HBS 2.1.7 reflexes

What is the difference between reflexes and reactions?

• Reflexes are voluntary actions that require conscious thought, while reactions are automatic responses to stimuli.

• Reflexes are automatic responses to stimuli that do not require conscious thought, while reactions involve conscious effort and cognitive skill.

• Reflexes and reactions are the same and can be used interchangeably in psychology.

• Reflexes are slower than reactions and involve more cognitive processing.

Explain the term 'involuntary response'.

• An automatic reaction that occurs without conscious control, such as a reflex.

• A deliberate action taken after careful thought.

• A response that requires conscious effort and decision-making.

• A learned behavior that is practiced over time.

What is the role of sensory neurons in reflex actions?

• Sensory neurons transmit signals from sensory receptors to the spinal cord, initiating a reflex action.

• Sensory neurons are responsible for processing information in the brain.

• Sensory neurons help in the voluntary movement of muscles.

• Sensory neurons are involved in the production of hormones.

What is the spinal reflex arc?

• A neural pathway that mediates a reflex action, involving sensory neurons, interneurons, and motor neurons.

• A type of voluntary movement controlled by the brain.

• A complex network of blood vessels in the spinal cord.

• A mechanism for transmitting pain signals to the brain.

True or False: Sensory neurons send signals to the brain for the patellar reflex.

• True, sensory neurons send signals to the brain for the patellar reflex.

• False, sensory neurons send signals directly to the spinal cord.

• True, sensory neurons do not send signals for the patellar reflex.

• False, sensory neurons send signals to the heart for the patellar reflex.

Which develops first in children: good reflexes or fast reaction time?

• Good reflexes develop first.

• Fast reaction time develops first.

• Both develop at the same time.

• Good reflexes and fast reaction time are unrelated.

What factors can affect reaction time?

• Age

• Weather conditions

• Time of day

• Type of food consumed

What is the significance of reflex testing in medicine?

• It helps assess the integrity of the nervous system and can indicate neurological disorders.

• It is used to measure blood pressure and heart rate.

• It determines the level of physical fitness in patients.

• It is primarily used for diagnosing respiratory diseases.

How do reflexes differ from learned behaviors?

• Reflexes are voluntary actions, while learned behaviors are involuntary.

• Reflexes are innate and automatic, while learned behaviors are acquired through experience and practice.

• Reflexes require conscious thought, while learned behaviors do not.

• Reflexes are slower than learned behaviors.

Define 'reflex'.

• A reflex is a voluntary action taken in response to a stimulus.

• A reflex is an involuntary and nearly instantaneous movement in response to a stimulus.

• A reflex is a learned behavior that requires conscious thought.

• A reflex is a slow and deliberate response to a stimulus.
