The basioccipital bone is a skull bone located at the base of the occipital region. The spelling of this word can be broken down using IPA phonetic transcription: /ˌbeɪsioʊˈsɪpɪtəl boʊn/. The first part "basi-" derives from the Greek word "basis" meaning base, and "-occipital" refers to the occipital bone. The correct pronunciation of this word is "bay-see-oh-sip-ital bone". This bone serves as an important attachment point for various muscles and ligaments in the head and neck region.
The basioccipital bone is a singular bone located at the base of the skull in vertebrate animals, including humans. It forms a part of the occipital region, which is situated at the posterior end of the cranium. The basioccipital bone is specifically found in the occipital bone complex and is one of several bones that contribute to the formation of the occipital region.
Anatomically, the basioccipital bone is positioned between the foramen magnum, which is the large opening in the base of the skull through which the spinal cord passes, and the sphenoid bone, which makes up part of the eye sockets. It plays a crucial role in supporting and stabilizing the skull.
The basioccipital bone can generally be described as a flat, quadrilateral-shaped bone. Its superior aspect attaches to the occipital bone, while the inferior aspect articulates with the first vertebra of the spinal column, known as the atlas. This articulation allows for movements such as nodding the head. Additionally, the basioccipital bone contains several depressions and processes that serve as attachment points for various ligaments and muscles involved in head and neck movements.
Overall, the basioccipital bone is an essential component of the skull, providing structural support, facilitating movement, and aiding in the protection of the brain and spinal cord.

The word "basioccipital bone" is derived from two terms: "basi-" and "occipital".
1. "Basi-" is a combining form, derived from the Greek word "basis", meaning "base" or "foundation". In medical terminology, it is used to refer to structures located at the base of the skull or other anatomical parts.
2. "Occipital" refers to the occipital bone, which is a bone located at the back and base of the skull in vertebrates. It forms the posterior part of the cranium and protects the brain.
Thus, combining "basi-" with "occipital" results in "basioccipital", describing the bone located at the base of the occipital region.
