interspine

English

Etymology

inter- +‎ spine

Adjective

interspine (not comparable)

1. Between spines.
   • 1980, Developments in Theoretical and Applied Mechanics, page 82:

     The devices limit the range of motion of the spine that are trapped within it so that there is a reduction in the amount of interspine bending and interspine torsion for the regions in which the garments are applied.

   • 2004, Gordon M. Shepherd, The Synaptic Organization of the Brain, page 547:

     For example, inhibitory synapses on the trunk dendrite would reduce interspine communication and could control saltatory conduction between spines (Shepherd and Brayton, 1987).

   • 2004, Chris I. De Zeeuw, Federico Cicirata, Creating Coordination in the Cerebellum, page 54:

     This effect is aimed at inducing large interspine intervals to accommodate a high number of voltage dependent Ca²⁺ channels.

   • 2010, Rafael Yuste, Dendritic Spines, page 38:

     Finally, based on the link between spine head diameter and interspine distance, one could also expect corresponding increases in interspine distances in distal dendrites.

Noun

interspine (plural interspines)

1. A spine of connective tissue that connects the rays of a fish's fin.
   • 1864, Geological Survey of Great Britain, Figures and Descriptions Illustrative of British Organic Remains:

     It consists of 10 short rays, articulating with 10 long and slender interspines, the anterior one of the series being 1 8/10 inch in length.

   • 1922, Journal of the Marine Biological Association of the United Kingdom, volume 12, page 201:

     The first interspine is roughly parallel to the outline of the brain and to it is attached the succeeding ray.

   • 2012, J.H.S. Blaxter, The Early Life History of Fish, page 680:

     Interspines begin to differentiate, but hypurals and epurals do not.

2. The area between spines on a sunspot.
   • 2013, Issues in Astronomy and Astrophysics, page 924:

     This convective signature is the same in spines and interspines.

   • 2015, Sanjiv K. Tiwari, Ronald L. Moore, Amy R. Winebarger, Shane E. Alpert, “Transition-Region/Coronal Signatures and Magnetic Setting of Sunspot Penumbral Jets: Hinode (SOT/FG), Hi-C and SDO/AIA Observations”, in arXiv‎^[1], →DOI:

     It was proposed that the PJs form as a result of reconnection between two magnetic components of penumbra (spines and interspines), and that they could contribute to the transition region (TR) and coronal heating above sunspot penumbrae.

3. The interior of the spinal cord.
   • 2016, Michael P Steinmetz, Edward C. Benzel, Benzel's Spine Surgery:

     Avoid unnecessary dissection, especially of the interspine and ligaments.
