Common Fibular Nerve
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 compartment of the lower leg. It contains muscles that produce dorsiflexion and participate in inversion and eversion of the foot, as well as vascular and nervous elements, including the anterior tibial artery and veins and the deep fibular nerve. Muscles The muscles of the compartment are: * tibialis anterior * extensor hallucis longus * extensor digitorum longus * fibularis (peroneus) tertius Function The compartment contains muscles that are dorsiflexors and participate in inversion and eversion of the foot. Innervation and blood supply The anterior compartment of the leg is supplied by the deep fibular nerve (deep peroneal nerve), a branch of the common fibular nerve. The nerve contains axons An axon (from Greek ἄξων ''áxōn'', axis), or nerve fiber (or nerve fibre: see spelling differences), is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrica ...

Fibula
The fibula or calf bone is a human leg, leg bone on the Lateral (anatomy), 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 Upper extremity of tibia, head of the tibia, below the knee, 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, 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 tibia, lateral condyle of the tibia and the head of the fibula. * The inferior tibiofibular articulation (tibiofibular synd ...

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 agent The police are a constituted body of persons empowered by a state, with the aim to enforce the law, to ensure the safety, health and possessions of citizens, and to prevent crime and civil disorder. Their lawful powers include arrest and th ...s. The peroneal strike was used against det ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
