What is the role of the dendrite in a neurone?

• Receives nerve impulses from other neurones or the external environment

• Carries impulses out of the cell body to other neurones

• Sends signals to muscle cells, gland cells, or other neurone dendrites

• Integrates signals and coordinates metabolic activities

Which part of the brain is responsible for body coordination?

• Cerebellum

• Medulla Oblongata

• Axon

• Myelin Sheath

What is the function of the myelin sheath in a neurone?

• Protects neurones from injury

• Receives nerve impulses from the relay neurone of the central nervous system

• Integrates signals and coordinates metabolic activities

• Sends signals to muscle cells, gland cells, or other neurone dendrites

Which part of the neurone sends signals to muscle cells, gland cells, or other neurone dendrites?

• Cell Body

• Synaptic Knob

• Axon

• Node of Ranvier

What is the function of the node of Ranvier in a neurone?

• Helps to accelerate the flow of nerve impulses by allowing the nerve impulses to jump from one node to the following node

• Receives nerve impulses from other neurones or the external environment

• Carries impulses out of the cell body to other neurones

• Integrates signals and coordinates metabolic activities

Which type of neurone receives nerve impulses from the relay neurone of the central nervous system and sends impulses to effectors such as muscles or glands?

• Axon

• Sensory Neurone

• Relay Neurone

• Motor Neurone

What is the function of the axon in a neurone?

• Receives nerve impulses from other neurones or the external environment

• Integrates signals and coordinates metabolic activities

• Sends signals to muscle cells, gland cells, or other neurone dendrites

• Carries impulses out of the cell body to other neurones

Which part of the neurone is an insulating membrane that coats the axon?

• Cell Body

• Myelin Sheath

• Dendrite

• Synaptic Knob

What is the function of the synaptic knob in a neurone?

• Sends signals to muscle cells, gland cells, or other neurone dendrites

• Carries impulses out of the cell body to other neurones

• Receives nerve impulses from other neurones or the external environment

• Integrates signals and coordinates metabolic activities

Which part of the neurone is a swelling at the end of the axon branch?

• Node of Ranvier

• Axon
