1. The genitofemoral nerve is responsible for both the sensory (femoral branch) and
motor portions (genital branch) of the cremasteric reflex, which describes
contraction of the cremasteric muscle when the skin of the superior medial part of
the thigh is touched.
2. It arises by two tendons: one, the anterior or straight, from the anterior inferior iliac
spine; the other, the posterior or reflected, from a groove above the rim of the
acetabulum.
3. adductor magnus consists of two parts. The portion which arises from the
ischiopubic ramus (a small part of the inferior ramus of the pubis, and the inferior
ramus of the ischium) is called the pubofemoral portion, adductor portion, or
adductor minimus, and the portion arising from the tuberosity of the ischium is
called the ischiocondylar portion, or "hamstring portion"
4. Anterior division
In the thigh the anterior division of the femoral nerve gives off anterior cutaneous
and muscular branches.
Anterior cutaneous branches: The anterior cutaneous branches comprise the
following nerves: intermediate femoral cutaneous nerve and medial femoral
cutaneous nerve (Note the lateral femoral cutaneous nerve is a branch from the
lumbar plexus.)
Muscular branches (rami musculares): The nerve to the Pectineus arises immediately
below the inguinal ligament, and passes behind the femoral sheath to enter the
anterior surface of the muscle; it is often duplicated. The nerve to the Sartorius
arises in common with the intermediate cutaneous.
Posterior division
The posterior division- muscular branches supply the four parts of the Quadriceps
5. upper part of the obturator foramen. Here it enters the thigh, through the obturator
canal, and divides into an anterior and a posterior branch, which are separated at
first by some of the fibers of the Obturator externus, and lower down by the
Adductor brevis.
It is, notably, not responsible for the innervation of the obturator internus
6. BICEPS has two heads of origin;
one, the long head, arises from the lower and inner impression on the back part of
the tuberosity of the ischium, by a tendon common to it and the semitendinosus,
and from the lower part of the sacrotuberous ligament;[1]
the other, the short head, arises from the lateral lip of the linea aspera, between the
adductor magnus and vastus lateralis, extending up almost as high as the insertion of
the gluteus maximus; from the lateral prolongation of the linea aspera to within
5 cm. of the lateral condyle; and from the lateral intermuscular septum.
At its insertion the tendon divides into two portions, which embrace the fibular
collateral ligament of the knee-joint.[1]
From the posterior border of the tendon a thin expansion is given off to the fascia of
the leg. The tendon of insertion of this muscle forms the lateral hamstring; the
common fibular (peroneal) nerve descends along its medial border.[1]

"TEA DEPt" for Tibialis anterior, Extensor hallucis longus, Anterior tibial artery, Deep
peroneal nerve, Extensor digitorum longus and Peroneus tertius

12. The fibers originating from the anterior surface of the anterior aponeurosis insert
onto the median septum and the fibers originating from the posterior surface of the
anterior aponeurosis insert onto the posterior aponeurosis.[2][3] The posterior
aponeurosis and median septum join in the lower quarter of the muscle and then
join with the anterior aponeuroses of the gastrocnemius muscles to form the
calcaneal tendon or Achilles tendon and inserts onto the posterior surface of the
calcaneus, or heel bone.
