KIN 3304: CHAPTER 8 QUIZ
Anteriorly, the pelvic bones are joined to form the symphysis pubis, an amphiarthrodial joint.
TRUE
Distally, the patella serves as a major bony landmark to which all four quadriceps muscles attach and ultimately insert on the tibial tuberosity via the patella tendon.
TRUE
Due to the attachment of the iliopsoas and hip adductors, the hip tends to externally rotate more so than internally rotate as active hip flexion increases.
TRUE
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 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.
TRUE
The obturator nerve arises from the anterior division of the lumbar plexus and provides innervation to the hip adductors.
TRUE
The pelvic girdle consists of a right and left pelvic bone joined together posteriorly by the sacrum.
TRUE
The sartorius, the gracilis, and the semitendinosus muscles insert on the anterior medial surface of the tibia just below the condyle.
TRUE
Which of the following pairing represents the truest agonist relationship?
WRONG: RECTUS FEMORIS AND SARTORIUS
Which of the following statements is true about the biceps femoris muscle?
HAS SOME FIBERS THAT ARE NOT INVOLVED KNEE FLEXION
The _____ muscle originates on the inner surface of the ilium and the lower borders of the transverse processes (L1-L5), sides of the bodies of the last thoracic vertebra (T12), lumbar vertebrae (L1-L5), intervertebral fibrocartilages, and base of the sacrum.
ILIOPSOAS
Which of the following is not an action of the pectineus muscle?
ABDUCTION OF THE HIP
In the context of the hip hoint motions, which of the following terms refers to the movement of the femur in the frontal plane medially toward the midline?
ADDUCTION
The medial compartment of the thigh contains the muscles—adductor brevis, the adductor longus, the adductor magnus, the pectineus, and the gracilis—that are primarily responsible for ______.
ADDUCTION OF THE HIP
Agonist muscles during hip flexion include all of the following except the:
ADDUCTOR MAGNUS
The pectineus muscle is located _____ and performs _____ of the hip.
ANTERIOLY; FLEXION
The origin of the rectus femoris muscle is on the:
ANTERIOR INFERIOR ILIAC SPINE & GROOVE ABOVE ACETABULUM
The iliopsoas muscle is located _____ and performs _____ of the hip.
ANTERIORLY; FLEXION
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.
ANTEROLATERAL
The tensor fasciae latae is best stretched in:
COMBINED HIP EXTENSION, ADDUCTION, & EXTERNAL ROTATION WITH KNEE EXTENDED
Which of the following extends the thigh with external rotation?
GLUTEUS MAXIMUS
Which of the following is considered to be an agonist muscle to the tensor fascia latae during hip abduction?
GLUTEUS MEDIUS MUSCLE
Hip flexion refers to the movement of the femur in the frontal plane laterally to the side away from the midline.
FALSE
In addition to flexing and externally rotating the hip, the iliacus is also a lumbar flexor.
FALSE
In the context of the pelvic girdle motions, anterior pelvic rotation refers to the anterior movement of the upper pelvis in which the iliac crest tilts forward in the transverse plane.
FALSE
The acetabular femoral joint, due to its wide range of motion, has relatively weak and loose ligamentous structures which emphasizes the need for stability from the surrounding musculature.
FALSE
The semimembranosus muscle inserts anteromedially on the medial tibial condyle.
FALSE
The structural instability of the acetabular femoral joint makes it susceptible to subluxations and dislocations.
FALSE
The gluteus maximus muscle is stretched in the supine position with full hip flexion to the ipsilateral axilla and then to the contralateral axilla with the knee in _____.
FLEXION
Which of the following muscles is best stretched in a side-lying position by having a partner take the knee into full flexion and simultaneously take the hip into extension?
RECTUS FEMORIS MUSCLE
In the context of the pelvic girdle motions, which of the following statements is true of the right lateral pelvic rotation?
RIGHT PELVIS MOVES INFERIORLY IN RELATION TO THE LEFT PELVIS IN FRONTAL PLANE
Agonist muscles during hip extension include all of the following except the:
SARTORIUS MUSCLE
Which of the following muscles is a two-joint muscle, effective as a hip flexor or as a knee flexor, and is sometimes referred to as the tailor's muscle?
SARTORIUS MUSCLE
Which of the following pairings have the closest anatomical origins to each other?
SEMIMEMBRANOSUS & SEMITENDINOSUS
Which of the following statements is incorrect?
SEMIMEMBRANOSUS IS MORE TENDINOUS THAN THE SEMITENDINOSUS
The insertion of the rectus femoris muscle is on the _____ aspect of the patella and patellar tendon to the tibial tuberosity.
SUPERIOR
