Livers and internal organs take a bit longer.

From a posterior view again assess for asymmetry, atrophy, or skin changes.

Here's another case that I think is interesting.

The green line goes down. That's the wild nature portion.

Arms amp hands are developing 36 Days

These operations you talked about, were they brain operations?

All vertebrate embryos are inherently female, anyway.

This is Papua, New Guinea.

And so, the year 2000, you see there.

So here's two sort of canonical neurons from a vertebrate and an invertebrate, a human pyramidal neuron from Ramon y Cajal, and another cell to the right, a non spiking interneuron, and this is the work of Alan Watson and Malcolm Burrows many years ago, and Malcolm Burrows came up with a pretty interesting idea based on the fact that this neuron from a locust does not fire action potentials.

I actually understood the mechanics of vertebrae enough to kind of start to imitate them.

I'll just go out in the field and collect these wonderful animals

They said to my parents, the neck break was a stable fracture, but the back was completely crushed.

I just noticed that as I finished this skull, the armature wire that I had been used to holding it up was sticking out of the back just where a spine would be.

Now flight is an inherently difficult thing.

That's a little diver up there in the corner.

Young icefish hide in small ice holes to avoid predators, while a variety of invertebrates,

Or they lay eggs, or they don't lay eggs.

The stork test evaluates for a stress fracture of the pars interarticularis in the lumbar spine.

They die of HlV, they die of hepatitis C, they die of infections of their heart valves, they die of infections of their brains, of their spines, of their hearts, of their bloodstream.

This is the last act on this Earth of a little girl called Heidi, five years old, before she died of cancer to the spine.

Another thing that is interesting is that the brain stem that we have is shared with a variety of other species.

If you don't kill the fish, they take a longer time to die, they grow larger and they reproduce a lot.

If you wrongly move a hurt person and damage the spine, they can become paralyzed completely.

Palpate anatomic landmarks for tenderness.

And so button by button, vertebrae by vertebrae, I built my way down.

And actually, by the end of the day, I had a reasonable skull, a moderately good vertebrae and half of a pelvis.

They start as little eggs, and they're in The Guinness World Book of Records again for having the most number of eggs of any vertebrate on the planet.

Shiitake is a sort of mushroom.

A shiitake is a kind of mushroom.

A shiitake is a type of mushroom.

I'm going to show a clip of one young lady.

I'm a sophomore and studying communications, TV and mass media, and basically trying to live life like a normal kid, which I always wanted growing up.

Anyway, as you'll see in a moment,

(Laughter)

Disk herniation is when cartilage, called 'intervertebral disk' and found between each vertebra, slips out.

So here's how it looks. Look at the region there.

She said, You are, because, see, it happens to everyone.

And the question I asked was, Why me? Why me?

People with spinal cord injuries,

But the only way I can describe what I was seeing that day was that this octopus was playing, which is a pretty sophisticated behavior for a mere invertebrate.

Ten thousand years ago, at the dawn of agriculture, human population, plus livestock and pets, was approximately a tenth of one percent of the terrestrial vertebrate landmass.

And they'll also do it to all the people you represent.

The latest test results show a lost of corneal reflexes.

And the aquarium had a lot of big fish tanks but not a lot of invertebrate displays, and being the spineless guy, I thought, well
