Human Nervous System Flashcards
Coordination centres
Recieve and process information from the receptors. Eg brain, spinal chord.
Receptors
Cells that detect change in the internal or external conditions
Effectors
Muscles or glands that bring about a response to the stimulus
Homeostasis
Maintaining optinum internal conditions in response to the internal and external enviorment
Examples pf homeostasis
Bosy temperature
Blood glucose concentration
Water content of the body
Actions which are under concience control
Stimulus - receptor sensory neurone - central nervous system - motor neurone effector - stimulus
Actions not under consience control
Stimulus - receptor, sensory neurone - relay neurone in spinal cord-motor neurone, effector- response
