Question
Select all correct descriptions of the motor pathways within the somatic division of the peripheral nervous system.Multiple select question.Fibers are carried by most cranial and all spinal nerves.The neurotransmitter is acetylcholine.Two neurons carry messages.Control is always involuntary.Effectors are skeletal muscles.
Solution
The correct descriptions of the motor pathways within the somatic division of the peripheral nervous system are:
- Fibers are carried by most cranial and all spinal nerves.
- The neurotransmitter is acetylcholine.
- Effectors are skeletal muscles.
The statement "Two neurons carry messages" is incorrect because in the somatic nervous system, only one neuron is involved in carrying messages from the central nervous system to the effector organs.
The statement "Control is always involuntary" is also incorrect because control in the somatic nervous system is usually voluntary.
