  • What are the four basic elements involved in the Interaction Function?
    stimuli, receptors, coordination centers, and effectors
  • What is the function of Divergent Circuits?
    carries nerve impulses from one place to several organs
  • What two systems are Effectors?
    the endocrine system and the locomotor system
  • What makes up the central nervous system?
    the Brain and the Spinal Cord
  • What is this an example of: in cold weather, the nervous system and endocrine systems work together to keep the body's internal temperature at 37 degrees.
    Homeostasis
  • What is the function of Convergent Circuits?
    carries impulses from several places to one organ
  • What is an Axon?
    a long nerve fibre that carries electrical messages from the cell body and sends it to other cells
  • What are stimuli?
    any changes in the environment that are detected by an organism
  • What are the three groups that neurons can be put into?
    Sensory neurons, Motor neurons, and Interneurons
  • What is the function of Grey Matter?
    processes information in the brain
  • what are receptors?
    Located in the sense organs that detect stimuli and send information to the nervous system
  • what does the endocrine system do?
    produce hormones
  • What is homeostasis?
    the body's ability to maintain a stable internal environment when it detects changes in the external environment
  • What is Negative Feedback?
    A process that occurs when an organism reacts to stimuli by slowing down or stopping a process that's happening
  • What does the cell body contain?
    the nucleus and cytoplasmic organelles
  • White Matter and Grey Matter make up what 2 parts of the central nervous system?
    the brain and the spinal cord
  • what does the locomotor system produce?
    movement
  • What are Dendrites?
    short nerve fibers that carry information from other neurons to the cell body
  • True or False: the action of the Nervous System is long-lasting
    false, it is short-lasting
  • what are effectors?
    muscles and glands that receive the response and react to the stimuli
  • What 2 systems is the nervous system divided into?
    central nervous system and peripheral nervous system
  • What is the function of interneurons?
    carry information between motor and sensory neurons
  • What are coordination centers?
    Where the nervous system receives the information and sends a response to the effectors
  • What is the function of Sensory Neurons?
    carry information from the senses to the brain
  • What is the function of motor neurons?
    carry information from the brain to muscles or glands
  • What is the function of the cell body?
    The cell body receives information, it contains the nucleus and cytoplasmic organelles
  • What part of the neuron structure is a long nerve fibre that carries electrical messages from the cell body and sends it to other cells?
    Axon
  • What are reflexes?
    automatic actions that the body does in response to stimuli
  • When neurons connect to each other, what is it called?
    a circuit
  • What is another name for the cell body?
    Soma
