    brain, spinal cord, nerves
  • name 2 parts of the central nervous system
    brain, and spinal cord
  • what is the function of the central nervous system
    receives information from the senses, and make an appropriate response
  • name the part of the brain responsible for conscious thought and memory
    cerebrum
  • what is the function of the cerebellum
    muscle coordination and balance
  • what part of the brain controls the heart and breathing rate?
    medulla
  • name the structures which detect a sensory input
    receptors
  • name the specialised cell which carries an electrical impulse to the central nervous system
    sensory neuron
  • name the specialised cell linking sensory and motor neuron, operate within the CNS, and processes information from the senses that require a response
    inter neuron
  • a motor neuron carries an impulse from the CNS to an effector. give 2 examples of an effector
    muscle, gland
  • what is the function of a reflex?
    to protect the body from harm
  • name the junction where chemicals transfer the message between neurons
    synapse
  • what is a hormone?
    they are chemical messengers that travels in the blood
  • what kind of gland releases hormones into the bloodstream
    endocrine gland
  • why are only some tissues affected by specific hormones
    cells will only be affected by a hormone if they have the complementary receptor protein for that specific hormone
  • name the endocrine gland that monitors blood glucose levels and make hormones for the regulation of glucose
    pancreas
  • name the condition caused by a communication pathway that has failed due to a fault or failure to respond to insulin
    diabetes
  • what function does insulin have in the body
    it causes liver cells to store glucose as glycogen, and brings blood glucose levels back down
  • which hormone breaks down glycogen in the liver to glucose
    glucagon
