Back 1

autonomic - stimulus

Front 2

2 types of reflexes arcs

Back 2

monosynaptic - polysynaptic

Front 3

Back 3

conscious thought

Front 4

some reflex arcs involve lower ____

Back 4

brain

Front 5

some reflex arcs are carried out by the ____ ____ without any ____ involvement

Back 5

spinal cord - brain

Front 6

the reflex arc has neutral pathways with what 5 components

Back 6

sensory - sensory neuron - cns integrator center - motor neuron - effector

Front 7

monosynaptic reflex is a chain of

Back 7

only 2 neuron involvement

Front 8

example of monosynaptic reflex

Back 8

quad muscle stretches when tendon is tapped - muscle spindles send impulse that the muscle is stretching - spinal cord - motor neuron carries an impulse back to the quad - quad muscles contract

Front 9

polysynaptic reflex requires ___ or more sets of neurons

Back 9

3

Front 10

the polysynaptic is a ____ reflex ( crossed extensor reflex)

Back 10

withdrawal

Front 11

example of polysynaptic

Back 11

pain receptors - spinal cord - association neuron - integration - motor neurons to flexor muscles for contraction - flexors contract - extensors extend (called the crossed extensor reflex to keep the body balanced)

Front 12

5 other examples of reflexes

Back 12

knee jerk reflex - ankle jerk reflex - photopupil reflex - accommodation reflex - convergence

Front 13

perceived by the brain as pain from an extremity or body region rather than visceral pain

Back 13
