How To: Dissect a human to see the split pelvis

If you want to know more about the science of the human body, just stop right here at this video tutorial on the dissection of the perineum. This anatomical look at the pelvic outlet will show you right down to the bone, then will show you the osteology of the split pelvis, which is a pelvis in which the symphysis pubis is absent and the pelvic bones are separated, usually associated with exstrophy of the bladder. You'll check out both female and male pelvic regions in this educational look a...

How To: Dissect a human to see the pelvic outlet

If you failed your anatomy class in that medical college you so dearly paid for, you might want to think about taking it again. To help you out, just watch this video tutorial on dissecting a human, concentrating on the pelvic outlet. So, get out your scalpel and learn how to cut away to the bladder and the pelvic outlet, in which we see a split pelvis, which is a pelvis in which the symphysis pubis is absent and the pelvic bones are separated, usually associated with exstrophy of the bladder.

How To: Dissect a human to see the abdominal autonomics

Need to check out the posterior abdominal wall of a human being? Well, go no further. This human anatomy video tutorial will show you how to dissect a human for a closer look at the abdominal autonomics, the genital and urinary systems, the diaphragm, and the posterior abdominal wall. You need to get most of the superficial layers out of the way, so get your scalpel out and get cutting. You'll even check out the kidney itself in this educational look at the insides of a corpse.

How To: Dissect a human to see the organs in the thorax

The science of the human body is a glorious thing, and educating yourself through its anatomy is a great way to learn. Here you'll learn how to dissect a human to see the organs in the thoracic cavity. You'll also see the lungs and pleural sacs, and the heart and pericardial sacs in the thorax. So, cut out that heart and lungs with a scalpel or knife and extract it for a closer anatomical look. This video tutorial is all you'll need to pass anatomy 101.

How To: Dissect a human to see the superficial layers of skin

Before you start dissecting the body of a human being, there are a few things you should probably learn first. This anatomical look at the human body will give you just what you need to delve into your human dissection. Just watch this video tutorial on a few bony landmarks you should be aware of by palpating, like the clavicles, the sternum and sternal notch, the rib cage, and the pelvic region.

How To: Turn spinach from green to glowing red

Chlorophyll glows blood red under a black light. Here is an easy and cheap experiment you can do at home to see the results. Just check out this video tutorial to learn how to take a handful of green spinach, some rubbing alcohol, and a blender to prep the amazing red glowing liquid.

You'll get all of the names associated with the sheep brain, but don't think you'll remember them in one sitting, there's too much for even the über-science nerd.

How To: Grasp the anatomy of the lumbosacral plexus in humans

Check out this terrific educational video series on the anatomy of the lumbosacral plexus of the human body. You'll learn about the anterior divisions of the lumbar nerve, sacral nerve, and coccygeal nerves, which form the lumbosacral plexus. This anatomy filled video will cover the lumbar plexus, sacral plexus, and the pudendal plexus. There's so much to learn from this that I can't even try to write it all down. Just be sure that you could be one hell of biologist if you watch. Maybe even a...

How To: Grasp and calculate human blood pressure regulation

Check out this science-filled two-part video tutorial on blood pressure regulation in humans. This educational video will show you the MABP (mean arterial blood pressure), which is the overall blood pressure in your body, the TPR (total peripheral resistance), and the CO (cardiac output). You won't just learn about the blood pressure, you'll see how to calculate the MABP. You'll be fascinated, whether you're a physiologist, biologist, scientist, medical student, or just an human anatomy nut.

How To: Grasp the human physiology of the heart

How To: Use a Peltier module to create free electricity from heat

A Peltier module allows you to turn heat into electricity. Because you can place it in areas that are normally warm anyway, the electricity created is "free" in a sense, though it does work best when one side of the module is cold and the other is hot. In other words, all you'll need for this project is the Peltier module and a cooler surface such as soil or water, and a warm area such as a well lit window or warm pan.
