Finally, the left and right brachiocephalic veins join to form the superior vena cava, which delivers deoxygenated blood to the right atrium of the heart. [2] The jugular vein has tributaries consisting of petrosal sinus , facial , lingual , pharylingual, the thyroid , and sometimes the occipital vein .
The anterior jugular vein varies considerably in size, bearing usually an inverse proportion to the external jugular. [1] Most frequently, there are two anterior jugulars, a right and left. [1] [4] However, there is sometimes only one. [1] A duplicate anterior jugular vein may be present on one side, which may cross over the midline.
The internal jugular vein is a paired jugular vein that collects blood from the brain and the superficial parts of the face and neck.This vein runs in the carotid sheath with the common carotid artery and vagus nerve.
The anterior cardinal veins (precardinal veins) contribute to the formation of the internal jugular veins and together with the common cardinal vein form the superior vena cava. The anastomosis between the two anterior cardinal veins develops into the left brachiocephalic vein .
The inferior vena cava is the larger of the two. The inferior vena cava is retroperitoneal and runs to the right and roughly parallel to the abdominal aorta along the spine. Deep, superficial, and perforator veins. The three main compartments of the venous system are the deep veins, the superficial veins, and the perforator veins. [15]
In anatomy, the venae cavae (/ ˈ v iː n i ˈ k eɪ v i /; [1] sg.: vena cava / ˈ v iː n ə ˈ k eɪ v ə /; from Latin 'hollow veins') [2] are two large veins (great vessels) that return deoxygenated blood from the body into the heart. In humans they are the superior vena cava and the inferior vena cava, and both empty into the right atrium ...
Blood vessels are the tubular structures of a circulatory system that transport blood throughout a vertebrate's body. [1] Blood vessels transport blood cells, nutrients, and oxygen to most of the tissues of a body.
Anterior Extreme Position (AEP): the forwardmost position of the leg (i.e. usually the start of stance phase). Posterior Extreme Position (PEP): the rearmost position of the leg (i.e. usually the start of swing phase). Step duration: elapsed time between two onsets of stance.
