Science skeletal and muscular quiz

Adults have 206 bones and infants have around 300 bones.


What are the purposes of the skeletal system?

To provide support, allow movement, produces blood cells, stores minerals, protects our organs.

  1. What are ligaments, tendons and cartilage?

Ligaments connect your bones and they are like strong ropes/bands that hold joints together.

Tendons connect muscles to bones and they link the muscles to the skeleton and the

Cartilage is a tissue that sort of  cushions throughout the body it is a smooth tissue that allows for smooth movement.

  1. What are the different types of joints in the body and know an example for each.
    Gliding: allows slight gliding movements and one example is joints between the bones of the wrist and ankle.

    Pivot: Allows rotation and is a joint between the first two vertebrae in the neck.

    Hinge : Allows movement like a door hinge and is in the elbow and knee joints.

    Ball and socket. Allows movement in all directions and in the shoulder and hip joints.


    How do the muscular and skeletal systems work together?

They work together to allow movement.


  1. How do the muscular and skeletal systems work together?

  1. What are the different types of muscle tissue and where can they be found? Give examples of each.


A skeletal muscle - biceps

A cardiac muscle - heart

A smooth muscle- stomach


How do our muscles work?

They work by shortening and tightening.


What kind of muscle tissue has the most mitochondria and why?

The cardiac muscle has the most mitochondria because it is working constantly.


What is the difference between voluntary and involuntary muscle? Give an example of each

A voluntary muscle are under you conscious control and a example is your biceps.
