Human teeth are made up of four different types of tissue: pulp, dentin, enamel, and cementum. The pulp is the innermost portion of the tooth and consists of connective tissue , nerves, and blood vessels, which nourish the tooth.

Teeth are not bones. Yes, both are white in color and they do indeed store calcium, but that’s where their similarities end.

Bone – Unlike your bone material, enamel does not contain collagen. Hair and Fingernails – Like hair and fingernails, tooth enamel contains keratin, but in significantly less levels, teeth are not considered the same makeup as hair or fingernails.

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.

Treatments ranging from casting to surgery can be required. Unfortunately, the scaphoid bone has a track record of being the slowest or one of hardest bones to heal.

The human skeleton is made up of 206 bones, including bones of the:

• Skull – including the jaw bone.
• Spine – cervical, thoracic and lumbar vertebrae, sacrum and tailbone (coccyx)
• Chest – ribs and breastbone (sternum)
• Arms – shoulder blade (scapula), collar bone (clavicle), humerus, radius and ulna.

The femur is one of the most well-described bones of the human skeleton in fields ranging from clinical anatomy to forensic medicine. Because it is the longest and strongest bone in the human body, and thus, one of the most well-preserved in skeletal remains, it makes the greatest contribution to archaeology.

There are generally three levels of identification that can be utilized to distinguish between human and non-human animal bones: 1) gross skeletal anatomy, 2) bone macrostructure, and 3) bone microstructure (histology).

The porous nature of some fossil bones will cause it to slightly stick to your tongue if you lick it, though you might want to have a glass of water handy if you feel compelled to try this.

However, the pelvis is the best sex-related skeletal indicator, because of distinct features adapted for childbearing. The skull also has features that can indicate sex, though slightly less reliably. The differences between a male and female pelvis are compared below.

The inside of your bones are filled with a soft tissue called marrow. There are two types of bone marrow: red and yellow. Red bone marrow is where all new red blood cells, white blood cells, and platelets are made. The bone marrow of full grown adults is about half red and half yellow.

Bones are strong and even have some give to them, but they have their limits, too. They can even bleed after a serious break. Diseases like cancer and osteoporosis can also lead to breaks because they make your bones weaker and more fragile.

Every single person has a skeleton made up of many bones. These bones give your body structure, let you move in many ways, protect your internal organs, and more. It’s time to look at all your bones — the adult human body has 206 of them!

stapes

The skin

1. The femur bone is the longest and strongest bone in the body. Located in the thigh, it spans the hip and knee joints and helps maintain upright posture by supporting the skeleton.

The stapes is the smallest and lightest bone in the human body, and is so-called because of its resemblance to a stirrup (Latin: Stapes)….

Long Bones Support Weight and Facilitate Movement The long bones, longer than they are wide, include the femur (the longest bone in the body) as well as relatively small bones in the fingers.
