  2. 2. INDEX 1. Stimulus and response 2. The senses 2.1. Sight 2.2. Smell 2.3. Hearing 2.4. Touch 2.5. Taste 3. The nervous system 4. Type of movements 5. The skeletal system 6. The muscular system
  3. 3. 1. STIMULUS AND RESPONSE  A stimulus is anything you see, hear, touch smell or taste. There are two types:  Internal stimuli  External stimuli  The body has two receptors:  Internal receptors  External receptors  A response is the body´s answer to a stimulus. There are two types:  Muscular responses  Glandular responses
  4. 4.  2. THE SENSES
  5. 5. 2. THE SENSES 2.1. Sight The eye is the organ of sight
  6. 6. 2. THE SENSES 2.2. Smell The nose is the organ of smell
  7. 7. 2. THE SENSES 2.3. Hearing The ear is the organ of hearing
  8. 8. 2. THE SENSES 2.4. Touch The skin is the organ of touch
  9. 9. 2. THE SENSES 2.5. Taste The tongue is the organ of taste
  10. 10. 3. THE NERVOUS SYSTEM  The nervous system is made up of nerve centres and nerves  The central nervous system is formed by nerve centres that interpret the information and develop responses. It has two parts:  Brain  Spinal cord  The peripheral nervous system is made up by nerves that transmite information. It is made up of:  Sensory nerves  Motor nerves
  11. 11. 4. T YPE OF MOVEMENTS  Voluntary movements: the brain produces a response  Involuntary movements: the spinal cord produces a response. The sensory nerves transmit information about involuntary movements to the spinal cord; and it produces a very fast response and transmits it to the muscles
  12. 12. 5. THE SKELETAL SYSTEM  The skeleton is made up of all the bones in the body:  Head bones: skull bones and facial bones  Trunk bones: spine and ribe cage  Limb bones: upper limb bones and lower limb bones
  13. 13.   The musculature is the set of muscles in the body: Head muscles: masseter, buccinatur and orbicular Trunk muscles: sternocleidomastoid, abdominal, pectoral, intercostal, trapezius and dorsal Limb muscles: biceps, triceps, deltoid in the upper limbs; and quadriceps, gluteus, tibial and calf muscles in the lower limbs   6. THE MUSCULAR SYSTEM
