SAIES S.A.M.E |
|
Define intergrating center
|
point in which there is synaptic contact between neuron and gray matter of spine or brain
|
|
In flexor reflex what contracts and what relaxes? What is the medical term?
|
Contract flexors, relax extensors (reciprocal inhibitation)
|
|
flexor reflex is polysynaptic or monosynaptic?
|
Polysynaptic reflex arc due to complex movements
|
|
Reflex on same side of spinal cord?

Where do reflex signals travel?
|
REFLEX ARC

|
|
WHAT pathway does crossed extensor reflex use?
|
Contralateral reflex arc
|
|
What is crossed extensor reflex mediated by??
|
cerebellum and/or cortex
|
|
What is involved in tendon reflex
|
collagen fibers and tangled nerves
|
|
How does tendon reflex happen
|
muscle contracts, collagen fibers constrict and put pressure on nerve, nerve provides CNS information on tension at joint

|
What is intersegmental reflexive arc??
|
input and output all over spinal cord
