Where is rib number 9 located?
In the anterior thorax, the first 7 pairs of ribs are attached to the sternum or breastbone by cartilage. The lower 5 ribs do not attach to the sternum. The 8th, 9th, and 10th ribs are attached to each other by costal cartilage.
Where is the Midsternal line?
anterior thorax
The Midsternal line is used to describe a part of the surface anatomy of the anterior thorax. The midsternal line runs vertical down the middle of the sternum.
Where is the 9th and 10th rib located?
The ninth rib has a frontal part at the same level as the first lumbar vertebra. This level is called the transpyloric plane, since the pylorus is also at this level. The tenth rib attaches directly to the body of vertebra T10 instead of between vertebrae like the second through ninth ribs.
Why is the needle inserted in the eighth interspace?
Why is the needle inserted in the eighth interspace? The needle needs to be inserted below the level of the lungs, in the costodiaphragmatic recess, which would be the eighth or lower interspace.
Where is the angle of Louis?
The sternal angle (also known as the angle of Louis, angle of Ludovic or manubriosternal junction) is the synarthrotic joint formed by the articulation of the manubrium and the body of the sternum. Anterior surface of sternum and costal cartilages. (Sternal angle not labeled, but visible at second costal cartilage.)
How do you calculate intercostal space?
Counting the rest.
- The first palpable rib is the second rib.
- Intercostal spaces are numbered respectively to the superior rib, i.e. second intercostal space is below the second rib.
- Lower ribs articulate with the sternum indirectly. It is hard to palpate lower ribs and intercostal spaces close to the sternum.
Where is Midaxillary line?
axilla
The midaxillary line originates in the axilla, or armpit, and passes vertically downwards. It is situated in between the anterior axillary line and posterior axillary line.
What’s the Midclavicular line?
Medical Definition of midclavicular line : an imaginary line parallel to the long axis of the body and passing through the midpoint of the clavicle on the ventral surface of the body.
Where is the 8th 9th and 10th rib?
The 8th, 9th, and 10th rib pairs don’t connect directly to your sternum, but they are connected to each other by cartilage that attaches to the costal cartilage of the 7th rib pair. These ribs also attach to your spine in the back. The 11th and 12th rib pairs are the lowest in the rib cage.
Where is the midaxillary line?
Where is the midaxillary line located? The midaxillary line originates in the axilla, or armpit, and passes vertically downwards. It is situated in between the anterior axillary line and posterior axillary line.
Which intercostal space is used for thoracentesis?
Needle thoracocentesis is a life saving procedure, which involves placing a wide-bore cannula into the second intercostal space midclavicular line (2ICS MCL), just above the third rib, in order to decompress a tension pneumothorax, as per Advanced Trauma Life Support (ATLS) guidelines.
Why is it called angle of Louis?
1 This anatomic landmark is named after the French surgeon Antoine Louis (1723–1792). Since then, the medical literature has variously described this landmark as the Angle of Louis, Lewis, and Ludwig.
Where is the 5th intercostal space Midclavicular line?
apex
The apex (the most inferior, anterior, and lateral part as the heart lies in situ) is located on the midclavicular line, in the fifth intercostal space. It is formed by the left ventricle. The base of the heart, the posterior part, is formed by both atria, but mainly the left.
Where is the 11th intercostal space?
The intercostal space (ICS) is the anatomic space between two ribs (Lat. costa). Since there are 12 ribs on each side, there are 11 intercostal spaces, each numbered for the rib superior to it….
| Intercostal space | |
|---|---|
| TA2 | 1102 |
| FMA | 12243 |

What does Midaxillary line mean in anatomy?
Medical Definition of midaxillary line : an imaginary line through the axilla parallel to the long axis of the body and midway between its ventral and dorsal surfaces.
What does Midaxillary mean?
mid·ax·il·lar·y line (mid-ak’si-lar-ē līn) [TA] An imaginary division halfway between the anterior axillary line and the posterior axillary line, passing through the apex of the axilla. Synonym(s): median axillary line [TA] .
What is the importance of Midclavicular line?
Clinical significance It is useful for evaluating hepatomegaly and identifying heart sounds, as well as finding the gallbladder. (The gallbladder is at the intersection of the midclavicular line and the transpyloric plane.)
Why is ribs 8 9 10 are called false ribs?
The first seven pairs of ribs are attached directly to the sternum by costal cartilages and are called true ribs. However, 8th, 9th and 10th ribs are known as false ribs because they do not join sternum directly and they are attached to the coastal cartilage of the 7th rib.
Why is it called false ribs?
The upper seven pairs of ribs are known as true ribs because their costal cartilages articulate anteriorly directly with the sternum. The lower five pairs of ribs (ribs eight to twelve) are known as false ribs because their costal cartilages do not articulate directly with the sternum.
