McConnell G11 nervous system quizz

The type of neuron which transports impulses TOWARDS the CNS

• A clever neuron

• Sensory neuron

• Interneuron

• Motor neuron

What is the part of the neuron which transports impulses away from the cell body

What is the function of the myelin sheath?

• Slows down the speed at which the impulse travels

• Increases the speed at which the impulse travels

• Directs the impulse away from the cell body

• Makes the neuron look pretty

The part of the neuron which directs the impulse towards the cell body

• Dendrite

• Axon

• Cell body

• Synapse

The order of neurons along which an impulse travels is

• Inter, Motor, Sensory

• Motor, Inter, Sensory

• Sensory, Inter, Motor

• There is no order

The nature of an nervous impulse is

• Slow

• Electrical

• Chemical

• Muscular

A synapse is

• A small gap between neurons

• An electrical impulse

• A gap between an interneuron and a sensory neuron ONLY

• Where the electrical impulse speeds up

A chemical which is released from a vesicle into the synaptic gap

• Electrical signal

• Neurotransmitter

• Glucose

• Microtransmitter

Why are there so many mitochondria present in the pre synaptic cell?

The myelin sheath is made up of

• Synapses

• Neurons

• Dendrites

• Schwann cells
