The Muscular System

The Organs That Make Up The Muscular System

The different organs in the muscular system include cardiac muscles, smooth muscles and skeletal muscles. A complete muscle — consisting of muscle fibers, connective tissue, nerve tissue and blood tissue — is considered one organ by itself. There are roughly 600 organs in the muscular system, and these muscles make up about 40 percent of the body. These organs can be divided into four major groups: the muscles of the lower extremity, the trunk muscles, the muscles of the upper extremity and head-and-neck muscles. Most of these structures are connected by tendons.

Cerebral Palsy

Cerebral palsy is a group of problems that affect body movement and posture. It is related to a brain injury or to problems with brain development. It is one of the most common causes of lasting disability in children.

Cerebral palsy causes reflex movements that a person can't control and muscle tightness that may affect parts or all of the body. These problems can range from mild to severe. Intellectual disability, seizures, and vision and hearing problems can occur.

Cerebral palsy is caused by a brain injury or problem that occurs during pregnancy or birth or within the first 2 to 3 years of a child's life. It can be caused by:

  • Problems from being born too early (premature birth).
  • Not getting enough blood, oxygen, or other nutrients before or during birth.
  • A serious head injury.
  • A serious infection that can affect the brain, such as meningitis.
  • Some problems passed from parent to child (genetic conditions) that affect brain development.

In many cases, the exact cause of cerebral palsy is not known.

More About Cerebral Palsy

Even though cerebral palsy can't be cured, you and your child can do things to help deal with symptoms, prevent problems, and make the most of your child's abilities. Physical therapy is one of the most important treatments. Medicines, surgery, and special equipment such as a walker can also help.
