Locomotor apparatus


The locomotor system or apparatus consists of the skeleton , joints and muscles that our body has. The skeleton and muscles give more or less shape to the body, although the fat between the skin and the underlying muscle alters the contours of the body, and the contents of a cavity, such as the thoracic and abdominal cavities , influence the shape of the chest and the abdomen . The presence of the jointsDefined simply as the various joints between bones, it allows one bone to move over another and these movements are caused by the muscles. The contraction of muscles and the coordination of movements are examples of how impossible it is to separate one system from another. Properly functioning vascular and nervous systems are essential for proper muscle function .


What is the musculoskeletal system?

It is the set of structures that allow the human body to perform any type of movement . This apparatus is made up of the skeleton or bone system and the muscular system .

Characteristics of the locomotor system

The main characteristics of the musculoskeletal system are the following:

  • The main part of the musculoskeletal system is the skeleton, which is made up of rigid, hard, white bones.
  • Provides support to the body.
  • It is also formed by the joints.
  • It depends on the nervous system, mainly the peripheral one .
  • It is a system of voluntary movement.


The main functions of the musculoskeletal system are:

  • It allows humans and vertebrate animals to be able to relate to the environment that surrounds them.
  • Proper body movement.
  • It forms the main cavities in the human body where the organs lie.
  • They provide support and resistance.
  • Protects the internal organs of the body.


The parts of the musculoskeletal system are as follows:

  • Bones : they are joined by means of joints, tissues and fibers allowing the movement of the body to take place. In total there are 206 bones in the human body and they provide protection to the body’s organs.
  • Joints : they form the connection between two bones giving movement and stability.
  • Cartilage : forms strong and flexible structures .
  • Muscles : made up of tendons and muscles attached to the bones.
  • Nervous system : creates the coordination and stimulation of the muscles to produce movement.


The locomotor system is found throughout the entire human body . Being made up of bones , muscles and joints , it is located in every corner of our body, including the head.

What are the systems that make up the locomotor system

The locomotor system is made up of the bone , nervous and muscular systems . The bone system is made up of the skeleton , which is made up of bones, cartilage and joints; And the muscular system is made up of muscles that connect to the bones through tendons, producing movement each time they contract.

Finally, the nervous system is made up of a series of specialized cells or neurons and it has a series of different nerves that perform different functions.

How does it work

Bones are attached to muscles and it is these that allow movement , both voluntary and involuntary. The muscles are then responsible for the bones to move. Locomotion depends on the bones , joints and muscles that function in a coordinated way stimulated by the nervous system .

The movement of the bones is produced by links that occur between the nerves and the muscles and the joints produce synovial fluid that reduces the friction between the bones producing less wear.

How it relates to the whole body

The locomotor system is related to other systems of the human body. Tightly linked with the bones , muscles , joints and ligaments , together they associate to enable us to move. Without this relationship, we would not be able to go from one place to another as the bones would be rigid and immobile .


Among the most common diseases that can affect the musculoskeletal system causing pain , disability and some deformities are: osteoarthritis, low back and neck pain, rheumatism, fibromyalgia, rheumatoid arthritis, spondylitis, some autoimmune diseases such as systemic lupus erythematosus and polymyalgia rheumatica.

Locomotor system care

It is very important to take care of and protect the locomotor system and for this we must:

  • Try to adopt the correct posture when sitting, walking or standing.
  • Maintain an upright, straight posture without excessive forward or backward lean.
  • You should try to eat foods that are rich in vitamins D and calcium .
  • Play sports .
  • When doing any type of sport, it is important to warm up before physical activities that require strength to avoid injuries .
  • Performing stretching after any activity physics .
  • Drink plenty of fluids .


The locomotor system is very important for the human body because it is in charge of shaping , moving and supporting the body. It provides protection to the internal organs of our body, supports weight and is an important source for the absorption of calcium and phosphorus . Thanks to the joints and muscle fibers, movement is possible, and all systems are interconnected, so without the musculoskeletal system, the body would be unable to function.
