Anatomy Flashcards
Is palpable within the jugular notch.
Trachea
Is the level at which the lower respiratory tract begins.
C6 vertebra
Is an anatomical landmark for cardiopulmonary resuscitation
Xiphoid process
Contains hyaline cartilage, and is surrounded by the arch of the azygous vein.
Right main bronchus
Carry oxygenated blood, and are sited inferoposteriorly within the lung root.
Pulmonary vein
Carry deoxygenated blood, and are sited superomedially within the lung root.
Pulmonary artery
Carries deoxygenated blood, drains into the superior vena cava and arches round the right lung root.
Azygous vein
Arise from the anterior surface of the descending aorta.
Bronchial arteries
Surrounded by vessels, and may appear black on dissection.
Pulmonary lymph nodes
Where the middle lobe is auscultated.
Between right ribs 4 and 6
The site of the lung apex.
Superior to the clavicle
Where the lung base is auscultated.
T11 vertebra
The site of the horizontal fissure.
T11 vertebra
The level of the carina
Rib 2
The level of the oblique fissure posteriorly.
T3 vertebra
Is a palpable reference point that can be used in basic emergency care.
Xiphoid process
The site used in decompressing a tension pneumothorax.
2nd intercostal space
The site of the oblique fissure anteriorly.
Rib 6
An accessory muscle of respiration in the neck
Sternocleidomastoid
A major inspiratory muscle in a sheet, containing crura.
Diaphragm
Thoracic muscles involved in active expiration.
Internal intercostals
Function of Intercostal nerves
Provides motor innervation to the intercostal muscles and anterolateral abdominal wall muscles
Function of Vagus nerve (CN X)
Provides motor innervation to the soft palate and intrinsic laryngeal muscles
Function of Glossopharyngeal nerve (CN IX) and vagus nerve (CN X)
Stimulation triggers a reflex cough response
Function of Glossopharyngeal nerve (CN IX) and trigeminal nerve (CN V)
Stimulation triggers a reflex sneeze response
Trigeminal nerve (CN V)
Provides sensory innervation to the nasal mucosa and motor innervation to the soft palate
Thoracoabdominal nerves
Innervate the abdominal wall with somatic sensory, somatic motor and sympathetic nerve supply
Phrenic nerves
Provides motor innervation to the diaphragm
Thoracoabdominal nerves
Innervate the abdominal wall with somatic sensory, somatic motor and sympathetic nerve supply
Intercostal nerves
Provides motor innervation to the intercostal muscles and anterolateral abdominal wall muscles
