How is everything?! I wanted to share with all of you an AWESOME exhibit that I went to the other day. It’s called Body Worlds Vital and is currently in Rhode Island — I believe until January — so those of you that are in the area, I highly recommend you check it out. It’s relatively inexpensive and you’ll definitely learn something from it.
For those of you not in Rhode Island, keep an eye on where they go next. It travels all over the world and hopefully will come to you! If not, read on, as I will share some pictures and fun factoids. Happy learning!
Above is the “Orthopedic Body”, posed as a dancer. It is fitted with various artificial joints. Orthopedics corrects skeletal deformities.
Directly above is the “Skin Man”. The skin is our largest and heaviest organ. Despite being a few millimeters thick, we cannot obviously survive without it. It protects us from micro-organisms, stops us from drying out, regulates our temperature and provides information about how the outside world feels. Ageing of our skin happens when special elastic fibres within it are damaged. This causes the skin to lose its youthful recoil and stay in permanent wrinkles. The main cause of elastic fibre damage is UV light from the fun. This is why tanning, however good it may look in the short term, actually speeds up the ageing process -_- Repeated exposure to cigarette smoke alos seems to damage skin over time and enhance wrinkling.
Directly above is a cross-section of a Thoracic Cavity. The bronchial passages in the lungs lead into clusters of tiny air sacs (alveoli) that give the lungs a sponge-like appearance. Each alveolus is surrounded by a network of capillaries where oxygen and carbon dioxide are exchanged. Each lung contains 300-450 million alveoli. Spread out flat, they would cover an area of about 850-1,300 square feet.
Pretty neat, right?! Some other interesting tidbits of knowledge I picked up:
- The human hand has 27 bones, controlled by 37 skeletal muscles. They allow for a wide variety of movement with exceptionally fine control and a powerful gripping action. In particular, it is our ability to bring the tips of our thumb and fingers together that gives human hands their unique dexterity.
- That “pins and needles” sensation you get is usually caused by sitting or lying in a way that restricts the blood supply to the area. Normal feeling is restored by changing position and letting the blood back in. The numbness is replaced y that prickling sensation, as the nerves wake up again and start sending messages to the brain and spinal cord.
- The knee joint bones are not a perfect fit. To fill the gap, they have two crescent-shaped cartilage wedges called menisci. Only the outer edges are supplied with blood and therefore regenerate poorly following an injury.
- A muscle can only shorten and relax. When we move, different muscles act on opposite sides of a joint, pulling it in different directions in which it can move. For example, the biceps flexes the elbow, while the triceps at the back of our arm does the opposite and extends the elbow. When the biceps contracts, balancing activity in the triceps inhibits excessive movement. This makes our movements fluid and controlled.
- The cerebrum is the largest part of our brain. Almost two thirds of the brain’s surface are hidden in the furrows. Spread out flat, the cerebral cortex would cover about 16 square feet.
- The biggest risk factors of a stroke are high blood pressure, diabetes, smoking, obesity and high cholesterol levels.
- Twins are conceived when a fertilized egg divides into two embryos or two fertilized eggs develop simultaneously. In the former case, the twins share the same genetic code and are identical twins. They are always of the same sex. In the second case, the twins are fraternal. They are genetically as similar or different as any other non-identical siblings and always have their own placenta.
Now you know! The body is an amazingly wonderful thing and I love learning more about it. Treat yours well 🙂
