There are 3 types of bone tissue, including the following:

The nonliving intercellular material of bone consists of an organic component called collagen (a fibrous protein arranged in long strands or bundles similar in structure and organization to the collagen of ligaments, tendons, and skin), with small amounts of proteinpolysaccharides, glycoaminoglycans (formerly known as …

The primary organic components of bone are:

• collagen, the major structural protein (type I in bone and type II in cartilage); and.
• proteoglycans, which are negatively charged glycosylated proteins (glycosylated means having carbohydrate sugar groups modifying the protein).

• Compact tissue. The harder, outer tissue of bones.
• Cancellous tissue. The sponge-like tissue inside bones.
• Subchondral tissue. The smooth tissue at the ends of bones, which is covered with another type of tissue called cartilage.

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.

There are five types of bones in the skeleton: flat, long, short, irregular, and sesamoid.

The bones of the human skeleton are classified by their shape: long bones, short bones, flat bones, sutural bones, sesamoid bones, and irregular bones (Figure 1).

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.

The skeleton

• 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.
• Hands – wrist bones (carpals), metacarpals and phalanges.
• Pelvis – hip bones.

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).

Your bones and muscles work together to support and move your body. Your respiratory system takes in oxygen from the air. It also gets rid of carbon dioxide. Your digestive system absorbs water and nutrients from the food you eat.

A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.

Ligaments: Two bones are connected to each other by a connective tissue called the ligament. This tissue is flexible or elastic in nature. Tendons: Bones are connected to muscles by another type of connective tissue named as Tendons. Tendons are fibrous tissue with great strength but limited flexibility.
