What is the Reflex that causes reciprocal activation of antagonist muscle?

- Golgi tendon reflex
- When there is too much tension on a muscle, the afferent sensory nerves send the information to the spinal cord which sends its information to the cerebellum where the information is used to adjust muscle tension. Simultaneously, the motor neurons of the spinal cord that innervates the contracting muscle are inhibited and the antagonistic muscles are activated.
I believe (but am not certain sure) the term you're looking for is "deep tendon reflex" (aka "monosynaptic reflex").
When a muscle's tendon is suddenly stretched, receptors within the tendon send signals to cause the muscle contract, so it opposes the stretch.
This is the reflex that's tested when you tap just below your knee and your foot swings out (a knee-jerk reaction :-)

What is a flexor reflex?
Flexor reflex occurs when powerful stimuli (most often pain) causes the whole limb to be withdrawn from the site of stimuli. Reciprocal inhibition is vital (this relaxes the antagonist muscles) allowing the joint to be flexed and hence remove itself from the painful stimulus.

Why is the knee jerk reflex exaggerated when clenching a book?
Clenching an unrelated muscle group whilst inducing a refllex causes activation of gamma motneurones which inervate intrafusal muscle fibers causing them to be more sensitive to strech. A hightened sensitivity this causes and increased reflex response.
In response to a muscle being overstretched a muscle spindle generates a somatic spinal reflex that ultimately causes what response?
Both contaction of the agonist muscle and relaxation of the antagonist muscle
The reflex that causes an infant to close its fist when the palm is touched is called the what reflex?
Grasp reflex
Does A Reflex causes a Stimulus?
Yes
What reflex causes muscles relaxation and lengthening in response to muscle tension?
The reflex of the Golgi tendon.
What agent causes no gag reflex and decreased eye movement and nausea and vomiting?
Botulism causes no gag reflex and decreased eye movement and nausea and vomiting.
What character or thing in a novel that causes trouble is called?
The antagonist
What causes the let down reflex?
OT - Oxytocin from the posterior pituitary causes milk ejection
If a bee sting on the right thigh causes a quick involuntary reaction of the right arm what kind of reflex occured?
If a bee sting on the right thigh causes a quick involuntary reaction of the right arm, this would be an example of an intersegmental reflex. This is an unconditioned reflex.
Why does jendrassik's manoeuvre alter the amplitude of the reflex response?
It increases the reflex, as the subject is distracted by performing the manoeuvre and is said to prevent conscious anticipation of the reflex. Generally it should cause an increase in the duration and the magnitude of the reflex.
