BS 5.7
Senses and impulses
Slide 1 - Tekstslide
Sensing things
What happens over here?
Slide 2 - Tekstslide
Sensing things
You
see
and
smell
chocolate
Using
sense organs
Signal
(impulse)
through
nerves
to your
brain
Brain send impulse to arm muscle -> you grab the chocolate
Slide 3 - Tekstslide
Sensory cells
Sensory organs have
sensory cells
Which are connected to
nerves
When the sensory cells receive a
stimulus
they generate an
impulse
(kind of
electrical signal
)
Slide 4 - Tekstslide
How an impulse starts
1. Stimulus needs to be strong enough ->
threshold value
= the lowest intensity of stimulus that causes an impulse
2.
Impulse frequency
- a stimulus gets stronger, more impulse per second
Slide 5 - Tekstslide
Adequate stimuli
A stimulus that sensory cells are particularly sensitive to, a sensory cell has a low threshold value for this stimulus
Example: Sensory cells in your eyes respond to light
Light is the adequate stimulus
Slide 6 - Tekstslide
Slide 7 - Tekstslide
3 types of nerve cells
notes:
1. Sensory neurons: pass the impulses from the sense organs to the CNS
2. Motor neurons: pass impulses from the CNS to the muscle/glands
3. Interneurons: conduct impulses within the CNS
