Anterior Pelvis/ Gluteals/ Deep Hip Rotators

The anterior pelvis muscles include the Psoas and Iliacus, which are responsible for hip flexion and stability. Rectus abdominis, Sartorius, and Gluteus medius are not classified as anterior pelvis muscles.

The gluteal group consists of the Gluteus Maximus, Gluteus Medius, Gluteus Minimus, and Tensor Fascia Latae muscles which are primarily responsible for hip movement and stabilization.

The Deep Hip Rotators are a group of muscles responsible for external rotation of the hip joint. Gluteus Maximus, Tensor Fasciae Latae, and Sartorius are not part of this specific group of muscles.

The PSOAS muscle is associated with the lumbar plexus nerves, has attachments at T12-L5 and the lesser trochanter, and performs actions such as thigh flexion, lateral rotation, pelvic posterior tilt, trunk flexion, and pelvic anterior tilt.

The gluteus maximus muscle is primarily innervated by the Inferior Gluteal nerve, originating from the spinal levels L5, S1, and S2. The other options do not supply the gluteus maximus muscle.

The gluteus medius is responsible for various movements at the hip joint and pelvis, including abduction, flexion, medial rotation, extension, lateral rotation, depression, posterior tilt, anterior tilt, and contralateral rotation.

The correct answer provides the specific nerves, attachments, and actions associated with the Tensor Fascia Latae muscle. The three incorrect answers provide alternative nerves, attachments, and actions that do not correspond to the actual characteristics of the muscle, leading to confusion and potential misinformation.

The main function of the piriformis muscle is related to the nerve aspect, with the primary function being its connection to the Lumbrosacral Plexus (L5, S1, S2). Therefore, options focusing on attachments or origin would be incorrect.

The Superior Gemellus muscle is innervated by the Lumbrosacral Plexus consisting of nerves from the fifth lumbar and first sacral spinal segments. The Femoral nerve, Sciatic nerve, and Obturator nerve do not supply the Superior Gemellus muscle.

The correct nerve for obturator internus is the Lumbrosacral Plexus (L5, S1), not the Femoral nerve. The correct attachments are the internal surface of the pelvic bone surrounding the obturator foramen and the greater trochanter of the femur, not the sacrum and patella. The correct action at the hip joint for the obturator internus is lateral rotation, not medial rotation.

The correct answer is the nerve Lumbrosacral Plexus (L5, S1) as it innervates the Inferior Gemellus muscle. The incorrect options do not correspond to the specific nerve, attachments, and actions related to the Inferior Gemellus muscle.

This question is related to the anatomy of the obturator externus muscle, focusing on its nerves, attachments, and actions. The correct nerve that innervates the obturator externus muscle is the Obturator nerve arising from the lumbar spinal nerves L3 and L4. The muscle has attachments on the external surface of the pelvic bone surrounding the obturator foramen proximally and on the trochanteric fossa of the femur distally. Its actions primarily involve lateral rotation of the thigh at the hip joint and contralateral rotation of the pelvis at the hip.

The correct answer is Lumbrosacral Plexus (L5, S1) as it innervates the Quadratus Femoris muscle.

The Superior Gluteal Nerve innervates the Gluteus Medius, Gluteus Minimus, and Tensor Fascia Latae. Gluteus Maximus is primarily innervated by the Inferior Gluteal Nerve. Piriformis is innervated by the Sacral Plexus. Sartorius is innervated by the Femoral Nerve.

The Gluteus Maximus is the only gluteal muscle innervated by the Inferior Gluteal Nerve, responsible for extension and outward rotation of the hip joint.

Hip rotators Piriformis, Superior Gemellus, Inferior Gemellus, Obturator Internus, and Quadratus Femoris are innervated by a nerve from the Lumbosacral Plexus. Gluteus Maximus, Sartorius, and Rectus Femoris are not innervated by the same nerve.

The Obturator Externus is the deep hip rotator muscle enervated by the Obturator Nerve.

The correct answer is Piriformis and Obturator Internus, both enervated by spinal segment S1 due to their anatomical location and function in the hip joint.

The Psoas muscle is the primary muscle of the hip flexors and is enervated by a nerve from the Lumbar Plexus. Gluteus Maximus, Rectus Abdominis, and Adductor Magnus are not directly enervated by nerves from the Lumbar Plexus.

The correct answer is the Iliacus muscle, which is innervated by the Femoral Nerve. The Psoas Major muscle is innervated by the Lumbar Plexus, the Rectus Femoris muscle is innervated by the Femoral Nerve but is part of the Quadriceps group, and the Pectineus muscle is innervated by the Obturator Nerve.

The Psoas muscle is located near the lower spine and pelvis. It plays a key role in hip flexion and is often referred to as the 'muscle of the soul' due to its connection with emotions and stress.

The correct answer is Iliacus, which is a major muscle of the pelvis. Sartorius, Teres Major, and Obliquus Externus Abdominis are different muscles with distinct functions in the body.

The correct answer is Gluteus Maximus, which is the largest muscle in the human body located in the buttocks. The other options are muscles found in different areas of the body.

The Gluteus Medius is one of the three gluteal muscles and is located on the outer surface of the pelvis. It is commonly known for its role in abduction of the hip.

Gluteus Minimus is a muscle located in the buttocks, while Biceps Femoris is a muscle in the thigh, Rectus Abdominis is a muscle in the abdomen, and Deltoid is a muscle in the shoulder. Therefore, Gluteus Minimus is the correct answer.

The correct name of this muscle is Obturator Externus, which is located in the hip region. Gluteus Maximus, Trapezius, and Sartorius are muscles in different areas of the body and are not the correct answer to this question.

The correct answer states that the Obturator Externus attaches to the trochanteric fossa of the femur and Quadratus Femoris attaches to the intertrochanteric crest of the femur. The incorrect answers provided have different attached points to the greater trochanter or obturator tuberosity.
