What is the innervation of the Adductor brevis?
L2-4
Obturator nerve
Adductor brevis is innervated by the obturator nerve, which is derived from the lumbar plexus.
What are the attachments for the adductor brevis
from inferior pubic ramus to distal 2/3 pectineal line and medial lip linea aspera
what are the actions of the adductor brevis
adducts and flex hip
What are the attachments of the Adductor longus?
From pubic crest to medial lip linea aspera
The Adductor longus originates from the pubic crest and attaches to the medial lip of the linea aspera.
What actions does the Adductor longus perform?
Adducts, medially rotates, and flexes hip
The Adductor longus is involved in adduction, medial rotation, and flexion of the hip joint.
What is the innervation of the Adductor magnus (adductor part)?
Obturator nerve
L2-L4
The adductor part of the Adductor magnus is innervated by the obturator nerve.
What are the actions of the Adductor magnus (hamstring part)?
Extends hip
The hamstring part of the Adductor magnus primarily extends the hip joint.
what are the actions of the adductor magnus (adductor)
adducts, flexes hip
what is the innervation of the hamstring part of the adductor magnus hamstring part
sciatic nerve- tibial division
L4-S1
what is the innervation of the of the adductor magnus adductor part
obturator n
L2-L4
What is the innervation of the Gracilis?
Obturator nerve
L2-L4
The Gracilis muscle is innervated by the obturator nerve.
What actions does the Gracilis perform?
Flexes & medially rotates the knee, adducts hip
The Gracilis plays a role in flexing and medially rotating the knee as well as in hip adduction.
what are the attachments of the gracilis m
from the body of the pubis & inferior pubic ramus to the medial surface of tibia, distal to condyle, proximal to insertion of semitendinosus, lateral to insertion of sartorius
What are the attachments of the Pectineus?
From superior pubic ramus to the femur between the lesser trochanter & linea aspera
The Pectineus muscle attaches from the superior pubic ramus to a location on the femur.
What are the actions of the Pectineus?
Adducts, flexes hip
The Pectineus muscle is responsible for adduction and flexion of the hip joint.
what is the innervation of the pectineus
femoral nerve and obturator n (L2-4)
What is the innervation of the Obturator externus?
Obturator nerve
L3-L4
The Obturator externus muscle is innervated by the obturator nerve.
What action does the Obturator externus perform?
Laterally rotates hip
The primary function of the Obturator externus is to laterally rotate the hip joint.
what are the attachments of the obturator externus
from rami of the pubis and ischium; external surface obturator membrane to trochanteric fossa
Innervation of adductor longus
Obturator nerve
L2-L4
