Profunda Femoris
The deep artery of the thigh, (profunda femoris artery or deep femoral artery) is a large branch of the femoral artery. It travels more deeply (posteriorly) than the rest of the femoral artery. Structure The deep artery of the thigh branches off the posterolateral side of the femoral artery soon after its origin. It travels down the thigh closer to the femur than the femoral artery. It runs between the pectineus muscle and the adductor longus muscle. It runs on the posterior side of adductor longus muscle. It pierces the adductor magnus muscle, and may be known as the fourth perforating artery as it continues. The deep femoral artery does not leave the thigh. Branches The deep artery of the thigh gives off the following branches: * Lateral circumflex femoral artery. * Medial circumflex femoral artery. * 3 Perforating arteries - perforate the adductor magnus muscle to the posterior and medial compartments of the thigh to connect with the branches of the popliteal artery behind t ...

Femoral Artery
The femoral artery is a large artery in the thigh and the main arterial supply to the thigh and leg. The femoral artery gives off the deep femoral artery or profunda femoris artery and descends along the anteromedial part of the thigh in the femoral triangle. It enters and passes through the adductor canal, and becomes the popliteal artery as it passes through the adductor hiatus in the adductor magnus near the junction of the middle and distal thirds of the thigh. Structure The femoral artery enters the thigh from behind the inguinal ligament as the continuation of the external iliac artery. Here, it lies midway between the anterior superior iliac spine and the symphysis pubis (Mid-inguinal point). Segments In clinical parlance, the femoral artery has the following segments: *The common femoral artery (CFA) is the segment of the femoral artery between the inferior margin of the inguinal ligament and the branching point of the deep femoral artery/profunda femoris artery.

Thigh
In human anatomy, the thigh is the area between the hip (pelvis) and the knee. Anatomically, it is part of the lower limb. The single bone in the thigh is called the femur. This bone is very thick and strong (due to the high proportion of bone tissue), and forms a ball and socket joint at the hip, and a modified hinge joint at the knee. Structure Bones The femur is the only bone in the thigh and serves as an attachment site for all muscles in the thigh. The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia and patella forming the knee. By most measures, the femur is the strongest bone in the body. The femur is also the longest bone in the body. The femur is categorised as a long bone and comprises a diaphysis, the shaft (or body) and two epiphysis or extremities that articulate with adjacent bones in the hip and knee. Muscular compartments In cross-section, the thigh is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blood
Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells. Blood in the circulatory system is also known as ''peripheral blood'', and the blood cells it carries, ''peripheral blood cells''. Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets (also called thrombocytes). The most abundant cells in vertebrate blo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fascial Compartment
A fascial compartment is a section within the body that contains muscles and nerves and is surrounded by deep fascia. In the human body, the limbs can each be divided into two segments – the upper limb can be divided into the arm and the forearm and the sectional compartments of both of these – the fascial compartments of the arm and the fascial compartments of the forearm contain an anterior and a posterior compartment. Likewise, the lower limbs can be divided into two segments – the leg and the thigh – and these contain the fascial compartments of the leg and the fascial compartments of the thigh. Structure If these segments are cut transversely, it is apparent that they are divided into multiple sections. These are called fascial compartments, and are formed by tough connective tissue septa. These compartments usually have a nerve and blood supply separate from their neighbours. The muscles in each compartment will often all be supplied by the same nerve. Sometim ...

Medial Circumflex Femoral Artery
The medial circumflex femoral artery (internal circumflex artery, medial femoral circumflex artery) is an artery in the upper thigh that arises from the profunda femoris artery''.'' Damage to the artery following a femoral neck fracture may lead to avascular necrosis (ischemic) of the femoral neck/head. Structure Origin The medial femoral circumflex artery arises from the posterior medial aspect of the profunda femoris artery''.'' The medial femoral circumflex artery may occasionally arise directly from the femoral artery. Course and relations It winds around the medial side of the femur, passing first between the pectineus and iliopsoas muscles, and then between the obturator externus and the adductor brevis muscles. Branches At the upper border of the adductor brevis it gives off two branches: * The '' ascending branch'' * The ''descending branch'' descends beneath the adductor brevis, to supply it and the adductor magnus; the continuation of the vessel passes backward ...

Lateral Circumflex Femoral Artery
The lateral circumflex femoral artery, also known as the lateral femoral circumflex artery, or the external circumflex artery, is an artery in the upper thigh. It is usually a branch of the profunda femoris artery, and produces three branches. It is mostly distributed to the muscles of the lateral thigh. Structure Origin The lateral femoral circumflex artery usually arises from the lateral side of the profunda femoris artery, but may occasionally arise directly from the femoral artery. It is the largest branch of the profunda femoris artery. Course and relations The lateral circumflex femoral artery usually courses anterior to the femoral neck. It passes horizontally between the divisions of the femoral nerve. It passes posterior to the sartorius muscle and rectus femoris muscle. It passes laterally across the hip joint capsule. It divides into ascending, transverse, and descending branches. Branches The lateral circumflex femoral artery has three branches: # The ascending ...

Adductor Longus Muscle
In the human body, the adductor longus is a skeletal muscle located in the thigh. One of the adductor muscles of the hip, its main function is to adduct the thigh and it is innervated by the obturator nerve. It forms the medial wall of the femoral triangle. Structure The adductor longus arises from the body of pubis inferior to pubic crest and lateral to pubic symphysis. It lies ventrally on the adductor magnus, and near the femur, the adductor brevis is interposed between these two muscles. Distally, the fibers of the adductor longus extend into the adductor canal. It is inserted into the middle third of the medial lip of the ''linea aspera''. Innervation As part of the medial compartment of the thigh, the adductor longus is innervated by the anterior division (sometimes the posterior division) of the obturator nerve. The obturator nerve exits via the anterior rami of the spinal cord from L2, L3, and L4.Saladin, Kenneth S. Anatomy & Physiology: The Unity of Form and Funct ...

Pectineus Muscle
The pectineus muscle (, from the Latin word ''pecten'', meaning comb) is a flat, quadrangular muscle, situated at the anterior (front) part of the upper and medial (inner) aspect of the thigh. The pectineus muscle is the most anterior adductor of the hip. The muscle does adduct and internally rotate the thigh but its primary function is hip flexion. It can be classified in the medial compartment of thigh (when the function is emphasized) or the anterior compartment of thigh (when the nerve is emphasized). Structure The pectineus muscle arises from the pectineal line of the pubis and to a slight extent from the surface of bone in front of it, between the iliopectineal eminence and pubic tubercle, and from the fascia covering the anterior surface of the muscle; the fibers pass downward, backward, and lateral, to be inserted into the pectineal line of the femur which leads from the lesser trochanter to the linea aspera.
