Hauv neeg laus , tsuas yog metaphysis thiab diaphysis yog tam sim no (Daim duab 1).
Ib yam li ntawd, metaphysis muaj li cas?
Hauv cov neeg laus cov metaphysis yog tsim feem ntau ntawm cov pob txha tshem tawm (trabecular) uas muaj ntawm osseous daim hlau thiab rods uas hla ib leeg ntawm ntau los yog tsawg txoj cai ces kaum ntawm lub intertrabecular marrow qhov chaw.

Lub phaj tsuas pom muaj nyob rau hauv cov menyuam yaus thiab cov tub ntxhais hluas; nyob rau hauv cov laus , who muaj nres loj hlob, lub phaj yog hloov los ntawm ib tug mob epiphyseal kab.
