different between kyphosis vs kyphosid

English

Alternative forms

• cyphosis (dated)

Etymology

From Ancient Greek ????? (kuphós, “humpback, bent”) +? -osis

Noun

kyphosis (countable and uncountable, plural kyphoses)

1. (anatomy) The normal convex curvature of the spine in the thoracic and sacral regions.
2. (pathology) An abnormal convex curvature of the spine in the cervical or lumbar regions of the spine.

   Synonyms: roundback, Kelso's hunchback

Usage notes

Some degree of kyphosis is normal and non-pathological in the thoracic and sacral regions, so an excessive curvature in either of those regions would be described as hyperkyphosis. However, the cervical and lumbar regions normally exhibit lordosis, or concave curvature, and any kyphosis in those regions would be considered pathological.

Noun

kyphosid (plural kyphosids)

1. (ichthyology) Any of the perciform fish of the family Kyphosidae (the sea chubs).
   • 1967, Bulletin of the Museum of Comparative Zoology, Volume 135, page 50,

     The kyphosids are today one of the most primitive percosid families.

     A few apogonids are similarly shaped and pigmented, but none are as robust as kyphosids, and all have a prominent gas bladder and a divided dorsal fin with fewer elements. Heavily pigmented perciform larvae such as Iatids and toxotids have different skin meristics and smaller head spines than kyphosids.

   • 2009, Alison L. Green, David R. Bellwood, Monitoring Functional Groups of Herbivorous Reef Fishes as Indicators of Coral Reef Resilience, page 21,

     Siganids and kyphosids are less speciose than scarines and acanthurids, and are more conservative in their feeding habitats (Choat 1991, Choat et al 2002).
