muskuloskeletal anatomy Flashcards
Where is the sacrum and symphysis pubis on this photo?
Sacrum – Posterior
Symphysis Pubis – Anterior
what is another name for linea terminalis and what is it?
iliopectineal line
imaginary line from sacral promontory to symphsis pubis separating the true pelvis (lesser/minor pelvis) from the false pelvis (greater/major pelvis)
What does the true pelvis contain?
Internal reproductive organs: Uterus, Vagina, Fallopian tubes, and Ovaries
Bladder & pelvic ureters
Distal rectum & anus
What musculature is on the anterior abdominal wall b/t the rectus abdominis muscles?
linea alba
Where are the psoas and iliospas muscles ?
–
From lower thoracic & lumbar vertebra
–
Course lateral & anterior to insert into hip joint
–
Hypoechoic outer and hyperechoic inner (femoral nerve sheath)
Identify the obturator internus, piriformis and levator ani muscles of the pelvic diaphragm
Obturator Internus –Lateral, anterior
Piriformis – Lateral, posterior & superior
Levator ani / makes up pelvic diaphragm or floor
What 3 muscles make up the pelvic floor of the levator ani?
Pubococcygeus
Puborectalis
Iliococcygeus
looks like a hammock between symphysis & sacrum
what are ligaments?
what do they connect to?
Bands of fibrous connective tissue that provide support and attach to various tissues
Ligaments connect to: Bones, Muscles and Cartilages
What is the Wing-like double fold of peritoneum that connects uterus to pelvic side walls and contains:
Fallopian tubes, Blood vessels, Nerves, fat
the broad ligament
What parts are continuous with the broad ligament?
Mesovarium, Mesosalpinx and Mesometrium
identify the ovarian, infundibulopelvic, round, sacro-uterine and carnal (Mackenrodt’s) Ligaments
Ovarian Ligament - Connects ovary to uterus
Infundibulopelvic (suspensory) Ligament - Lateral of broad ligament & attaches to the pelvic side wall, contains ovarian blood vessels
Round Ligament - Fundus to anterior pelvic side wall
Where does the pelvic blood supply come from?
internal and external iliac arteries and uterine arteries
Where is this view taken from?
above
What are the order of arterieal vessels of the reproductive system from medial to lateral?
Endometrial arterioles – Spiral (reach surface of endo), Straight (stay deeper)
Myometrial arteries - Radial, Arcuate
Uterine arteries
Internal iliac arteries
Where does the ovarian blood supply come from?
Lt/Rt ovarian and uterine veins and arteries or vessels.
what are the 2 peritoneal reflections in the pelvis called?
viseicouterine pouch or anterior cul-de-sac
rectouterine pouch, pouch of douglas or posterior cul-de-sac
