The efferent division includes which two subdivisions

Somatic and autonomic

The stretch reflex is classified as:

Monosynaptic and ipsilateral

The somatic nervous system includes:

Single motor neurons connecting CNS to skeletal muscles

The outermost covering of a nerve is called the:

Epineurium

The afferent division of the PNS carries information:

Toward the CNS

The PNS includes which two main divisions?

Sensory (afferent) and motor (efferent

The parasympathetic division promotes:

Energy conservation and routine maintenance

A reflex is:

A rapid, automatic response to a stimulus

Which group of spinal nerves emerges from the neck region?

Cervical nerves

Which of the following is an advantage of a nerve plexus?

Damage to one spinal segment does not completely paralyze a muscle

Fascicles within a nerve are surrounded by:

Perineurium

What role does the PNS play in motor control?

It carries motor commands from the CNS to muscles and glands

The withdrawal (flexor) reflex is:

Polysynaptic and ipsilateral

Voluntary motor responses originate in which motor control level?

Projection level

The vagus nerve (CN X) contributes to:

Homeostatic control of thoracic and abdominal organs

The autonomic nervous system operates:

Largely without conscious control

Reflexes are an example of which level of motor control?

Segmental level

The crossed-extensor reflex is:

Polysynaptic and contralateral

Which best describes the efferent division?

Transmits motor commands from CNS to effectors
