• Axon

• Neurotransmitters

• Somatic Nerves

• Autonomic Nerves

Neurotransmitters are ______________ that travel across the ______________ to another cell.

• electrical signals; receptors

• electrical signals; synapse

• chemicals; receptors

• chemicals; synapse

What is number 3 pointing at on the neuron?

• Dendrite

• Axon

• Myelin Sheath

• Soma

Which part of the brain is also called the ' little brain'?

• Mid brain

• Cerebrum

• Cerebellum

• Fore brain

The fatty substance wrapped around the axon of a neuron that helps in fast and efficient conduction of impulses:

• Dendrite

• Synapse

• Myelin sheath

• cell body

Which lobe of the brain is concerned with vision?

• Frontal lobe

• Parietal lobe

• Temporal lobe

• Occipital lobe

The Central Nervous system consists of :

• Brain and spinal cord

• Brain and Peripheral nervous system

• Peripheral nervous system and autonomic nervous system

• All of the above

The right and left halves of the brain are connected by a bridge known as the :

• neuron

• glial cell

• corpus callosum

• temporal lobe

Threshold stimulus means that

• the size of the action potential does not change
• only one impulse is conducted at a time
• a certain level of stimulus is required to generate an action potential
• the membrane becomes repolarised quickly after an action potential passes

The time following an action potential in which no new action potential can be generated is called

• the refractory period
• the nerve impulse
• the stationary phase
• the threshold period
