Questions: The sensory nervous system contains both PNS and CNS components. The somatic nervous system component of the motor nervous system conducts impulses from the CNS to skeletal muscles. The visceral sensory component of the sensory nervous system is under voluntary control. The motor nervous system contains both CNS and PNS components.

The answer is:

$\square$ The sensory nervous system contains both PNS and CNS components. The somatic nervous system component of the motor nervous system conducts impulses from the CNS to skeletal muscles. The visceral sensory component of the sensory nervous system is under voluntary control. $\square$ The motor nervous system contains both CNS and PNS components.

Explanation:

1. The sensory nervous system contains both PNS and CNS components.

   • This statement is true. The sensory nervous system includes sensory receptors and neurons in the peripheral nervous system (PNS) that transmit information to the central nervous system (CNS), where it is processed.

2. The somatic nervous system component of the motor nervous system conducts impulses from the CNS to skeletal muscles.

   • This statement is true. The somatic nervous system is responsible for voluntary movements and conducts motor impulses from the CNS to skeletal muscles.

3. The visceral sensory component of the sensory nervous system is under voluntary control.

   • This statement is false. The visceral sensory component is responsible for transmitting information from internal organs to the CNS and operates involuntarily.

4. The motor nervous system contains both CNS and PNS components.

   • This statement is true. The motor nervous system includes motor neurons in the CNS that send signals to the PNS to control muscles and glands.

Summary: The true statements are:

• The sensory nervous system contains both PNS and CNS components.
• The motor nervous system contains both CNS and PNS components.
