How Do You Spell SPINA FRONTALIS?

1. Spina frontalis, also known as the frontal crest, is a anatomical term used in medical and anatomical contexts to describe a specific structure located in the frontal bone of the skull. The spina frontalis is a bony ridge that projects from the midline of the frontal bone, running vertically along its superior aspect. It is a prominent feature of the frontal bone and can vary in size and shape among individuals.

   The spina frontalis serves as an attachment point for various structures, including muscle fibers and ligaments. It provides support and anchorage for the muscles responsible for facial expressions, particularly those involved in raising and furrowing the eyebrows. These muscles, such as the frontalis and corrugator supercilii muscles, attach to the spina frontalis and allow for movements such as frowning, raising the eyebrows in surprise, or wrinkling the forehead.

   The presence and prominence of the spina frontalis can vary among individuals due to factors such as genetics and age. It can be observed and felt by palpation along the midline of the forehead in some individuals, forming a noticeable ridge. However, in others, it may be less pronounced or even absent.

   Overall, the spina frontalis is a bony prominence found on the frontal bone, serving as an attachment point for facial muscles and contributing to various facial expressions and movements associated with the eyebrows and forehead.

2. Forntal spine, nasal spine of the frontal bone; a projection from the center of the nasal part of the frontal bone, which lies between and articulates with the nasal bones and the perpendicular plate of the ethmoid.
