Question

How do the following systems work together and how do they differ - skeletal, muscle and nervous? Give three differences and two ways they work together each.

Answer 1

Skeltal system

1. It is the framework for body
2. There are 206 bomes in this system
3. Joints are present
4. They protect internal organs for example ribs protect lungs

Muscular system

1. They will not form framework but only attach to bones
2. Helps in strength of body
3. Contraction occur when force is applied
4. Voluntary and involuntary muscle are there but all skeltal bones are voluntary

Nervous system

1. It has brain and spinal cord
2. It cannot heal if wounded
3. Cannot regenerate
4. Made up of neurons
5. Receive message and respond

Similarities

1. The muscle attaches to skeltal system that is controlled by nervous system. This allows for movement for example we are able to walk ,run all because of coordination of these systems
2. Reflex arc - in this the nervous system is stimulated causing the contraction of muscle and the skeltal bones with muscle move according to reflex
