Splenius (/'spliniəs/) is a medical term used to describe a group of muscles located at the back of the neck. The word comes from the Latin term "splenius," which means "bandage." The IPA phonetic transcription helps to explain the pronunciation of the word, with the apostrophe representing a primary stress placed on the first syllable. The letters "s-p-l" are pronounced as a consonant cluster, while the vowel sounds in the second syllable, "i" and "ə," represent a short "i" followed by a neutral vowel.
The term "Splenius" refers to a group of muscles found in the human body. Specifically, the word is commonly used in anatomy to describe two separate muscles: the splenius capitis and the splenius cervicis. Both muscles are located in the back of the neck and upper back region.
The splenius capitis, also known as the "muscle of the head," originates in the nuchal ligament and inserts into the mastoid process, a bony protuberance behind the ear. This muscle plays a crucial role in the movement and stabilization of the head and neck. It participates in the extension, lateral flexion, and rotation of the cervical spine.
On the other hand, the splenius cervicis, or "muscle of the neck," is located just below the splenius capitis. It arises from the spinous processes of the upper thoracic and lower cervical vertebrae and inserts into the transverse processes of the upper cervical vertebrae. This muscle is responsible for various movements of the cervical spine, including rotation, lateral flexion, and extension.
Overall, the splenius muscles contribute to the overall flexibility, stability, and functionality of the neck and upper back region. They are vital in maintaining proper posture and enabling movements of the head and neck in everyday activities and athletic pursuits.

The word "Splenius" has its etymology derived from the Greek word "splēnion", which means "bandage" or "sling". In anatomy, the term "splenius" refers to a pair of muscles: the splenius capitis and splenius cervicis, which are long muscles located in the back of the neck and upper back. These muscles have a band-like appearance, resembling a "sling", which is believed to be the reason for the name "Splenius".
