structure and role of neurons

Question 1

what is a neuron?

Answer 1

nerve cell - transmits electric and chemical signals/ messages in the body

Question 2

role of dendrite

Answer 2

• branches of a neuron that transmit electrical impulses toward the cell body
• role in communication between neurons, allowing the brain to process info and respond to stimuli.

Question 3

What is the role of the cell body of a neutron?

Answer 3

contains the nucleus and is responsible for maintaining cells functions and processes

Question 4

What is the role of the axon in a neuron?

Answer 4

carries electrical impulses away from the the cell body to other neurons, muscles or glands

Question 5

What is the myelin sheath and its function?

Answer 5

fatty layer that covers the axon - speeds up the transmission of electrical impulses and protects the axon

Question 6

What are the synapses and their function?

Answer 6

junctions between the neurons where electrical signals are transmitted chemically using neurotransmitters

Question 7

What are the role of neurotransmitters in neural communication?

Answer 7

neurotransmitters are chemicals that transmit signals across synapses from one neuron to another, influencing behaviour and bodily functions
