A&P Reflex Quiz

What is the stretch reflex?

• The stretch reflex is a type of mental relaxation technique

• The stretch reflex is a muscle contraction in response to stretching within the muscle.

• The stretch reflex is a type of dance move

• The stretch reflex is a type of yoga exercise

Which type of reflex involves the contraction of muscles on one side of the body and the relaxation of muscles on the other side?

• Crossed extensor reflex

• Symmetrical contraction reflex

• Bilateral extensor reflex

• Unilateral flexor reflex

What are neural pools and circuits in the context of reflexes?

• Neural pools are areas of the brain where thoughts are processed, while neural circuits are the wires that connect them.

• Neural pools are groups of interneurons within the central nervous system that work together to carry out a specific function, while neural circuits are the pathways that connect different neural pools. In the context of reflexes, these neural pools and circuits are responsible for coordinating the sensory input and motor output involved in reflex actions.

• Neural pools are groups of fish in the ocean, while neural circuits are the paths they swim in.

• Neural pools are swimming pools for neurons, while neural circuits are exercise routines for the brain.

What is the function of muscle spindles in the body?

• Muscle spindles are sensory receptors within the muscles that provide information about muscle length and stretch to the central nervous system, helping to regulate muscle contraction and maintain posture.

• Muscle spindles aid in vision

• Muscle spindles regulate body temperature

• Muscle spindles help in digestion

Which reflex causes the withdrawal of a body part from a painful stimulus?

• The withdrawal reflex

• The attraction reflex

• The relaxation reflex

• The expansion reflex

True or False: The stretch reflex is a monosynaptic reflex.

• True

• Not sure

• Partially true

• False

True or False: The crossed extensor reflex is a polysynaptic reflex.

• Not applicable

• False

• Partially true

• True

What is the role of interneurons in neural pools and circuits?

• Interneurons are responsible for generating motor responses

• Interneurons have no role in neural pools and circuits

• Interneurons only transmit signals to sensory neurons

• Interneurons act as connectors within neural pools and circuits, integrating and processing information from sensory neurons and transmitting signals to motor neurons.

What is the purpose of the flexor reflex?

• The purpose of the flexor reflex is to make the body more vulnerable to harm

• The purpose of the flexor reflex is to have no effect on the body's response to pain

• The purpose of the flexor reflex is to protect the body from harm by quickly withdrawing from a painful stimulus.

• The purpose of the flexor reflex is to cause the body to move towards a painful stimulus
