Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
The spines are the relatively large, radiating organs; the glochids are the fine prickles in the centres of the bunches. Glochids ( Opuntia microdasys monstrose ) Glochids or glochidia ( sg. : "glochidium") are hair-like spines or short prickles, generally barbed, found on the areoles of cacti in the sub-family Opuntioideae .

It causes inflammation of the spinal joints (vertebrae) that can lead to severe, chronic pain and discomfort. In more advanced cases this inflammation can lead to ankylosis—new bone formation in the spine causing sections of the spine to fuse in a fixed, immobile position.
However, neuropathies may be due to either inflammatory [6] or non-inflammatory causes, [7] and the term encompasses any form of damage, degeneration, or dysfunction, while neuritis refers specifically to the inflammatory process. As inflammation is a common reaction to biological insult, many conditions may present with features of neuritis.
Prickles and thorns are an evolved defense against herbivores — animals that eat plants — and can also aid in growth, plant competition and water retention, according to the study. It was ...

This joint is located where the base of the spine, known as the sacrum, and the pelvis, known as the ilium, intersect. "Itis" is a Latin term denoting inflammation.
