In a linear system, "flutter point" is the point at which the structure is undergoing simple harmonic motion—zero net damping—and so any further decrease in net damping will result in a self-oscillation and eventual failure. "Net damping" can be understood as the sum of the structure's natural positive damping and the negative damping of ...
The concern about "mediastinal flutter" (the shift of the mediastinum with paradoxical diaphragm movement) does not appear to be merited. [8] Pulmonary contusions are commonly associated with flail chest and that can lead to respiratory failure. This is due to the paradoxical motions of the chest wall from the fragments interrupting normal ...
[65] [66] Anatomy advanced further with the invention of the microscope and the study of the cellular structure of tissues and organs. [67] Modern anatomy uses techniques such as magnetic resonance imaging , computed tomography , fluoroscopy and ultrasound imaging to study the body in unprecedented detail.
Superficial anatomy of female and male human body Surface projections of the major organs of the trunk, using the vertebral column and rib cage as main reference points of superficial anatomy Surface anatomy , or superficial anatomy, is the study of anatomical landmarks that can be identified readily from the contours or other reference points ...
Myofascial trigger points (MTrPs), also known as trigger points, are described as hyperirritable spots in the skeletal muscle. They are associated with palpable nodules in taut bands of muscle fibers. [1] They are a topic of ongoing controversy, as there is limited data to inform a scientific understanding of the phenomenon.
They are often described as a skipped beat, a rapid flutter, or a pounding in the chest or neck. [1] [2] Palpitations are not always the result of a physical problem with the heart and can be linked to anxiety. [3] However, they may signal a fast or irregular heartbeat. Palpitations can be brief or long-lasting. They can be intermittent or ...
Human anatomy is the scientific study of the morphology of the adult human. It is subdivided into gross anatomy and microscopic anatomy . Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision.
On the trunk of the body, the chest is referred to as the thoracic area. The shoulder in general is the acromial, while the curve of the shoulder is the deltoid.
