The margins of the inferior lumbar (Petit's) triangle are composed of the iliac crest inferiorly and the margins of two muscles – latissimus dorsi (posteriorly) and external abdominal oblique (anteriorly). The floor of the inferior lumbar triangle is the internal abdominal oblique muscle.
Petit's hernia is a hernia that protrudes through the lumbar triangle (aka Petit's triangle). [1] This triangle lies in the posterolateral abdominal wall and is bounded anteriorly by the free margin of external oblique muscle, posteriorly by the latissimus dorsi and inferiorly by the iliac crest.
This is a list of human anatomy mnemonics, categorized and alphabetized.For mnemonics in other medical specialties, see this list of medical mnemonics.Mnemonics serve as a systematic method for remembrance of functionally or systemically related items within regions of larger fields of study, such as those found in the study of specific areas of human anatomy, such as the bones in the hand ...
The inferior carotid triangle (or muscular triangle), is bounded, in front, by the median line of the neck from the hyoid bone to the sternum; behind, by the anterior margin of the sternocleidomastoid; above, by the superior belly of the omohyoid.
Inguinal triangle is labeled in green. Borders: inferior epigastric artery and vein: labeled at center left, and run from upper right to bottom center. inguinal ligament: not labeled on diagram, but runs a similar path to the inguinal aponeurotic falx, labeled at bottom. rectus abdominis muscle: runs from upper left to bottom left.
The inguinal ligament (/ ˈ ɪ ŋ ɡ w ɪ n ə l / [1] [2]), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop.
A similar triangular area between circular fibres of the cricopharyngeus and longitudinal fibres of the esophagus is Lamier's triangle or Lamier-hackermann's area. Clinical significance [ edit ]
2) Dorsal ramus of nerve C1-suboccipital nerve 3) Suboccipital venous plexus. The purpose of these muscles is to provide fine motor function in movements of the head. The actions of trapezius, sternocleidomastoid and other larger muscles that move the head are refined by the relatively small suboccipital triangle muscles.
