Pulmonary Embolism
Pulmonary embolism (PE) is a blockage of an artery in the lungs by a substance that has moved from elsewhere in the body through the bloodstream ( embolism). Symptoms of a PE may include shortness of breath, chest pain particularly upon breathing in, and coughing up blood. Symptoms of a blood clot in the leg may also be present, such as a red, warm, swollen, and painful leg. Signs of a PE include low blood oxygen levels, rapid breathing, rapid heart rate, and sometimes a mild fever. Severe cases can lead to passing out, abnormally low blood pressure, obstructive shock, and sudden death. PE usually results from a blood clot in the leg that travels to the lung. The risk of blood clots is increased by advanced age, cancer, prolonged bed rest and immobilization, smoking, stroke, long-haul travel over 4 hours, certain genetic conditions, estrogen-based medication, pregnancy, obesity, trauma or bone fracture, and after some types of surgery. A small proportion of cases are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Limb
The human leg, in the general word sense, is the entire lower limb of the human body, including the foot, thigh or sometimes even the hip or gluteal region. However, the definition in human anatomy refers only to the section of the lower limb extending from the knee to the ankle, also known as the crus or, especially in non-technical use, the shank. Legs are used for standing, and all forms of locomotion including recreational such as dancing, and constitute a significant portion of a person's mass. Female legs generally have greater hip anteversion and tibiofemoral angles, but shorter femur and tibial lengths than those in males. Structure In human anatomy, the lower leg is the part of the lower limb that lies between the knee and the ankle. Anatomists restrict the term ''leg'' to this use, rather than to the entire lower limb. The thigh is between the hip and knee and makes up the rest of the lower limb. The term ''lower limb'' or ''lower extremity'' is commonly used to des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abduction (kinesiology)
Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved. Anatomists and others use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing unique movements such as those of the hands, feet, and eyes. In general, motion is classified according to the anatomical plane it occurs in. ''Flexion'' and ''extension'' are examples of ''angular'' motions, in which two axes of a joint are brought closer together or moved further apart. ''Rotational'' motion may occur at other joints, for example the shoulder, and are described as ''internal'' or ''external''. Other terms, such as ''elevation'' and ''depression'', describe movement above or below the horizontal plane. Many anatom ...

Gait (human)
A gait is a pattern of limb movements made during locomotion. Human gaits are the various ways in which humans can move, either naturally or as a result of specialized training. Human gait is defined as bipedal, biphasic forward propulsion of the center of gravity of the human body, in which there are alternate sinuous movements of different segments of the body with least expenditure of energy. Gait patterns are characterized by differences in limb-movement patterns, overall velocity, forces, kinetic and potential energy cycles, and changes in contact with the ground. Classification Human gaits are classified in various ways. Each gait can be generally categorized as either natural (one that humans use instinctively) or trained (a non-instinctive gait learned via training). Examples of the latter include hand walking and specialized gaits used in martial arts. Gaits can also be categorized according to whether the person remains in continuous contact with the ground.

Trendelenburg Gait
Trendelenburg gait, named after Friedrich Trendelenburg, is an abnormal gait. It is caused by weakness or ineffective action of the gluteus medius muscle and the gluteus minimus muscle. Gandbhir and Rayi point out that the biomechanical action involved comprises a Class 3 lever, where the lower limb's weight is the load, the hip joint is the fulcrum, and the lateral glutei, which attach to the antero-lateral surface of the greater trochanter of the femur, provide the effort. The causes can thus be categorized systematically as failures of this lever system at various points. Signs and symptoms During the stance phase, or when standing on one leg, the weakened abductor muscles allow the pelvis to tilt down on the opposite side. To compensate, the trunk lurches to the weakened side to attempt to maintain a level pelvis throughout the gait cycle. When the hip abductor muscles (gluteus medius and minimus) are weak or ineffective, the stabilizing effect of these muscles during ga ...

Larynx
The larynx (), commonly called the voice box, is an organ in the top of the neck involved in breathing, producing sound and protecting the trachea against food aspiration. The opening of larynx into pharynx known as the laryngeal inlet is about 4–5 centimeters in diameter. The larynx houses the vocal cords, and manipulates pitch and volume, which is essential for phonation. It is situated just below where the tract of the pharynx splits into the trachea and the esophagus. The word ʻlarynxʼ (plural ʻlaryngesʼ) comes from the Ancient Greek word ''lárunx'' ʻlarynx, gullet, throat.ʼ Structure The triangle-shaped larynx consists largely of cartilages that are attached to one another, and to surrounding structures, by muscles or by fibrous and elastic tissue components. The larynx is lined by a ciliated columnar epithelium except for the vocal folds. The cavity of the larynx extends from its triangle-shaped inlet, to the epiglottis, and to the circular outlet at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannula
A cannula (; Latin meaning 'little reed'; plural or ) is a tube that can be inserted into the body, often for the delivery or removal of fluid or for the gathering of samples. In simple terms, a cannula can surround the inner or outer surfaces of a trocar needle thus extending the effective needle length by at least half the length of the original needle. Its size mainly ranges from 14 to 24 gauge. Different-sized cannula have different colours as coded. Decannulation is the permanent removal of a cannula ( extubation), especially of a tracheostomy cannula, once a physician determines it is no longer needed for breathing. Medicine Cannulas normally come with a trocar inside. The trocar is a needle, which punctures the body in order to get into the intended space. Many types of cannulas exist: Intravenous cannulas are the most common in hospital use. A variety of cannulas are used to establish cardiopulmonary bypass in cardiac surgery. A nasal cannula is a piece of plastic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superficial Vein
Superficial veins are veins that are close to the surface of the body, as opposed to deep veins, which are far from the surface. Superficial veins are not paired with an artery, unlike the deep veins, which are typically associated with an artery of the same name. Superficial veins are important physiologically for cooling of the body. When the body is too hot, the body shunts blood from the deep veins to the superficial veins to facilitate heat transfer to the body's surroundings. Superficial veins are often visible underneath the skin. Those below the level of the heart tend to bulge out, which can be readily witnessed in the hand, where the veins bulge significantly less after the arm has been raised above the head for a short time. Veins become more visually prominent when lifting heavy weight, especially after a period of proper strength training. Physiologically, the superficial veins are not as important as the deep veins (as they carry less blood) and are sometime ...

Sir Benjamin Collins Brodie, 1st Baronet
Sir Benjamin Collins Brodie, 1st Baronet, (9 June 178321 October 1862) was an English physiologist and surgeon who pioneered research into bone and joint disease. Biography Brodie was born in Winterslow, Wiltshire. He received his early education from his father, the Rev Peter Bellinger Brodie; then choosing medicine as his profession he went to London in 1801 and attended the lectures of John Abernethy and attended Charterhouse School. Two years later he became a pupil of Sir Everard Home at St George's Hospital, and in 1808 was appointed assistant surgeon at that institution, on the staff of which he served for over thirty years. In 1810 he was elected a fellow of the Royal Society, to which in the next four or five years he contributed several papers describing original investigations in physiology. In 1834, he was elected a foreign member of the Royal Swedish Academy of Sciences. At this period he also rapidly obtained a large and lucrative practice and from time to t ...

Brodie–Trendelenburg Percussion Test
The Brodie–Trendelenburg percussion test is a medical test to determine valvular incompetence in superficial veins. A finger is placed over the lower (distal) part of the vein being examined. The upper (proximal) part of the vein is then tapped (percussed). If the impulse is felt by the finger placed at the lower end, it indicates incompetence of valves in that vein. The test is used as part of the examination of varicose veins. It is named after Sir Benjamin Collins Brodie and Friedrich Trendelenburg Friedrich Trendelenburg (; 24 May 184415 December 1924) was a German surgeon.
