In human investigations, changes in cochlear blood flow were demonstrated with direct electrical stimulation of the round window and warm water irrigation of the ear canal, but not with carbogen breathing. Increased cochlear blood flow was observed with increased systemic blood pressure, and a ...
arteria basilaris, basilar artery - an unpaired artery; supplies the pons and cerebellum and the back part of the cerebrum and the inner ear arteria brachialis, brachial artery - the main artery of the upper arm; a continuation of the axillary artery; bifurcates into the radial and ulnar art...
Together, the colon, rectum, anal canal, and anus form a long (several feet in length), muscular tube that also is known as the large intestine, large bowel, or the lower gastrointestinal tract. The colon can be divided further into three regions; the right colon, the transverse colon, ...
Marrow of long bones receives part of its blood supply from the nutrient artery, which enters the bone via the nutrient canal at midshaft. The remaining arterial supply enters the marrow through an anastomosing array of vessels that arise from the periosteal arteries and penetrate the cortical ...
Now, at the insertion site, hold the lancet perpendicular to the skin surface with the tip facing slightly toward the nose. This is critical, because if the lancet tip is directed caudally, the ear canal will be pierced causing bleeding from the ear. To puncture the vein, apply a firm ...
SOLUTION: A mounting part 3 is formed as an integrated member 50 integrally or individually provided with a shape part 52 to be filled in a space part from the ear concha to the antihelix, a first projection part 54 extended from the shape part toward an external auditory canal, a second...
Inner ear disorders are a cluster of diseases that cause hearing loss in more than 1.5 billion people worldwide. However, the presence of the blood-labyrinth barrier (BLB) on the surface of the inner ear capillaries greatly hinders the effectiveness of s
Dyslipidemia is the primary cause of cardiovascular disease, which is a serious human health problem in large parts of the world. Therefore, it is important to understand the genetic and molecular mechanisms that regulate blood levels of cholesterol and
The first two ventricles are a pair of C-shaped lateral ventricles, one in each cerebral hemisphere. Each of these communicates through a small pore with a slitlike third ventricle between the two hemispheres, surrounded by the diencephalon. From here, a slender canal, the cerebral aqueduct, ...
The guinea pig model was used because of its extensive use for study of inner ear function, including inner ear blood flow.7, 15, 16, 17, 18, 19 The well-established technique of laser Doppler flowmetry provided continuous in vivo measures of VBF. The posterior semicircular canal ampulla ...
