The muscles of respiration are the muscles that contribute to inhalation and exhalation, by aiding in the expansion and contraction of the thoracic cavity. The diaphragm and, to a lesser extent, the intercostal muscles drive respiration during quiet breathing. The elasticity of these muscles is crucial to the health of the respiratory system ...
Depending on the procedure, general anaesthesia may be optional or required. Regardless of whether a patient may prefer to be unconscious or not, certain pain stimuli could result in involuntary responses from the patient (such as movement or muscle contractions) that may make an operation extremely difficult. Thus, for many procedures, general ...
Neurogenic claudication (NC), also known as pseudoclaudication, is the most common symptom of lumbar spinal stenosis (LSS) and describes intermittent leg pain from impingement of the nerves emanating from the spinal cord. [ 1 ][ 2 ]Neurogenic means that the problem originates within the nervous system. Claudication, from Latin claudicare 'to ...
Treatment. Surgery. Prognosis. 15–40% mortality rate. Diaphragmatic rupture (also called diaphragmatic injury or tear) is a tear of the diaphragm, the muscle across the bottom of the ribcage that plays a crucial role in breathing. Most commonly, acquired diaphragmatic tears result from physical trauma. Diaphragmatic rupture can result from ...
The leg press and the squat are both knee-dominant moves. Because of that, the two exercises are powered by the same major muscle groups: the quads and the glutes.
Coronary artery bypass surgery, also known as coronary artery bypass graft (CABG, pronounced "cabbage"), is a surgical procedure to treat coronary artery disease (CAD), the buildup of plaques in the arteries of the heart. It can relieve chest pain caused by CAD, slow the progression of CAD, and increase life expectancy.
Diaphragm pacing (and even earlier as electrophrenic respiration[ 1 ][ 2 ]) is the rhythmic application of electrical impulses to the diaphragm to provide artificial ventilatory support for respiratory failure or sleep apnea. [ 3 ][ 4 ] Historically, this has been accomplished through the electrical stimulation of a phrenic nerve by an ...
The phrenic nerve is a mixed motor/sensory nerve that originates from the C3-C5 spinal nerves in the neck. The nerve is important for breathing because it provides exclusive motor control of the diaphragm, the primary muscle of respiration. In humans, the right and left phrenic nerves are primarily supplied by the C4 spinal nerve, but there is ...
