5.5.2 Animal responses

• Sensory cells or organs that detect stimuli are called receptors
• Shivering in response to cold is an example of an animal response.


  True
• Reflexive responses are automatic and involuntary
• Reflexive responses occur rapidly without conscious thought.


  True
• Learned responses involve conscious processing and memory
• Which type of response is mediated by the nervous system?

  Reflexive response
• The nervous system is the primary mechanism for mediating animal responses
• A reflex arc involves conscious thought.

  False
• For learned responses, the neural pathway includes the brain
• What is the role of sensory receptors in animal responses?

  Detect stimulus
• A reflex arc involves the brain in its pathway.

  False
• Reflexive responses occur without conscious thought
• Hormones travel through the bloodstream to bind to specific receptors on target cells.


  True
• Which hormone regulates blood glucose levels?

  Insulin
• Hormonal responses are faster than nervous system responses.

  False
• Sensory cells that detect stimuli are called receptors
• Shivering in response to cold is an example of a reflexive response.


  True
• Reflexive responses are mediated by the nervous system.
• Match the type of response with its example:

  Reflexive Response ↔️ Sneezing

  Learned Response ↔️ Pavlovian conditioning
• Reflexive responses occur without conscious thought
• Reflexive responses occur without conscious thought
• Learned responses can be modified over time.

  True
• What do nerves transmit in the nervous system?

  Electrical signals
• Learned responses involve complex neural pathways in the brain.

  True
• Order the steps of a reflexive response:

  1️⃣ Stimulus

  2️⃣ Sensory Receptor

  3️⃣ Sensory Nerve

  4️⃣ Spinal Cord

  5️⃣ Motor Nerve

  6️⃣ Effector
• Hormones travel through the bloodstream
• Hormonal responses are faster than nervous system responses.

  False
• What is the role of insulin in the body?

  Regulates blood glucose levels
• What are animal responses defined as?

  Actions to environmental changes
• Which type of tissue carries out the response in an animal response mechanism?

  Effectors
• Match the type of animal response with its description:

  Reflexive Response ↔️ Automatic, involuntary

  Learned Response ↔️ Acquired through experience
• Which system mediates reflexive responses in animals?

  Nervous system
• What is required for a learned response to occur?

  Experience or training
• Match the characteristic with the correct type of animal response:

  Automatic, involuntary ↔️ Reflexive Response

  Acquired through experience ↔️ Learned Response
• Learned responses can be modified over time.

  True
• What converts stimuli into electrical signals in the nervous system?

  Sensory receptors
• What type of responses involve more complex neural pathways in the brain?

  Learned responses
• The nervous system mediates both reflexive and learned responses in animals.


  True
• Effectors in the nervous system are muscles or glands.
• What is the sequence of a reflex arc pathway?

  Stimulus → Receptor → Sensory Nerve → Spinal Cord → Motor Nerve → Effector
