S3L2: Functional Anatomy Flashcards
This concept refers to the interlocking ridges and grooves of the bony joint surfaces of the pelvis
Force Closure*
according to ppt, but this is form closure based on https://www.serola.net/the-fallacies-of-the-keystone-form-and-force-closure-concept/#:~:text=Form%20closure%20is%20defined%20as,between%20the%20sacrum%20and%20ilia.
This is achieved through the compressive forces of the muscles, ligaments, and fascia providing passive stability to the SIJ

Modified T/F
A. Pelvic floor muscles support the anus and rectum
B. They also support the intra-abdominal contents
TT
Modified T/F
A. Pelvic diaphragm is a thin, muscular layer of tissue that forms the posterior border of the
abdominopelvic cavity
B. It is composed of a thin, funnel-shaped sling of fascia or muscle
FT
Thin, muscular layer of tissue that forms the inferior border of the
abdominopelvic cavity
T/F
Pelvic Diaphgram extends from the symphysis pubis to the coccyx and from one lateral sidewall to the other
True
Modified T/F
A. Urogenital diaphgram occupies space between the symphysis pubis and ischial tuberosities
B. It stretches across the triangular anterior portion of the pelvic inlet
TF
Stretches across the triangular anterior portion of the pelvic outlet
True or False: The Urogenital Diaphragm is a strong, muscular membrane located external and inferior to the pelvic diaphragm.
True
True or False: Pelvic ligaments are not actual ligaments but are instead a thickening of the intraperitoneal fascia.
False
retroperitoneal fascia
True or False: Pelvic ligaments primarily consist of blood vessels, nerves, and fatty connective tissue rather than collagen fibers.
True
Refers to the continuations of the transversalis fascia of the abdomen
Subserous fascia or endopelvic fascia
Modified T/F
A. Cardinal Ligaments are thin, mesenteric-like double reflection of peritoneum
B. Mackenrodt’s ligaments extend from lateral pelvic sidewalls to the uterus
FF
Both refer to Broad ligaments
T/F
Broad ligaments stretches from lateral pelvic sidewalls to the uterus
True
These ligaments extend from the upper portion of the cervix posteriorly to the 3rd sacral vertebra
Uterosacral ligaments
These ligaments extend from the lateral aspects of the upper part of the cervix and the vagina to the pelvic wall
Cardinal/Mackenrodt’s Ligaments

E) B and C
Modified T/F
A. Internal anal sphicter is an extension of the longitudinal muscles of the rectum
B. External anal sphincter is an extension of the circule muscle layer of the rectum
FF
● Internal Anal Sphincter - Extension of the circular muscle layer of the rectum
● External Anal Sphincter - Extension of the longitudinal muscles of the rectum
T/F
