A variant case of ansa cervicalis
Ansa cervicalis (ansa cervicalis profunda, ansa nervi hypoglossi) is one of the nerve connections in the human body. Two roots make up the ansa cervicalis –radix superior and radix inferior. Its sources include the ventral rami of the cervical spinal nerves; ansa innervates all infrahyoid muscles except for the thyrohyoid muscle [1,2]. In the past few years, there has been a development in the ...
متن کاملThe Case Report: a Rare Anatomical Variant of Ansa Cervicalis
A rare variant of ansa cervicalis was discovered during routine dissection of the neck in a male cadaver. The superior root of the Ansa cervicalis was formed by the C1 ventral ramus. It fused with the vagus nerve in place of the hypoglossal nerve without any connection and descended into the carotid sheath with it. Then, C1 ventral ramus formed from the sheath and joined the inferior root from ...

AbsractA rare variant of ansa cervicalis was discovered during dissection of the neck in amale cadaver. The superior root of the Ansa cervicalis was formed by the C1 ventralramus. It accompanied with the vagus nerve in place of the hypoglossal nerve and descendedinto the carotid sheath with it. Moreover the C1 ventral ramus formed fromthe sheath and joined the inferior root from C2 and C3 ventr...
متن کاملSchwannoma of the ansa cervicalis
Schwannomas are rare neoplasms that originate from Schwann cells. We present a case report of schwannoma of the ansa cervicalis in a patient where preoperative imaging suggested thyroid pathology. A 25-year-old man presented to the otolaryngology department with a one-year history of an asymptomatic, anterior triangle neck swelling. Imaging and FNA suggested a cystic lesion of the thyroid. Howe...
متن کاملVariations in the anatomy of ansa cervicalis.
With the emerging utilisation of ansa cervicalis in nerve reconstructive surgery, it is important for surgeons to be conversant with the anatomy of these nerves. This descriptive cross sectional study aimed at describing the morphology and topographic anatomy of ansa cervicalis. We examined 38 adult human formalin-fixed cadavers. The superior root was present in 38 (100%) cases and 37 (97%) cas...
