• A. A- Dorsal septum, B- Dorsal horn, C- Grey matter, D- Central cavity, E- White mater, F- Ventral horn, G- Ventral root, H- Dorsal root and ganglion
• B. A- Dorsal septum, B- Dorsal horn, C- Central cavity, D- Grey matter, E- Ventral horn, F- White matter, G- Dorsal root and ganglion, H- Ventral root
• C. A- Dorsal septum, B- Dorsal horn, C- Grey matter, D- White matter, E- Central cavity, F- Ventral root, G- Dorsal root and ganglion
• D. A- Dorsal septum, B- Dorsal horn, C- Central cavity, D- Grey matter, E- Ventral horn, F- Ventral root, G- Dorsal root and ganglion, H- White matter

Answer 1

The correct option is A A- Dorsal septum, B- Dorsal horn, C- Grey matter, D- Central cavity, E- White mater, F- Ventral horn, G- Ventral root, H- Dorsal root and ganglion

The central cavity (D) of spinal cord has cerebrospinal fluid. The H shaped gray matter (C) is centrally located and is surrounded by white matter (E). The posterior end of H shaped gray matter makes the dorsal horn (B) while its anterior end is called as ventral horn (F). Dorsal septum (A) is present in the dorsal surface of spinal cord separating the posterior funiculus. The sensory fibres and ganglion of dorsal root (H) of spinal nerve enter the gray matter while the motor fibres of ventral root (G) of spinal nerves exit the gray matter. Correct answer is A.
