What is the clinical significance of the sternal angle?
Sternal angle-manubriosternal joint-anterior angle formed by junction of manubrium and body of sternum-approximately 140 degreesignificant because:it lies just anterior to arch of aorta -marks the starting and ending of the aortic archanterior to the Corina (point of bifurcation of trachea into 2 main bronchi)It corresponds to the invertebral disc between T4 and T5 vertebraat the level of second pair of coastal cartilagemark superior boundary of inferior mediastinum
What are the structure at the level of the sternal angle?
Bifurcation of trachea, start and finish of the aortic arch, arch of azygos vein, 2nd costal cartilages, intervertebral disc between T4 and T5. It also separates the superior mediastinium from the inferior mediastinium.
What is the vertebral level of the bifurcation of the common carotid artery?
The bifurcation (splitting) of the common carotid artery is in line with/at the level of the intervertebral disc between the third and fourth cervical vertebral (between C3 and C4).
The inferior angle of the scapula is at the same level as the spinous process of which vertebrae?
t8 68% of people have their lower (inferior) angle of the scapula at the level of T7-T9. So the mid point of this is naturally T8 but there is some variation.
Where is the Carina located in the human body?
The carina lies at the tracheal area of the human body . The ridge lies to the left of the midline and objects s that go through the trachea are likely to enter the right bronchus. The mucous membrane of the carina is the most sensitive area of the trachea and larynx.
What are the structures that pass through the sternal angle?
The structures that pass through the sternal angle, also known as the angle of Louis, include the aortic arch, the trachea, the thoracic duct, and the ligamentum arteriosum. This anatomical landmark is important for identifying the level of the second rib and the intervertebral disc between T4 and T5.
What side of the body is the aorta on?
The Arch of Aorta is located at the level of the Sternal Angle, (LIV / LV level). From there, the descending aorta forms a groove on the left lung and continues down the left side of the body.
What is the clinical significance of the sternal angle?

What two points are used to measure jugular venous pressure?
The sternal angle and the right atrium are typically used to measure jugular venous pressure by observing the level of jugular venous distention during physical examination. The sternal angle is used as a reference point on the chest for measuring central venous pressure.
What is level of sternal notch?
The sternal notch, also known as the jugular notch, is located at the superior border of the manubrium of the sternum, typically at the level of the T2-T3 vertebrae. It is an important anatomical landmark used in medical assessments and procedures, such as central line placement. The sternal notch serves as a reference point for the location of various structures in the neck and thorax.
The dural sac end on what vertebral level?
S3
At what cervical vertebral level is the cricoid cartilage?
In the human the level of cricoid is the 6th cervical vertebra.
The union of the manubrium and the body of the sternum is an important landmark of the chest and is callled?
The manubrium is united to the body of the sternum either by an amphiarthrodial joint-a piece of fibrocartilage connecting the segments-or by a diarthrodial joint, in which the articular surface of each bone is clothed with a lamina of cartilage.
What is the vertebral level of the hyoid bone?
The hyoid bone is at the level/in line with the third cervical (C3) vertebra.
What are the events that occur at the sternal angle?
1. The bifurcation of the trachea 2. Concavity of the arch of aorta 3. Just above the bifurcation of the pulmonary trunk 4. The azygos vein enters the superior vena cava 5. The thoracic duct reaches the left side of the esophagus in its passage upwards from the abdomen 6. Ligamentum arteriosum 7. Left recurrent laryngeal nerve recurves below the ligamentum arteriosum. 8. superficial part of cardiac plexus 9. Deep part of cardiac plexus. 10. Th4-Th5 intervertebral disc. Aliu Oluwapelumi
What vertebral level does the sympathetic nerve leave the spinal cord?
Fourth thoracic
