Lecture 10 – Final Set of Derivatives

Prefix/Suffix                                        Origin                                     Example

Ultra-                                                   L, beyond                                ultrastructure- the close detail of any cell, with all organelles visible that can be seen with an electron microscope.

Vagina –                                               L, sheath, sleeve, scabbard      vagina – a fibromuscular tubular tract leading from the uterus to the exterior of the body  in female placental mammals.  Often used incorrectly by the general public to describe the vulva or external genitalia, however, the vagina cannot be seen with a casual look.  It is an internal structure.  Anatomically, the female pelvis is my area of research and concentration.  We will discuss the differences between the male and female pelvis in subsequent lectures.

Vas-                                                     L, duct, vessel                          vas deferens – ‘carrying away vessel’ – also called the ductus deferens.  A part of the male anatomy of many vertebrates, these ducts carry the sperm from the epididymis in anticipation of ejaculation.  There are two ducts connecting the left and right epididymis, to the ejaculatory ducts in order to move sperm.  Each duct is about 30 centimeters long in humans and is surrounded by smooth muscle.

Vent- (ventr-)                                       L, belly from Latin venter, which means adbomen                                                                                                                              ventral – on the belly side on a whale or dolphin.  Pertaining to the front or anterior side in a human.  Example – Ventral root ganglion – (to be discussed when we discuss nerves)

Versio-                                                 L, a turning                              anteversion of the uterusa retroverted uterus, or one that is directed ventrally.  Also called a tilted uterus.  This tilting can be in various degrees.

We have many more prefixes and suffixes to explore.  The next set will include as many as 100 terms, but will be in a succinct, list type of format.  Continue to review these terms on a daily basis and make them a part of your routine discussions.  I am very happy that we can spend this time exploring our anatomy.  Your anatomical parts will be with you forever, unless you decide to share them at your demise.  (We will have the conversation about body part donation and transplants at another time.)

We have so much work to do.  I hope you love anatomy as much as I do.  Next time we will delve deeply into our bones, and do a quick review of the metric system.  Once we are done, you never have to be afraid of the metric system!  It is nice to hear from lawyers who are in medical school, and factory workers who are in nursing school.  I applaud you all for following your dreams no matter what your age.  Welcome to the field!  We need people who have a fresh, new perspective.  Many of us have never worked in any other industry, and sometimes share the same points of reference.  Have fun and do extremely well in your science courses.

  1. We absolutely love your blog and find the majority of your post’s to be exactly I’m looking for.
    Does one offer guest writers to write content to suit your
    needs? I wouldn’t mind publishing a post or elaborating on a few of the subjects you write about here. Again, awesome website!
