Muscles of the Abdomen

Muscles of the Abdomen

The abdominal wall encircles the abdominal cavity, providing flexible protection and shielding the internal organs from harm. It is bordered at the top by the xiphoid process and costal margins, at the back by the vertebral column, and at the bottom by the pelvic bones and inguinal ligament. The abdominal wall is divided into two regions — the anterolateral and posterior regions.
Anterolateral Region
The anterolateral region comprises five paired muscles classified into the lateral and anterior...

Muscles that Move the Thigh

Muscles that Move the Thigh

The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar fascia...

Muscles of the Pelvic Floor and Perineum

Muscles of the Pelvic Floor and Perineum

The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

Bones of the Lower Limb: Femur and Patella

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...

Gross Anatomy of the Liver

Gross Anatomy of the Liver

The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is covered...

Muscles that Move the Leg

Muscles that Move the Leg

The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...

Summary

A newly identified broad ligament, termed the "pyriform ligament," connects the pyriform rim to the nasal cartilages. This anatomical structure may influence nasal tip shape and projection.

Area of Science:

Anatomy
Rhinoplasty Surgery

Background:

Ligaments supporting the nasal tip are crucial for nasal structure.
Intraoperative findings suggest a broader ligament along the pyriform rim than previously documented.

Purpose of the Study:

To investigate the existence and extent of a ligamentous connection between the pyriform rim and nasal tip cartilages.
To define the anatomical relationship of this potential ligament to existing nasal structures.

Main Methods:

Ten fresh hemifacial cadaver dissections were performed.
Sequential dissection utilized magnification (loupes and operating microscope).
Fascial connections between the pyriform rim, upper and lower lateral cartilages, and alar base were meticulously defined.

Main Results:

A dense fascial system, originating from the pyriform rim periosteum, was consistently observed in all dissections.
This ligamentous system inserts onto both upper and lower lateral cartilages, encompassing known structures like the lateral sesamoid complex.
The fascia spans the pyriform rim from the nasal bone to the anterior nasal spine.

Conclusions:

A broad and expansive ligamentous structure, the
