What is the linea semilunaris used for?
What is the linea semilunaris used for?
Linea semilunaris provides strength, mobility, and flexibility to the lateral abdominal muscles. However, it is one of the weak areas of the anterior abdominal wall, and it is, therefore, susceptible to herniation.
Why we should not make incision along linea semilunaris?
It then terminates as the anterior cutaneous branches of the skin of the anterior abdominal wall. The passage of thoracoabdominal nerves through the rectus sheath at the linea semilunaris renders the linea semilunaris an undesirable site for incisions.
How is linea semilunaris formed?
The linea semilunaris corresponds with the lateral border of the rectus abdominis muscle. It extends from the cartilage of the ninth rib to the pubic tubercle. It is formed by the aponeurosis of the internal oblique at its line of division to enclose the rectus.
What is Pyramidalis muscle?
Pyramidalis is a small triangular muscle located anterior to the lower part of rectus abdominis muscle within the rectus sheath. It is attached by tendinous fibres to anterosuperior margin of pubis and by the ligamentous fibres in front of the pubic symphysis.
What makes up the linea alba?
The linea alba (Latin for white line) is a single midline fibrous line in the anterior abdominal wall formed by the median fusion of the layers of the rectus sheath medial to the bilateral rectus abdominis muscles. It attaches to the xiphoid process of the sternum and the pubic symphysis.
What is Camper’s fascia?
Camper’s fascia is the superficial fatty layer of the anterior abdominal wall. This fascia is composed of loose areolar tissue and is found deep in the skin and superficial to Scarpa’s fascia.
How long does laparotomy incision take to heal?
Recuperation time following laparotomy is usually six weeks, but may vary depending on whether other procedures are performed at the same time. As with any post-operative recovery, it is important to always consult your doctor.
What are the indications for laparotomy?
Emergency conditions, such as those for acute intraperitoneal bleeding, uncontrollable gastrointestinal bleeding, blunt or penetrating abdominal injuries, generalised intraperitoneal sepsis due to perforated gastrointestinal tract are still the most common indications for laparotomy[3].
What is the linea alba?
What is Linea Semicircularis?
The arcuate line of the abdomen (or linea semicircularis) is a horizontal line that demarcates the lower limit of the posterior layer of the rectus sheath. It is also where the inferior epigastric vessels perforates the rectus abdominus.
Do I have pyramidalis muscle?
Pyramidalis muscle (Musculus pyramidalis) Pyramidalis is a paired triangular muscle of the anterior abdominal wall found on each side of the linea alba. According to the narrowest anatomical classification, pyramidalis belongs to the anterior abdominal muscles, together with the rectus abdominis muscle.
Which abdominal muscle is the most superficial?
External Oblique
External Oblique – the most superficial and also the largest flat muscle of the abdominal wall.
