PNS Review

Put the Steps of A reflex Arc in order

• Body Detects a Stimulus

• The information is sent to the Brain

• The sensory Neuron carries the information to the spinal cord

• An Interneuron in the SPINAL CORD coordinates a response

• Motor Neuron carries the impulse to an Effector to remove the body from harm

The skeletal muscles are controlled by this part of the nervous system.

• Somatic Nervous system
• Autonomic Nervous system
• astrocytes
• glial cells

The smooth muscles and glands are controlled by this part of the nervous system that is not consciously controlled.

• Somatic Nervous system

• Autonomic Nervous system

• Peripheral Nervous System

• Sensory Neurons

What is the proper name for a nerve cell?

• oligodendrocytes
• ependymal cells
• neurons
• Schwann cells

Nerves throughout the body and not in the brain and spinal cord.

• Autonomic Nervous System
• Somatic Nervous system
• Peripheral Nervous System
• Central Nervous System

The part of the neuron that receives nerve impulses.

• axon
• dendrite
• cell body
• axon terminus

White matter has this insulating covering that increases the rate at which an impulse can be carried.

• Schwann Cell
• axon membrane
• Neurilemma
• Myelin Sheath

Gaps in the myelin sheath.

• nodes of Ranvier
• axon endings 
• synapse
• neurotransmitters

conduct impulses from body parts to the brain or spinal cord.

• motor neurons

• sensory neurons

• interneurons

• microglia

Conduct impulses from one part of the brain or spinal cord to another part of the brain or spinal cord.

• motor neurons
• sensory neurons
• interneurons
• microglia
