Carotid Sinus Syncope is a form of syncope associated with external pressure being applied to the carotid sinus. It is commonly subdivided into cardioinhibitory (heart rate affected) and baroreceptor(blood pressure affected), which have different treatments, although often can be both cardioinhibitory and baroreceptor (mixed) type. It may occur on just turning the head in some people. Other related archivescarotid sinus, syncope

A sinus is a pouch or cavity in any organ or tissue, or an abnormal cavity or passage caused by the destruction of tissue. The term is applied to a large number and variety of structures in animals, such as:- The air cavities in the cranial bones, especially those near the nose and connecting to it. These are the paranasal sinuses and are usually what is meant when a person's "sinuses" are referred to. A dilated portion of a blood vein, such as inside the braincase. A chronically infected tract such as a fistula. Another name for the hemocoel, a space in organisms with open circu ...

'Aneurysm of the aortic sinus', also known as the sinus of Valsalva, is comparatively rare, occurring in about one person in every thousand. When present, it is usually in either the right (65-85%) or in the noncoronary (10-30%) sinus, rarely in the left (< 5%) sinus. This type of aneurysm is typically congenital and may be associated with heart defects. It is sometimes associated with Marfan syndrome, but may also result from Ehlers-Danlos syndrome, atherosclerosis, syphil ...

Carotid sinus reflex death has an entirely plausible mechanism, and may not be rare. The carotid sinus nerve complex at the branching of each carotid artery to the internal and external carotid arteries, on each side of the neck under the jaw, is strongly associated with the vagus nerve. Massage of this area is used clinically to slow the heart rate in conditions of dangerous rapid pulse, such as paroxysmal atrial tachycardia (see supraventricular tachycardia), a common presentation in the emergency department. Rubbing of this part of ...

An aortic aneurysm is a general term for any swelling (dilatation or aneurysm) of the aorta, usually representing an underlying weakness in the wall of the aorta at that location. While the stretched vessel may occasionally cause discomfort, it is the risk of rupture causing severe pain, massive internal hemorrhage and, without prompt treatment, resulting in a quick death. In addition the aneurysm may split (Aortic dissection) which may block vessels that branch off from the aorta or release blood clots (emboli) causing ...

A headache (medically known as cephalgia) is a condition of mild to severe pain in the head; sometimes upper back or neck pain may also be interpreted as a headache. Headache is the second-most common form of local pain. (The most common is molar pain, i.e. toothache in one or more of the flat-crowned teeth used for grinding food.) Headaches have a wide variety of causes, ranging from eyestrain to inflammation of the sinus cavities to life-threatening conditions such as encephalitis, brain cancer, meningitis, and cerebra ...

Vasomotor rhinitis is a form of rhinitis that is not related to allergic reactions, but which is characterized by many of the same symptoms, such as a chronic running nose with intermittent sneezing, rhinorrhea and blood-vessel congestion of the nasal mucus membranes. Vasomotor rhinitis is to be distinguished from sinus infection or other forms of allergy. Vasomotor rhinitis - Causes. Vasomotor rhinitis is also known as non-allergenic rhinitis, because it often has the same symptoms as allergies, but has di ...

Wasabi (Japanese: 山葵 or 和佐比; Wasabia japonica, Cochlearia wasabi, or Eutrema japonica) is a member of the cabbage family. Known as Japanese horseradish, its root is used as a spice and has an extremely strong flavor. Its hotness is different from that of the chile pepper, which burns the tongue; wasabi produces vapors that burn the sinus cavity instead. The plant grows naturally along stream beds in mountain river valleys in Japan. There are also other species used, such as W. koreana, and W. t ...

Airy-0 is a crater on Mars whose location defines the position of the prime meridian of that planet. Airy-0 is about 0.5 kilometers across and lies within the larger crater Airy in the region Sinus Meridiani. Airy crater was named in honor of the British Astronomer Royal Sir George Biddell Airy (1801-1892), who in 1850 built the "transit circle" telescope at Greenwich. The location of that telescope was subsequently chosen to d ...

The Vaquita (Phocoena sinus) is a rare species of porpoise. It is endemic to the northern part of the Gulf of California (Sea of Cortez). Estimates of the number of individuals alive range from 100 [1][2] to 300 [2] making it amongst the most endangered of all marine mammals [1]. The word "vaquita" is Spanish for little cow. Other names include Cochito, Gulf of California Harbor Porpoise, Gulf of California Porpoise, Gulf Porpoise, Hafensch ...

Sick sinus syndrome is a relatively uncommon syndrome. It can result in many abnormal heart rhthyms (arrhythmias), including sinus arrest, sinus node exit block, sinus bradycardia, and other types of bradycardia (slow heart rate). Sick sinus syndrome may also be associated with tachycardias (fast heart rate) such as PSVT and atrial fibrillation. Tachycardias that occur with sick sinus syndrome are charac ...

Maxilla - Anterior surface. The anterior surface [Fig. 1] is directed forward and lateralward. It presents at its lower part a series of eminences corresponding to the positions of the roots of the teeth. Just above those of the incisor teeth is a depression, the incisive fossa, which gives origin to the Depressor alae nasi; to the alveolar border below the fossa is attached a slip of the Orbicularis oris; above and a littl ...

('sinus maxillaris') The maxillary sinus is a large pyramidal cavity, within the body of the maxilla: its apex, directed lateralward, is formed by the zygomatic process; its base, directed medialward, by the lateral wall of the nose. Its walls are everywhere exceedingly thin, and correspond to the nasal orbital, anterior, and infratemporal surfaces of the body of the bone. Its nasal wall, or base, presents, in the disarticulated bone, ...

At birth the transverse and antero-posterior diameters of the bone are each greater than the vertical. The frontal process is well-marked and the body of the bone consists of little more than the alveolar process, the teeth sockets reaching almost to the floor of the orbit. The maxillary sinus presents the appearance of a furrow on the lateral wall of the nose. In the adult the vertical diameter is the greatest, owing to the developm ...

The maxilla is ossified in membrane. Mall 40 and Fawcett 41 maintain that it is ossified from two centers only, one for the maxilla proper and one for the premaxilla. These centers appear during the sixth week of fetal life and unite in the beginning of the third month, but the suture between the two portions persists on the palate until nearly middle life. Mall states that the frontal process is developed from both centers. The maxillary sinus appears as a shallow groove on the nasal surface of the bone about the fourth month of fetal life, but does not reach its ful ...

A related set of features are the sinus (singular sinus, Latin for "bay") and paludes (singular palus, Latin for "marsh"): Some sources also list a Palus Nebularum ("Marsh of Mists") at 38.0° N, 1.0° E. However the designation for this feature has not been officially recognized by the IAU. ...

Maxilla - The zygomatic process. ('processus zygomaticus; malar process') The zygomatic process is a rough triangular eminence, situated at the angle of separation of the anterior, zygomatic, and orbital surfaces. In front it forms part of the anterior surface; behind, it is concave, and forms part of the infratemporal fossa; above, it is rough and serrated for articulation with the zygomatic bone; while below, it presents the prominent arched border which marks the division between the anterior and infratemporal surfaces. ...

Along the periphery of the mare are several bay-shaped features that have been given names. Mare Tranquillitatis - Sinus Amoris. The "Bay of Love" extends northward from the northeast end of the Mare Tranquillitatis. It is located at selenographic coordinates 18.1° N, 39.1° E, and lies within a diameter of 130 km. To the north of the bay are the jumbled Montes Taurus peaks. Near the southern end of the bay where it outlets into the Mare Tranquillitatis lies the Theophrastus crater. Along the weste ...
