Anatomy of Chest and Abdominal Muscles
Anatomy of Chest Muscles
Pectoralis Major
The pectoralis major muscle can act as an accessory in respiration. It is located between the scapula and the chest wall. Origin: lateral surface of the first eight ribs; insertion, regardless of the scapula spine. Action: rotation of the scapula and inspiratori.
External Intercostal Muscles
Each of these 11 pairs occupy the intercostal space, the ribs superior to inferior, from the Tuber of the rib to the cost-chondral junction.
Internal Intercostal Muscles
The internal intercostal muscles are in a position perpendicular to the deepest and external intercostal, previously and subsequently to reach al’estern angle of the ribs. The intercostal muscles are similar to internal and intimate are the deepest portion. They are respiratory muscles.
Diaphragm
The diaphragm is a thoracic abdominal muscle. It separates the abdomen. The upper surface is convex thoracic and abdominal or lower side is concave. It has a pearly heart shaped tendon clover. Source: Appendix xifoides, rib cartilage last six, last four ribs, lumbar vertebrae; insertion phrenic center. Action increases the three diameters of the thoracic cage, facilitating the entry of air into the lungs, glands: phrenic nerve.
Arteries
They originate in ventriculos, and they end in the capillary. Generally, they are deep. They contain oxygenated blood, except the pulmonary arterial trunk. When your wall divides the blood as fluye intermitente.
Veins
They originally from in the capillary and in the auricula r finalizan. They feature valves in its route. They contain blood dismissed with metabolic and oxygen poo, except the pulmonary vein wall. When your blood sectioned fluye. They contain continues as a wholesale volume of blood that they do not have the arterias colapsan sangre.
Abdominal Muscles
Oblique Major
Origin: the external face of the last eight ribs, insert the iliac crest to reach the sunrise line (inserted with the anti-side), is the most superficial. Action: flexion and rotation of the spine, compression of the abdominal cavity.
Less Oblique
Origin: iliac crest, inguinal ligament, lumbar sacral too common; insertion, the rib cartilage of the last three or four ribs, online alba and pubis. Action: flexion and rotation of the spine and compression of the abdominal cavity.
Transverse of the Abdomen
Origin: last six costal cartilages, lumbar sacral too common, iliac crest and inguinal ligament; insertion xifoide appendix, morning line, pubic ; is deeper and has horizontal fibers. Action: compression of abdominal viscera.
Rectus Abdominis
It vertically on each side of the sunrise from the pubis to the anterior chest wall (5e, 6e, 7e costal cartilage) Appendix xifoide; has tendinous intersections. Action: flexion of lumbar spine, tension in the abdomen.
Psoas Major
Origin: bodies of lumbar vertebrae, lesser trochanter insertion. Action: flexion of the trunk and thigh.
Iliac
Origin: iliac fossa; insertion, lesser trochanter of the femur. Action: flexion of thigh.
Pelvic Muscles
Levator Ani
Origin: ischium and pubic al’espina Sciatica sacrum; insertion, third and fourth sacral vertebrae. Action: support pelvic viscera and elevation and constriction of the anus.
Inguinal Canal
Through the fascial MUSCULO for the spermatic cord in man and round ligament in women, the treatment of oblique passageway located at the bottom the anterior abdominal wall; has two holes, or internal inguinal ring deep inguinal ring and the outer surface or
