Origin: A borrowing from Latin, combined with an English element; perhaps modelled on a Latin lexical item. Etymons: Latin pīnus , -iform comb. form.

Etymology: < classical Latin pīnus pine n.² + -iform comb. form, perhaps after scientific Latin piniformis (1845 or earlier as a specific name).The English word is apparently found earlier in a German context in the following: 1888 H. Obersteiner Anleitung beim Studium des Baues der nervösen Centralorgane 213 ..die Schleifenkreuzung (Decussatio Lemnisii, piniform decussation).

Anatomy. rare.

Having the shape of a pine cone; esp. in piniform decussation n. the superior pyramidal decussation, a roughly conical area of the anterior medulla oblongata between the olivary nuclei.
