Depends on whether it's a partial paralysis or complete. e.g Unilateral diaphramatic paralysis is where only one side of the diaphgram has stopped moving with breathing, Bilateral is where both sides of the diaphragm stop. Unilateral paralysis is common in injury to the chest or after sugery to the chest region and even in someone who has had a sport related injury or similar, and does lead to shortness of breath on excercise, possible heart attack like pains, sometimes severe acid reflux from the stomach as the stomach often moves up into the chest cavity due to the space left by the relaxed diaphragm. I know these symptons, I have had many visits to hospital due to severe chest pains, which, as you can imagine, must be checked out in case it is really a heart attack. I have lost 20-25% of my breathing capacity. Bilateral paralysis is far more serious leading to the body unable to absorb enough oxygen due to impaired lung function and most cases need hospital care and in both cases unilateral and bilateral, an operation can be performed with varying degrees of success. Hope this answers your question, regards Colin
What else can I help you with?
Which of these are tissues that can relax and contract?
Smooth muscle tissues can relax and contract. Additionally, cardiac muscle tissues also have the ability to relax and contract. Skeletal muscle tissues are another type that can relax and contract voluntarily.
Is the exchange of air between the human body and the environment the result of coordinated contractions of the muscles of the rib cage and the lungs?
Yes, the exchange of air between the human body and the environment involves the coordinated contractions of the muscles of the rib cage and the diaphragm, which help expand and contract the lungs. When we inhale, the diaphragm and intercostal muscles contract to expand the thoracic cavity, allowing air to be drawn into the lungs. When we exhale, the diaphragm and intercostal muscles relax, causing the thoracic cavity to decrease in size and push air out of the lungs.
What stimulates diaphragm?
The diaphragm is primarily stimulated to contract by the phrenic nerves, which originate from the spinal cord. The phrenic nerves send signals to the diaphragm to contract and initiate breathing. Additionally, chemical factors like excess CO2 levels in the blood can also stimulate the diaphragm to increase breathing rate.
Which ecg wave must occur before the ventricles can relax?
The T wave on an ECG must occur before the ventricles can relax. This wave represents the repolarization of the ventricles, signifying that they have finished contracting and are now primed for relaxation.
During eupnea, which muscles contract to facilitate expiration?
During eupnea, the diaphragm and external intercostal muscles contract to facilitate expiration.
What happen to diaphragm when you relax?
It becomes domed.
What stimulates the diaphragm?
The diaphragm is stimulated to contract and relax by the phrenic nerve, which originates from the cervical spine. This nerve sends signals to the diaphragm to contract, allowing it to move downward and create negative pressure in the chest cavity for inhalation, and then to relax for exhalation.
Does diaphragm have any desiesses?
Yes, the diaphragm can be affected by disorders or conditions such as paralysis, diaphragmatic hernia, or diaphragm muscle weakness. These conditions can impact the ability of the diaphragm to properly contract and relax, leading to difficulties in breathing and other respiratory functions.
How and why air moves into and out of lungs when you inhale and exhale?
When you breathe in, your diaphragm will contract, causing your lungs to expand and suck in air. When you breathe out, your diaphragm will relax, causing your lungs to shrink and force out air.
What muscle contract during inhalation and what muscles contract during exhalation?
The intercostal muscles, (muscles between the ribs), contract.
When the quadriceps contract what also must happen at the same time?
The hamstrings must relax.
Does exhalation occur when the diaphragm and rib cage muscles relax?
Yes, exhalation occurs when the diaphragm and muscles of the rib cage relax.
What do you think will happen if the diaphragm cannot control an relax?
It can be a symptom of various illnesses such as emphysema. It is uncomfortable, even painful, but you can live with it OK.
How do muscles contract and relax?
muscles contract and relax by bring about movements.
What tighten and get shorter when you inhale but relax and get longer when you exhale?
The diaphragm and intercostal muscles tighten and contract during inhalation, causing the rib cage to lift and expand, resulting in a shorter length. During exhalation, these muscles relax, allowing the rib cage to lower and return to its longer length.
What happens to your diaphragm when you relax?
It becomes domed.
What two ways do muscles work?
They contract and relax
