  1. 1The [blank_start]regulation[blank_end] of the internal conditions of a [blank_start]cell or organism[blank_end] to maintain [blank_start]optimum[blank_end] conditions for [blank_start]function[blank_end], in response to internal or external [blank_start]changes[blank_end].
    1. Aregulation
    2. Bcell or organism
    3. Coptimum
    4. Dchanges
    5. Efunction
  2. 2Controlled internal conditions include:
    - [blank_start]thermoregulation[blank_end]
    - [blank_start]osmoregulation[blank_end]
    - [blank_start]blood glucose concentration[blank_end]
    1. Athermoregulation
    2. Bosmoregulation
    3. Cblood glucose concentration
  3. 3Receptors:
    cells that [blank_start]detect changes[blank_end]
    may be in the [blank_start]nervous system[blank_end] or [blank_start]hormonal control centres[blank_end]
    1. Adetect changes
    2. Bnervous system
    3. Chormonal control centres
  4. 4Coordination centres:
    areas that [blank_start]receive and process information[blank_end] from receptors
    includes the [blank_start]brain[blank_end], [blank_start]spinal chord[blank_end] and [blank_start]pancreas[blank_end]
    1. Areceive and process information
    2. Bbrain
    3. Cspinal chord
    4. Dpancreas
  5. 5Effectors:
    [blank_start]muscles or glands[blank_end] that bring about response
    respond to received stimulus
    restore conditions to optimum through [blank_start]chemical or physical[blank_end] changes
    1. Amuscles or glands
    2. Bchemical or physical
  6. 6The nervous system carries impulses between [blank_start]1-120[blank_end] metres per second
    1. A1-120
  7. 7Stimulus

    |
    Receptor

    | ([blank_start]sensory neurones[blank_end])

    Coordinator ( [blank_start]Central Nervous System[blank_end] )

    | ([blank_start]motor neurones[blank_end])

    Effector
    ( [blank_start]muscles[blank_end] may contract
    [blank_start]glands[blank_end] may secrete chemicals )
    1. Asensory neurones
    2. BCentral Nervous System
    3. Cmotor neurones
    4. Dmuscles
    5. Eglands
  8. 8The [blank_start]receptor[blank_end] sends an impulse along a [blank_start]sensory neurone[blank_end], carrying information about a change in the environment to the coordinator ([blank_start]CNS[blank_end]). Once all incoming information has been processed, the coordinator sends an impulse along the [blank_start]motor neurones[blank_end], which stimulate the [blank_start]effectors[blank_end] needed in a particular circumstance.
    1. Areceptor
    2. Bsensory neurone
    3. CCNS
    4. Dmotor neurones
    5. Eeffectors
  9. 9Experiments to measure reaction times:
    - [blank_start]ruler drop test[blank_end] ( reaction to visual stimulus )
    - hand squeeze around circle ( [blank_start]reaction to physical stimulus[blank_end] )
    1. Aruler drop test
    2. Breaction to physical stimulus
