Peroneal Neuropathies
The common fibular nerve (also known as the common peroneal nerve, external popliteal nerve, or lateral popliteal nerve) is a nerve in the lower leg that provides sensation over the posterolateral part of the leg and the knee joint. It divides at the knee into two terminal branches: the superficial fibular nerve and deep fibular nerve, which innervate the muscles of the lateral and anterior compartments of the leg respectively. When the common fibular nerve is damaged or compressed, foot drop can ensue. Structure The common fibular nerve is the smaller terminal branch of the sciatic nerve. The common fibular nerve has root values of L4, L5, S1, and S2. It arises from the superior angle of the popliteal fossa and extends to the lateral angle of the popliteal fossa, along the medial border of the biceps femoris. It then winds around the neck of the fibula to pierce the fibularis longus and divides into terminal branches of the superficial fibular nerve and the deep fibular nerve. Bef ...

Anterior Compartment Of Leg
The anterior compartment of the leg is a fascial compartments of leg, fascial compartment of the lower leg. It contains muscles that produce Anatomical terms of motion#Flexion and extension of the foot, dorsiflexion and participate in Anatomical terms of motion#Inversion and eversion, inversion and eversion of the foot, as well as vascular and nervous elements, including the anterior tibial artery and anterior tibial vein, veins and the deep fibular nerve.

Fibula
The fibula or calf bone is a leg bone on the lateral side of the tibia, to which it is connected above and below. It is the smaller of the two bones and, in proportion to its length, the most slender of all the long bones. Its upper extremity is small, placed toward the back of the head of the tibia, below the knee joint and excluded from the formation of this joint. Its lower extremity inclines a little forward, so as to be on a plane anterior to that of the upper end; it projects below the tibia and forms the lateral part of the ankle joint. Structure The bone has the following components: * Lateral malleolus * Interosseous membrane connecting the fibula to the tibia, forming a syndesmosis joint * The superior tibiofibular articulation is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula. * The inferior tibiofibular articulation (tibiofibular syndesmosis) is formed by the rough, convex surface of the medial side of the lower end of the f ...

Fibular Veins
In anatomy, the fibular veins (also known as peroneal veins) are accompanying veins (venae comitantes) of the fibular artery. Structure The fibular veins are deep veins that help carry blood from the lateral compartment of the leg. They drain into the posterior tibial veins, which in turn drain into the popliteal vein. The fibular veins accompany the fibular artery. See also * Fibular artery * Common fibular nerve * Venae comitantes Additional images File:Gray440_color.png, Cross-section through middle of leg.

Peroneal Strike
A peroneal strike is a temporarily disabling blow to the common fibular (peroneal) nerve of the leg, just above the knee. The attacker aims roughly a hand span above the exterior side of the knee, towards the back of the leg. This causes a temporary loss of motor control of the leg, accompanied by numbness and a painful tingling sensation from the point of impact all the way down the leg, usually lasting anywhere from 30 seconds to 5 hours in duration. The strike is commonly made with the knee, a baton, or shin kick, but can be done by anything forcefully impacting the nerve. The technique is a part of the pressure point control tactics used in martial arts and by law enforcement agents. The peroneal strike was used against detainees during the 2002 Bagram torture and prisoner abuse scandal.Rashid, Ahmed.

Rembrandt - The Anatomy Lesson Of Dr Nicolaes Tulp
Rembrandt Harmenszoon van Rijn (, ; 15 July 1606 – 4 October 1669), usually simply known as Rembrandt, was a Dutch Golden Age painter, printmaker and draughtsman. An innovative and prolific master in three media, he is generally considered one of the greatest visual artists in the history of art and the most important in Dutch art history.Gombrich, p. 420. Unlike most Dutch masters of the 17th century, Rembrandt's works depict a wide range of style and subject matter, from portraits and self-portraits to landscapes, genre scenes, allegorical and historical scenes, biblical and mythological themes and animal studies. His contributions to art came in a period of great wealth and cultural achievement that historians call the Dutch Golden Age, when Dutch art (especially Dutch painting), whilst antithetical to the Baroque style that dominated Europe, was prolific and innovative. This era gave rise to important new genres. Like many artists of the Dutch Golden Age, su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extensor Digitorum Brevis Muscle
The extensor digitorum brevis muscle (sometimes EDB) is a muscle on the upper surface of the foot that helps extend digits 2 through 4. Structure The muscle originates from the forepart of the upper and lateral surface of the calcaneus (in front of the groove for the peroneus brevis tendon), from the interosseous talocalcaneal ligament and the stem of the inferior extensor retinaculum. The fibres pass obliquely forwards and medially across the dorsum of the foot and end in four tendons. The medial part of the muscle, also known as extensor hallucis brevis, ends in a tendon which crosses the dorsalis pedis artery and inserts into the dorsal surface of the base of the proximal phalanx of the great toe. The other three tendons insert into the lateral sides of the tendons of extensor digitorum longus for the second, third and fourth toes.

Johns Hopkins School Of Medicine
The Johns Hopkins University School of Medicine (JHUSOM) is the medical school of Johns Hopkins University, a private research university in Baltimore, Maryland. Founded in 1893, the School of Medicine shares a campus with the Johns Hopkins Hospital and Johns Hopkins Children's Center, established in 1889. It has consistently ranked among the top medical schools in the United States in terms of the number/amount of research grants/funding awarded by the National Institutes of Health, among other measures. History The founding physicians (the "Four Doctors") of the Johns Hopkins School of Medicine included pathologist William Henry Welch (1850–1934), the first dean of the school and a mentor to generations of research scientists; a Canadian, internist Sir William Osler (1849–1919), regarded as the ''Father of Modern Medicine'', having been perhaps the most influential physician of the late 19th and early 20th centuries as author of '' The Principles and Practice of Medicine'' ...

Yoga Foot Drop
Vajrasana (), Thunderbolt Pose, or Diamond Pose, is a kneeling asana in hatha yoga and modern yoga as exercise. Ancient texts describe a variety of poses under this name. Etymology and origins The name comes from the Sanskrit words ''vajra'', a weapon whose name means "thunderbolt" or "diamond", and ''asana'' (आसन, āsana) meaning "posture" or "seat". The name Vajrasana denotes a medieval meditation seat, but its usage varied. The 15th century '' Hatha Yoga Pradipika'' called it a synonym of Siddhasana, where one of the heels presses the root of the penis; according to ''Yoga-Mimamsa'' III.2 p. 135, this explains the reference to the vajra weapon. The 17th century '' Gheranda Samhita'' 2.12 describes what '' Light on Yoga'' calls Virasana, with the feet beside the buttocks, while in other texts Vajrasana appears to mean the modern kneeling-down position, with the buttocks resting on the feet. The yoga scholar Norman Sjoman notes that ''Light on Yoga'' is unclear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yoga
Yoga (; sa, योग, lit=yoke' or 'union ) is a group of physical, mental, and spiritual practices or disciplines which originated in ancient India and aim to control (yoke) and still the mind, recognizing a detached witness-consciousness untouched by the mind ('' Chitta'') and mundane suffering (''Duḥkha''). There is a wide variety of schools of yoga, practices, and goals in Hinduism, Buddhism, and Jainism,Stuart Ray Sarbacker, ''Samādhi: The Numinous and Cessative in Indo-Tibetan Yoga''. SUNY Press, 2005, pp. 1–2.Tattvarthasutra .1 see Manu Doshi (2007) Translation of Tattvarthasutra, Ahmedabad: Shrut Ratnakar p. 102. and traditional and modern yoga is practiced worldwide. Two general theories exist on the origins of yoga. The linear model holds that yoga originated in the Vedic period, as reflected in the Vedic textual corpus, and influenced Buddhism; according to author Edward Fitzpatrick Crangle, this model is mainly supported by Hindu scholars.
