  • Which neuroglial cell is found in the peripheral nervous system?
    Schwann cells are the neuroglial cells found in the peripheral nervous system.
  • Where do the cervical spinal nerves originate?
    Cervical spinal nerves originate from the cervical region of the spinal cord.
  • What is the somatic nervous system?
    The somatic nervous system is a part of the peripheral nervous system responsible for voluntary control of body movements via skeletal muscles.
  • What is the role of the somatic nervous system?
    The role of the somatic nervous system is to control voluntary movements and relay sensory information to the central nervous system.
  • What does the somatic nervous system control?
    The somatic nervous system controls voluntary movements of skeletal muscles.
  • Which nerve does not arise from the brachial plexus?
    C) Sciatic nerve
  • What does the somatic nervous system do?
    The somatic nervous system facilitates voluntary control of body movements and transmits sensory information to the CNS.
  • What instruction would you give to a patient when assessing their trigeminal nerve?
    Instruct the patient to clench their teeth and test facial sensation to assess the trigeminal nerve.
  • Which term describes a bundle of axons in the peripheral nervous system?
    A bundle of axons in the peripheral nervous system is called a nerve.
  • What types of functions can cranial nerves have?
    C) Cranial nerves can be sensory, motor, or both
  • Which cranial nerve is not a motor nerve?
    D) Optic nerve
  • Which division of the nervous system consists of all the nerves of the body?
    The peripheral nervous system consists of all the nerves of the body.
  • Which cell type is found only in the peripheral nervous system (PNS)?
    C) Schwann cells
  • Which division of the human nervous system carries signals to skeletal muscles?
    The somatic nervous system carries signals to skeletal muscles.
  • What are parts of the vertebrate peripheral nervous system?
    B) Sensory receptors and motor endings
  • In the peripheral nervous system, what is the function of afferent nerves?
    Afferent nerves in the peripheral nervous system facilitate the arrival of signals to the central nervous system.
  • What role does the somatic nervous system play?
    The somatic nervous system plays a role in voluntary control of body movements and sensory information processing.
  • What is the peripheral nervous system?
    The peripheral nervous system includes all neural structures outside the CNS, responsible for transmitting information to and from the CNS.
  • What is found in the ganglia of spinal nerves?
    Ganglia of spinal nerves contain clusters of neuron cell bodies.
