Qur'anic verses - Biological creation of Man (III):

A man's seed is the quintessence of his body. It is therefore said metaphorically to proceed from his loins, i.e., from his back between the hipbones and his ribs. His backbone is the source and symbol of his strength and personality. In the spinal cord and in the brain is the directive energy of the central nervous system, and this directs all action, organic and psychic. The spinal cord is continuous with the Medulla Oblongata in the brain.

The creator who can mingle the forces of psychic and physical muscular action in the creation of man can surely give a new life after physical death here, and restore man's personality in the new world that will open out in the Hereafter.
