Exam 4 Flashcards
What muscle is best stretched by moving the hip into adduction in front of the opposite extremity and then behind it, and weakness in this muscle can result in a Trendelenburg gait.
Gluteus medius
The gluteus Maximus muscle is stretched in the supine position with full hip flexion to the ipsilateral axilla and then the contralateral axilla with the knee in…
Flexion
When the hip is fully flexed, abducted and externally rotated in combination with full knee flexion and internal rotation which is in the shortest position?
Sartorius
Which muscles are to jointed muscle effective as a hip flexor or as a knee flexor and is sometimes referred to as the tailor’s muscle
Sartorius
Due to the attachment of the iliopsoas and hip adductors, the hip tends to externally, rotate more than internally, rotate as active hip flexion increases
True/Yes
I’m standing on the right foot and attempting to abduct the left hip as much as possible what is happening? [Rpr]
Right pelvic rotation occurs
For the pelvis to rotate in any direction, movement must occur in either the right hip, the left hip, the lumbar spine, or a combination of these locations
True
The Sartorius, gracilis, and the semi tendinosus muscle insert on the anterior medial surface of the tibia just below the condyle
Yes, known as pea anserinus
The medial compartment of the thigh contains the muscles, abductor brevis, the abductor, longest, the abductor Magnus, the pectineus, and the gracilis are responsible for…
Hip adduction
When standing with both feet shoulder with a part and the evenly distributed and attempting to turn and look to the right as far as possible, which of the following is most likely?
Neck rotation, spinal rotation, pelvic rotation
Distally, the patella serves as a major bony landmark to which all four quadricep muscles, attach and ultimately insert on the tibial tuberosity via the patella tendon
Yes/true
What are the actions of the pectineus muscle?
Hip flexion, adduction, external rotation, and assist in pelvic rotation
The hip joint is a ball and socket joint that consists of the head of the femur connecting with the acetabulum of the pelvic girdle, which has its stability enhanced by a labrum
Yes/true
What muscle originates on the inner surface of the ilium and the lower borders of the transverse processes (L1-L5) sides of the body of the last thoracic vertebrae (T12), lumbar vertebrae (L1-L5) intervertebral fibrocartilages and base of the sacrum
Iliopsoas
Are all three gluteal muscles common in the portion of each are antagonistic to the other portion of the same muscle?
No, portions of the gluteal muscles can act antagonistically to each other, depending on the movement
Agonist muscles during hip extension, include all of the following [GSSB]
- gluteus maximus, semimembranosus, semitendinosus, and bicep femoris
- does NOT include sartorius
Which of the following leg muscle pairings represent the truest agonist relationship? [RfSm]
Rectus femoris and semimembranosus
The origin of the rectus femoris muscle is on [Rf-Ai]
Anterior inferior iliac spine and the grove above the acetabulum
Does the femoral nerve arise from the posterior division of the lumbar plexus and innervates the anterior muscles of the thigh?
Yes/True
Which of the following leg muscle pairings have the closest anatomical origins to each other? [SS]
Semimembranosus and semiteninosus
In the context of the hip joint motions, what term refers to the movement of the femur in the frontal plane mediately towards the midline?
Hip adduction
Agonist muscles during hip flexion include… [AdmSSBfGm]
Adductor magnus, semitendinosus, semimembranosus, bicep femoris, gluteus maximus
The insertion of the tensor fasciae latae muscle is one-fourth of the way down the thigh into the iliotibial tract which in turn inserts onto Gerdy’s tubercle of the_____tibial condyle [AL]
Anterior lateral
