Chapter 2 CHEST Flashcards
What are the sections if the chest
Bony thorax, respiratory system, and mediastinum
How many sections is chest/thorax divided into
3 sections
Parts of the sternum
Manubrium, body, and xiphoid process
Two good positioning landmarks in the chest are
Vertebra prominens and jugular notch
Parts of the Skeletal framework that make up the bony thorax
- Sternum
- 2 clavicles
- 2 scapulae
- 12 pairs if ribs
- 12 thoracic vertebrae
parts of the thoracic viscera
mediastinum and lungs
parts of the mediastinum
thymus gland, heart and great vessels, trachea and esophagus
4 divisions of the respiratory system
larynx, trachea bronchi and lungs
the cartilaginous flap that covers the larynx and trachea during the act of swallowing
epiglottis
forms the inferior and posterior wall of the larynx
cricoid cartilage
prominent anterior projection of the thyroid cartilage
laryngeal prominence
located at T4
sternal angle
located between C3 and C6
Larynx
location of the esophagus compared to the trachea
posterior. it lies behind it
two parts of the bony thorax
skeletal (framework), thoracic viscera
exchange of gaseous substances between the air we breathe and the bloodstream
respiration
a passageway for both food and air.
pharynx
parts of the pharynx
oropharynx, nasopharynx,laryngopharynx
mouth to uvula
oropharynx
nose to epiglottis
nasopharynx
lies above and posterior to the larynx
laryngopharynx
makes up the roof of the mouth
the hard plate, soft plate, and uvula
also known as the windpipe
trachea
located from C6-T4
trachea
a fibrous muscular tube with about 20 c-shaped rings embedded in the walls. the rings keep the tube from collapsing during inspiration
trachea
located near the trachea, within the mediastinum, but not part of the respiratory system
thyroid, parathyroid and thymus
gland that releases hormones for regulation of body metabolism, body growth, development and activity of the nervous system
thyroid gland
