Membrane Transport

A polarized neuron is said to be in –

• Action potential

• Spike potential

• Resting potential

• None of these

When a neuron is not conducting any impulse i.e. resting, the axonal membrane is –

• Comparatively more permeable to K⁺ and impermeable (nearly impermeable) to Na⁺

• More permeable to Na+ ions than K+ ion.

Which is the correct order/sequence of the parts of a neuron in a neural impulse?

• axon, dendrite, cell body, synapse
• dendrite, axon, cell body, synapse
• synapse, axon, dendrite, cell body
• dendrite, cell body, axon, synapse

An axon conducts nerve impulses _________ the cell body.

• away from
• toward
• both toward and away
• around, bypassing

What is the purpose of the nervous system?

• Control and communication of and between systems of the body.

• To let you know when you when you should feel anxious about something.

Myelin would be which color of structure?

• the red one

• the blue one

• the green one

• the purple one

What do Dendrites do?

• Intakes information from other neurons

• Produces fatty tissue for the Myelin Sheath

• Sends information to the next cell

• Controls the speed of electrical signal through the axon

which is the correct path that a nerve impulse will follow in a reflex arc?

• motor neuron--> interneuron--> sensory neuron

• interneuron--> motor neuron --> sensory neuron

• motor neuron--> sensory neuron--> interneuron

• sensory neuron--> interneuron--> motor neuron

What do Axon Terminals do?

• Intakes information from other neurons

• Produces fatty tissue for the Myelin Sheath

• Sends information to the next cell

• Controls the speed of electrical signal through the axon

The Nervous System is divided into two parts called

• The Central Nervous System & The Peripheral Nervous System

• The Central Nervous System & The Paradigm Nervous System

• The Corollary Nervous System & The Paradigm Nervous System

• The Corollary Nervous System & The Peripheral Nervous System
