What are the different types of bones?
The four principal types of bones are long, short, flat and irregular.
Bones that are longer than they are wide are called long bones.
They consist of a long shaft with two bulky ends or extremities.
They are primarily compact bone but may have a large amount of spongy bone at the ends or extremities..
What are the irregular bones in the body?
The irregular bones are: the vertebræ, sacrum, coccyx, temporal, sphenoid, ethmoid, zygomatic, maxilla, mandible, palatine, inferior nasal concha, and hyoid.
What are the 2 types of bone?
There are two types of bone tissue: compact and spongy. The names imply that the two types differ in density, or how tightly the tissue is packed together.
Where are all 206 bones in the human body?
The axial skeleton, comprising the spine, chest and head, contains 80 bones. The appendicular skeleton, comprising the arms and legs, including the shoulder and pelvic girdles, contains 126 bones, bringing the total for the entire skeleton to 206 bones.

What is the weakest bone in the human body?
The weakest bone in the human body is the spine or spinal cord, or sometimes it can be the nose as well. The weakest bone is the ethmoid bone in the nasal region as it is paper thin. The stapes in the middle ear is very delicate too and the body’s smallest bone.
What bone is hardest to break?
The femur, or thigh bone, is the toughest bone in the body to break. It’s the largest and thickest bone, for two things, and it’s also protected by all those leg muscles. The collarbone, conversely, is relatively small and close to the surface of the skin, and therefore is one of the most commonly broken bones.
Are teeth bones?
Are Teeth Considered Bones? 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.
What are the 5 types of bones?
There are five types of bones in the skeleton: flat, long, short, irregular, and sesamoid. Let’s go through each type and see examples.
What is the longest bone in the body?
femurThe femur is one of the most researched bones in the human anatomy and forensic medicine. As the longest bone in the human body, it is well preserved in skeletal remains.
What type of bone is humerus?
long bonesYour humerus is classified as a long bone. Other types of long bones include the radius and ulna in your forearm and the femur in your upper leg.
What type of bone is temporal?
The temporal bone is a thick, hard bone that forms part of the side and base of the skull. This bone protects nerves and structures in the ear that control hearing and balance.
What are the major bones of the body?
The skeletonSkull – 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.Hands – wrist bones (carpals), metacarpals and phalanges.Pelvis – hip bones.More items…•
What are bone cells called?
Bone is composed of four different cell types; osteoblasts, osteocytes, osteoclasts and bone lining cells. Osteoblasts, bone lining cells and osteoclasts are present on bone surfaces and are derived from local mesenchymal cells called progenitor cells.
Which bone is the longest and strongest bone in the human body?
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. 2. The humerus bone is in the upper arm and spans the shoulder and elbow joints.
What is the difference between long and short bones?
Long bones, such as the femur, are longer than they are wide. Short bones, such as the carpals, are approximately equal in length, width, and thickness. Flat bones are thin, but are often curved, such as the ribs. Irregular bones such as those of the face have no characteristic shape.
What is the largest and smallest bone of human body?
The smallest bone in the human body is a tiny middle-ear bone called the stapes, or stirrup bone. The largest one is the femur, or thigh bone (pictured here). It’s also the longest, heaviest, and strongest bone — it supports much of your weight.
Which bone is known as Beauty Bone?
The beauty bone is mostly just another name for your collarbone or clavicle, in women, especially. It is the bone located above the ribs in the chest. Like the ribs, the clavicle is attached to the sternum, sometimes also known as the breast bone, on its medial end.
What are short bones?
Short bones are shaped roughly as a cube and contain mostly spongy bone. The outside surface is comprised of a thin layer of compact bone. Short bones are located in the hands and feet. The patella (kneecap) is also considered a short bone.
What is long bone in human body?
Long bones are hard, dense bones that provide strength, structure, and mobility. The thigh bone (femur) is a long bone. A long bone has a shaft and two ends. Some bones in the fingers are classified as long bones, even though they are short in length.
What is a Osteon?
Osteon, the chief structural unit of compact (cortical) bone, consisting of concentric bone layers called lamellae, which surround a long hollow passageway, the Haversian canal (named for Clopton Havers, a 17th-century English physician).
