Fat is generally considered to be the softest tissue. Soft tissues are distributed throughout the
The pterion is known as the weakest part of the skull. The anterior division of the middle meningeal artery runs underneath the pterion. Consequently, a traumatic blow to the pterion may rupture the middle meningeal artery causing an epidural haematoma.
Tooth enamel is the first line of defense your teeth have against plaque and cavities. It is the white, visible part of the tooth and it is also the hardest part of the human body.
MOUTH: As is mentioned, since our hands carry most of the disease-causing germs, putting them in your mouth is a big no. Even if your hands are clean, do not put them in your mouth.
Different parts of our body have different temperatures, with the rectum being the warmest (37℃), followed by the ears, urine and the mouth. The armpit (35.9℃) is the coldest part of our body that is usually measured.
The weakest and softest bone in the human is the clavicle or collar bone. Because it is a tiny bone which runs horizontally across your breastbone & collarbone, it is simple to shatter.
The lacrimal bone is perhaps the most fragile bone of the face and one of the smallest bones in the body. Spanning between the middle of each eye socket, each lacrimal is thin and scalelike and serves as support for the eye. The pair of lacrimal bones are two of the fourteen facial bones.
Unbreakable bones – the LRP5 gene
However, a different mutation in the LRP5 gene can also cause an uncommon disorder in which bone density is greatly increased making the bones very strong and resistant to fractures.
The femur is also the strongest bone in your body.
The lacrimal bone, the smallest and most fragile bone of the face, is situated at the front part of the medial wall of the orbit . It has two surfaces and four borders.
Similarly with cold receptors: once the chill drops to frost-bite level, a set of pain receptors takes command. These produce a slow, burning pain; the faster the neurons fire, the more intense the pain. The tongue, lips, and fingertips are the most touch- sensitive parts of the body, the trunk the least.
The Heart – the Hardest Working Muscle.
Kidneys. The kidneys are two bean-shaped organs responsible for filtering the blood and removing waste.
Teeth and bones look similar and share some commonalities, including being the hardest substances in your body. But teeth aren't actually bone. This misconception might arise from the fact that both contain calcium. More than 99 percent of your body's calcium can be found in your bones and teeth.
There's a good reason you've never heard of the fabella, a tiny bone embedded in the tendon of the knee. The bone, whose name means “little bean,” doesn't seem to serve any purpose. Not everyone has one, and people do just fine without it.
The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
Teeth are the ONLY body part that cannot repair themselves. Repairing means either regrowing what was lost or replacing it with scar tissue. Our teeth cannot do that. Our brain for example will not regrow damaged brain cells but can repair an area by laying down other scar-type tissue .
The brain has no nociceptors – the nerves that detect damage or threat of damage to our body and signal this to the spinal cord and brain.
Brains can work 24 hours a day with no rest.
Relaxation, meditation, positive thinking, and other mind-body techniques can help reduce your need for pain medication. Drugs are very good at getting rid of pain, but they often have unpleasant, and even serious, side effects when used for a long time.
The bones that make up your skeleton are all very much alive, growing and changing all the time like other parts of your body. Almost every bone in your body is made of the same materials: The outer surface of bone is called the periosteum (say: pare-ee-OSS-tee-um).
Excerpt. The femur is the longest, heaviest, and strongest bone in the human body.
