Final answer:
The Dartos muscle is not part of the spermatic cord; the cord consists of the cremaster muscle, testicular artery, ductus deferens, and pampiniform plexus.
Step-by-step explanation:
The component of the spermatic cord that is not a part is the Dartos muscle. The spermatic cord consists of the cremaster muscle, testicular artery, ductus deferens (also known as vas deferens), and pampiniform plexus. While the dartos muscle is located in the scrotal wall and serves to regulate temperature by contracting or relaxing in response to environmental temperatures, it is not part of the spermatic cord itself.
