Synonym: superficial cervical nerve loop
English:
Definition[Bearbeiten]
The superficial cervical nerve loop is a nerve loop formed by the ramus colli of the facial nerve and the ascending branches of the transversus colli nerve.
Nomenclature[Bearbeiten]
The term Ansa cervicalis superficialis is no longer used according to the latest anatomical nomenclature (as of 2016). It is now only referred to as the cervical anus and refers to the profunda cervical anus.
Topography[Bearbeiten]
The superficial cervical nerve lies between the sternocleidomastoid muscle and the platysma in the upper anterolateral half of the neck. Its connecting branch (ramus communicans) runs almost parallel to the external jugular vein and crosses the anterior jugular vein.
The lower cervical profunda lies below the sternocleidomastoid muscle.
Supply area[Bearbeiten]
The fibres of the superficial cervical sinus supply the platysma and the overlying skin.
