Question

Human vertebral formula is

• A. $C_4{T}_8{L}_4{S}_{8}C{o}_8$
• B. $C_7{T}_8{L}_5{S}_{6}C{o}_7$
• C. $C_7{T}_{12}{L}_5{S}_{4}C{o}_5$
• D. $C_7{T}_{12}{L}_5{S}_{5}C{o}_4$

Answer 1

The correct option is D $C_7{T}_{12}{L}_5{S}_{5}C{o}_4$

Vertebral formula is a formula indicating the number of vertebrae in each segment of the spinal column. For humans it is C${}_7$, T${}_{12}$, L${}_5$, S${}_7$, Co${}_4$ which is equal to 33. The letters denoting cervical, thoracic, lumbar, sacral and coccygeal.

So, the correct answer is 'C${}_7$, T${}_{12}$, L${}_5$, S${}_7$, Co${}_4$'.
