Pelvis and Hip

Bones of the pelvic girdle

Ilium, ischium, pubis

Articulations of the pelvic girdle

Sacroiliac and the symphysis

Is the pelvic girdle a complete or incomplete girdle?

Complete girdle

The pelvic girdle is dependent on the ________________ joints for its movements

Lumbosacral and hip joints

An analysis of the movements of the pelvic girdle must always be stated in terms of both ________ and __________action

Spinal and hip

Movements of the pelvis

Anterior, posterior, lateral tilt, and rotation

The lateral tilt is named in terms of the side of the pelvis that is ________________

Moved downward

The rotation of the pelvis is named in terms of the direction which the _____________ of the pelvis turns

Front

True or False: All of the muscles that attach to the pelvic bones or to the sacrum serve to either initiate or to control pelvic movements

True

Where are primary movements of the pelvis initiated?

The pelvis

Are most movements of the pelvic girdle primary or secondary?

Secondary

If the pelvic girdle depends on joints of the lower spine and the hip for its movement, then its movement is ________________ to that of the spine or thighs

Secondary

If movement is initiated in the pelvic girdle itself, with the spine and thighs cooperating with it, the movement of the pelvis is considered _________________

Primary

When the primary movement of the pelvis is a forward tilt, what are the secondary movements of the spinal and hip joints?

Spinal: hyperextension
Hip: Slight flexion

When the primary movement of the pelvis is a backward tilt, what are the secondary movements of the spinal and hip joints?

Spinal: Slight flexion
Hip: Complete extension

When the primary movement of the pelvis is a lateral tilt left, what are the secondary movements of the spinal and hip joints?

Spinal: Slight lateral flexion right
Hip: R: Slight adduction / L: Slight abduction

When the primary movement of the pelvis is rotation left, what are the secondary movements of the spinal and hip joints?

Spinal: Rotation right
Hip: R: Slight external rotation / L: Slight internal rotation

Which muscles are responsible for forward tilt of the pelvis?

Hip flexors and lumbosacral spinal extensors

Which muscles are responsible for backward tilt of the pelvis?

Hip extensors and lumbosacral spinal flexors

Which muscles are responsible for right lateral tilt of the pelvis?

Left lateral lumbosacral flexors, right hip abductors, and left hip adductors

Which muscles are responsible for right rotation of the pelvis?

Left lumbosacral rotators, left hip external rotators, and right hip internal rotators

As the spine undergoes flexion, what is the secondary movement of the pelvis?

Backward tilt

As the spine undergoes hyperextension, what is the secondary movement of the pelvis?

Forward tilt

As the spine undergoes lateral flexion left, what is the secondary movement of the pelvis?

Lateral tilt left

As the spine undergoes rotation left, what is the secondary movement of the pelvis?

Rotation left

The hip joint is classified as what type of joint?

Ball and socket

The acetabulum found on the pelvis is similar to the _________________ on the scapula

Glenoid fossa

_________________ adds depth to the hip joint and serves to cushion against impact of the femoral head

Acetabular labrum

The head of the femur and the acetabulum are both lined with ______________

Hyaline cartilage

A strong flat band that bridges the acetabular notch and completes the acetabular ring

Transverse acetabular ligament

"Ties" head of femur to lower part of acetabulum and provides reinforcement from within

Teres femoris ligament

Extraordinarily strong band that checks extension and rotation of the hip

Iliofemoral ligament

Ligament that prevents excessive abduction

Pubofemoral ligament

Strong triangular ligament that limits rotation and adduction in the flexed position

Ischiofemoral ligament

Movements of the femur at the hip joint

Flexion, extension, hyperextension, abduction, adduction, medial and lateral rotation, diagonal abduction and adduction, and circumduction
