The lacrimal sac is the structure on the medial aspect of each eye that drains tears into the nose. Tears produced by the eye drain through the lacrimal puncta, then pass through the canaliculi and into the lacrimal sac before flowing into the nose via the nasolacrimal duct.
Signal intensity refers to the brightness of an image on a magnetic resonance imaging (MRI) scan. When evaluating the medial meniscus, signal intensity can help identify abnormalities such as tears or degeneration. Changes in signal intensity of the medial meniscus can indicate injury or pathology.
The nasolacrimal duct is responsible for draining excess tears from the eyes to the nasal cavity, which can cause the nose to run. Tears are produced in the lacrimal glands and then flow across the surface of the eye to the corner of the eye, where the nasolacrimal duct is located. From there, tears drain into the nasal cavity, which can lead to a runny nose.
The conical body in the medial corner of the eye is the lacrimal caruncle. It is a small, fleshy mass that contains sebaceous and sweat glands, as well as hair follicles. Its main function is to produce a small amount of tears to keep the eye moist.
The medial meniscus is more likely to be injured than the lateral meniscus due to its attachment to the medial collateral ligament (MCL), which restricts its mobility and makes it more susceptible to injury during twisting motions of the knee. Additionally, the medial meniscus has a C-shape that makes it more prone to tears, especially during activities that involve rapid changes in direction or weight-bearing. The lateral meniscus, being more mobile and less tethered to surrounding structures, often sustains fewer injuries.
Medial meniscus posterior horn intrasubstance signal refers to abnormalities seen in the inner portion of the back part of the knee meniscus on MRI imaging. This signal can indicate degeneration, tears, or other injuries to the meniscus in that specific area, which may require further evaluation and treatment.
The red structure in the medial eye is the conjunctiva, which is a thin, transparent membrane that covers the white part of the eye (sclera) and lines the inside of the eyelids. Its main function is to protect the eye and keep it moist by producing mucus and tears.

Common injuries associated with the medial side of the lower limb include medial collateral ligament (MCL) sprains, medial meniscus tears, and pes anserine bursitis. These injuries often occur during activities that involve twisting or direct impact to the inner part of the knee or lower leg.
A medial collateral ligament (MCL) injury can vary from mild to severe, depending on the extent of the damage. Mild MCL tears may heal on their own with rest, while severe tears may require surgery and extensive rehabilitation. It is important to seek medical evaluation to determine the severity of the injury and the appropriate treatment plan.

The medial canthus is the point where the upper and lower eyelids meet on the inner side of the eye. It helps to protect the eye by preventing foreign particles from entering the eye and also assists in the proper drainage of tears through the tear ducts.
The tear ducts are called the lacrimal ducts. The duct that drains the tears from your eye (located in the nasal corner of the eye) is called the nasolacrimal duct.

Tears aren't just made out of water, they are made from tear film and a microscopically three-layered structure.
its chemical structure. because of its design it literally tears off molecules from other compounds. i believe it is called a hyperbolic structure
