Textbook Question
Chapter 13, Problem 17CYR
Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
a. The simple stretch reflex is a monosynaptic reflex with only a single synapse in the spinal cord between the sensory and motor neurons.
b. The Golgi tendon organs detect stretch in a simple stretch reflex.
c. A flexion reflex is a monosynaptic reflex with only one synapse in the spinal cord.
d. The crossed-extension reflex occurs simultaneously with the simple stretch reflex.

Which of the following is NOT a reason why a reflex arc is faster than a normal nerve transmission?
a. A reflex arc stimulates the motor neurons for an immediate reaction.
b. A reflex arc does not send information to the brain to be processed.
c. A reflex arc does not involve neurotransmitters.
d. A reflex arc involves fewer neurons.
In the knee-jerk reflex, the afferent neurons
Select one:
a. innervate leg flexor muscles
b. are sensory neurons
c. innervate leg flexor and extensor muscles
d. innervate leg extensor muscles
e. are cranial nerves
In the stretch reflex,a. Golgi tendon organs activate contraction in extrafusal muscle fibersconnected to that tendon.b. lengthening of muscle-spindle receptors in a muscle leads tocontraction in an antagonist muscle.c. action potentials from muscle-spindle receptors in a muscle formmonosynaptic excitatory synapses on motor neurons to extrafusal fiberswithin the same muscles.d. slackening of intrafusal fibers within a muscle activates gamma motorneurons that form excitatory synapses with extrafusal fibers within thatsame muscle.e. afferent neurons to the sensorimotor cortex stimulate the agonist muscle to contract and the antagonist muscle to be inhibited
