Pelvis layer 1

 

The pelvis refers to both the soft tissue of the region below the abdomen and abdominal cavity and also to the bones which form the support of the soft tissues, referred to as the lesser pelvis. This lesser or true pelvis has its top boundary as the pelvic brim while the greater or false pelvis is placed above it.

Both the bony and the soft tissues can be approached from the anterior abdominal wall above and also below from the perineum. The perineum carries the external genitalia which includes the clitoris, guarded by prepuce of clitoris, vulva made up of the lips of the vagina which are two in number- labia majora the big lip placed externally and the labia minora the smaller lips placed internally. The region between the labia or vulva is called the vestibule.

The opening into the vagina is the introitus. It is guarded in the virgin by the hymen. The hair bearing area of the perineum is the mons pubis. It merges above with the anterior abdominal wall.

We have seen that this layer contains external genitalia which has clitoris, vulva, labia minora, labia majora, vestibule and hymen.

To recap, this layer contains, mons pubis, external genitalia containing vulva, clitoris, vestibule, labia majora, labia minora and introitus.

 

 

Video learning outcome: Identify mons pubis, external genitalia containing vulva, clitoris, vestibule, labia majora, labia minora, hymen, and introitus on an electronic or real cadaver or on a living/clinical subject.
