Is Anatomy Finished? | A Review of New Discoveries | TAPP 105


Are there really no more discoveries in human anatomy? In this episode, I'll review some recent discoveries: the rise of the fabella, macrophage barriers, the interstitium, button and zipper junctions, lymph node micro-organs, new vessels in bones, and tubarial salivary glands.

Is Anatomy Finished?

3 minutes

It's easy to fall into that mindset that anatomy is "finished"—that there are no new discoveries to be made in the structure of the human body. But that's simply not the case. In this episode, Kevin reviews seven anatomical discoveries discussed in the last few years of this podcast.

Rise of the Fabella

7.5 minutes

The fabella (pl., fabellae) is a small, beanlike bone that may (or not) occur behind the knee joint. Recent evidence shows that it's showing up  more frequently in the population. Why?

T★ he original version of this segment aired in Anatomic Variations in Humans | Fabella | Situs Inversus | Episode 43

★ Fabella prevalence rate increases over 150 years, and rates of other sesamoid bones remain constant: a systematic review (recent research article) my-ap.us/2WkRSMs

★ Sore knee? Maybe you have a fabella (plain English report from the BBC) my-ap.us/2Wmd6cN

★ Fabella x-radiograph (to use in your course) my-ap.us/2Wm6Di3

Barrier Macrophages

10.5 minutes

We knew there were macrophages within, and upon, the synovial membrane that lines synovial joints. What we have just learned is that macrophages on the synovial membrane surface can bind with tight junctions to form a barrier layer. Go figure.

★ The original version of this segment aired in More on Spelling, Case, & Grammar | Episode 56

Interstitium

3.5 minutes

Has a new human organ discovered? Or is this news mostly hype? Or is the answer somewhere in the middle?

★ The original version of this segment first aired in Test Debriefing Boosts Student Learning | Episode 11

Structure and Distribution of an Unrecognized Interstitium in Human Tissues (original research report)

Newly-discovered human organ may help explain how cancer spreads (article about the original report)

That “New Organ” Everyone Is Freaking Out About Is Probably Not New (article outlining criticism of the original report)

Is the Interstitium Really a New Organ? (another article interprets the original report)

Is This Tissue a New Organ? Maybe. A Conduit for Cancer? It Seems Likely. (yet another opinion)

Button and Zipper Junctions

7.5 minutes

Are you familiar with the button junctions that connect overlapping endothelial cells in lymphatic capillaries in a way that forms valves? What about zippers? Where do they fit into the story? (They do.) Here are some links to the details behind a great demo that Kevin shares for understanding lymphatic structure and function.

★ The original version of this segment aired in Promoting Academic Integrity in Our Course | Episode 25

Functionally specialized junctions between endothelial cells of lymphatic vessels (2007 research article outlining button and zipper junctions; great images)

Plasticity of button-like junctions in the endothelium of airway lymphatics in development and inflammation. (2012 research article shows that zippers predominate in early development, but are then convert to buttons; also has some really cool images showing these junctions)

Lacteal junction zippering protects against diet-induced obesity (2018 research article)

★ ★ Tighter lymphatic junctions prevent obesity (perspective and summary of the research article; includes a nice slide you can use in teaching)

Lymphatic Micro-Organ

4.5 minutes

One headline announced the discovering of a new human micro-organ. It turns out, researchers have found a distinct structure just beneath the capsule of lymph nodes called the subcapsular proliferative focus (SPF) where memory B cells hang out—not deep in the germinal center (GC).  This puts them in a good position to be activated by macrophages acting as antigen-presenting cells (APCs) and mount a strong secondary immune response.

★ The original version of this segment first aired in Modeling Professional Integrity | Episode 26

Researchers Discover New ‘Micro-Organ’ in Human Immune System (news item about the discovery)

New Vessels in Bone

3.5 minutes

Scientists have discovered a system of small vessels that cross every part of a bone's cortical layers to supply most of the bone's blood—over 80% of the arterial supply and 59% of venous drainage. The proposed name is trans-cortical vessels (TCVs).

★ The original version of this segment aired in Big Year in Anatomy & Physiology Teaching with The A&P Professor | Episode 36

★ We’ve discovered a new type of blood vessel in our bones (brief article summarizing the discovery) my-ap.us/2B6tHce

★ A network of trans-cortical capillaries as mainstay for blood circulation in long bones (full research article) my-ap.us/2B6ttSq

★ Video (gif) showing a virtual trip through a TCV my-ap.us/2B6XX6H

 

Tubarial Salivary Glands

8 minutes

A recent paper proposes the existence of a new organ—the paired tubarial salivary gland. It's suggested that this be added as a major salivary gland along with the parotid, submandibular, and submaxillary salivary glands.

★ The original version of this segment aired in New Organ | Dam Protons | Our Secret Language | TAPP 80

★ The tubarial salivary glands: A potential new organ at risk for radiotherapy (original research article) my-ap.us/3khGFZe

Should Students Change Answers? | Journal Club with Krista Rompolski | TAPP 104


Krista Rompolski joins us for another Journal Club episode—bringing us a study about how students change answers on their tests. Is it better for a student to change their multiple choice response or to avoid doing that? The answer may surprise you!
