Broadbent Sign
Broadbent sign is a medical sign, clinical sign in which the 11th and 12th ribs are indrawn during systolic phase of a heartbeat, with narrowing of the intercostal space posteriorly, which is seen in case adhesive pericarditis due to Pericardium, pericardial adhesions to the Thoracic diaphragm, diaphragm. During diseased status of adhesive pericarditis, the pericardium of the heart may adhere not only to the central tendon of diaphragm, but also to a large area of muscular portion of Thoracic diaphragm, diaphragm as well as anterior chest wall. Thus when the heart contracts, the adhesion portion may be dragged inward and downward (if the main contraction force is toward central tendon of diaphragm). Besides, absent palpable apical impulse can also be detected in the case of adhesive pericarditis. The sign is named after Walter Broadbent, and was published in his first paper in 1895, although it may have been inspired by his father, William Broadbent, Sir William Broadbent.Barry G. ...

Medical Sign
Signs and symptoms are the observed or detectable signs, and experienced symptoms of an illness, injury, or condition. A sign for example may be a higher or lower temperature than normal, raised or lowered blood pressure or an abnormality showing on a medical scan. A symptom is something out of the ordinary that is experienced by an individual such as feeling feverish, a headache or other pain or pains in the body. Signs and symptoms Signs A medical sign is an objective observable indication of a disease, injury, or abnormal physiological state that may be detected during a physical examination, examining the patient history, or diagnostic procedure. These signs are visible or otherwise detectable such as a rash or bruise. Medical signs, along with symptoms, assist in formulating diagnostic hypothesis. Examples of signs include elevated blood pressure, nail clubbing of the fingernails or toenails, staggering gait, and arcus senilis and arcus juvenilis of the eyes. Indicati ...

Intercostal Space
The intercostal space (ICS) is the anatomic space between two ribs (Lat. costa). Since there are 12 ribs on each side, there are 11 intercostal spaces, each numbered for the rib superior to it. Structures in intercostal space * several kinds of intercostal muscle * intercostal arteries and intercostal veins * intercostal lymph nodes * intercostal nerves Order of components Muscles There are 3 muscular layers in each intercostal space, consisting of the external intercostal muscle, the internal intercostal muscle, and the thinner innermost intercostal muscle. These muscles help to move the ribs during breathing. Neurovascular bundles Neurovascular bundles are located between the internal intercostal muscle and the innermost intercostal muscle. The neurovascular bundle has a strict order of vein-artery- nerve (VAN), from top to bottom. This neurovascular bundle runs high in the intercostal space, and the smaller collateral neurovascular bundle runs just superior ...

Adhesive Pericarditis
Adhesive, also known as glue, cement, mucilage, or paste, is any non-metallic substance applied to one or both surfaces of two separate items that binds them together and resists their separation. The use of adhesives offers certain advantages over other binding techniques such as sewing, mechanical fastenings, or welding. These include the ability to bind different materials together, the more efficient distribution of stress across a joint, the cost-effectiveness of an easily mechanized process, and greater flexibility in design. Disadvantages of adhesive use include decreased stability at high temperatures, relative weakness in bonding large objects with a small bonding surface area, and greater difficulty in separating objects during testing. Adhesives are typically organized by the method of adhesion followed by ''reactive'' or ''non-reactive'', a term which refers to whether the adhesive chemically reacts in order to harden. Alternatively, they can be organized eit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pericardium
The pericardium, also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. It has two layers, an outer layer made of strong connective tissue (fibrous pericardium), and an inner layer made of serous membrane (serous pericardium). It encloses the pericardial cavity, which contains pericardial fluid, and defines the middle mediastinum. It separates the heart from interference of other structures, protects it against infection and blunt trauma, and lubricates the heart's movements. The English name originates from the Ancient Greek prefix "''peri-''" (περί; "around") and the suffix "''-cardion''" (κάρδιον; "heart"). Anatomy The pericardium is a tough fibroelastic sac which covers the heart from all sides except at the cardiac root (where the great vessels join the heart) and the bottom (where only the serous pericardium exists to cover the upper surface of the central tendon of diaphragm). The fibrous pericardiu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thoracic Diaphragm
The thoracic diaphragm, or simply the diaphragm ( grc, διάφραγμα, diáphragma, partition), is a sheet of internal Skeletal striated muscle, skeletal muscle in humans and other mammals that extends across the bottom of the thoracic cavity. The diaphragm is the most important Muscles of respiration, muscle of respiration, and separates the thoracic cavity, containing the heart and lungs, from the abdominal cavity: as the diaphragm contracts, the volume of the thoracic cavity increases, creating a negative pressure there, which draws air into the lungs. Its high oxygen consumption is noted by the many mitochondria and capillaries present; more than in any other skeletal muscle. The term ''diaphragm'' in anatomy, created by Gerard of Cremona, can refer to other flat structures such as the urogenital diaphragm or Pelvic floor, pelvic diaphragm, but "the diaphragm" generally refers to the thoracic diaphragm. In humans, the diaphragm is slightly asymmetric—its right half is h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Tendon Of Diaphragm
The central tendon of the diaphragm is a thin but strong aponeurosis situated slightly anterior to the vault formed by the muscle, resulting in longer posterior muscle fibers. It is inferior to the fibrous pericardium, which fuses with the central tendon of the diaphragm via the pericardiacophrenic ligament. The caval opening (at the level of the T8 vertebra) passes through the central tendon. This transmits the inferior vena cava and right phrenic nerve. Structure The central tendon is shaped somewhat like a trefoil leaf, consisting of three divisions or leaflets separated from one another by slight indentations. The right leaflet is the largest, the middle (directed toward the xiphoid process) the next in size, and the left the smallest. The central tendon is composed of several planes of fibers, which intersect one another at various angles and unite into straight or curved bundles—an arrangement which gives it additional strength.

William Broadbent
Sir William Henry Broadbent, 1st Baronet (23 January 1835 – 10 July 1907) was an English neurologist who was a leading British authority in the field of cardiology as well as neurology. He also performed research involving diseases such as tuberculosis and cancer. In 1881 he was elected President of the London Medical Society and in 1887 President of the Clinical Society of London. Broadbent was a Physician-Extraordinary to Queen Victoria and Physician-in-Ordinary to King Edward VII and the Prince of Wales. Early life and education Broadbent was born at Longwood Edge in Lindley, now part of Huddersfield, West Yorkshire. He was the eldest of seven children born to John Broadbent, a wool manufacturer and prominent Wesleyan, and Esther (''née'' Butterworth). His younger brother was Colonel John Edward Broadbent . He was educated at Huddersfield College before he decided to study medicine. He was apprenticed to a doctor in Manchester before studying medicine at Owens Colleg ...
