The human body is divided into several cavities that help to describe the location and function of the structures located in them. The two main cavities are called the ventral (front) and dorsal (back) and these are further divided into smaller cavities. The ventral cavity is di...
Describe the typical electrical path through the heart. What clinical tool can we use to measure the electrical activity of the heart? Which wave of the EKG precedes ventricular systole? What is ventricular depolarization? Which ECG wave must occur before ventricles can relax?
As the signal continues to the ventricles, they also contract. The anatomy of the heart. What is atrial fibrillation? Atrial fibrillation or AF is a heart rhythm disorder that causes the heart to beat in an irregular and often accelerated manner. The cause is a malfunction in the electrical...
The classic description of angina is a crushing pain, heaviness or pressure that radiates across the chest, sometimes down the arm, into the neck, jaw or teeth, or into the back. It may be associated with shortness of breath,nausea,vomiting, sweating, and weakness. Many people do not use...
Physiology of the Heart :The heart is composed of the middle layer; the middle of the heart separates both parts of the heart to avoid the mix-up of the oxygenated blood and deoxygenated blood. The heart cavity is divided into four chambers composed of two a...
In the patient with AD, the size of the brain ventricles (segmented and visualised in red) is much larger than in the healthy woman (ventricles shown in green). This increase in ventricular size represents atrophy (shrinking) of the brain parenchyma, which is a typical feature of AD. Three...
Basically, an OBE is where you travel outside of your body as your spirit, there are many books written on the subject and much accounted for within this subject. I am now wondering, what is possible in this four dimensional world that has now been opened through OBE? I have read storie...
N () the fourteenth letter of English alphabet, is a vocal consonent, and, in allusion to its mode of formation, is called the dentinasal or linguanasal consonent. Its commoner sound is that heard in ran, done; but when immediately followed in the same word by the sound of g hard ...
2. Topographical versus Structural Heart A heart with two ventricles, separated by a midline muscular septum defines its classic morphologic description. Despite correct topography, no functional insight is provided to define what these three structures do. A different structural guideline has existed ...
The explanation is simple: venomous snakes are predators who have neither claws nor powerful paws; but with victims’ skeletal muscle paralysis these are not necessary because a prey is unable to breathe, escape and resist. Therefore, the breakdown of movements is the leading strategy for the ...
