Sensitivity and Coordination by José Carlos Sensitivity and Coordination by José Carlos Presentation Transcript

  • 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.
  • The body has diferent receptors to receive diferents types of stimuli. There are two types of receptors: Internal receptors. External receptors.
  • A response is the body´s answer to a stimulus . Muscular responses. Glands responses.
  • Thesenses
  • The eye is the organ of sight. It is made up of the eyeball and protectedby the eyebrows , eyelids and eyelashes.
  • The nose is the organ of smell.The receptors of smell are in the pituitarygland , inside the nostrils.
  • 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.
  • The skin is the organ of touch.It is made up of tree layers:Epidermis , dermis and hypodermis
  • The tongue is the organ of taste.The receptors of taste are in the taste buds
  • 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.
  • They are made up of a cell body , dendrites ,axons.Neurons receive information from otherneurons .
  • 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.
  • 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.
  • The skeletal and musculature system is incharge of carrying muscular responsescreated by the nervous system.It is made up of the skeleton andmusculature.
  • 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.
  • 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
  • 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.
