AlachrymaRotator cuff tearBiceps femoris tendon avulsion: The biceps femoris is commonly injured in sports that require explosive bending of the knee as seen in sprinting. If the athlete is fatigued or has not warmed up properly he/she may suffer a hamstring strain/rupture, which is the tearing of the hamstring muscle.ArthroscopyDiscoid meniscus: Discoid meniscus is a rare human anatomic variant that usually affects the lateral meniscus of the knee.http://www.Ottawa knee rules: The Ottawa Knee Rules are a set of rules used to help physicians determine whether an x-ray of the knee is needed.http://www.Shoulder arthritis: Shoulder arthritis can be one of three types of arthritis in the glenohumeral joint of the shoulder. The glenohumeral joint is a ball and socket joint, which relies on cartilage to move smoothly and to operate normally.Von Ebner's gland: Von Ebner's glands, also called Ebner's glands or gustatory glands, are exocrine glands found in the mouth. More specifically, they are serous salivary glands which reside adjacent to the moats surrounding the circumvallate and foliate papillae just anterior to the posterior third of the tongue, anterior to the terminal sulcus.Killed or Seriously Injured: Killed or Seriously Injured (KSI) is a standard metric for safety policy, particularly in transportation and road safety.Artificial tearsAnterior meniscofemoral ligament: The anterior meniscofemoral ligament (ligament of Humphrey) is a small fibrous band of the knee joint. It arises from the posterior horn of the lateral meniscus and passes superiorly and medially in front of the posterior cruciate ligament to attach to the lateral surface of medial condyle of the femur.Anterior cruciate ligament reconstructionConjunctiva: The conjunctiva lines the inside of the eyelids and covers the sclera (white part of the eye). It is composed of non-keratinized, stratified columnar epithelium with goblet cells, and also stratified columnar epithelium.Sulcus sign: The Sulcus sign is an orthopedic evaluation test for glenohumeral instability of the shoulder. With the arm straight and relaxed to the side of the patient, the elbow is grasped and traction is applied in an inferior direction.EpisiotomyPes anserinus (leg): Pes anserinus ("goose foot") refers to the conjoined tendons of three muscles that insert onto the anteromedial (front and inside) surface of the proximal extremity of the tibia. The muscles are the sartorius, gracilis and semitendinosus.Allergic conjunctivitisArthrogramOptic disc pit: An optic disc pit is a congenital excavation (or regional depression) of the optic nerve head resulting from a malformation during development of the eye. Optic pits are important because they are associated with posterior vitreous detachments (PVD) and even serous retinal detachments.HyperintensityCircular knittingObstetric labor complicationDescending perineum syndrome: Descending perineum syndrome (also known as Levator plate sagging) refers to a condition where the perineum "balloons" several centimeters below the bony outlet of the pelvis during strain, although this descent may happen without straining. The syndrome was first described in 1966 by Parks et al.Meibomian gland: The meibomian glands (or tarsal glands) are a special kind of sebaceous gland at the rim of the eyelids inside the tarsal plate, responsible for the supply of meibum, an oily substance that prevents evaporation of the eye's tear film. Meibum prevents tear spillage onto the cheek, trapping tears between the oiled edge and the eyeball, and makes the closed lids airtight.Quadriceps tendon: In human anatomy, the quadriceps tendon, also known as the patellar tendon, allows the quadriceps femoris muscles (rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius)Saladin, Kenneth S. Anatomy & Physiology: The Unity of Form and Function.Fairness to Contact Lens Consumers Act: The Fairness to Contact Lens Consumers Act (, 117 Stat. 2025, 2026, 2027, 2028 and 2029, codified at et seq.Jim McKeever (baseball)Henry Beighton: Henry Beighton (c. 20 August 1687 – 9 October 1743) was an English engineer and surveyor.Endoanal ultrasound: Endoanal ultrasound is a type of medical investigation which images the structures of the anal canal.Lactoferrin: Lactoferrin (LF), also known as lactotransferrin (LTF), is a multifunctional protein of the transferrin family. Lactoferrin is a globular glycoprotein with a molecular mass of about 80 kDa that is widely represented in various secretory fluids, such as milk, saliva, tears, and nasal secretions.TenotomyXerophthalmiaSaliva testing: Saliva testing is a diagnostic technique that involves laboratory analysis of saliva to identify markers of endocrine, immunologic, inflammatory, infectious, and other types of conditions. Saliva is a useful biological fluid for assaying steroid hormones such as cortisol, genetic material like RNA, proteins such as enzymes and antibodies, and a variety of other substances, including natural metabolites, including saliva nitrite, a biomarker for nitric oxide status (see below for Cardiovascular Disease, Nitric Oxide: a salivary biomarker for cardio-protection).Z-plastyLigneous conjunctivitis: Ligneous conjunctivitis is a rare form of chronic conjunctivitis characterized by recurrent, fibrin-rich pseudomembranous lesions of wood-like consistency that develop mainly on the underside of the eyelid (tarsal conjunctiva). It is generally a systemic disease which may involve the periodontal tissue, the upper and lower respiratory tract, kidneys, middle ear, and female genitalia.Bankart lesionSecretory componentDacryoadenitisDebridement (dental)Mechanochemistry: Mechanochemistry or mechanical chemistry is the coupling of mechanical and chemical phenomena on a molecular scale and includes mechanical breakage, chemical behaviour of mechanically stressed solids (e.g.Knee pain: Knee pain is a common complaint for many people. There are several factors that can cause knee pain.Tendinitis
