Which joint type is characterized by the articulating bones being separated by a fluid-filled joint cavity?

• Synovial Joint

• Gliding Joint

• Condyloid Joint

• Pivot Joint

What is the primary function of the Central Nervous System (CNS)?

• To pump blood throughout the body

• To process and integrate sensory information and coordinate motor responses

• To transport blood between the heart and the lungs

• To allow gas exchange in the lungs

Which system consists of nerves outside the CNS that connect to the rest of the body?

• Cardiovascular System

• Respiratory System

• Peripheral Nervous System (PNS)

• Muscular System

What is the role of neurotransmitters in the nervous system?

• To contract and relax muscles

• To pump blood

• To release chemical substances that transmit signals across synapses

• To transport oxygen

What does an action potential enable within a neuron?

• Muscle contraction

• Blood flow

• Electrical signal propagation along the axon

• Oxygen diffusion

Which organ is primarily responsible for pumping blood throughout the body?

• Lungs

• Diaphragm

• Heart

• Brain

What is the function of alveoli in the respiratory system?

• To pump blood

• To facilitate muscle contraction

• To allow gas exchange by letting oxygen diffuse into the bloodstream

• To transport blood
