Term
Inhalation (Inspiration)
Definition
This pattern expands the chest cavity where oxygen is brought to the blood and air is drawn into the lungs.
Term
Exhalation (Expiration)
Definition
This pattern helps get rid of mixed air and gases. The muscles contract to reduce the volume of the chest cavity, creating a positive pressure within the lungs.
Term
Lungs
Definition
These organs are located in the thoracic cavity and take up most of the cavity's space. One is bigger than the other because the liver is located directly underneath it.
Term
Bronchi
Definition
Tubes that extend from the lungs upward to the trachea. They are composed of cartilaginous rings bound together by fibroelastic tissue.
Term
Bronchioles
Definition
Less cartilaginous than the bronchi; however are more muscular in composition. They communicate with alveolar ducts that open into tiny air sacs.
Term
Trachea
Definition
A tube formed by approximately 20 rings of cartilage. This structure comes into direct contact with the esophagus, it connects to the inferior border of the cricoid cartilage.
Term
Spinal column
Definition
Vertebrae that are divided into 5 segments. Cervical, thoracic, lumbar, sacral, and coccygeal.
Term
Sternum (breastbone)
Definition
This structure consists of 3 parts: Manubrium, body, and xiphoid process.
Term
Manubrium
Definition
Uppermost segment of the sternum and provides the attachment for the clavicle and the first rib.
Term
Corpus (body)
Definition
Is a long and narrow segment of the sternum. Cartilages of ribs 2 through 7 attach here.
Term
Xiphoid Process
Definition
A small cartilagious structure found at the bottom of the body of the sternum.
Term
Thoracic cage
Definition
Usually called the chest and consists of 12 pairs of ribs that form a cyndrical structure.
Term
Thoracic Muscles of Inspiration
Definition
Diaphragm, abdomen, and intercostal muscles.
Term
Diaphragm
Definition
A thick, dome-shaped muscle that separates the abdomen from the thorax. It also distends abdomen, enlarges vertical dimension of thorax, and depresses central tendon.
Term
Abdomen
Definition
Houses structures such as the intestines, liver, and kidneys. Critical in providing support for breathing.
Term
Internal intercostal muscles
Definition
pull the ribs downward to decrease the diameter of the thoracic cavity for exhalation.
Term
External intercostal muscles
Definition
raise the ribs up and out to increase the diameter of the thoracic cavity for inhalation.
Term
Muscles that help elevate the rib cage.
Definition
Serratus posterior superior, levator costarum brevis, levator costarum longis, and external intercostals.
Term
Sternocleidomastoid
Definition
Elevates the sternum and indirectly the rib cage.
Term
Trapezius
Definition
Controls the head and elongates the neck, thus indirectly influencing respiration.
Term
Muscles which increase or decrease the dimension of the rib cage.
Definition
Pectoralis major, pectoralis minor, serratus anterior, and levator scapulae.
Term
Subcostal muscle
Definition
depresses the thorax.
Term
Serratus Posterior Inferior muscles
Definition
When contracted, pull the rib cage down and thus aid in exhalation.
Term
Abdominal muscles of Expiration
Definition
Latissimus dorsi, rectus abdominis, transverse abdominis, internal oblique abdominis, and quadratus lumborum.
