Külglihased

Külglihased, often referred to as the oblique muscles, are a crucial component of the abdominal wall. They are located on the sides of the torso, extending from the lower ribs down to the pelvis. These muscles play a vital role in a variety of bodily movements and functions.

The external oblique muscles are the outermost layer of the lateral abdominal muscles. They originate from the outer surfaces of the lower eight ribs and insert into the iliac crest, pubic tubercle, and the abdominal aponeurosis. The internal oblique muscles lie beneath the external obliques. They originate from the thoracolumbar fascia, anterior two-thirds of the iliac crest, and the inguinal ligament, inserting into the lower three ribs and the abdominal aponeurosis.

Together, the külglihased facilitate trunk rotation, lateral flexion (bending to the side), and flexion (bending forward) of the spine. They also play a significant role in stabilizing the core, which is essential for maintaining posture and preventing injury during physical activity. The obliques are also involved in forced exhalation, helping to compress the abdominal cavity.

Strengthening the külglihased is important for overall core stability and athletic performance. Exercises such as side planks, Russian twists, and bicycle crunches effectively target these muscles. A strong core, supported by well-developed oblique muscles, contributes to better balance, reduced risk of back pain, and improved efficiency in everyday movements and athletic endeavors.
