Anterior abdominal wall:the points

This shows surface anatomy of
some lines on the anterior abdominal
wall like:
1-McBurney's point is halfway between
the umbilicus and the ASIS ( anterior
superior illiac spine ) and it is a common
location where surgeons use for an
incision to remove the appendix.
2-The linea alba is a fibrous structure
that runs down the midline of the
abdomen and seperates the left and
right rectus abdominus muscles.
3-The arcuate line demarcates the lower
limit of the posterior layer of the rectus
sheath.
4-The inguinal ligament is a band
running from the pubic tubercle to the
anterior superior iliac spine, its anatomy
is very important for operating on
hernia patients.
This ligament passes between two bony
points of the hip bone, the anterior
superior iliac spine laterally and the
pubic tubercle medially. It has an
expanded medial end, the lacunar
ligament.
The inguinal ligament is the thickened,
recurved free inferior border of the
external oblique muscle. It forms the
floor of the inguinal canal along which
passes the spermatic cord in the male or
the round ligament of the uterus in the
female.
5-The linea semilunaris is a curved
tendinous line placed one on either side
of the rectus abdominus and
corresponds with the lateral
