So the next reflex is the tendon reflex.
This causes relaxation of a muscle
that is attached to a stimulated tendon.
This usually controls muscle tension and is different
from the stretch reflex which controlled muscle length.
An example of a tendon reflex would be if
someone were to throw a heavy bowling ball to you.
Because that tension is so
strong and that force is so strong,
your reflex will cause you to drop
the bowling ball or relax your muscles
instead of trying to take on that tension.
So in this example when the
bowling ball is thrown to you,
that increased tension is going to stimulate
the sensory receptors in the tendon organ
From there, the sensory neuron is going to
propagate a nerve impulse to the spinal cord.
In this portion, an interneuron
is going to then send a signal
to both the antagonistic
and the agonistic muscle
So in the integrating center, we're actually
going to activate inhibitory interneurons.
This inhibitory interneuron is going to
send a message to the motor neuron
which is going to inhibit and
cause relaxation of that muscle.
Opposite to this in the antagonistic muscle
we are going to send an activating signal
which is going to cause
contraction of that muscle.
So once we get to the effector, the
muscle that is attached to the tendon
that received that stimulus is going to relax
and the antagonist muscle is going to contract
This will cause you to drop the bowling ball or
in this situation to move your foot backwards.
