What are the transversus thoracis muscles?
The transversus thoracis muscle is a thin muscle situated on the interior aspect of the anterior thoracic wall and its function includes pulling the rib cartilages caudally, in turn supporting expiration.
What are the four muscles that form the thoracic wall?
The thoracic wall is made up of five muscles: the external intercostal muscles, internal intercostal muscles, innermost intercostal muscles, subcostalis, and transversus thoracis. These muscles are primarily responsible for changing the volume of the thoracic cavity during respiration.

What is the transversus abdominis?
The transverse abdominis is located in the abdomen immediately inside of the internal oblique muscle. It is one of the innermost muscles of the abdomen and it arises from the inguinal ligament, iliac crest, the inner surfaces of the lower six ribs and from the thoracolumbar fascia.
What is the transverse abdominis muscle?
The transversus abdominis (TrA) muscle is the deepest of the 6 abdominal muscles. It extends between the ribs and the pelvis, wrapping around the trunk from front to back. The fibers of this muscle run horizontally, similar to a back support belt.
Where are thoracic muscles?
The muscles of the thorax include both the diaphragm as well as the muscles of the thoracic cage. The diaphragm can be located below the lungs and consists of a sheet of skeletal muscle which displays a double-domed structure.
What is transverse diameter of thorax?
The range was from 10.5 to 16.2cm in males and 9.5 to 15.7cm in females. Males had larger mean transverse cardiac diameter than females.
Which muscles increase the vertical diameter of the thorax during inspiration?
Action: diaphragm is the main inspiratory muscle, during inspiration it contracts and moves in an inferior direction that increases the vertical diameter of the thoracic cavity and produces lung expansion, in turn, the air is drawn in.
How do I strengthen my transversus abdominis?
Your move: Add planks and hollow holds to your weekly workout plan. The primary action in both exercises involves drawing your belly button toward your spine, directly engaging your transversus abdominis. It’s called “abdominal bracing,” and to do it effectively, just imagine you’re about to be punched in the gut.

Typical signs of a weak transversus abdominis are toned abdominals above the navel but a bulge below it. The client may experience: an inability to hold in the stomach after a large meal or when gassy; low back fatigue after prolonged standing or walking.
What exercise works the transverse abdominis?
Planks
Planks are the classic way to target the transversus abdominis, but a study by Australian researchers found that “the inward movement of the abdominal wall in supine” (aka performing a hollow hold) produces potentially even greater muscle activation.
