THE ABDOMEN MUSCLE ANATOMY


ABDOMINAL  ANATOMY



Abdominal muscles can be divided into 5 major muscles.




Ø THE  RECTUS  ABDOMINIS

Ø THE TRANSVERSUS ABDOMINIS

Ø INTERNAL OBLIQUE

Ø EXTERNAL OBLIQUE

Ø ERECTOR SPINAE

 

 


THE  RECTUS ABDOMINIS



In the broad classification of rectus abdominis, it is the muscles of abdominal, which is the outermost/uppermost  layer of abs muscles (generally, where the six pack lies on). It is a complete package of 8 packs but it often being misunderstood as a 6 pack, because to immerge out whole 8 pack abs, it requires lot of gym training. Last 2 packs are just lies above the pubic area, which is rarely found naked. The rectus abdominis is a long, thin and outer muscle area, whose fiber run vertically down the body from the chest bones and ends near the pubic region.

 

FUNCTION :  flexes the trunk (vertical, lateral and oblique flexes)

 

REGION :  Starts from 5th , 6th and 7th ribs

                      Ends at the pubic bone

   





THE TRANSVERSUS ABDOMINIS



The transversus abdominis muscle is flat and triangular. These muscles are actually come into use, while squeezing, tightening and sucking your gut inside. It is a thin sheet of  muscle  running along the sides of  the rectum abdominis. These muscle fibers run across the stomach, join into the rear area of the abs and wrap around the sides of the body. It attaches along the rib cage and into the back muscles.

 

It is a proven fact that targeting the transversus abs region, while doing abs workout, results into fast reduction of belly fat i.e. slim abdomen.

 

FUNCTION : Compression and squeezing of abdominal muscles.

REGION : Starts from inner cartilage surfaces  of  last  6  ribs and goes along the sides of  the rectum abdominis.

 

 

 

 

 

 

INTERNAL OBLIQUE



The internal oblique is a diagonal fibers, that fan out from the pelvis and ribs to the rear of the “eight-pack.” They provide a layer of support over the transversus. They are one of the main stabilizers of your trunk. The depth of these muscles renders them invisible, but they are no less important. They are one of the main stabilizers of your trunk. In simple words, the internal oblique create a view of inverted  “ V ” on your abdomen ( which starts  from the pelvis and ribs to the cartilage of  last 3 to 4 ribs at bottom).

 

FUNCTION : Lateral flexion of  the trunk and provides            

                         Support/stability to gut.

 

REGION :  Starts from the pelvis

                    Ends  at the Cartilage of last 3 to 4 ribs.

 

 

 

 



 

EXTERNAL OBLIQUE



These muscles are visible, running diagonally from the ribs to the front of the pelvis  and the side of your eight-pack  i.e. The external oblique fiber runs from the front of the pelvis and ends back to the ribs. Secondly, the fiber of the external oblique on one side lines up with the fiber of the internal oblique on the other side. They are one of the main stabilizers of your trunk. In  simple words, the external oblique create a view of vertical  “ V ” on your abdomen.

 

FUNCTION : Lateral flexion of  the trunk and provides  

                         Support/stability to gut.

REGION :  Anterolateral borders of lower 8 ribs.

 

 

 

 



ERECTOR SPINAE



The erector spinae is the  muscle group of human back. It is not just one muscle, but a bundle of muscles and tendons. It is paired and runs more or less vertically. It is the core to strong, rock-hard abs. The erector spinae provides stability and strength to our abdomen.

 The erector spinae muscles group is made up of  ILIOCOSTALIS  and  LONGISSIMUS. The network of these muscles group is spread all around the skull, runs down from spine  and  finally ends into the pelvis.


                                                  
                                                     THE PELVIS

ILIOCOSTALIS :  The top layer of spinae muscles  group.

LONGISSIMUS : The second layer from top of spinae muscles        

                                 group.


FUNCTION : Trunk extension

REGION : Transverse processes of all ribs
