Q

. What bones make up the hip joint? What types of actions are possible at the hip joint? What muscles carry out these actions? What is the innervation of these muscles?

A

bones involved: Os coxae- acetabulum

Femur: head and neck

Actions: adduction, abduction, flexion, extension, lateral and medial rotation

Adduction: adductor group, lateral rotation is lateral rotators and hamstring muscles, abductors and medial rotators are the gluteal group (externally), and the illiopsoas group (internally)

Innervation: femoral, obturator and superior gluteal n

59
Q

What is the blood supply of the hip joint?

A

Medial and lateral circumflex femoral aa

artery to the head of the femur (branch of obturator a)

inferior gluteal a

60
Q

What nerves supply sensory innervaiton to hip joint?

A

Femoral, obturator and superior gluteal n

61
Q

What types of actions are possible at the knee joint? What muscles carry out these actions? What is the innervation of these muscles?

A

Flexion, extension, small amount (+- degrees of rotation)

Hamstring muscles flex knee, quadricep muscles extend knee, sartorious medially rotates, popliteus laterally rotates

Innervation: tibial and common fibular n

62
Q

What is the blood supply to the knee

A

genicular branches of femoral artery, poplieteal and tibial arteries forming the genicular anastomosis
