The ansa cervicalis (or ansa hypoglossi in older literature [citation needed]) is a loop formed by muscular branches of the cervical plexus formed by branches of cervical spinal nerves C1-C3. The ansa cervicalis has two roots - a superior root (formed by branch of C1) and an inferior root (formed by union of branches of C2 and C3) - that unite ...

2023年11月3日 · The ansa cervicalis (C1-C3) is a nerve loop which stems from the cervical plexus and innervates the three out of four infrahyoid neck muscles. It is usually located on the anterolateral aspect of the carotid sheath (or inserted into it), deep to …

The ansa cervicalis, which innervates the infrahyoid muscles, is a neural complex in the neck formed by the combination of the ventral rami of the first three or four cervical spinal nerves. It is comprised of both superior and inferior roots.

2023年9月23日 · The ansa cervicalis (or ansa hypoglossi, an archaic synonym) is a component of the cervical plexus which gives muscular branches to the geniohyoid muscle of the suprahyoid group and most of the infrahyoid (strap) muscles (excluding the thyrohyoid muscle).

Ansa Cervicalis refers to a loop of nerves originating from the first three cervical nerves (C1-C3) that innervate the infrahyoid muscles, except the thyrohyoid muscle. It consists of superior and inferior roots formed by different cervical nerves and plays a …

2025年1月20日 · The ansa cervicalis is a loop of nerves found in the neck, part of the peripheral nervous system. It is a structure formed by the fusion of fibers from the cervical spinal nerves, specifically from C1 to C3.

the ansa cervicalis innervate the infrahyoid (strap) muscles of the neck. Recently, there has been an interesting debate as to which branch of the ansa cervicalis used for la- ryngeal reinnervation would result in the best vocal quality, Frazier and Mosser7 were the first to report the anastomosis of the ansa cervicalis nerve to the

The ansa cervicalis is a neural loop in the neck formed by connecting the superior root from the cervical spinal nerves (C1-2) and the inferior root descending from C2-C3. It has various anatomical variations and can be an important acknowledgment in specific operations of …

2023年9月25日 · The ansa cervicalis is a vital component of the cervical plexus, a network of nerves located in the neck region. It plays a crucial role in the innervation of various muscles in the neck and shoulders.

Abstract: The ansa cervicalis is a neural loop in the neck formed by connecting the superior root from the cervical spinal nerves (C1–2) and the inferior root descending from C2–C3.
