General Arrangement of the Abdominal Viscera Flashcards
Is a large organ that occupies the upper part of the abdominal cavity it lies almost entirely under the cover of the ribs and causal cartilages and extends across the epigastric region.
Liver
Is a pear shaped sac that is adherent to the under surface of the right lobe of the liver it’s blind and or fundus projects below the inferior border of the liver.
Gallbladder
Is a tubular structure that joins the pharynx to the stomach. It pierces the diaphragm slightly to the left of the midline and after a short course of about 0.5 in (1.25 cm) enter systemic on its right side. It is deeply placed lying behind the left lobe of the liver.
Esophagus
Is a dilated part of the alimentary canal between the esophagus and the small intestine it occupies left upper quadrant, epigastric, and umbilical regions, and much of it lies undercover of the ribs it’s long axis passes downward and forward to the right and then backward and slightly upward.
Stomach
Is divided into three regions do duodenum, jejunum, and ilium
Small intestine
Is the first part of the small intestine and most of it is deeply placed on the posterior abdominal wall it is situated in the epigastric and umbilical regions it is a C-shaped tube that extends from the stomach around the head of the pancreas to join the jejunum.
Duodenum
Together measures about 20 ft 6 m long.
Jejunum and ileum
True or false.
The judgment begins at the duodenogenal function and the ilium ends at the iliosical junction.
True
Occupy the upper left part of the abdominal cavity whereas the ilium tends to occupy the lower right of the abdominal cavity and the pelvic cavity.
The coils of jejunum
Is divided into the cecum, appendix, ascending colon, transverse colon, descending colon sigmoid colon, rectum, and anal canal.
It arches around and encloses the coils of the small intestine and tends to be more fixed than the small intestine.
Large intestine
Is a blind ended sac that projects downward and the right iliac region below the iliocecal junction.
Cecum
Is a worm shaped tube that arises from its medial side.
Appendix
Extents upward from the cecum to the interior surface of the right lobe of the liver occupying the right lower and upper quadrants.
Ascending colon
From the ascending colon, on reaching the liver, it bends to the left forming the?
Right colic flexure
Crosses the abdomen and the umbilical region from the right colic fletcher to the left colic flexure.
Transverse colon
It forms a white u shaped curve. In erect position, the lower part of the ume extend down in the pelvis.
Transverse colon
The transverse colon, on reaching the region of the spleen bends downward forming the?
Left colic flexure
Extends from the left colic fletcher to the pelvis below. It occupies the left upper and lower quadrants.
Descending colon
Begins at the pelvic implant where it is a continuation of the descending colon. It hangs down into the pelvic cavity in the form of a loop. It joins the rectum in front of the sacrum.
Sigmoid colon
- Occupies the posterior part of the pelvic cavity.
- It is continuous above with the sigmoid colon and the descends in front of the sacrum to leave the pelvis by piercing the pelvic floor.
- Here, it becomes continuous with the anal canal in the perineum.
Rectum
- Occupies the posterior part of the pelvic cavity.
- It is continuous above with the sigmoid colon and the descends in front of the sacrum to leave the pelvis by piercing the pelvic floor.
- Here, it becomes continuous with the anal canal in the perineum.
Rectum
- Is a soft lamulated organ that stretches obliquely across the posterior abdominal wall and the epigastric region.
- It is situated behind the stomach and extends from the duodenum to the spleen
Pancreas
- Is a soft mass of lymphatic tissue that occupies the left upper part of the abdomen between the stomach and the diaphragm.
- it lies along the long axis of the 10th left rib.
Spleen
Are two reddish brown organs situated high up on the posterior abdominal wall, on one each side of the vertebral column.
Kidneys
What is the difference between the left and the right kidney?
The left kidney lies slightly higher than the right because the left lobe of the liver is smaller than the right
Each kidney gives rise to a ________that runs vertically downward on the psoas muscle.
Ureter
Are two yellowish organs that lie on the upper poles of the kidneys on the posterior abdominal wall.
Suprarenal glands
