adipose tissue – studies

Adipocyte, I’m looking at your structure. You have everything I understand to be in a human cell plus added oil bodies or lipid bodies. Drawing you out to know you better, I layer the lipid droplets in yellow and white. Fun to resolve this portion of you. I use casein paint and ink but I might have worked with egg tempera. I bet a simple droplet of egg yolk could suffice.

Adipose tissue, AKA body fat, located beneath the skin, around organs, between muscles, in bone marrow and in breast tissue. Can I really describe you as a major endocrine organ because…you produce hormones? Do I understand this correctly? I drew out all the major endocrine glands, do I go back to the series and add you now?

Adipocyte. Fat Cell

Adipocyte AKA Fat Cell

Adipocytes form several types of adipose tissue, at least 2 maybe 3.

One type: Brown adipose tissue (BAT) ↓
Brown adipose tissue, each of your cells includes several lipid droplets. And you hold many iron-containing mitochondria. Is this why you appear warm in color? Mitochondria, holders of energy (ATP), are the power-house of a cell. It is no wonder you consume energy and generate heat.

Brown Adipose Tissue (BAT)

Do you sit in the front and back of the neck and upper back? Between the shoulder blades? Around the kidneys? Anywhere else? And are you the baby-fat in a newborn?

Will you hang out and stay active as I get older? Please do! I need you for warmth and physical activity. I need you for my bones and for endurance.

Second type: White adipose tissue (WAT) ↓
White adipose tissue, I especially enjoy setting in your single lipid droplet (again, like dropping yolk to mix my egg tempera paint).  I pull out my thinnest brushes and sharpen all my pencils to be able to detail organelles into each of your cell’s periphery. You might be simple in design, though I find you more complicated.

White Adipose Tissue (WAT)

You have fewer mitochondria than brown fat. You store energy in case I overexert (and in case of starvation). You too help maintain my body temperature. Do you hold heat? Are you more like insulation? Padding? Are you mostly visceral fat? Might I find you inside my abdominal cavity and between my organs? You don’t have my permission to take over my liver or intestines. And don’t get too comfy with my heart or kidney’s either. You’re a little more troublesome, aren’t you? And what does it mean that you originate from connective tissue?

Maybe a 3rd type is beige fat?
Sooo…I hear white fat can brown with chronic cold exposure. While out on my morning run, I consider the probability. Not happening in Phoenix. Though a friend did just tell me about a local gym that supports a cold therapy.


A few weeks ago:
I have lunch with Joe, a doctor/educator from New Mexico. We meet to discuss the microbiome. He directs the conversation towards weight gain. He says, with no uncertainty, everyone will gain weight with age. He explains why he believes this to be true.

Joe talks about people and the relationship they have with their microbiome which involves both cooperation and conflict. I appreciate when he explains humans are an eco-system. He adds… a sometimes messy eco-system.

The stuff that stays with me:
Weight gain might not always be about discipline or lack thereof.
There might be something else at play in the gaining of weight.
Perhaps gut microbes influence eating behavior.

I sense Joe’s compassion for people dealing with weight issues.

Some play…
I take my drawings through a filter to contrast and simplify forms. Here is another view of the varying density of adipose tissue. #Ahh!Life!

laying out the body human

I carefully outline Carolyn’s form. The first internal organ to come on to the picture plane is the liver. The organ’s communication feels strongest when I set up to paint.

About the liver…
Consider it has over 500 functions! You could not survive without it. The busy organ aids in digestion and metabolism. It filters your blood (1.5 quarts every minute). It breaks down fat (by producing bile) to release it as energy. It also breaks down meds, drugs, alcohol, caffeine…etc. It takes the heat for you every single day! And it stores vitamins, iron and glucose (sorting and hoarding) for a rainy day.

In Chinese medicine the liver is yin (gallbladder is yang). It is like the general of an army. It opens into the eyes, directs the tendons, reflects in the nails, governs anger and houses the ethereal soul. Do you crave sour food? Your liver might be telling you it needs an extra boost.

The Nahuatl understand it to hold one of three vital forces. Ihiyotl governs ones passion, sentiment and vigor. The Ancient Egyptians also believe it seats the emotions. Necessary in the after-life, they preserve it upon death, for safe travel.

I set the notable liver and then I place the heart. Another time I’ll tell you about the Tonalli, another of the vital forces to the Nahuatl.

liver, heart, stomach

I draw the stomach followed by the large intestine, small intestine and colon…

large and small intestines

I detail left breast tissue and right, move to clavicles, arm and hand bones, pelvis, legs and feet bones.

mammary glands

Thyroid (upper blue area in neck) and thymus (lower blue area above heart)

I place the thyroid. The butterfly shaped gland always speaks to me in turquoise blue. At this point I make the heart bigger, overlay it with the thymus gland (also in turquoise) and as is usual when drawing the thymus, I tap mine in acknowledgment.

Spleen

Finally, I introduce the blood vessels and the beautiful lymphatic system into the composition. The latter directs me to outline and color in the spleen. While the spleen associates with the liver – as I paint, it is the most quiet of the organs.

I like the container-like quality about the form. Let’s see if I can keep it.

Side note:
Tucson Museum of Art’s Chief Curator, Julie Sasse, is bringing the TMA’s Latin American Art Patrons to the Phoenix Art Museum’s Teotihuacan exhibition next week. While they’re in town I’ll be hosting a studio visit for them.

A good way to begin the new year…
