The internal oblique performs two major functions. Firstly as an accessory muscle of respiration, it acts as an antagonist (opponent) to the diaphragm, helping to reduce the volume of the chest cavity during exhalation. When the diaphragm contracts, it pulls the lower wall of the chest cavity down, increasing the volume of the lungs which then ...
The mylohyoid line is a bony ridge on the internal surface of the body of the mandible. The mylohyoid line extends posterosuperiorly. The mylohyoid line continues as the mylohyoid groove on the internal surface of the ramus. The mylohyoid muscle originates from the anterior (front) part of the mylohyoid line. [1]
Each consists of the external oblique, which is the closest to the surface and the largest abdominal muscle, and the internal oblique, which lies directly beneath. The muscle fibers of the ...
The two oblique muscles are the internal and external obliques. They're important for core stability and a slimmer waist. Try the 9 best oblique exercises.
The increased distance between the muscles is created by the stretching of the linea alba, a connective collagen sheath created by the aponeurosis insertions of the transverse abdominis, internal oblique, and external oblique. [2] This condition has no associated morbidity or mortality.
The oblique ridge is found on the occlusal surfaces of maxillary molars. It is formed by the union of the distal cusp ridge of the mesiolingual cusp and the triangular ridge of the distobuccal cusp. The oblique ridges usually forms the distal boundary of the central fossa.
The superior lumbar (Grynfeltt-Lesshaft) triangle is formed medially by the quadratus lumborum, laterally by the posterior border of internal abdominal oblique muscle, and superiorly by the 12th rib. The floor of the superior lumbar triangle is the transversalis fascia and its roof is the external
The linea aspera is a prominent longitudinal ridge or crest, on the middle third of the bone, presenting a medial and a lateral lip, and a narrow rough, intermediate line. It is an important insertion point for the adductors and the lateral and medial intermuscular septa that divides the thigh into three compartments. The tension generated by ...
