B10-Nervous system
explain how the structures of the
reflex arc
are related to their function
sensory neurone
synapse
relay neurone
motor neurone
homeostasis
definition
why is homeostasis needed?
what conditions do we need to maintain?
automatic control systems may involve nervous responses or chemical responses
receptors
coordination centres (such as the brain, spinal cord and pancreas)
effectors (muscles or glands)
The nervous system enables humans to react to their surroundings and to coordinate their behaviour
what is a coordinated response?
what is a reflex and why are they important?
Required practical activity 6:
plan and carry out an investigation into the effect of a factor on human
reaction time
method (write out in steps)
how do you gain
valid
results?
explain how the structure of the nervous
system is adapted to its functions
draw out the steps of a nervous response
how do stimulants affect reaction times?
