Intro To Hip Flashcards
What are the stability and strength requirements for efficient weightbearing?
Efficient weightbearing requires stability and strength in resting stance, single leg stance, and the ability to handle high forces during movement.
Example sentence: Maintaining stability in single leg stance is crucial for efficient weightbearing.
What are the three types of functional classification of joints?
Diarthroses, amphiarthroses, and synarthroses.
Example sentence: Diarthroses joints allow for free movement.
What are the three types of structural classification of joints?
Fibrous, cartilaginous, and synovial.
Example sentence: Synovial joints are characterized by the presence of synovial fluid.
What is the difference between close packed and open packed positions in joints?
Close packed position is when the joint is most stable, while open packed position is when the joint is least stable.
Example sentence: The close packed position of the knee joint is full extension.
Where does the iliofemoral ligament attach?
The iliofemoral ligament attaches to the lower part of the anterior inferior iliac spine (AllS) and acetabulum to the intertrochanteric line.
Example sentence: The iliofemoral ligament plays a key role in hip joint stability.
Where does the pubofemoral ligament attach?
The pubofemoral ligament attaches from the iliopubic eminence and superior pubic ramus to the lower part of the intertrochanteric line.
Example sentence: The pubofemoral ligament provides support to the hip joint during movement.
Where does the ischiofemoral ligament arise and attach?
The ischiofemoral ligament arises from the body of the ischium to the superior part of the neck and root of the greater trochanter (GT).
Example sentence: The ischiofemoral ligament helps stabilize the hip joint.
What is the function of the acetabular labrum?
The acetabular labrum deepens the acetabulum and is attached to the bony rim and transverse ligament.
Example sentence: The acetabular labrum acts as a cushion and enhances hip joint stability.
What type of movement does a ball and socket joint allow?
Multiaxial movement.
Example sentence: The shoulder joint is a classic example of a ball and socket joint.
What anatomical features contribute to the stability of a ball and socket joint?
Deep socket and labrum.
Example sentence: The hip joint’s deep socket provides added stability during movement.
What is the significance of the angle of the neck of the femur?
It allows muscle leverage and is important for skeletal biomechanics during single-leg stance (SLS).
Example sentence: The angle of the neck of the femur affects the efficiency of hip muscle function.
What is the origin of a muscle?
The origin is where the muscle starts.
Example sentence: The origin of a muscle is usually proximal to its insertion point.
What is the insertion of a muscle?
The insertion is where the muscle ends.
Example sentence: The insertion point of a muscle is typically distal to its origin.
What does innervation refer to in the context of muscles?
Innervation refers to which nerve switches the muscle on.
Example sentence: Proper innervation is essential for muscle contraction.
What are the two basic actions muscles can perform?
Muscles can only get shorter or longer.
Example sentence: Muscle contraction involves the shortening of muscle fibers.
What are the primary hip flexor muscles?
The primary hip flexor muscles are the Iliacus, Psoas Major, Rectus Femoris, Pectineus, and Sartorius.
Example sentence: Strengthening the hip flexor muscles can improve hip mobility.
What are the primary hip extensor muscles?
The primary hip extensor muscles are the Gluteus Maximus, Hamstrings, Biceps Femoris (Long head), Semitendinosus, and Semimembranosus.
Example sentence: Strong hip extensor muscles are essential for activities like running and jumping.
What are the muscles involved in hip abduction?
The muscles involved in hip abduction are the gluteus medius, gluteus minimus, and tensor fascia latae.
Example sentence: Hip abduction exercises can help strengthen the outer hip muscles.
What are the muscles involved in hip adduction?
The muscles involved in hip adduction are the adductor brevis, adductor longus, adductor magnus, gracilis, and pectineus.
Example sentence: Hip adduction movements work the inner thigh muscles.
What are the muscles involved in hip external (lateral) rotation?
The muscles involved in hip external (lateral) rotation are Gluteus maximus, Gluteus medius (posterior part), Piriformis, Obturator internus, Obturator externus, Quadratus femoris, Gemellus inferior, and Gemellus superior.
Example sentence: Hip external rotation exercises can improve hip mobility and flexibility.
Which muscles are responsible for hip internal (medial) rotation?
The muscles responsible for hip internal (medial) rotation are Gluteus medius (anterior part), Gluteus minimus (anterior part), and Tensor fascia latae.
Example sentence: Hip internal rotation is important for activities like walking and climbing stairs.
