Nerve point of neck
Nerve Point of Neck
The Nerve Point of Neck (pronunciation: /nɜːrv pɔɪnt ɒv nɛk/) is a significant anatomical location in the human body where several important nerves converge.
Etymology
The term "Nerve Point of Neck" is derived from the Latin words 'nervus' meaning 'nerve', 'punctum' meaning 'point', and 'collum' meaning 'neck'.
Anatomy
The Nerve Point of Neck, also known as Erb's Point, is located in the posterior triangle of the neck, about 2.5 cm above the clavicle. It is the site where the spinal accessory nerve crosses the sternocleidomastoid muscle. This point is significant as it is where the main branches of the brachial plexus and cervical plexus emerge.
