Study Notes

Vermiform Appendix Characteristics

  • The vermiform appendix is a blind muscular tube comprising mucosal, submucosal, muscular, and serosal layers.
  • It is considered an undeveloped distal end of the large cecum, which is present in many lower animals.

Length and Variation

  • Length of the vermiform appendix typically varies from 3 to 5 inches (8 to 13 cm).

Position

  • The appendix's most common positions include retrocaecal (74%), pelvic (21%), subcaecal (1.5%), paracaecal (2%), preileal (1%), and postileal (0.5%).

Attachment and Location

  • The base of the vermiform appendix is attached to the surface of the cecum roughly 1 inch (2.5 cm) below the ileocecal junction.

Overall Classification

  • The vermiform appendix is recognized as a part of the large intestine.
  • In many lower animals, the vermiform appendix is a developed organ, unlike its reduced form in humans.
