The gluteal lines are three curved lines outlined from three bony ridges on the exterior surface of the ilium in the gluteal region. [1] They are the anterior gluteal line; the inferior gluteal line, and the posterior gluteal line. The gluteus minimus, medius, and maximus are muscles that arise from the gluteal lines.
This surface is crossed in an arched direction by three lines—the posterior, anterior, and inferior gluteal lines. The posterior gluteal line (superior curved line), the shortest of the three, begins at the crest, about 5 cm in front of its posterior extremity; it is at first distinctly marked, but as it passes downward to the upper part of ...
The iliac fossa is bounded above by the iliac crest, and below by the arcuate line. It is bordered in front and behind by the anterior and posterior borders of the ilium. The iliac fossa gives origin to the iliacus muscle. [1] The obturator nerve passes around the iliac fossa. [2] It is perforated at its inner part by a nutrient canal.
The gluteus medius muscle: originates on the outer surface of the ilium between the iliac crest and the posterior gluteal line above, and the anterior gluteal line below. The gluteus medius also originates from the gluteal aponeurosis that covers its outer surface. Gluteus minimus muscle originates between the anterior and inferior gluteal ...
The gluteus medius is a broad, thick, radiating muscle, situated on the outer surface of the pelvis. It lies profound to the gluteus maximus and its posterior third is covered by the gluteus maximus, its anterior two-thirds by the gluteal aponeurosis, which separates it from the superficial fascia and skin. The gluteus minimus is the smallest ...
The posterior view contains, from superior to inferior, the cervical region encompassing the neck, the scapular region encompassing the scapulae and the area around, the dorsal region encompassing the upper back; the lumbar region encompassing the lower back. the sacral region occurring at the end of the spine, directly above the buttocks.
The anterior inferior iliac spine (AIIS) is a bony eminence on the anterior border of the hip bone, or, ... A vague line, the inferior gluteal line, ...
Muscles of the gluteal and posterior femoral regions with gluteus minimus muscle highlighted. It is fan-shaped, arising from the outer surface of the ilium , between the anterior and inferior gluteal lines , and behind, from the margin of the greater sciatic notch .
