Study Notes

Pelvic Girdle

The pelvic girdle, also known as the hip girdle, is a ring-like structure formed by the two hip bones (coxal bones) and the sacrum.
The ilium, ischium, and pubis are the three bones that fuse to form each coxal bone.
The pelvic girdle functions to connect the lower limbs to the axial skeleton.
It supports the weight of the body and transmits forces from the lower limbs to the axial skeleton.
The sacroiliac joint is a synovial joint that connects the sacrum to the ilium.

Pelvic Muscles - Anterior Group

The anterior pelvic floor muscles include the levator ani and coccygeus muscles.
The levator ani muscle group is responsible for functions like continence and supporting the pelvic viscera.
These muscles play a crucial role in pelvic floor stability.
The iliococcygeus, pubococcygeus, and puborectalis are three individual muscles that make up the levator ani.
The coccygeus muscle forms a triangle shape and acts synergistically with the levator ani muscles to support the pelvic floor.
Muscles in this group are crucial for proper urinary and fecal continence.

Pelvic Muscles - Posterior Group

The posterior pelvic floor muscles are involved in actions that influence pelvic organs.
The ischiococcygeus and coccygeus muscles aid in supporting the pelvic organs.
These posterior muscles are key components of pelvic support.
The muscles surrounding the pelvic cavity, collectively known as the pelvic diaphragm, play a role in various pelvic functions including support and stability.

Muscles of the Gluteal Region

Gluteus maximus, medius, and minimus muscles are important for hip extension, abduction, and internal/external rotation.
Gluteus maximus, the most prominent muscle, is responsible for hip extension.
Gluteus medius and minimus are crucial for hip abduction, and stability at the hip joint.
These muscles are critical for maintaining posture and mobility in the pelvis.

Muscles Involved in Hip Flexion

Key muscles responsible for hip flexion include the iliopsoas group (iliacus and psoas major muscles).
Iliacus and psoas major muscles are located anterior to the pelvic cavity.
These muscles are essential to bring the femur closer to the torso or trunk.

Muscles Involved in Hip Adduction

The adductor muscles group—including adductor longus, brevis, magnus, and gracilis—are crucial for hip adduction.
These powerful muscles help bring the thighs together.
The adductor group aids in maintaining hip stability and is involved in movement and support.

Muscles Involved in Hip Rotation

Muscles influencing hip rotation include the external rotators (piriformis, gemellus superior and inferior, obturator internus and externus, and quadratus femoris).
Muscles for internal rotation are also present.
Understanding these rotator muscles is vital for comprehending how different movements at the hip can occur and how these actions are supported by different muscles.

Innervation and Blood Supply

Specific nerves and arteries supply blood flow and innervation to the pelvic muscles.
Understanding blood flow and nerve supply is important for comprehending how these muscles function.
Injuries to the nerves and vessels that supply them can cause dysfunction in the pelvic muscles.

Pelvic Floor Dysfunction

Pelvic floor dysfunction encompasses various conditions impacting the pelvic floor muscles, nerves, and support structures.
Common issues—including incontinence, prolapse, and chronic pelvic pain—involve weak, tight, or damaged pelvic muscles or nerves.
These conditions can affect bowel and bladder function and sexual health.
Proper treatment and management require an understanding of the pelvic floor anatomy.

Clinical Significance

Pelvic muscle anatomy is relevant in various medical diagnoses and treatments.
Surgeons, physical therapists, and other medical professionals use this knowledge to approach various conditions and injuries.
Knowledge of pelvic muscle anatomy is crucial for correct diagnosis and treatment of pelvic floor dysfunctions.
This knowledge aids in surgical and rehabilitation approaches.
