Explanation:
Doppler Echocardiogram
A traditional echocardiogram uses sound waves to produce images of the heart. In this procedure, a radiologist uses a transducer to transmit and receive ultrasound waves, which are reflected when they reach the edge of two structures with different densities. The image produced by an echocardiogram shows the edges of heart structures, but it cannot measure the speed of blood flowing through the heart. Doppler techniques must be incorporated to provide this additional information. In a Doppler echocardiogram, sound waves of a certain frequency are transmitted into the heart. The sound waves bounce off blood cells moving through the heart and blood vessels. The movement of these cells, either toward or away from the transmitted waves, results in a frequency shift that can be measured. This helps cardiologists determine the speed and direction of blood flow in the heart.
Answer:
A translation of an academic transcript should be a word-for-word rendering of the document from one language into another. A translation is distinct from a credential evaluation. An evaluation explains the meaning of the transcript.

Answer:
The function of the physis or growth plate is to allow the growth in length of the bones (both long as short) through the endochondral ossification process.
Explanation:
The epiphyseal plates are areas of active growth of new bone at the ends of the bones, made up of cartilage that hardens once the child is fully developed. Epiphyseal plates help determine the length and shape of the adult bone eventually. It is the last part of the bones to harden, and therefore they are vulnerable to fractures. The complication of the involvement of the growth plate is the deformity or lack of growth of the bone, leaving the limb twisted or shorter than the contralateral one.Growth disturbances are more frequent when the affected area is very large or when it involves the area of the knee joint. In cases of shoulder or wrist involvement, deformities rarely occur. The alterations are more common when the lesions occur in younger children, because they have a longer growth period.
Answer:
general or special
Explanation:
Sensory receptors are usually neurons cells that detect and react to physical or chemical stimuli. The sensory receptors are the starting point of information flow in nervous system. The receive a stimuli and convert to electric impulse. According to their function the sensory receptors may be divided into following categories.
General receptors are those which are not specified to specific organ and found in various organs and produce a general sense. such as mechanoreceptors which are found in wall of blood, skin and muscles. Somatosensation is considered as general sense that detect the touch, vibration, temperature etc.
Special receptors are those which are found in specific organ and contribute to specific sense such as baroreceptors found in blood vessels and photoreceptors that are majorly found in eye.
