Semispinalis Thoracis
Semispinalis thoracis bụ nke mbụ na nke kachasị elu nke òtù muscle semispinalis. Mpako, n'ọnọdụ a, na-ezo aka na ahụ ike nke ọnọdụ ya kacha nso n'elu - na-adọrọ na ndị ọzọ na ahụ ike na otu, ya bụ.
Semispinalis thoracis na-esite n'usoro a na-agagharị agagharị nke obere thoracic vertebrae. Ọ na-adakwasị usoro ntụgharị nke mkpụrụedemede 4 nke thoracic na obere akwụkwọ vertbra.

Semispinalis Cervicis
Cervicis semispinalis amalite, ma ọ bụ sitere na, usoro mbugharị nke 5 ma ọ bụ 6 thoracic vertebrae tinyere usoro ihe omume nke 4th to 7th ceteral vertebrae.

Semispinalis Capitis
Ọkpụkpụ semispinalis na-ebili, ma ọ bụ sitere, site na ntụle nke usoro ntụgharị nke mkpụrụedemede 6 ma ọ bụ 7, nakwa dịka ọhụụ (cheta na ndị a bụ usoro nke mejupụtara nkwonkwo facet) nke 4th, 5th and 6th cervical vertebrae.
