriorly Formed by: 1- Sternum & costal cartilages: anteriorly 2- Twelve pairs of ribs: laterally 3- Twelve thoracic vertebrae: posteriorly Note : the lower border of the rib is sharp.
4 Articulations 4 Intervertebral discs*= Between two vertebrae (Secondary cartilaginous) Costovertebral joints= Between ribs and thoracic vertebrae (Plane synovial) Note : each Rib articulates with two vertebrae. Costochondral joints= Between ribs and their costal cartilages (Primary cartilaginous) Interchondral joints*= Between costal cartilages of 6th -10th ribs (Primary cartilaginous) Sternocostal joints= Between costal cartilages and sternum 1st costal cartilage (Primary cartilaginous) From 2nd to 7th (Plane synovial) Manubriosternal joint*= Between manubrium and body of sternum (Secondary cartilaginous) Xiphisternal joint*= Between body of the sternum and xiphoid process (Secondary cartilaginous) * found only in boys slide
5 Respiratory Movements :Movements of DIAPHRAGM and RIBS 5 DIAPHRAGM RIBS Inspiration (in breath) Expiration (out breath) Contraction, descent (down) Of diaphragm Relaxation, ascent (up) Increase of vertical diameter of thoracic cavity Both Normal and forced Inspiration are active (needs muscles action) Decrease of vertical diameter of thoracic cavity Normal Expiration is Passive 1. Elastic recoil of lung 2. Relaxation of diaphragm & external intercostal (No muscles action) Forced Expiration is active (needs muscles action) Pump handle movement Bucket handle movement Elevation of ribs Elevation of ribs Increase in antero-posterior diameter of thoracic cavity Increase in lateral diameter of thoracic cavity
6 Inspiratory Muscles Active in both normal and forced inspiration = Diaphragm and External intercostal muscles Active Only in forced inspiration (Accessory muscles) such as : Scalene muscles and Pectoralis major DIAPHRAGM: A musculotendinous partition between thoracic & abdominal cavity. It is Convex toward thoracic & concave toward abdominal cavity. (most important muscle) Origin : 1- Costal: Lower 6 ribs and their costal cartilages 2- Vertebral: upper 3 lumbar vertebrae by Right crus (attached to the upper three lumbar vertebrae ) Right crus is stronger and bigger because liver is immediately below it left crus (attached to the upper two lumbar vertebrae ) And 5 ligaments : 2x Medial arcuate: connects each crus to 1st lumbar vertebra 2x Lateral arcuate:connects 1st lumbar vertebra to last rib Median arcuate: connects right & left crus 3- Sternal: Posterior surface of xiphoid process
7 Inspiratory Muscles 7 DIAPHRAGM: cont Central tendon Insertion : Fibers converge to join the central tendon (lies at the level of xiphisternal joint, at 9th thoracic Vertebra) Caval opening Aortic opening Nerve supply: Esophageal opening phrenic nerve (C3,4,5), penetrates diaphragm & innervates it from abdominal surface Why the cervical spines? Because first it forms near the neck then it goes down as the embryo develops (folding of embryo) Action : contraction of the diaphragm Lead to increase of vertical diameter of thoracic cavity (this action is essential for normal breathing) *Superior view Openings of diaphragm (apertures) : Caval apertures, at level of T8 Esophageal apertures, at level of T10 Aortic apertures, at level of T12
8 Inspiratory Muscles 8 External intercostal muscles (Rib elevators) Attachments from lower border of rib above to upper border of rib below Direction of fibers downward & medially(forward) Action rib elevators Nerve supply intercostal nerves Muscle Scalene muscles Pectoralis major Origin Cervical vertebrae clavicle + sternum + costal cartilages Insertion 1st rib (scalenus anterior and medius) 2nd rib (scalenus posterior) Bicipital groove of humerus Elevate 1st & 2nd ribs increases antero-posterior diameter of thoracic cavity, when arm is fixed Action EXTERNAL INTERCOSTAL Picture
9 Expiratory muscles 9 Two groups: A- Ribs depressors B- Anterior abdominal wall muscles All expiratory muscles act only during forced expiration First : Ribs depressors Muscle Direction Internal intercostal Innermost intercostal Subcostal Transversus thoracis - - backward & laterally Nerve Intercostal nerves (ventral rami of T1-T11) Action depression of the ribs Vein, artery, nerve (VAN) Lies in between of Internal & innermost intercostal Picture External intercostal Internal intercostal Innermost intercostal
10 10 Expiratory muscles Second : Anterior abdominal wall muscles It Is formed of 3 layers of muscles of fibers running in different directions (to increase strength of anterior abdominal wall) The 3 muscles form a sheath in which a fourth muscles lies (rectus abdominis) Muscles are attached to: sternum, costal cartilages and ribs + hip bones The aponeurosis of the 3 muscles on both sides fuse in the midline to form linea alba (it is meeting of 3 aponeurosis in both sides, extending from the xiphoid process to symphysis pips) Muscle External oblique Internal oblique Rectus abdominis Transversus abdominis Direction Downward & medially Upward & medially Vertical Transverse Nerve lower 5 intercostal nerves (T7-T11), subcostal nerve (T12) and first lumbar nerve. Action (during forced expiration): Compression of abdominal viscera to help in ascent of diaphragm
