	==Additional ~~images~~==		At the level of the [[cubital fossa]], the cephalic vein communicates with the [[basilic vein]] via the prominent [[median cubital vein]], which is a common site for venipuncture.

			It then continues superiorly through the '''[[deltopectoral groove]]''', the interval between the [[deltoid muscle]] and [[pectoralis major]], and pierces the '''[[clavipectoral fascia]]''' within the [[deltopectoral triangle]]. From there, it empties into the deep venous system via the [[axillary vein]].

			== '''Anatomical Relations and Variations''' ==

			* The cephalic vein lies in close proximity to the '''[[cephalic artery]] (when present)''' and the '''[[lateral cutaneous nerve of the forearm]]'''
			* Its location is '''superficial and consistent''', making it ideal for cannulation
			* The diameter, course, and communications of the vein may vary among individuals

			== '''Clinical Significance''' ==

			The cephalic vein is frequently used in:
			* '''[[Intravenous access]]''', especially when veins in the [[antecubital fossa]] are not usable
			* '''Placement of large-bore [[cannulae]]''' or [[peripherally inserted central catheters]] (PICC lines)
			* '''Insertion of [[permanent pacemaker]] leads''' through the deltopectoral groove

			Due to its accessibility and visibility, the cephalic vein is nicknamed the '''"Houseman's Friend"'''—a reference to its use by medical trainees for venous cannulation.

			== '''Etymology''' ==
			The term "cephalic" typically pertains to the [[head]]. However, in this context, the usage is a result of a '''translation error'''. When the Arabic term ''al-kífal'' (meaning "outer") from [[Avicenna]]’s ''[[Canon of Medicine]]'' was translated into [[medieval Latin]], it was mistakenly rendered as ''cephalicus'', implying an incorrect association with the head.

In [[human anatomy]], the '''cephalic vein''' (or '''antecubital vein''') is a [[superficial vein]] of the [[upper limb]].

It communicates with the [[basilic vein]] via the [[median cubital vein]] at the [[Elbow-joint|elbow]] and is located in the superficial [[fascia]] along the anterolateral surface of the [[biceps brachii muscle]].

Superiorly the cephalic vein passes between the [[deltoid muscle|deltoid]] and [[pectoralis major muscle|pectoralis major]] [[muscle]]s ([[deltopectoral groove]]) and through the [[deltopectoral triangle]], where it empties into the [[axillary vein]].

The cephalic vein is often visible through the [[skin]], and its location in the deltopectoral groove is fairly consistent, making this site a good candidate for venous access. [[Artificial cardiac pacemaker|Permanent pacemaker]] leads are often placed in the cephalic vein in the deltopectoral groove. The vein may be used for [[intravenous therapy|intravenous access]], and is sometimes referred to as the 'House-man's Friend' because a large bore [[cannula]] may be easily placed.

==Etymology==
Ordinarily the term ''[[cephalic]]'' refers to anatomy of the head. When Persian physician [[Ibn Sīnā]]'s [[The Canon of Medicine|Canon]] was translated into [[medieval Latin]], ''cephalic'' was mistakenly chosen to render the [[Arabic]] term ''al-kífal'', meaning "outer".<ref>{{cite book|last=Diab|first=Mohammad|title=Lexicon of orthopaedic etymology|year=1999|publisher=Taylor & Francis|isbn=978-90-5702-597-6|pages=54}}</ref><ref>{{cite web|last=Swenson|first=Rand|title=Etymology of shoulder and arm terms|url=http://www.dartmouth.edu/~humananatomy/resources/etymology/Shoulder_arm.htm|publisher=© O'Rahilly 2008|location=Dartmouth Medical School|accessdate=20 April 2011}}</ref>
