B6: Brain and Mind
- Responding to Environmental Changes
- Responding to a Stimulus
- STIMULUS: a change in the
environment of an organism
- animals respond to stimuli in
order to keep themselves in
favourable conditions, eg...
- moving to somewhere
warmer if they're too cold
- moving towards food
if they're hungry
- moving away from
danger to protect
themselves
- moving to somewhere
warmer if they're too cold
- not responding to a stimulus is
a super effective way to die - at
the end of the day stimuli are
there to keep organisms alive
- STIMULUS: a change in the
environment of an organism
- Receptors
- RECEPTOR: an
organ or cell able to
detect an external
stimulus and transmit
a signal to a sensory
nerve, par exemple...
- light receptor cells in
the retina of the eye
- sound receptors
in the ear
- position
receptors in
the inner ear
- chemical receptors in
the nose and tongue
- touch, pressure,
temperature and
pain receptors in
skin
- light receptor cells in
the retina of the eye
- receptors respond to a
stimulus and send an
impulse along
SENSORY NEURONS
to the CENTRAL
NERVOUS SYSTEM
- RECEPTOR: an
organ or cell able to
detect an external
stimulus and transmit
a signal to a sensory
nerve, par exemple...
- Simple Reflexes
- simple reflexes produce
rapid INVOLUNTARY
RESPONSES to a stimulus
- this gives an
animal the highest
chance of survival
- यथा...
- moving towards and finding food
- moving away and sheltering from predators
- moving towards and finding a mate
- pupil dilation
- babies sucking nipples when
said nipples are placed inside
said babies' mouths
- knee jerk reflex
- moving towards and finding food
- this gives an
animal the highest
chance of survival
- mostly used by
'simple' animals (eg.
amoeba blublublub)
- simple reflexes produce
rapid INVOLUNTARY
RESPONSES to a stimulus
- Effectors
- EFFECTOR: an
organ or cell that
acts in response
to a stimulus
- either glands
or muscles (in
multicellular
organisms)
- either glands
or muscles (in
multicellular
organisms)
- carry out the
body's response
to stimuli
- EFFECTOR: an
organ or cell that
acts in response
to a stimulus
- Responding to a Stimulus
- The Nervous System
- Conditioned Reflex Responses
- Complex Behaviour
