Muscles of the Abdomen
The abdominal wall encircles the abdominal cavity, providing flexible protection and shielding the internal organs from harm.

Anterolateral Region
The anterolateral region comprises five paired muscles classified into the lateral and anterior...

Muscles of the Pelvic Floor and Perineum
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...
