CIENCIAS 5º 14/05/20 Tarea 38 con Omar

Hola! Happy Thursday everyone 🙂 

Last week’s questions and answers (las preguntas y respuestas de la tarea de la semana pasada): 

Question 1: What is the difference between voluntary movement and reflex movement? 

Answer: Voluntary movements consist of movements we are aware of and decide to do. Reflex movements consist of movements that are involuntary and automatic. 

Health and the Locomotor System 

To keep our locomotor system healthy, we need to have good habits in our daily life. These include a healthy diet, exercise, and good posture. 

Injuries of the Locomotor System 

Some common injuries in the locomotor system are: 

  • Bone fractures. These happen when bones break or crack. 
  • Sprains. These involve damage to ligaments, usually caused by twisting. Sprains are most common in the ankles, knees, and wrists. 
  • Muscle strains. These are an involuntary and prolonged muscle contractions. They can be caused by bad posture or excessive effort. 

A Healthy Diet 

As we develop, our bones grow. Bone growth requires calcium and phosphorus. They are found in milk, dairy products, nuts, pulses, shellfish, and some vegetables. 

Calcium is a mineral that helps bones to harden. Vitamin D helps the body to absorb calcium. Not getting enough vitamin D can cause a disease called rickets. Sunlight is an important source of vitamin D. It is also found in some foods, like oily fish. 

Physical Activity 

We can keep the locomotor system in good shape by developing elasticity and strengthening our muscles. 

To prevent sports injuries, you should always warm up before playing sports and do stretching exercises afterwards. 

It is also important to have a good posture. For example, when you carry your school bag or when you sit at a table.
