How do upper and lower motor neurons differ?
List and describe the basic steps involved in producing movement, beginning with the upper motor neurons in the cerebral cortex.
The lower motor neurons that innervate contractile skeletal muscle fibers are called:
a. α-motor neurons.
b. β-motor neurons.
c. upper motor neurons.
d. γ-motor neurons.
Which of the following is the correct order of events of a reflex arc?
a. Stimulus detection and delivery → motor response → integration in the CNS
b. Motor response → stimulus detection and delivery → integration in the CNS
c. Stimulus detection and delivery → integration in the CNS → delivery of motor response
d. Integration in the CNS → motor response → stimulus detection and delivery
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.
Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
b. The Golgi tendon organs detect stretch in a simple stretch reflex.
