Nervous System and Reflexes

Neurons that transmit impulses the the CNS are called

• neuoglia
• sensory
• efferent
• association

Which neurons act to connect a sensory neuron to a motor neuron? 

• interneuron
• afferent 
• efferent
• motor

Which of the following is the final part of a reflex arc?

• integration center
• effector
• receptor
• sensory neuron

The nerves in the PNS are myelinated by

• Schwann cells
• Oligodendrocytes
• ependymal
• astrocytes

Effectors may be all of the following EXCEPT:

• cardiac muscle
• glands
• smooth muscles
• sensory cells

Which neurons send the stimulus to the effector muscle?

• SPINAL
• MOVEMENT
• SENSORY
• MOTOR

Processes that carry nerve impulses away from the cell body are calles

• Dendrites
• Axons
• Synapses
• Myelin sheaths

Reflexes (such as the knee-jerk reflex) occur when impulses travel from the muscle to the ? and then back to the muscle

• Brain
• spinal cord
• Dendrite
• axon
