neurons

Question 1

Sensory neurons

Answer 1

Receives and carries sensory information which is received from both our external and internal environments then transmitted to the CNS.

Question 2

Motor neurons

Answer 2

carry messages from the CNS to the cells in skeletal muscles, organs and glands to stimulate activity.
They enable muscles to move so we can walk or speak.

Question 3

Interneurons

Answer 3

Act as a link between sensory and motor neurons, relaying information from one to the other and are located in the spine

Question 4

Dendrites

Answer 4

They detect and receive neural information in a chemical form.

Question 5

Soma

Answer 5

The cell body, holds the nucleus, the structure that determines whether the neuron will be activated and thus transmit messages to other neurons

Question 6

Axon

Answer 6

Transmits messages in the form of an electrical impulse, from the soma to other cells in the body

Question 7

Myelin

Answer 7

A white fatty substance that encases the axon that helps speed up transmission called myelin sheath.

Question 8

Axon terminals

Answer 8

At the end of each axon are branches called axon terminals. They form a synapse with the next neuron. This is where neurotransmitters are released.

Question 9

Neurotransmitters

Answer 9

They are molecules used by the nervous system to transmit messages between neurons, or from neurons to muscles

Question 10

Synapse

Answer 10

A Synapse is a microscopic gap between neurons over which messages pass
