1) Skin, Subcutaneous, Muscle, Fascia, Peritoneum
2) Skin, Subcutaneous, Fascia, Muscle, Peritoneum
3) Skin, Fascia, Subcutaneous, Muscle, Peritoneum
4) Skin, Fascia, Muscle, Subcutaneous, Peritoneum
5) Skin, Fascia, Subcutaneous, Peritoneum, Muscle

Answer 1

The correct order of the abdominal wall layers from the outside in is: Skin, Subcutaneous, Muscle, Fascia, Peritoneum.

Step-by-step explanation:

The layers of the abdominal wall are important both for medical students and for teaching anatomy in order to understand the structures that protect and surround the abdominal cavity. From the outside heading inwards, the correct order is: 1) Skin, 2) Subcutaneous tissue (which includes fat and connective tissue), 3) muscle (comprised of the external oblique, internal oblique, and transversus abdominis), 4) Fascia (transversalis fascia), and finally 5) Peritoneum (starting with the parietal peritoneum, then the peritoneal cavity, and the visceral peritoneum enveloping the organs). Therefore, the correct order presented in the multiple-choice options is option 1: Skin, Subcutaneous, Muscle, Fascia, Peritoneum.
