- Immovably articulated, as two bones; immovable, or permitting no motion, as an articulation; pertaining to synarthrosis, or having its character.
Sorry, no etymologies found.
The articulations of the cartilages of the true ribs with the sternum are arthrodial joints, with the exception of the first, in which the cartilage is directly united with the sternum, and which is, therefore, a synarthrodial articulation.
It may be converted into fibrous tissue as in the case of the skull bones, a synarthrodial joint being the result, or it may become partly cartilaginous, in which case an amphiarthrodial joint is formed.
