The hip bones in snakes (and in humans) are called the pelvis.
Anatomical directional terms and bodyplanes describe the locations of structures in relation to other structures or locations in the body.
The skleletal system
Homologous structures.
The term you're looking for is "vestigial." In evolutionary biology, vestigial structures are remnants of organs or body parts that had a function in ancestral species but have lost their original purpose in the current organism. Examples include the human appendix or the hind limb bones in some snakes.
Corpus bones are usually referencing the bony structures that make up the skeletal system. These bones develop from mesoderm tissue during embryonic development. The term "corpus" itself comes from Latin, meaning body or structure.
Phalanges is the overall term for the structures (i.e the fingers) and these are composed of phalanx's (distal, proximal, and middle).
Botanical snakes is not a scientifically recognized term. It might refer to plants that have snake-like characteristics in their appearance, such as twisted or winding stems or leaves.
There is no special medical term meaning obscured by overlying osseous structures. The phrase means that something can't be seen well because of the bones between the structure of interest and the viewer.
Anatomical structures refer to the parts and components that make up an organism's body, such as organs, tissues, and bones. Understanding these structures helps researchers study the function and organization of living organisms.
In the context of snakes, the term "morph" refers to a specific color or pattern variation within a species.
The term "osseous structures unremarkable" typically means that the bones and related structures appear normal and show no signs of abnormalities or significant findings in medical imaging, such as X-rays or CT scans. Essentially, it indicates that there are no visible fractures, lesions, or other issues present in the bone tissue. This phrase is often used in radiology reports to convey that the examined bones are healthy and intact.
