The popliteal fossa or the “knee pit” is a diamond-shaped, fat-filled, shallow depression on the posterior aspect of the knee joint.
What is the meaning of popliteal fossa?
The Popliteal Fossa is a diamond-shaped space behind the knee joint. It is formed between the muscles in the posterior compartments of the thigh and leg. This anatomical landmark is the major route by which structures pass between the thigh and leg.
What does popliteal vein turn into?
The popliteal vein forms from the posterior and anterior tibial veins and ascends through the popliteal fossa to the opening in adductor magnus alongside the popliteal artery where it becomes the femoral vein.
What does the word popliteal refer to anatomically?
The definition of popliteal refers to something related to or situated at the hollow in the back of your knee. … Of or relating to the hollow part of the leg behind the knee joint. adjective. (anatomy) Pertaining to the area behind the knee.What travels through the popliteal fossa?
The tibial and common fibular nerves are the most superficial of the contents of the popliteal fossa. They are both branches of the sciatic nerve. The common fibular nerve follows the biceps femoris tendon, travelling along the lateral margin of the popliteal fossa.
What is the function of the popliteal?
The popliteus muscle plays an important role in the gait cycle by initiating the flexion of the fully extended (“locked”) knee. Thus, the popliteus is referred to as the “key to unlock the knee”. In addition, the popliteus muscle is the main stabilizer of the dorsal knee region.
Why is the popliteal fossa important?
Important nerves and vessels pass from the thigh to the leg by traversing through this fossa. … These include the two terminal branches of the sciatic nerve, the popliteal vessels and short saphenous vein. Several muscles of the thigh and leg form the boundaries of the popliteal fossa.
What is the definition of a scapular?
Definition of scapula : either of a pair of large triangular bones lying one in each dorsal lateral part of the thorax, being the principal bone of the corresponding half of the shoulder girdle, and articulating with the corresponding clavicle or coracoid. — called also shoulder blade.What is meant by fossa?
: an anatomical pit, groove, or depression the temporal fossa of the skull the fossa in the liver for the gallbladder.
What veins are in the popliteal fossa?The popliteal vein is found within the popliteal fossa. The popliteal fossa is defined by the biceps femoris proximolaterally; the semimembranosus and semitendinosus muscles proximomedially; and gastrocnemius distally. The tibial nerve, popliteal vein, and popliteal artery are all found within the fossa.
Article first time published onWhere is your popliteal?
Location. The anatomical region where the popliteal vein is located is called the popliteal fossa. The popliteal fossa is a diamond-shaped area at the back of the knee, which you might think of as the “pit” of your knee.
What is the ulnar vein?
The ulnar veins are deep paired vessels of the forearm. They arise from the deep venous palmar arch and run superiorly in the deep anterior compartment of the forearm. They terminate in the cubital fossa where they join the radial veins to form the brachial veins.
Why is popliteus called the Key of knee joint?
When the knee is in full extension, the femur slightly medially rotates on the tibia to lock the knee joint in place. Popliteus is often referred to as the “Key” to unlocking the knee since it begins knee flexion by laterally rotating the femur on the tibia.
What is muscle behind knee called?
The gastrocnemius muscle and the soleus muscle make up your calf, which is the back of your lower leg. These muscles help you bend your knee and point your toes. Any sport that requires you to quickly go from a standing position to a run — like tennis or squash — can strain or tear the gastrocnemius muscle.
What does the back of the knee called?
The popliteal fossa (sometimes referred to as hough, or kneepit in analogy to the cubital fossa) is a shallow depression located at the back of the knee joint.
Which bones contain a fossa?
The middle cranial fossa consists of three bones – the sphenoid bone and the two temporal bones. Its boundaries are as follows: Anteriorly and laterally it is bounded by the lesser wings of the sphenoid bone. These are two triangular projections of bone that arise from the central sphenoid body.
Where are the fossa located?
Vulnerable. A relative of the mongoose, the fossa is unique to the forests of Madagascar, an African island in the Indian Ocean. Growing up to 6 feet long from nose to tail tip, and weighing up to 26 pounds, the fossa is a slender-bodied catlike creature with little resemblance to its mongoose cousins.
What family is the fossa in?
The fossa has features in common with three different families of carnivores: Herpestidae (mongooses), Viverridae (civets and their relatives), and Felidae (cats). Recent molecular studies have put the fossa in the Eupleridae family, a group that consists of Malagasy carnivores.
How do you pronounce Fossas?
So this is where it gets complicated: Fossa fossa is the Latin name for an entirely different Malagasy civet, and is pronounced as the Latin normally would be: fos-sa or foh-suh, per your continent.
What causes pain in the popliteal fossa?
Popliteal fossa pain is developed by a wide variety of causes. The most common causes are Baker’s cyst, soft tissue or bone tumor and injury to the meniscus, hamstring, popliteal tendon or ligament.
Where does the popliteal vein drain into?
The popliteal vein is a deep vein of the leg. It drains blood away from the leg into the femoral vein, which drains blood to the inferior vena cava to return to the right atrium of the heart.
What is the scapula called?
scapula, also called shoulder blade, either of two large bones of the shoulder girdle in vertebrates. In humans they are triangular and lie on the upper back between the levels of the second and eighth ribs.
What is the shape of scapula?
The scapula is a flat, triangular-shaped bone (colloquially as the “shoulder blade”). It is located in the upper thoracic region on the dorsal surface of the rib cage.
What is the promise of the Brown scapular?
A traditional formulation of the Scapular Promise is “Take this Scapular. Whosoever dies wearing it shall not suffer eternal fire. It shall be a sign of salvation, a protection in danger and pledge of peace.” A central belief about the Brown Scapular is its signification of the wearer’s consecration to Mary.
What is popliteal nerve?
The popliteal block is a peripheral nerve block of the sciatic nerve at the level of the popliteal fossa. The sciatic nerve provides sensory and motor innervation of most of the lower leg. Thus the popliteal block is used for anesthesia and analgesia for a wide variety of surgical procedures below the knee.
What is the longest vein in the body?
Great Saphenous Vein (GSV) – The GSV is the large superficial vein of the leg and the longest vein in the entire body. It can be found along the length of the lower limb, returning blood from the thigh, calf, and foot to the deep femoral vein at the femoral triangle. The femoral triangle is located in the upper thigh.
Is popliteal vein superficial or deep?
The popliteal vein is a deep vein of the leg located behind the knee. This vein carries blood from your legs back to your heart.
Where does the popliteal artery start and end?
The popliteal artery is a deeply placed continuation of the femoral artery opening in the distal portion of the adductor magnus muscle. It courses through the popliteal fossa and ends at the lower border of the popliteus muscle, where it branches into the anterior and posterior tibial arteries.
Where is the fibular vein located?
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 will in turn drain into the popliteal vein. The fibular veins accompany the fibular artery.
Which vein drains the ankle and foot?
In human anatomy, there are two anterior tibial veins. They originate and receive blood from the dorsal venous arch, on the back of the foot and empties into the popliteal vein. The anterior tibial veins drain the ankle joint, knee joint, tibiofibular joint, and the anterior portion of the lower leg.
Where is the brachial vein?
The brachial artery and vein can be found by palpating the medial intermuscular septum in the proximal and middle thirds of the arm. The vein is medial and posterior to the artery in this area.
