Sensitivity and Coordination

  1. 1. Sensitivity andCoordination By Paula Crespo González
  2. 2.  A stimulus is anything that affects any of the body’s activities. There are two types of stimuli:  Internal  External A response is the body’s answer to a stimulus.
  3. 3.  The body has different receptors to receive different types of stimuli: ▪ Internal Receptors ▪ External Receptors
  4. 4.  The body responds to any stimulus ▪ Muscular responses ▪ Glandular responses
  5. 5.  The organ of the sense is the eye. The main part of the eye is the eyeball. Parts of the eye: Cornea, Pupil, Iris, Lens, Retina and the Optic Nerve.
  6. 6.  The ear is the body’s organ for the sense of hearning. The ear has three parts: ▪ The Outer Ear: It is made up of the ear and outer auditory canal. ▪ The Middle Ear: It is made up of the eardrum and a chain of small bones. ▪ The Inner Ear: It is made up of the cochlea and the auditory nerve.
  7. 7.  The body’s for the sense of touch is the skin  Epidermis: It is the outer layer.  Dermis: It is under the epidermis.  Hypodermis: It is under the dermis.
  8. 8.  The body’s organ of the smell is the nose. The receptor of smell are in the pituitary, a structure inside the nostrils.
  9. 9.  The body’s organ for the sense of taste is the tongue. The receptors of smell are in the taste buds.
  10. 10.  Brain: It is inside the skull. Spinal Cord: It is a thick cord made up of many neurons that goes through the inside of the spine.
  11. 11.  Sensory nerves: They transmit information from the sensory organs and internal organs to the central nervous system. Motor nerves: They transmit responses from the central nervous system to the muscles and glands of our bodies.
  12. 12.  Neurons are the cell that belong to the nervous system. They have a star-like shape made up of three parts: a cell body, dentrites and axons.
