lesser occipital nerve

(redirected from Lesser occipital)

less·er oc·cip·i·tal nerve

[TA]
arises from cervical plexus, conveying fibers from the ventral primary rami of the second and third cervical nerves; supplies the skin of the posterior surface of the auricle and the adjacent portion of the scalp posterior to the auricle.
Synonym(s): nervus occipitalis minor [TA]

lesser occipital nerve

Etymology: AS, losian, to lose; L, occiput, back of the head, nervus, nerve
one of a pair of cutaneous branches of the cervical plexus, arising from the second cervical nerve and ascending along the side of the head behind the ear to supply the skin. It communicates with the posterior auricular branch of the facial nerve.

The cervical plexus consists of the ventral primary divisions of the first four cervical spinal nerves and gives rise to (1) the muscular branches, including the phrenic nerve and nervus descendens cervicalis, as well as (2) the sensory branches, including the lesser occipital, transverse cutaneous, supraclavicular, and great auricular nerves.
Often though, we see it manifested after physical insult to the greater or lesser occipital nerve pathways i.
The dorsal rami of C2 gives rise to the greater occipital nerve, while the lesser occipital nerve is a combination of both the C2 and C3 ventral rami.
the lesser occipital (anterior ramus of C2) supplies the skin behind the ear.
The patient elected to try cryo-analgesia of the bilateral greater and lesser occipital nerves, unfortunately without significant benefit.
It has been proposed that the clinical benefit for temporal placement may be based on coverage of the terminal branches of the trigeminal nerves, along with the communicating branches between the auriculotemporal nerve and the lesser occipital nerve.
the posterior auricular branch--which innervates the auricularis posterior, the cranially oriented muscles of the auricle, and the occipital muscles--communicates with the greater auricular nerve, the auricular branch of the vagus nerve, and the lesser occipital nerve (3)
Previous communications with branches of cervical nerves have now become communications with the lesser occipital and transverse cervical nerves.
