Fun Fact: Posterior Median Furrow

Anatomy Def: Midline vertical depression in the surface of the back (red arrows).

Outlander Def:  Deep, lovely groove of Jamie’s back!  

Get in the groove and Learn about Jamie’s back furrow by reading Anatomy Lesson #10, Jamie’s Back!

The posterior median furrow (PMF) literally means “back middle groove.” This vertical depression is most visible in thoracic and lumbar regions of the back. It tends to be shallow in the cervical region, diminishes over the sacrum and is continuous with the gluteal cleft (Aye, the sweet cheeks! <G>).

PMF is most visible in those with robust para-spinal (erector spinae) muscles. These muscles flank the vertebral column; the more developed the muscles, the deeper the PMF.

PMF is useful during physical exam because the vertebral spines can be palpated and counted in the groove. Specific vertebral spines mark levels for anesthesia delivery, location of abdominal organs, and vascular anatomy. For example, C3 marks the level of the hyoid bone (wink, wink to book readers).

More Fun Facts: English is replete with idioms about the back. These are  a few of the many:

  • Back away
  • Back me up
  • Back and forth
  • Back to square one
  • Back in the day
  • Back to the drawing board
  • Back down from
  • Back the wrong horse
  • Back to back
  • Back in circulation

Read about Jamie’s posterior median furrow in Outlander book. Yes, Herself describes it! 👏🏻👏🏻👏🏻

Compassionate Claire notes the groove as she describes Jamie’s badly damaged back: 

He sat patiently, not moving as I circled behind him and inspected his back…I was appalled…The scars covered his entire back from shoulders to waist. While many had faded to little more than thin white lines, the worst formed thick silver wedges, cutting across the smooth muscles. I thought with some regret that it must have been quite a beautiful back at one time. His skin was fair and fresh, and the lines of bone and muscle were still solid and graceful, the shoulders flat and square-set and the backbone a smooth, straight groove cut deep between the rounded columns of muscle that rose on either side of it…I tried not to imagine the muscular arms raised…ropes cutting into wrists, the coppery head pressed hard against the post in agony…Involuntarily, I reached out, as though I might heal him with a touch and erase the marks with my fingers. He sighed deeply, but didn’t move as I traced the deep scars, one by one, as though to show him the extent of the damage he couldn’t see.

Och! See Jamie’s PMF in Outlander, episode 105, Rent, after Uncle Dougal rends Jamie’s sark to expose BJR’s handiwork! 😱 Back off, Dougal!

Fun Fact: Tendinous Intersection

Anatomy Def: Tendinous intersections are fibrous bands crossing the rectus abdominis muscles and marked by overlying skin grooves (curved red arrow).

Outlander Def: Belly grooves defining Jamie’s six-pack. Woot!

Learn about tendinous intersections (TAs) in Anatomy Lesson #16, Jamie’s Belly or Scottish Six-Pack.

Skin grooves overlying TAs are typically visible only in the lean and fit. Most humans have three pair:

    • Pair near tip of breastbone (xiphoid process),
    • Pair at navel
    • Pair midway between xiphoid and navel

Anatomical Variations:

  • TAs may be  horizontal, zigzag, arched or oblique
  • TA may be offset relative to its partner
  • Partial TAs are common (see Jamies top L groove)
  • 4th (& 5th) TA pairs may occur but usually incomplete
  • Extra TA pairs produce  an eight-pack

Question: Why do we have TAs? Are they for beauty or are they useful? Turns out, they are extremely useful.

As rectus abdominis muscles contract, the torso draws nearer the lower body. This is forward flexion. TAs allow rectus abdominis muscles to contract in segments permitting greater control over the degree of forward flexion.

Without TAs, there would be one long rectus abdominis on each side. Reduced strength can be predicted along with reduced control over the degree of forward flexion.

Does this ever happen? There is one report in the literature of a man who died at 64. Subsequent dissection revealed he had no TAs in either rectus abdominis muscle, so clearly, one can survive without these interesting structures.

Fun Fact:  are studied because the rectus abdominis muscle is used in reconstructive surgeries, especially those involving the breast.

Read about Jamie’s belly in Outlander book. Here’s Claire’s “frank” (Isn’t he 200 years away?) appraisal of Jamie on their wedding night:

“Take off your shirt,” I said, sitting up and pulling at the hem of the garment.

“Why?” he asked, but sat up and obliged. I knelt in front of him, admiring his naked body.

” ‘Because I want to look at you,’ I said.

He was beautifully made, with long graceful bones and flat muscles that flowed smoothly from the curves of chest and shoulder to the slight concavities of belly and thigh.”

See Jamie’s beautiful belly with its tendinous intersections in the above  publicity photo.

‘Nuff said!

2019 SiWC & Outlandish Vancouver, Day 3

Hi Outlander fans!

Last day at Surrey International Writers’ Conference (SiWC) and Outlandish Vancouver; things to do at both events.

I arrive early for Diana’s SiWC workshop, Managing a Mob, and take a moment to get my microphone set up. I am very excited.

This workshop was scheduled for 2018 SiWC, but was cancelled  when Diana was called to NYC for the PBS’ Great American Read. You may recall, To Kill A Mocking Bird took first place. Outlander book took second place! … beating out Pride and Prejudice. Puir Mr. Darcey! <G>

But, good news! SiWC rescheduled Herself’s Managing a Mob workshop for 2019, and the presentation was worth the wait! I recorded the entire session including Q and A, and share it (with her permission). Here it is in its entirety. To listen, click on the white arrowhead and wait for it to load. So, grab a cuppa and enjoy! 👍🏻

A quick lunch with Diana. She accommodated my request to photograph her beautiful nails. These are not gels, but regular polish. Love the electric violet! They also don’t interfere with keyboard work as she “types” with fingertips (I asked 😜).

What did we talk about? Nails, femurs, medial condyles, grandchildren (her little grandsons are gorgeous!), Season 4, Season 5 (she is enthusiastic)! Yay!

I gifted Diana with one of my beaded pieces.  This “Queen Bee” honors big book nine, Go Tell The Bees That I Am Gone. A queen bee can be recognized by its elongated abdomen.

You may note that the upper left wing is upside down. I didn’t notice until it was stitched in place. I started to correct and then changed my mind  – only the Divine is perfect! 😉

A quick hug, goodbye, and off to meet Courtney Williams of Outlanderbts. We drove together to the final Outlandish Vancouver event, Cocktails with the Cast!

We are bound for the Native, a paddlewheeler on the beautiful Fraser River, New Westminster, B. C.

Diana and all the invited cast members, except John, were able to attend. We missed ye, lad!

Here are the guests, up close and looking, oh, so fine!

Paddlewheels start turning and we are off!

After drinks and hors de oeuvres, there is a splendid moment: Diana officiates in renewing wedding vows for this Texas couple! I am sure many of you recognize them as they are devoted Outlander fans. Few dry eyes as Diana recited “Ye Are Blood of my Blood, and Bone of My Bone!” Congratulations to Mark and Tina on 40 years of wedded bliss!

My view from the upper deck as the sun is setting. A tug tows log booms behind it. Then, the tug sounds its horn in greeting! (Pardon the fingers 😜)  Stunning!

Later, Koko informs us that Diana is helming (not driving) the boat!

A beautiful moment for her, I am sure. Diana does a seamless job as pilot – we didn’t know Herself was skillfully guiding us through the water. The next is one of my all time favorite photos of Diana! 🥰

Being petite, she cannot see over the wheel, but between the spokes works!

After docking, I grabbed Courtney and we scurried back to Surrey! She called me later that night to ask if my refrigerator was running? Silly girl! 😜

Just so you ken, Outlandish Vancouver is the brain child of Koko Pipkin. In the photo below, she is surrounded by the cast (she is also petite).

I don’t believe I have ever been to a fan event that ran as smoothly as this. Everyone was friendly, helpful, and organized.

Case in point: As I was shaking Mark’s hand, a small plate slipped out of my hand and shattered on the deck of the Native. Gah! 😱 Koko was there to pick up the pieces before I even bent down. Thank you, Koko!

Next year’s date is penciled into my calendar. Plan to be there come heck or high water!!! 😁

The deeply grateful,
