reflexes

What two organ systems do large multicellular organisms like humans rely on for communication?

• Nervous system and endocrine system
• Respiratory system and digestive system
• Circulatory system and muscular system
• Skeletal system and integumentary system

What is the primary function of a neuron?

• To store nutrients
• To carry electrical impulses
• To absorb oxygen
• To produce hormones

What is a synapse?

• A hormone producing gland
• A type of muscle tissue
• A part of the brain
• The connection between two nerve cells

What part of the nervous system is responsible for processing sensory information?

• Central nervous system
• Somatic nervous system
• Peripheral nervous system
• Autonomic nervous system

What type of neuron carries information from receptors to the central nervous system?

• Interneurons
• Motor neurons
• Sensory neurons
• Relay neurons

Which type of neuron sends impulses to effectors?

• Motor neurons
• Relay neurons
• Glial cells
• Sensory neurons

What is a reflex arc?

• A nerve pathway for unconscious reflexes
• A type of brain wave
• A glandular response
• A muscle movement

Which component of the reflex arc takes the impulse from the spinal cord to an effector?

• Relay neuron
• Sensory neuron
• Receptor cell
• Motor neuron

What happens at the synapse when an electrical impulse reaches the end of a neuron?

• The impulse is amplified
• The neuron stops functioning
• Chemicals are released to transmit the signal
• The nerve cell divides

Which type of stimuli can sensory neurons detect?

• Muscle contraction strength
• Chemical composition of blood
• Changes in temperature
• Brain wave patterns
