Abdominal Regions and Quadrants01:19

Abdominal Regions and Quadrants

18.6K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...

Development of the Sexual Organs in the Embryo and Fetus01:15

Development of the Sexual Organs in the Embryo and Fetus

4.2K
Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the...

The Ratio of X Chromosome to Autosomes02:45

The Ratio of X Chromosome to Autosomes

9.9K
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.  
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...

Veins of the Abdomen and Pelvis01:18

Veins of the Abdomen and Pelvis

1.9K
The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

The Y Chromosome Determines Maleness02:19

The Y Chromosome Determines Maleness

8.6K
The Y chromosome is a sex chromosome found in several vertebrates and mammals, including humans. In addition to 22 pairs of autosomes, the human males have one X chromosome and one Y chromosome. In these organisms, the presence or absence of the Y chromosome determines the development of male traits.
Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size....

Blood Supply to the Digestive System01:16

Blood Supply to the Digestive System

5.8K
Splanchnic circulation refers to the network of blood vessels that supply and drain blood from the abdominal organs involved in digestion, including the stomach, liver, pancreas, intestines, and spleen. This circulation delivers essential nutrients and oxygen while removing waste products from these organs.
Blood Supply to the Digestive System: The splanchnic circulation involves three main arteries: the celiac artery (also known as the celiac trunk) and the superior and inferior mesenteric...

Summary
This summary is machine-generated.

Surgeons may find splenic flexure mobilization harder in men due to anatomical differences. This study found the splenic flexure is higher and further from the midline in males compared to females.

Area of Science:

  • Colorectal Surgery
  • Surgical Anatomy
  • Medical Imaging

Background:

  • Surgeons often report increased difficulty mobilizing the splenic flexure in male patients.
  • No prior scientific studies have quantitatively investigated anatomical differences in splenic flexure position between sexes.

Purpose of the Study:

  • To quantitatively assess anatomical differences in splenic flexure position between male and female patients.
  • To investigate if computed tomography (CT) can identify significant positional variations.

Main Methods:

  • Analysis of portal venous phase CT scans from 100 patients undergoing preoperative assessment for colorectal malignancy.
  • Comparison of splenic flexure position using two metrics: vertebral level height and distance from the midline.

Main Results:

  • The splenic flexure was significantly higher in men (mean vertebral level 8.88) compared to women (mean vertebral level 11.36).
  • The splenic flexure was also significantly further from the midline in men (mean 160.8mm) than in women (mean 138.2mm).
  • These differences were statistically significant (p<0.0001).

Conclusions:

  • The splenic flexure exhibits a higher and more lateral position in male patients compared to female patients.
  • This anatomical variation may explain the anecdotal surgical observation of increased difficulty in splenic flexure mobilization in men.
  • Findings provide a quantitative basis for understanding sex-based anatomical differences in colorectal surgery.
