Have a care also for the soft bones of the coccyx, and the uncinate process which projects backward from the posterior edge of each rib.
Look out for those delicate little points on the neck vertebrae, and also be very careful not to cut off those curious little appendages (called uncinate processes) that project backward from the middle of each rib.
They are serially homologous with, for example, the uncinate processes of the ribs in birds (see Figs.
Body globular in form, mantle having a pedal slit on the abdominal side; two respiratory apertures without retractor muscles; foot mostly uncinate or strap-shaped.
I have shown, that they are already to be recognized by the uncinateor hook-shaped groove for the mantle in the shell, and which proceeds from the insertion of the retractor muscles.
The thoracic ribs in almost all birds have large uncinate processes.
The sacral ribs connecting the vertebral column with the ilia are very distinct in Crocodiles; in these animals and Sphenodon the vertebral ribs have backwardly projecting uncinate processes as in birds.
The ribs do not show uncinate processes, and articulate with the vertebrae by single heads not divided into capitula and tubercula.
The ribs generally have uncinate processes and separate capitula and tubercula, but uncinate processes are absent in Chauna Palamedea and apparently in Archaeopteryx.
Projecting backwards from each is a large hooked =uncinate process.
There are generally thirteen pairs of ribs, and in no case do they have uncinate processes.
The thoracic ribs each have a single head which articulates with the centrum of the vertebra; while uncinate processes and abdominal ribs never occur.

From near the distal end an imperfectly ossified uncinate =process= (see p.
The ribs have capitula and tubercula, and often uncinate processes (see p.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "uncinate" in a variety of sentences. We hope that you will now be able to make sentences using this word.
