The diaphragm contractions are regulated by what nerve?
The diaphragm contractions are primarily regulated by the phrenic nerve, which originates from the cervical spine (C3-C5). This nerve controls the contraction and relaxation of the diaphragm muscle, allowing for the process of breathing to occur efficiently.
Which process causes the diaphragm to move back up?
Contraction of the diaphragm muscle causes it to move back up. When the diaphragm contracts, it flattens and moves downwards, increasing the volume in the thoracic cavity. This action creates negative pressure, sucking air into the lungs.
What would cause the diaphragm to be elevated?
The diaphragm can be elevated due to conditions like diaphragmatic paralysis, abdominal distension, or elevated intra-abdominal pressure from issues like ascites or pregnancy. This elevation can impact proper lung expansion and breathing.
The minimum stimulus needed to cause a contraction is called the?
The minimum stimulus needed to cause a contraction is called the threshold stimulus. This is the minimal level of stimulation required to activate muscle fibers and initiate a contraction response.
What causes the diaphragm to contract?
enlarge
Why do people get the hickkups?
With the contraction of the diaphragm by spasm the inhaling of air is stopped suddenly the gap in the vocal cords reduce during the contraction of diaphragm which causes a hiccup and the process is repeated
Inhalation in humans is achieved by?
contraction of diaphragm and chest muscles
What results from the contraction of diaphragm and external intercostal muscles?
an exhalation
What is the sudden involuntary contraction of a diaphragm muscle?
It is called a Tracheospasm
The diaphragm contractions are regulated by what nerve?

Breathing occurs due to the contraction and relaxation of the muscles between the ribs and the?
diaphragm....
How are hiccups defined?
result of an involuntary, spasmodic contraction of the diaphragm followed by the closing of
What causes severe Hiccups in patients with temporary transvenous pacemakers?
due to contraction of the diaphragm indirectly as the electrical impulse spreads from the heart to the diaphragm.
An unpaired muscle that acts with the muscle to accomplish inspiration?
Inspiration is due to the contraction of the diaphragm and external intercostal muscles.
When the diaphragm contracts does lung volume increase or decrease?
The downward contraction of the diaphragm (below the lungs) decreases the pressure within the lungs by expanding the thoracic cavity. The lungs sag into the cavity, and outside air flows into the lungs.The contraction of the diaphragm allows the person (or animal) to inhale air. When the diaphragm relaxes, it pushes upward on the lungs and exhalation occurs.
What is the medical term meaning reflex spasm of the diaphragm?
Hiccough or Hiccup.Singultus is the medical term meaning involuntary contraction of the diaphragm. The lay term is hiccup.
What allows you to inhale and exhale?
Inhalation requires the contraction of the diaphragm, and exhalation occurs when it relaxes.
