Gluteal ligaments | Sacrospinous and Sacrotuberous ligament | Anatomy | Knowing anatomy
The two primary ligaments of the gluteal region are the sacrotuberous ligament and the sacrospinous ligament.
The large sacrotuberous ligament (STL) is continuous from the posterior sacro-iliac ligament and spans the length of the posterior superior iliac spine,the lateral portion of the sacrum, the upper coccyx and connects to the ischial tuberosity of the ischium. The most inferior and superficial fibers of this ligament are continuous with the tendon of the biceps femoris muscle.
Functionally, the STL plays a significant role in stabilizing the pelvis through inhibiting nutation (anterior and inferior movement of the sacrum), anatomically it serves as a point of origin for the inferior fibers of the gluteus maximus, and structurally along with the contribution of the sacrospinous ligament, divides the sciatic notch into the greater sciatic foramen and lesser sciatic foramen. This creation of the sciatic foramen created via these two ligaments, is an important anatomical division as the greater sciatic foramen serves as the main route for all arterial and nerve structures transitioning from the pelvis to the gluteal region, while the lesser sciatic foramen serves as the route for arterial and nervous structures entering and leaving the perineum.

Atrophic rhinitis is a chronic disease of the nasal mucosa. The disease is characterized by abnormally wide nasal cavities, and its main symptoms are dryness, crusting, atrophy, fetor, and a paradoxical sensation of nasal congestion. The etiology of the disease remains unknown. Here, we propose that excessive evaporation of the mucous layer is the basis for the relentless nature of this disease...

Muscle tone is traditionally defined as 'the tension in the relaxed muscle' or 'the resistance, felt by the examiner during passive stretching of a joint when the muscles are at rest'. What is muscle tone and what causes it? Muscle tone is regulated by signals that travel from the brain to the nerves and tell the muscle to contract. Hypertonia happens when the regions of the brain or spinal cor...

A group of pus-filled bumps forming a connected area of infection under the skin. Carbuncles form when one or more hair follicles get infected. They often occur on the back of the neck, shoulders or thighs. Carbuncles fill with pus, growing larger and more painful until they rupture and drain. In rare but severe cases, people may feel unwell and experience fever and chills. Sometimes carbuncles...

abscess, a localized collection of pus in a cavity formed from tissues that have been broken down by infectious bacteria. An abscess is caused when such bacteria as staphylococci or streptococci gain access to solid tissue (e.g., by means of a small wound on the skin). The toxins released by these multiplying bacteria destroy cells and thus trigger an acute inflammation at the site, with its ch...

A dermoid cyst is a benign cutaneous developmental anomaly that arises from the entrapment of ectodermal elements along the lines of embryonic closure. These benign tumors are lined by stratified squamous epithelium with mature skin appendages found on their wall and their lumens filled with keratin and hair.

A pterygium (from the Greek, pterygos, “little wing”) is a wing-shaped, vascular, fleshy growth that originates on the conjunctiva and that can spread to the corneal limbus and beyond. Pterygia are relatively common in the general population and typically follow an indolent course, with changes in appearance but little effect on vision and the eye itself. Because early pterygia are usually asym...

Bing's test; occlusion test. Test used to distinguish between conductive and sensorineural hearing losses. A vibrating tuning fork is placed on the center of the subject’s forehead and the external acoustic meatus is gently occluded. If the ear is normal or if there is a pure sensorineural hearing loss present, the loudness to a low-frequency stimulus is increased, but if there is a conductive ...

Gelle test: In this test, the air pressure in the external canal is varied using a Siegle’s speculum. The vibrating fork is held in contact with the mastoid process. In normal individuals and in those with sensorineural hearing loss, increased pressure in the external meatus causes a decrease in the loudness of the bone conducted sound. In stapes fixation no alteration in the hearing threshold ...
