Lower Extremity: ANT/MED Thigh; Glut Flashcards
What structures are contained within the superficial fascia?
- Deep sweat glands
- Lymph nodes
- Cutaneous nerves/vessels
Describe the attachments And form of the deep fascia of the thigh.
- Encloses thigh like a trouser leg
- Upper end attaches to pelvis and inguinal ligament
- lateral aspect thickens to form
IT Tract - encloses tensor fascia lactate and gluteus Maximus
What is the saphenous opening?
A gap in the deep fascia in front of the thigh just below inguinal ligament
Filled with loose CT called cribiform fascia
What are the intermuscular septa in the thigh?
- Medial IM
- Posterior IM
- Lateral IM
What are the two groups of inguinal lymph nodes? What do they drain?
Medial: Ant abdominal wall, lower part of anal canal. External genitalia
Lateral: Buttocks and back
What is the main venous drainage of the thigh? Describe its path, any landmarks, etc
Great saphenous vein
- Formed by dorsal venous arch of foot
- Ascends medially and ascends anteriorly to the medial malleolus at ankle and posteriorly to medial epicondyle of knee
- terminates and drains into femoral vein inferiorly to inguinal ligament
- Used in coronary artery bypass
What are the muscles of the anterior thigh?
Sartorial
Quads:
- Rectus Femoris
- 3 Vastus mms
What are the muscles of the anterior hip?
- Iliopsoas
- Quadratus Lamborum
What are the attachments and actions of sartorius?
ASIS —> Medial surface of tibia
Flexes, abducts, and lateral rotates thigh; flexes leg
What is the innervation and blood supple of Sartorius?
Femoral Nerve
Latearl Femoral Circumflex; Sapheous artery
What are the attachments and actions of rectus femoris?
Straight head: AIIS, Relflected head: above superior rim of acetabulum —> Patella and tibial tuberosity via patellar ligament
Extends leg; flexes thigh
What are attachments and actions of vastus intermedius?
Anterior and Lateral surface of femur —> Patella
Extends leg
What are attachment and actions of Vastus lateralis?
Lateral IM septum, Lateral lip of linea aspera, and gluteal tuberosity —> Patella and medial patellar retinaculum
Extends leg
What area attachments and actions of vastus medialis?
Medial IM septum, medial lip of linea aspera —> PAtealla and medial patellar retinaculum
Extends leg
What is innervation and blood supply for the Quads?
Femoral Nerve
Lateral femoral circumflex
** perforating branches of deep femoral supplies some of vastus lateralis
What muscles make up the posterior and lateral hip?
- Glut max/med
- Piriformis
What are the attachments and actions of the Tensor fascia latte?
Iliac crest, ASIS —> IT Tract
Flexes thigh, abduct thigh, medial rotation
What is the innervation of the Tensor fascia Latae?
Superior Gluteal nerve
What are attachments and actions of iliopsoas?
Side of T12-L5 Vert, Iliac crest/fossa —> Lesser trochanter of femur, pectineal line
Flexes thigh
What is the innervation of the iliopsoas?
Femoral nerve
What are the Cutaneous innervation of the Leg?
Latearl cut nerv eof thigh -> Latearl aspect of thigh
Intrapatellar and medial cutaneous branches of saphenous nerve -> Medial aspect of lower leg and knee joint
Anterior cutaneous branch femoral nerve —> Anterior thigh
Obturator cutaneous branch —> Posteromedial aspect of thigh
What compartment and muscles are innervates by Obturator nerve?
MEdial compartment
- Gracilis
- Adductor Longus
- Adductor Brevis
- Adductor Magnus
- Pectineus
What are attachments and actions of gracilis?
Pubic symphysis, inf pubic Ramos —> Medial surface of tibia via pes anserinus
Adducts thigh, flexes and medial rotates thigh, flexes leg
What are attachments and actions of adductor longus?
Medial portion of sup pubic ramus —> Linea aspera
Adducts, flexes, medially rotates femur
