what is ligament in detail tell everything about SKELETAL systems and procedures and problems
Answers
Answer:
ligament
Ligaments are short bands of tough, flexible tissue, made up of lots of individual fibres, which connect the bones of the body together. Ligaments can be found connecting most of the bones in the body. The function of a ligament is to provide a passive limit to amount of movement between your bones.
skeleton system
The human skeletal system consists of all of the bones, cartilage, tendons, and ligaments in the body. Altogether, the skeleton makes up about 20 percent of a person’s body weight.
An adult’s skeleton contains 206 bones. Children’s skeletons actually contain more bones because some of them, including those of the skull, fuse together as they grow up.
There are also some differences in the male and female skeleton. The male skeleton is usually longer and has a high bone mass. The female skeleton, on the other hand, has a broader pelvis to accommodate for pregnancy and child birth.
Regardless of age or sex, the skeletal system can be broken down into two parts, known as the axial skeleton and the appendicular skeleton.
functions
The most apparent functions of the skeletal system are the gross functions—those visible by observation. Simply by looking at a person, you can see how the bones support, facilitate movement, and protect the human body.
Just as the steel beams of a building provide a scaffold to support its weight, the bones and cartilage of your skeletal system compose the scaffold that supports the rest of your body. Without the skeletal system, you would be a limp mass of organs, muscle, and skin.
Bones also facilitate movement by serving as points of attachment for your muscles. While some bones only serve as a support for the muscles, others also transmit the forces produced when your muscles contract. From a mechanical point of view, bones act as levers and joints serve as fulcrums (Figure 1). Unless a muscle spans a joint and contracts, a bone is not going to move.

problems
Other common conditions that affect the skeletal system include: Osteoporosis: This is a disease in which the bones become fragile and prone to fracture. Leukemia: This is a cancer of the white blood cells. Osteopenia, osteitis deformans, and osteomalacia: Similar to osteoporosis, these are other types of bone loss.
