Nervous System Review

The branch like structures are called?

• Dents
• Branches
• Dentines
• Dendrites

The long slender pole connecting the neuron to the axon terminal is?

• Axeum
• Axon
• Axen
• Axam

What is the central nervous system

• The centre of each nerve cell
• The nerves that control the main functions of the body, such as heart rate and blood pressure
• The brain and spinal cord
• The nerves that prepare the body for fight or flight response

The portion of the nervous system that is considered involuntary is the ?

• Central nervous system
• Sensory nervous system
• Autonomic nervous system
• Motor nervous system

Neurons that conduct nerve impulses from the central nervous system to the effectors are ?

• Motor neurons
• Efferent neurons
• Relay neurons
• Sensory neurons

Neurons that conduct nerve impulses from the receptors to the central nervous system are

• Motor neurones
• Efferent neurons
• Relay neurons
• Sensory neurons

Gaps between the myelin sheath along an axon are called

• Dendrites
• Schwann cells
• Terminal branches

This insulating material forms a layer, around the axon of a neuron.  It enables electrical signals to travel down the axon at higher speeds.

• neuron
• myelin sheath
• dendrite
• neurotransmitter

The tiny gap between neurons where nerve impulses are sent from one neuron to another.  It is where communication occurs between an axon and dendrite

• synapse
• axon terminal
• impulse
• myelin
