Lec.13: Fascia of the Pelvis and Lower Extremity Flashcards
superficial fascia subdivided into what 2 layers
superficial layer: Camper’s “fatty” layer
deeper layer: Scarpa’s “membranous” layer
memory queue for the two layers of the superficial fascia
Scarpa’s go deep into backcountry, Camper’s should not go deep
the camper’s layer of the superficial fascia provides ___ over the pubic symphysis
protection
deep membranous layer of superficial fascia of abdomen blends with what (2)
-superficial fascia of the back and thorax
-deep fascia of thigh below the inguinal ligament
which fascial layer is deep to the deep membranous layer (Scarpa’s fascia)
Deep fascia of the EXT oblique
another name for the Deep fascia
Investing fascia
what structure attaches to the sternum, xiphoid process and costal cartilage superiorly and the pubic crest and tubercle inferiorly
rectus sheath
what does rectus mean
straight
what fascia structure surrounds the rectus abdominis and blends laterally with the aponeuroses of the other 3 abdominal mms
rectus sheath
structure that attaches SUP LAT on the pubic tubercles and extends to the ASIS
inguinal ligament
the fascia of which layer and region is generally thicker in females than males
superficial fascia of the gluteal region
which fascial layer of the abdomen is continuous with the visceral pelvic fascia
investing/deep fascia
The aponeurotic extensions of internal oblique mm split to form the anterior & posterior layers of the ___ ___
rectus sheath
Fibres crossing midline between two heads of rectus abdominis form the ___ ___
linea alba
the arcuate line of the rectus sheath is ~ ___ above ASIS
2cm
INF to arcuate line of RA, the rectus sheath does what?
passes directly anterior to rectus abdominis (RA).
why is there an inherent weak zone in the lower abdominal fascia
b/c INF to the arcuate line of RA the rectus sheath does no envelope the RA posteriorly. The only fascia POST to RA in the lower abdomen is the transversalis fascia
continuous fascial layer with the deep fascia of the thigh (fascia lata) and splits to enclose gluteus maximus
deep fascia of gluteal region
the deep fascia of the gluteal region and the fascia lata is ___ to glute MED and inserts on the tibia at ___ ___
superficial, Gerdy’s tubercle
the superficial fascia of the thigh is an extension of the ___ fascia from the ___ ___
superficial, ANT abdomen
a gap in the fascia lata of thigh just inferior to inguinal ligament for great saphenous vein & superficial lymph vessels to re-enter pelvis
saphenous opening/fossa ovalis
an INF extension of the fascia of the abdominal wall into the thigh

contents of femoral sheath form LAT to MED
-femoral artery
-femoral vein
