Position of;
Intercostals.. In-between the ribs, running obliquely downwards
Diaphragm.. Mid chest separating the thoratic and abdominal cavities.
Action;
..Keeps us breathing when working with the ribs, sternum and lungs.
..expands and retracts with breathing

∙ 10y agoVentilation of the lungs is the process of which air is inhaled into and exhaled out of the lungs. This process is the first stage in respiration.
*Costal breathing- a pattern of shallow (chest) breathing consisting of an upward and outward movement of the chest due to contraction of the external intercostals muscles.
*Diaphragmatic breathing- a pattern of deep (abdominal) breathings consisting of the outward movement of the abdomen due to the contraction and descent of the diaphragm.

∙ 11y agoAs the diaphragm contracts, the intercostal muscles pull the ribs up and out, thereby increasing the volume of the thoracic cavity. This allows us to inhale.

What are the classification of muscles according to action?
prime movers : muscle that initiate a particular movement synergism : muscles that have the same action of the prime mover antagonist : muscles that come into play to oppose a certain movement
Which describes the action of the diaphragm and chest cavity when you exhale and squeeze air from the lungs?
it will changes the air pressure in the thoratic cavity by increasing or decreasing the thoratic volume
What is the action of calcaneal tendon?
The action of the calcaneal tendon is to allow your soleus and gastrocnemius muscles to (plantar) flex your foot.
Does adduction require the action of two muscles?
the moving and taking away from your body i.e. adduction is moving your arm towards your body again and abduction is when you move your arm away from you
The action that moves the palm of the hand into anatomical position is what?
supination
How does the action of the external intercostal and diaphragm muscles draw air up your nose?
External intercostal and diaphragm increase the volume of the lungs, this action dicreases the pressure of the lungs. (we know pressure moves from the region of higher region to lower, in this case pressure is high in atmosphere and low in lungs). So air gets drew up in our nose.
Describe the muscle activity involved in normal relaxed breathing?
Normal relaxed breathing is referred to as tidal volume. This is produced by the action of the diaphragm muscle only. It is also referred to as diaphragmatic breathing and is associated with a relaxed state.
What is the action of the muscles that cause air to come into the lungs?
The action is the flattening of your diaphragm, or the muscle that helps your lungs inhale and exhale.
What is the action of the muscles that causes air to come into the lungs?
The action is the flattening of your diaphragm, or the muscle that helps your lungs inhale and exhale.
What part of your lungs inflate and deflate?
Action of the diaphragm causes healthy lungs to inflate in whole like a balloon.Doctors have said that the average person does not breath properly, thereby not filling our lungs with sufficient air to help purify our blood. We should do daily exercises of deep beathing or get into the habit of breathing more deeply than we do.
Position of muscles?
There are approximately 642 skeletal muscles within the typical human, and almost refers to the action of each muscle from the standard anatomical position.
If you damaged your intercostal muscles which process would be seriously impaired?
There are three layers of intercostal muscles: the External Intercosals, the Internal Intercostals and the Innermost Intercostals. These muscles are the one found between the Ribs in the ribcage and all are innervated by coastal nerves. At rest these particular muscles have very little function it is only during Forced Respiration (forced breathing not the cellular kind of respiration) that they come into action. During Forced Inspiration the Diaphragm pulls down as normal but to maximise increase the size of the Thoracic Cavity and suck in extra air the the external intercostals are activated. These muscles pull the ribs up and forwards. During normal expiration the elasticity of the lungs themsevels as well as action from the abdominal muscles shrink the thoracic cavity pushing the used air out again. This is not fast enough however for exercising, where forced expiration is required. Here the internal and innermost intercostals pull the ribs down and back compressing the thoracic cavity and forcefull (as aposed to passively) push the air out. Damage to any layer of the intercostal muscles is likely to make breathing during exercise much harder and less efficient.
When a person exhales what happens to the diaphragm?
The diaphragm muscles contract and relax pulling the diaphragm down and then releasing it. When we inhale, our diaphragm muscles contracts and flattens. When we exhale, they relax and arch upwards.
Is hiccups using involuntary muscles?
it is an involuntary action not muscles
Which muscle under the lungs pulls down when humans breathe in?
When the lungs are expanded, this action takes place due to the diaphragm contracting during inhalation. During exhalation, the diaphragm relaxes.
How does the respiratory system helps the skeletal system?
the bones protect the lungs that breath not only that, the movement of the bones help the amount of air that can be taken in or let out during inspiration (i.e; taking air in), the ribcage moves upwards and outwards (because of the contraction of external intercostal muscles and relaxation of internal intercostal muscles), this causes the sternum (chest bone) to move up and away from the ribcage. as a result, the 'dorsoventral' diameter of the thorax (lung cavity) increases. more air can now be taken in. during expiration, the action is entirely opposite to this
How does the diaphragm affect the lungs?
The diaphragm (also called the thoracic diaphragm) is a layer of muscle extending across the bottom of the ribcage. The diaphragm separates the thoracic cavity from the abdominal cavity. A diaphragm in anatomy is generally used to describe flat structures, like the urogenital and pelvic diaphragm. However when someone speaks of "the diaphragm" they generally mean the thoracic one. With regards to respiration, the diaphragm is a crucial aspect of the process. During inhalation, the diaphragm contracts, allowing the thoracic cavity to grow (the external intercostal muscles also aid expansion) allowing the lungs to take in more air. This also decreases intra-thoracic pressure, meaning when the thoracic cavity grows it creates suction which draws air into the lungs. When the diaphragm relaxes, air is exhaled thus relaxing (opposite of contracting) the diaphragm. This entire process happens every time a breath is taken.
