Arcuate Line: What Is It, Clinical Significance, and More - Osmosis
网页2022年1月19日 · The arcuate line, also known as the semicircular line of Douglas, is a curved line found posterior to the rectus abdominis muscle bilaterally, at about one-third of the distance between the umbilicus and the pubic symphysis. This anatomical finding may not always be present, and its position may vary.
Arcuate line of rectus sheath - Wikipedia
网页The arcuate line of rectus sheath (the arcuate line or the semicircular line of Douglas) is a line of demarcation [1] corresponding to the free inferior margin of the posterior layer of the rectus sheath [2] inferior to which only the anterior layer of the rectus sheath is present [3] and the rectus abdominis muscle is therefore in direct ...
Actuator Line Method - an overview | ScienceDirect Topics
网页The actuator line method was developed by Sørensen and Shen [57] to address limitations in near-wake resolution by representing individual turbine blades as lines, from which aerodynamic forces are projected on to a computational mesh. The local flow velocities are sampled along the actuator from the computational mesh using interpolation.
Arcuate line - clinicalanatomy.com
网页The arcuate line is the arch-shaped (hence the name) inferior border of the posterior sheath of the rectus abdominis muscle. This structure is seen in a laparoscopic (posterior) view (see image, label "B") and represents the transition from a superior area with well-formed aponeurotic posterior rectus sheath to an area devoid of the posterior ...
Actuator curve embedding – an advanced actuator line model
网页This article describes an actuator curve embedding (ACE) concept to model arbitrary lifting lines using body forces within large-eddy simulation (LES). The new method removes some inconsistencies in body-force projection of the actuator line model (ALM) commonly used to represent wind turbine blades in atmospheric boundary-layer simulations.
Anatomy, Abdomen and Pelvis, Rectus Sheath
网页2023年7月24日 · The arcuate line is an area of demarcation visible from the peritoneal surface of the abdominal wall, residing one-third the distance between the umbilicus and the pubis. The arcuate line can be a sharp demarcation, or it can be a gradual transition zone where the fibers of the posterior sheath gradually disappear.
Rectus sheath: Anatomy, definition, function - Kenhub
网页2023年11月3日 · The line between the upper three quarters and the lower quarter of the rectus abdominis muscle is called the arcuate line. Inferior to the arcuate line, the lower quarter of the rectus abdominis muscle is covered by the rectus sheath on its anterior surface only, while the posterior surface is in direct contact with the transversalis fascia ...
The arcuate line hernia: operative treatment and a review of the ...
网页Purpose: An arcuate line hernia (ALH) is a rare diagnosis with no consensus on how to deal with this condition either when symptomatic or when found accidentally. Suggestions for laparoscopic and open operative techniques are given together with a review of the literature and a presentation of three new cases.
Arcuate line of the rectus sheath: clinical approach - PubMed
网页The rectus sheath has been extensively described in gross anatomic studies but there is very little information available regarding the arcuate line (AL). The aim of the present study therefore was to explore and delineate the morphology, topography and morphometry of the arcuate line and provide a ….
An Analytical Approach for Synthesizing Line Actuation Spaces …
网页2013年9月18日 · In this study, we present an analytical approach for synthesizing line actuation spaces of a parallel flexure mechanism (PFM) that can help designers to arrange linear actuators within the PFM in a correct and optimal way.
