SYSTEM

The nervous system is made up of
nerve centres and nerves
NEURONS
• Both the central and the peripheral nervous
systems are made up of specialised cells called
neurons.

VOLUNTARY AND INVOLUNTARY
MOVEMENTS

Our bodies react to stimuli making voluntary or involuntary
movements
VOLUNTARY MOVEMENTS
• The brain produce a response in the case of
voluntary movements.
INVOLUNTARY MOVEMENTS
• The spinal cord produces a response in the
case of involuntary movements
THE SKELETAL AND THE MUSCULAR
SYSTEM
THE SKELETON
• The skeleton is made of the bones in the body
• Head bones: there are two groups, skull bones
and facial bo...
JOINTS
The joints are located where two or more bones
met.
There are two types of joints:
• Movable joints
• Semi-moveable...

It is the set of muscles in the body.

  14. 14. THE NERVOUS SYSTEM The nervous system is made up of nerve centres and nerves
  15. 15. NEURONS • Both the central and the peripheral nervous systems are made up of specialised cells called neurons. • They are made up of a cell body, dendrites and axons.

  20. 20. THE SKELETON • The skeleton is made of the bones in the body • Head bones: there are two groups, skull bones and facial bones. • Trunk bones: there are two groups , the spine and the rib cage. • Limb bones: there are two groups, upper limb bones and lower limb bones.
  21. 21. JOINTS The joints are located where two or more bones met. There are two types of joints: • Movable joints • Semi-moveable joints • Fixed joints
  22. 22. THE MUSCULATURE It is the set of muscles in the body. Head muscles : masseter, buccinator and orbicular. Trunk muscles : sternoclaidomastoid, abdominal and pectoral Limb muscles :biceps , triceps, deltoid, quadriceps, gluteus and calf muscles
