Bones are semi-rigid, porous, mineralized organs, consisting of cells in a hard matrix, that form part of the endoskeleton of vertebrates. Bones function to move, support, and protect the body , produce red and white blood cells, and store minerals.
What are 2 characteristics of irregular bones?
Irregular bones have complex, irregular shapes and do not fit into any other category of bone . Many irregular bones are short, flat, notched, or ridged, with extensions that protrude from their many bone parts.
What are the two characteristics of bones?
They are lightweight yet strong and hard , and serve multiple functions. Bone tissue (osseous tissue) is a hard tissue, a type of specialized connective tissue. It has a honeycomb-like matrix internally, which helps to give the bone rigidity. Bone tissue is made up of different types of bone cells.
What are 3 facts about bones?
- The adult human body has 206 of them.
- There are 26 bones in the human foot.
- The human hand, including the wrist, contains 54 bones.
- The femur, or thighbone, is the longest and strongest bone of the human skeleton.
What are the main characteristics of bone?
Bones are semi-rigid, porous, mineralized organs, consisting of cells in a hard matrix, that form part of the endoskeleton of vertebrates. Bones function to move, support, and protect the body , produce red and white blood cells, and store minerals.
What are some characteristics of bones?
Bones are semi-rigid, porous, mineralized organs, consisting of cells in a hard matrix, that form part of the endoskeleton of vertebrates. Bones function to move, support, and protect the body , produce red and white blood cells, and store minerals.
What are the two types of bone and what are their features?
Compact (cortical) bone : A hard outer layer that is dense, strong, and durable. It makes up around 80 percent of adult bone mass. 2. Cancellous (trabecular or spongy) bone: This consists of a network of trabeculae or rod-like structures.
What is the function of irregular bones?
Like flat bones, the function of irregular bones is to protect various parts of your body . For example, your vertebrae protect your spinal cord.
What is the function of flat bones?
Flat bones are a type of bone in your body. They’re typically thin, flattened, and slightly curved. Flat bones serve to either protect your internal organs or to provide a connection point for your muscles .
What’s the shortest bone in human body?
At 3 mm x 2.5 mm, the “stapes” in the middle ear is the smallest named bone in the human body. The shape of a stirrup, this bone is one of three in the middle ear, collectively known as the ossicles.
What is the weakest bone in your body?
Clavicle : Clavicle, or collar bone, is the body’s softest and weakest bone. It is easy to break since it is a thin bone that runs horizontally between your breastbone and shoulder blade.
What is the strongest bone in your body?
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.
What is bone and its types?
The bones of the body come in a variety of sizes and shapes. 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.
What is bone and its function?
The skeleton is an important organ for the support of the body and for the attachment of muscles and tendons , as well as body movement. The skeleton protects the organs of the cranial and thoracic cavities from injuries, and it houses and protects the bone marrow within its cavities.
What are the four components of bone?
The skeletal system includes four basic components, although some sources include a fifth, the joints. The four are the bones, which make up most of the mass of the skeletal system; cartilage, which acts mainly as padding; ligaments, which usually connect bones to bones ; and tendons, which join muscles to bones.
Where is bone found?
The adult human skeleton is made up of 206 bones. These include the bones of the skull, spine (vertebrae), ribs, arms and legs . Bones are made of connective tissue reinforced with calcium and specialised bone cells. Most bones also contain bone marrow, where blood cells are made.
