What is the plane of the sternal angle?

The thoracic plane, also known as the transthoracic plane or the plane of Ludwig is an artificial horizontal plane used to divide the mediastinum into the superior mediastinum

superior mediastinum
Superior mediastinum is an artificially divided wedge-shaped compartment of the mediastinum located between the thoracic plane inferiorly and the thoracic inlet superiorly. The inferior mediastinum, comprising of the anterior, middle and posterior parts, lies inferiorly. › articles › superior-mediastinum

Where is the sternal angle?

The sternal angle, which varies around 162 degrees in males, marks the approximate level of the 2nd pair of costal cartilages, which attach to the second ribs, and the level of the intervertebral disc between T4 and T5. In clinical applications, the sternal angle can be palpated at the T4 vertebral level.

What is the level of Carina?

The carina represents the inferior termination of the trachea into the right and left main bronchi. The carina usually sits at the level of the sternal angle and the T4/T5 vertebral level in the thoracic plane.

Why sternal angle is important?

Clinical Significance

The sternal angle is an important clinical landmark for identifying many other anatomical points: It marks the point at which the costal cartilages of the second rib articulate with the sternum. This is particularly useful when counting ribs to identify landmarks as rib one is often impalpable.

What is the Manubrium?

The manubrium is the most massive, thickest, and squarest of three main sternal elements. It is the superior-most element of the sternum and is the widest part of this bone. b. Clavicular notches occupy the superior corners of the sternum. It is here that the manubrium articulates with the right and left clavicles.

Where is the 2nd intercostal space?

From the angle of Louis, move your fingers to the right and you will feel a gap between the ribs. This gap is the 2nd Intercostal space. From this position, run your fingers downward across the next rib, and the next one.


Where is the true ribs?

True ribs: The first seven ribs attach to the sternum (the breast bone) in the front and are known as true ribs (or sternal ribs). False ribs: The lower five ribs do not directly connect to the sternum and are known as false ribs.Mar 29, 2021


Where is your second rib?

The second rib attaches to the sternum at the sternal angle. Since the first rib is hidden behind the clavicle, the second rib is the highest rib that can be identified by palpation. Thus, the sternal angle and second rib are important landmarks for the identification and counting of the lower ribs.


What is the difference between thorax and chest?

The thorax is also called the chest and contains the main organs of respiration and circulation. The heart through its main artery, the aorta, pumps oxygenated blood to all parts of the body.


What is the function thoracic cavity?

The function of the thoracic cavity is to house and protect several vital organs and structures of the body.


Where is thorax located?

In humans and other hominids, the thorax is the chest region of the body between the neck and the abdomen, along with its internal organs and other contents. It is mostly protected and supported by the rib cage, spine, and shoulder girdle.


How many cm is above the carina?

On a radiograph acquired with the neck in the neutral position, a distance of 5-7 cm above the carina is generally considered acceptable for adults.


What is secondary carina?

Anatomy: secondary carina: right side. On the right, the carina between the right middle lobe bronchus and the bronchus to the right lower lobe is named the right carina 2 or RC-2, The carina dividing the right upper lobe from the bronchus intermedius is called the right carina 1 or RC-1.


How do I identify my carina?

Traditionally, the carina has been located by the radiologist either by taking the position as the middle of the T4-T5 interspace; or by using the Dee Method, which involves identifying the aortic arch and then drawing a line inferomedially through the middle of the arch at a 45-degree angle to the midline.Nov 25, 2018


What is thoracic space?

  • Thoracic cavity, also called chest cavity, the second largest hollow space of the body. It is enclosed by the ribs, the vertebral column, and the sternum, or breastbone, and is separated from the abdominal cavity (the body’s largest hollow space) by a muscular and membranous partition, the diaphragm.


What are thoracic spine numbers?

  • The thoracic spine is an area in the upper middle of the spine that contains 12 vertebrae known as the thoracic vertebrae. These vertebrae are referred to with the initial “T” and a number reflecting their position in the spine, with T-1 being the highest thoracic vertebra and T-12 being the lowest.


What is thoracic radiology?

  • Chest (Thoracic) Radiology. Chest Radiology is an integrated service that encompasses all modes of thoracic imaging. The chest service staff are responsible for all conventional chest radiography, all thoracic CT, thoracic MRI and interventional procedures, including lung biopsies and diagnostic pleural drainages.


What is posterior thoracic?

  • Anatomical terminology. [edit on Wikidata] The posterior thoracic nucleus, (Clarke's column, column of Clarke, dorsal nucleus, nucleus dorsalis of Clarke) is a group of interneurons found in the medial part of lamina VII, also known as the intermediate zone, of the spinal cord.
