Sensitivity and Coordination by José Carlos

  1. 1. The function of sensitivity is to produce a response to a stimulus we receive. Stimuli A stimulus is anything you see , hear , touch, smell or taste. Stimuli can be internal or external: Internal stimuli. External stimuli.
  2. 2. The body has diferent receptors to receive diferents types of stimuli. There are two types of receptors: Internal receptors. External receptors.
  3. 3. A response is the body´s answer to a stimulus . Muscular responses. Glands responses.
  4. 4. Thesenses
  5. 5. The eye is the organ of sight. It is made up of the eyeball and protectedby the eyebrows , eyelids and eyelashes.
  6. 6. The nose is the organ of smell.The receptors of smell are in the pituitarygland , inside the nostrils.
  7. 7. The ear is the organ of hearing. It has tree parts: The outer ear includes the ear and the ear canal. The middle ear includes the eardrum and the small bones. The inner ear includes the cochlea and the auditory nerve.
  8. 8. The skin is the organ of touch.It is made up of tree layers:Epidermis , dermis and hypodermis
  9. 9. The tongue is the organ of taste.The receptors of taste are in the taste buds
  10. 10. The nervous sytem is made up of nerve centres and nerve The central nervous system has two parts: The brain inside the skull. It is made up of cerebrum , cerebellum and the brain stem. The spinal cord is made up of many neurons it is protected by vertebrae. The peripheral nervous system is made up of : Sensory nerves. Motor nerves.
  11. 11. They are made up of a cell body , dendrites ,axons.Neurons receive information from otherneurons .
  12. 12. 1. When we see the clouds our sensory nerves inform the brain about this.2. Our brain processes the information and produces a response , deciding to look for an umbrella.3. Our motor nerves transmit a responses to the muscles , making them move to take the umbrella and open it.
  13. 13. The spinal cord produces a resposes in the case of involuntary movements. Sensory nerves: transmit information about involuntary movements to the spinal cord. The spinal cord: produces a very fast response and transmits it to the muscles through the motor nerves.
  14. 14. The skeletal and musculature system is incharge of carrying muscular responsescreated by the nervous system.It is made up of the skeleton andmusculature.
  15. 15. The skeleton is made up of all 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 rig cage. Limb bones.There are two groups , the upper limb bones and the lower limb bones.
  16. 16. The joints are located where two or more bones meet.Bones are connected by resistant fibres called ligaments There are tree types of joints: Moveable joints Semi-moveable joints Fixed joints
  17. 17. The musculature is the set of muscles in the body. Locomotor muscles are connected to the bones . Head muscles:masseter , buccinator , orbicular. Trunk muscles:sternocleidomastoid , abdominal , pectoral ,intercostal , trapezius. Limb muscles:biceps, triceps , deltoid , quadriceps , gluteus , calf muscles.
