Biology: Transmission of Nerve Impulses

Receptors trigger the nerve impulses in the _____________

• Spinal Cord

• Muscles

• Afferent neurones

• Efferent neurones

What is the function of the brain in the process of transmission?

• Receives impulses from receptors

• Receives impulses from muscles

• Interprets nerve impulses from efferent neurones

• Interprets nerve impulses from interneurones

A nerve impulse is conducted along the ______ of a neurone until it reaches the synaptic ________.

• branch...transmitter

• receptor...transmitter

• axon...terminal

• receptor... cleft

What is the narrow space beyond the synaptic terminal known as?

• Neurotransmitter cavity

• Axonic space

• Synaptic cleft

• Synaptic vesicles

The transmission of nerve impulses across the synaptic cleft needs _________.

• Neurones

• Neurotransitters

• Neurone Expressers

• Neurotransmitters

Where are the neurotransmitters stored?

• Synaptic muscle

• Receptors

• Effectors

• Synaptic vesicles

The synaptic terminal contains abundant ____________ to transmit nerve impulses continuously.

• Nucleus

• Cytoplasm

• Iron

• Mitochondria

Neurotransmitters are _________.

• Rapidly broken down by enzymes

• Taken up again by the synaptic terminal

• Formed at the tip of the toes.

• Only found in the tongue and skin.

When an electrical impulse reaches the presynaptic membrane, _________.

• It triggers the synaptic vesicles to release neurotransmitters into the synaptic cleft.

• Axons will be destroyed and reformed.

• Neurones around the particular conducting neurone will rotate.

• Neurotransmitters will be formed and will fill the the spaces between neurones.

The neurotransmitters diffuse across the synaptic cleft and bind to specific ________ or _________.

• fibres...sensory organs

• proteins...receptors

• muscles...sensory organs

• proteins...sensory organs
