M multifidus

Dissection, digitization, and three-dimensional modeling of lumbar multifidus, lateral views. A: Dissection of superficial (red), intermediate (yellow), and deep (purple) regions. B, C, D, E, F: Segments of the superficial region attaching to L1L5 spinous processes. G: Threedimensional reconstruction of the digitized specimen shown in A. H: Segments of the intermediate region attaching to the L1L4 spinous processes. Note that there is no intermediate LMT attaching to the spinous process at L5. I: Segments of the deep region attaching to the L1L5 laminae. J: Regions of LMT attaching to the L5 spinous process. Intermediate LMT is absent at L5. LMT, lumbar multifidus; sp, spinous process; mp, mammillary process; tp, transverse process; PSIS, posterior superior iliac spine; L, lumbar

Centura pelvina

Doua oase coxale:

articulate posterior cu osul sacru (articulatia sacrailiaca) articulate anterior intre: semifiza pelviana.

Bazinul (pelvisul) incheie terminal cavitatea trunchiului. Osul coxal este format, prin sudarea la puberate a 3 oase:

ilium, ischium, pubis unite prin cartilajul in Y menajeaza gaura obturata, inchisa de membrana obturatoare Prin fata interna contribuie la constituirea foselor iliace si a stramtorii superioare a bazinului care formeaza limita intre bazinul mare si bazinul mic Pe fata lor externa si central exista o cavitate scobita prin care se face articulatia cu capul femural.
