The anterior thigh contains what?

"groin muscle", a thigh flexor, and the quadriceps femoris, a compound muscle that primarily gives the anterior thigh its overall shape.

Explain femoral triangle

neurovascular elements pass through this space in the anterior thigh.

NAVEL right leg- femoral (nerve, artery, vein, empty space, lymph vessels).

LEVAN left leg

The demarcation between the anterior thigh and anterior abdominal wall is the...

Inguinal Ligament

It forms the base of the inguinal canal through which an indirect inguinal hernia may develop.

The inguinal (crural) ligament runs from the anterior superior iliac spine of the ilium to the pubic tubercle of the pubic bone.

It is formed by the external abdominal oblique aponeurosis and is continuous with the fascia lata of the thigh

The muscles of the anterior thigh are innervated by...

The femoral nerve (from the lumbar plexus), it ends by dividing into several motor branches just posterior to the inguinal ligament.

What is the one muscle that is not served by the femoral nerve branches, in the anterior compartment of the thigh?

Tensor Fascia Latae, which is developmentally related to the gluteal muscles and innervated by the superior gluteal nerve.

Arterial blood to the anterior thigh is provided from two principle sources...

the femoral artery (which is a continuation of the external iliac artery), and the obturator artery, a branch of the internal iliac artery.

hint: you can follow the femoral artery all the way down to your toes, but with the name changing in the adductor hiatus to the popliteal artery. Going the opposite way for the vein it would change from the popliteal vein to the femoral vein.

Which of the following is not considered a major branch off of the femoral artery?

A. Superficial pudendal arteries
B. Deep external pudendal arteries
C. Superficial circumflex iliac artery
D. Deep circumflex iliac artery

D. Deep circumflex iliac artery

The major branch of the femoral artery is...

The profunda femoris artery.

The profunda femoris artery supplies blood to what muscles...

some of the anterior thigh muscles and most of the meidal thigh. It branches off from the femoral nerve and is closer to the femur.

muscles of the anterior thigh include...

iliopsoas muscle

quadriceps femoris (rectus femoris, vastus lateralis, vastus intermedius, vastus medialis)

sartorius

and the tensor fasciae latae muscle

The iliopsoas muscle consists of two muscles...

The psoas major muscle and the iliacus muscle.

(The psoas minor is a slender, inconstant muscle that blends with the major but, unlike the psoas major m., attaches to the pubic bone (iliopubic eminence) via a long flat tendon.

What are the major extensors of the leg...

The vasti plus the rectus femoris form the quadriceps femoris muscle.

What is the common tendon of insertion of the quadriceps?

Rectus femoris tendon, which envelopes the patella and continues on to attach to the tibial tuberosity. However, the portion extending from the patella to the tibial tuberosity is called the patellar ligament.

FYI: The retus femoris is an antagonist to the hamstrings.

When the patellar ligament is tapped (knee jerk reflex), what muscular reflex at the lumbar cord is it testing?

L4 If response is slow, it may indicate a defect in nerve conduction.

Prepatellar bursa is?

Bursae around the knee can become inflammed with acute overuse and/or enlarged with chronic overuse. (superficial to the patellar)

What is the small muscle continuous (or derived from) the vastus intermedius?

The articularis genus muscle. The fibers originate low on the anterior femur and attach directly to the suprapatellar bursa of the knee. This muscle may prevent soft tissue from catching or being pinched as the knee joint is brought into extension.

The tensor fasciae latae muscle is innervated by?

The superior gluteal nerve, although having actions and placement similar to the anterior thigh muscles.

The sartorius muscle, which was known to be the crossed leg style of sitting as tailors stitched and hemmed refelcts the movements by the sartorius, which is what?

Thigh flexion, abduction, and lateral rotation with leg flexion.

AKA: the sex muscle!!

The principal nerve for the medial thigh is the??

obturator nerve, derived from the lumbar plexus. Typically the nerve divides into an anterior and posterior branch. The tibial portion of the sciatic nerve serves some of the adductor magnus.

What muscle is innervated by the femoral nerve, but sometimes the obturator nerve as well?

pectineus muscle

The six muscles of the medial thigh include?

Gracilis muscle, adductor magnus muscle, adductor longus muscle, adductor brevis muscle, pectineus muscle, obtruator externus muscle.

What is the main vasuclar supply of the medial thigh?

Profunda femoris (deep artery of the thigh) is the principal source of blood to the majority. Both medial and femoral circumflex arteries typically arise from the profunda femoris artery and serves the lateral thigh and the region around the hip joint.

Which artery supplies four large perforating branches to the posterior thigh as well as to the medial thigh?

The profunda femoris, whereas the obturator artery, which is a branch from the internal iliac artery, serves structures in the more superior aspect of the medial thigh.
