LONGISSIMUS Meaning and
Definition
-
Longissimus is a Latin term used in anatomy to refer to a specific muscle found in the human body, known as the longissimus muscle. The word "longissimus" itself translates to "longest" in English, indicating its elongated shape. This muscle is a part of the erector spinae muscle group, which runs along the back and helps to support and extend the vertebral column.
The longissimus muscle is divided into three parts: the longissimus thoracis, longissimus cervicis, and longissimus capitis, each responsible for different movements. The longissimus thoracis is the largest division and is located in the thoracic region of the spine, extending from the pelvis up to the head. It assists in extending the spine and also helps to laterally flex and rotate the spine. The longissimus cervicis is situated in the cervical region and aids in neck extension. Finally, the longissimus capitis is located in the posterior region of the head and helps with extending and rotating the head.
Overall, the longissimus plays a crucial role in maintaining posture, supporting the spine, and facilitating movements of the neck, head, and back. Its length, hence the name "longissimus," allows for a wide range of motions and contributes to the overall stability of the vertebral column.
