Anterior and Medial Thigh Flashcards
Chondromalacia patella
Lateral shift of the patella associated with irritation and pain. Treatment via IT band and strengthening vastus medialis
Patellar Reflex
Tests the function of the femoral nerve and spinal cord segments L2-L4. The absence or decrease of this reflex is known as Westphal’s sign
Absence of the patellar reflex is known as?
Westphals sign
Calcaneal Tendon Reflex
Tests the S1 and S2 nerve roots. The foot plantarflexes during this reflex. If the nerve root is cut or compressed the ankle reflex is virtually absent
The iliopsoas muscle is made up of which two muscles?
The psoas major and iliacus muscles
Iliopsoas action
● Act conjointly in flexing and stabilizing thing at hip joint.
● Psoas major also postural muscle that helps control deviation of the trunk.

Bursa
Cyst within the connective tissue that allows muscle to slide
iliopectineal bursa
Bursa used to help move the iliopsoas musculature
Sartorius m. action

Hiltons Law
A joint is innervated by the very same nerves that supply the muscles that move the joint and supply the skin over it.
