The suprasternal notch is a visible dip in between the neck, between the clavicles, and above the manubrium of the sternum. It is at the level of the T2 and T3 vertebrae. [2] The trachea lies just behind it, rising about 5 cm above it in adults. [3]
Extending lateralward from the posterior half of the condyle is a quadrilateral plate of bone, the jugular process, excavated in front by the jugular notch, which, in the articulated skull, forms the posterior part of the jugular foramen. The jugular notch may be divided into two by a bony spicule, the intrajugular process, which projects ...
The suprasternal notch (jugular notch) is located in the middle at the upper broadest part of the manubrium. This notch can be felt between the two clavicles. On either side of this notch are the right and left clavicular notches. [1] The manubrium joins with the body of the sternum, the clavicles and the cartilages of the first 1.5 pairs of ...
The jugular process is a quadrilateral or triangular bony plate projecting lateralward from the posterior half of the occipital condyle; it is a part of the lateral part of the occipital bone. [ 1 ] The jugular process is excavated in front by the jugular notch of occipital bone (which forms the posterior part of the jugular foramen ).
This separates the carotid artery from the vertebral artery and the carotid artery can be massaged against this tubercle to relieve the symptoms of supraventricular tachycardia. The carotid tubercle is also used as a landmark for anaesthesia of the brachial plexus and cervical plexus. The cervical spinal nerves emerge from above the cervical ...
The angle also marks the level of a number of features: Boundary between the superior and inferior portion of the mediastinum [citation needed] Passage of the thoracic duct from right to left behind esophagus [citation needed] Tracheal bifurcation. [2]: 387, 1039, 1060 The carina of the trachea is thus, present here. It is deep to the sternal ...
Plane located halfway between the jugular notch and the upper border of the symphysis pubis; Typically located at the lower border of L1; Cuts through the pylorus and the tips of the ninth costal cartilages; The subcostal plane. Transverse plane through the inferior border of costal margin; Typically located at the superior border of L3, or ...
Jugular notch in the manubrium of the sternum: Anterior boundary: Midline of the neck from chin to the jugular notch Posterior boundary: The anterior margin of sternocleidomastoid: Superior boundary (base) The lower border of the body of the mandible, and a line extending from the angle of the mandible to the mastoid process
