Squama occipitalis is a term used to describe the occipital bone of the skull. The spelling of this word can be a bit tricky, but it can be broken down using the International Phonetic Alphabet (IPA) to aid in pronunciation. The first syllable "squa" is pronounced with a /skw/ sound, while the second syllable "ma" is pronounced with a short /æ/ sound.

The term "squama occipitalis" is an anatomical term used in reference to the flat, scale-like bone located in the occipital region of the skull. It is often referred to as the occipital squama or occipital bone.
The squama occipitalis forms the posterior or back portion of the cranium, protecting the brain and supporting various structures in the head and neck. It is situated at the lower part of the back of the skull, between the parietal bones and the foramen magnum, which is the large opening that allows the spinal cord to connect with the brain.
This flat bone is roughly triangular in shape and exhibits distinct features. It typically presents a prominent external occipital protuberance, also known as the external occipital protuberance or inion, which serves as an attachment point for ligaments and muscles involved in neck and head movement. Additionally, the squama occipitalis displays the superior and inferior nuchal lines, which also provide attachment sites for muscles and connective tissues.
Overall, the squama occipitalis contributes to the structural integrity of the skull and aids in protecting the vital organs of the brain and spinal cord. Its various anatomical features enable the attachment and coordination of muscles and ligaments involved in the movement of the head and neck.
