Anterior Medial Thigh Flashcards
Obturator Externus M. Attachments
External margin of obturator foramen
Trochanteric fossa
Sartorius M. Origin
ASIS
longest muscle, and most superficial anterior muscle
Adductor Longus M. Innervation
Obturator N. (L2-L4)
What spinal roots supply the Common Fibular Nerve?
L4-S2
Sartorius M. Innervation
Femoral N.
Adductor Longus M. Attachments
Body of pubis
Middle 1/3 of linea aspera
What nerve function does the Calcaneal Tendon reflex test for?
S1 and S2 nerve roots (also known as ankle-jerk reflex)
Adductor Brevis M. Insertion
Obturator N.
What three tendons make up the Pes anserinus?
- Sartorius tendon
- Gracilis tendon
- Semiteninosus tendon
(Common insertion for three muscles innervated by 3 diff nerves)
What spinal roots supply the Obturator N?
L2 - L4
What can cause Osgood-Schlatter Disease?
Repeated stress from a lot of jumping, running, and bending (soccer, basketball, volleyball, ballet)
Stress pulls on the tendon that connects the kneecap to the shinbone. Eventually it will pull away
What tendon is tested during the Patellar reflex?
Patellar tendon
Quadriceps Femoris M. Origin
Rectus femoris: ASIS
Vasti: shaft of femur
What nerve function does the Patellar Reflex test?
Functions of the femoral N. and spinal chord segments L2-L4
What are the two parts of the Adductor Magnus M.?
- Adductor portion
- Hamstring portion
*Largest Adductor muscle!
What is the overall function of the MEDIAL thigh compartment?
What nerve is responsible?
Adduction
Obturator N.
Sartorius M. Insertion
Pes Anerinus
Adductor Brevis M. Attachment
Pubis body & inferior ramus
Proximal linea aspera
(deep to pectineus and adductor longus)
What happens during a groin pull?
Strain, stretching, tearing of adductor/flexor muscles
proximal side of muscles are affected!
What is the overall function of the ANTERIOR thigh compartment?
What nerve is responsible?
Extension
Femoral N
Iliopsoas M. Innervation
Iliacus = Femoral N
Psoas major = L1-L3 ventral rami
Psoas minor = L1 - L2 ventral rami
Gracilis M. Innervation
