The tail vanishes by the time humans are born, and the remaining vertebrae merge to form the coccyx, or tailbone. Tailbones helped our ancestors with mobility and balance, but the tail shrank as humans learned to walk upright. The coccyx now serves no purpose in humans.
Your spine is made up of your vertebrae as well as your spinal cord and associated nerves. It's vital to your overall health and functioning, and you can't live without it.
The one exception is the hyoid bone. The U-shaped hyoid bone sits at the base of the tongue and is held in place by muscles and ligaments from the base of the skull and jaw bones above.
The clavicle, or collar bone, is the skin's softest and weakest bone.
Your thighbone (femur) is the longest and strongest bone in your body. Because the femur is so strong, it usually takes a lot of force to break it. Motor vehicle collisions, for example, are the number one cause of femur fractures.
The lacrimal bone is one of the smallest and most fragile bones of the face. Despite its small size - a little bigger than the size of a fingernail - it has a complex anatomy, with several bony landmarks that are essential for the process of tear formation and secretion.
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.
Famously, the hyoid bone is the only bone in humans that does not articulate with any other bone, but only has muscular, ligamentous, and cartilaginous attachments.
The only bones that continue to get larger are the skull and the pelvis. The growth of these two body parts isn't dramatic, however. Your pelvis might gain an inch in diameter between the ages of 20 and 79, and your skull may get slightly more prominent around the forehead.
The only part of the body that cannot repair itself is the tooth. The tooth cannot replace or repair itself in humans. Human teeth don't have the cells necessary to repair damages like other organs and structures do.
Types of Organs in a Human Body
Altogether there are seventy-eight main organs within the human body. These organs work in coordination to give rise to several organ systems. Among these 78 organs, five organs are considered vital for survival. These include the heart, brain, kidneys, liver and lungs.
The femur is also the strongest bone in your body. It can support as much as 30 times the weight of your body.
It is an S-shaped bone. The clavicles are located on each side of the chest. The clavicle is known as the "beauty bone" because of its location in the body.
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. Water makes up 31% of the weight of your bones.
INTRODUCTION. Not surprisingly, lower initial stability and higher failure rates of implantation into poor quality bone, as opposed to higher quality bone, are well documented. Notably, the poorest bone quality in the oral environment typically exists in the posterior maxilla.
The orbital roof consists of two parts of two bones, the orbital plate frontal bone and the lesser wing of the sphenoid bone. The fossa of the lacrimal gland is in the orbital roof, and it lies anteriorly and laterally behind the zygomatic process of the frontal bone.
A fracture of the upper arm or humerus may heal uneventfully in several weeks, while a fracture in the forearm takes much longer. The femur, or thighbone, is the longest and strongest bone in the body and difficult to break without major trauma.
Pancreas
The pancreas regulates blood sugar levels and secretes enzymes that help the intestines absorb nutrients from digested food. Alongside the spleen, it is one of the heaviest organs in the digestive system.
