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.

Arch of aorta ends
Descending aorta begins
The body of the vertebrae
Arch of aorta begins
The Burification of the pulmonary track
The level of rib where it attached to the sternum through Costal cartilage.
The Burification of the trachea
Superior and inferior mediastinum are demarcated
They occurred then.
At most one of the events can occur.
Equally likely events.
Yes, they are. Mutually exclusive events cannot occur together. Complementary events cannot occur together either because an event and its complement are the negative of each other.
We would need to know which events you're referring to to respond to this question.
90o
it marks the position of the second rib
The second pair of ribs or the True ribs
at the level of the inter-vertebral disc between T4 and T5.
Sternal refers to the sternum, which is the breast bone.
The sternal area is around the sternum (breastbone) in the center of the chest.
8 are sternal & 10 are asternal.
The xyphoid process is the inferior sternal bony landmark.
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
This results in intercostal and sternal recession in small children with airway obstruction.
Parallel events are similar events. Simultaneous events are events that occur at the same time. Both simultaneous and parallel events occur at different places.
The definition of critical angle is the angle of incidence that refraction can still occur.
