In adults, the internal thoracic artery lies closest to the sternum at the first intercostal space. The gap between the artery and lateral border of the sternum increases when going downwards, up to 1.1 cm to 1.3 cm at the sixth intercostal space. In children, the gap ranges from 0.5 cm to 1.0 cm.

For example, the reciprocal centimetre, cm −1, is an energy unit equal to the energy of a photon with a wavelength of 1 cm. That energy amounts to approximately 1.24 × 10 −4 eV or 1.986 × 10 −23 J. The energy is inversely proportional to the size of the unit of which the reciprocal is used, and is proportional to the number of ...
Level 1 players would assume that everyone else was playing at level 0, responding to an assumed average of 50 in relation to naive play, and thus their guess would be 33 (2/3 of 50). At k-level 2, a player would play more sophisticatedly and assume that all other players are playing at k-level 1, so they would choose 22 (2/3 of 33). [9]
In two-thirds of a large number of cases, the length of the internal iliac varied between 2.25 and 3.4 cm.; in the remaining third it was more frequently longer than shorter, the maximum length being about 7 cm. the minimum about 1 cm. [citation needed]
The renal arteries normally arise at a 90° angle off of the left interior side of the abdominal aorta, immediately below the superior mesenteric artery. [1] They have a radius of approximately 0.25 cm, [2] 0.26 cm at the root. [3] The measured mean diameter can differ depending on the imaging method used.
Normally, vertebral artery blood flow velocity can be 63.6 ± 17.5 cm/s during PSV and 16.1 ± 5.1 cm/s during EDV according to a study done by Kuhl et al. [16] Due to vertebral artery dominance, measurements can vary on both sides, for example, another study by Seidel et al. found that the right side had an average of 45.9 cm/s and the left ...
The external carotid artery arises from the common carotid artery just inferior to the upper border of the thyroid cartilage. [1]At its origin, this artery is closer to the skin and more medial than the internal carotid, and is situated within the carotid triangle.
The femoral artery represents the continuation of the external iliac artery beyond the inguinal ligament underneath which the vessel passes [2] to enter the thigh. [3] The vessel passes under the inguinal ligament just medial of the midpoint of this ligament, [2] midway between the anterior superior iliac spine and the symphysis pubis (mid ...
