Versatest Flashcards
Abdominal cavity location
between the pelvic and thoracic cavity.
How is the abdominal cavity seperated from the thoracic cavity
by the diaphragm
what ventrally bounds the abdominal cavity
the ventral abdominal muscles
How is the abdomen seperated from the pelvis
by the trunk (superior opening of the small pelvis)
what is the peritoneal cavity
an enclosed space within the abdomen
how can the extraperitoneal cavity by divided
abdominal part: the retroperitoneal area or retrositus and a pelvic part: the subperitoneal space.
what forms the physical barrier between the peritoneal cavity and the subperitoneal space in the pelis
the peritoneum
what is the superior wall of the abdominopelvic cavity
the diaphragm
what is the inferior wall of the abdominopelvic cavity
muscles of the pelvic floor
what is the anterolateral wall of the abdominopelvic cavity
muscles of the abdominal wall
how many pairs of oblique muscles are there
3
what is the aponeurosis
a big ass flat tendon that merges in the midline
what do anterior cutaneous nerves do and where are they located
they innervate the skin and are located in the subcutaneous fat tissue
where is the semilunar line and what fuses there
the medial oblique muscles and the aponeurosis
what are the layers of the oblique abdominal muscles from outside to inside
external, internal, transverse
what is the midline of the body called
the linea alba
From superficial to deep what are the layers of the abdominal wall
dermis, epidermis, superficial fascia/camper fascia (subcutaneus fat layer), deep fascia, external oblique, internal oblique, transverse oblique, extraperitoneal fat layer
where and what are the tendinous intersections of the rectus abdominus
interspersed tendineous bands that create the compartments
on which side (ventral or dorsal) is the rectus abdominus crossed by the aponeurosis
both
what is the rectus sheath composition above the umbilicus
it has an anterior sheath and a posterior sheath.
aponeurosis of the externus = anterior
internus = divided between anterior and posterior
transverse = posterior
what is the rectus sheath composition below the umbilicus
only one sheath, the anterior, because of this it is extra thick. however there is still a thin layer posterior that is made of the transversalis facia and peritoneum
what are plicae
umbilical folds
how are plicae formed and where are the structures located that form them
by the parietal peritoneum, they are located between the parietal peritoneum and the transversalis fascia
