Pronunciation: [sɪnsˈe͡ɪkɹəm] (IPA) 
The word "synsacrum" is spelled with eleven letters and is pronounced /sɪnˈsækrəm/. The 's' and 'y' make the /sɪ/ sound, followed by the 'n' sound. The 'a' makes the /æ/ sound, then the 'c' makes the /k/ sound. The 'r' makes the /r/ sound, followed by the 'u' which makes the /ʌ/ sound. Finally, the 'm' makes the /m/ sound. This word refers to the fused vertebrae of the pelvic region in some birds and reptiles.
A synsacrum is a term used in the field of ornithology to refer to a fused structure formed by the fusion of multiple vertebrae and the pelvic girdle of a bird. The word "synsacrum" is derived from the Greek words "syn," which means together, and "sacrum," which refers to the triangular bone at the base of the spine.
The synsacrum is a vital component of a bird's skeletal system, serving as a strong and rigid connection between the spinal column and the pelvic region. This fusion of bones provides structural support and stability, enabling birds to withstand the demands of flight and other physical activities. Additionally, the synsacrum plays a crucial role in the distribution of forces during locomotion, by absorbing and transferring the impact of wing beats and landing.
The complexity and fusion of the synsacrum vary among different bird species, depending on their size, flight capabilities, and ecological niche. In general, larger birds have a more elaborate and fused synsacrum, providing increased stability and strength. The synsacrum also facilitates reproductive processes in female birds by supporting the weight and motion of their internal reproductive organs.
Overall, the synsacrum represents an adaptation of the avian skeleton, allowing birds to exhibit their unique and diverse range of flying abilities, while providing the necessary support and structural integrity for their vital functions.
The word "synsacrum" is formed by combining two words: "syn-" and "sacrum".
The word "syn-" is a prefix derived from the Greek word "syn" meaning "with" or "together". It is commonly used to indicate association, combination, or union.
The word "sacrum" comes from Latin and is derived from the Latin word "sacer" meaning "sacred". In anatomy, the sacrum refers to the triangular bone at the base of the spine, situated between the two hip bones.
Therefore, "synsacrum" is formed by combining the prefix "syn-" meaning "together" and "sacrum" referring to the bone at the base of the spine. It is used to describe a fused or united sacrum, typically found in certain groups of birds and reptiles.
