Greater and lesser pelvis

Front 3

What is the greater pelvis' function?

Back 3

Provides protection to inferior abdominal viscera

Front 4

What is the lesser pelvis' function?

Back 4

Provides skeletal framework for the pelvic cavity and perineum.

Front 5

What is the perineum?

Back 5

Both the regions that contain the anus and genitalia and a shallow compartment deep to that area.

Front 6

Pelvic girdle

Back 6

Basin-shaped ring of bone connecting the vertebral column to the two femurs.

Front 7

What are the primary functions of the pelvic girdle?

Back 7

Bear weight of the upper body when sitting or standing.
Transfer weight from the axial to the lower appendicular skeleton for standing and walking.
Provide attachment for muscles of posture and locomotion as well as those in the abdominal wall.

Front 8

What are the secondary functions of the pelvic girdle?

Back 8

1. Contain and protect pelvic viscera
2. Support for the abdominopelvic viscera and pregnant uterus
3. Provide attachement for erectile bodies of external gentilia.
4. Provide attachemnt for muscles and membranes that assist in these functions by forming the pelvic floor and filling in the gaps that exist around it.

Front 29

Pevlic Cavity

Back 29

Located between the pelvic inlet superiorly and the pelvic diaphragm inferiorly and contains the terminal parts of the urinary and alimentary systems, internal genital organs and associated vascular and neural structures to supply both the pelvis and lower limbs.

Front 30

Pelvic Floor is formed by what?

Back 30

Bowl-or-funnel-shaped pelvic diaphragm

Front 31

The pelvic diaphragm separates?

Back 31

The pelvic cavity from the perineum and is amde up of the coccygeus and levator ani muscles and fascias covering these muscles.

Front 32

The pelvic diaphragm

Back 32

consists of coccygeus and levator ani muscles and the fascias covering the superior and inferior aspects of these muscles.

Front 33

Coccygus muscles

Back 33

Forms small part of the pelvic diaphragm that supports the pelvic viscera; flexes coccyx

Front 34

Levator Ani

Back 34

Puborectalis
Pubococcygeus
Iliococcygeus
Support the abdominopelvic viscera the puborectalis is particularly involved in maintainging fecal coninence.
