FAQs on Reflex Action & Reflex Arc Video Lecture - Biology Class 11 - NEET
| 1. What is a reflex action? |  |
Ans. A reflex action is an involuntary and automatic response to a stimulus, which occurs without conscious thought or decision-making. It is a rapid, predictable, and unlearned response that helps protect the body from potential harm.
| 2. What is a reflex arc? | |
Ans. A reflex arc is the pathway that carries sensory information from a sensory receptor to the central nervous system (CNS) and then carries motor commands from the CNS to an effector organ or muscle. It involves a series of interconnected neurons that allow for the quick transmission and processing of sensory signals.
| 3. How does a reflex arc work? | |
Ans. A reflex arc works by following a specific sequence of events. When a stimulus is detected by a sensory receptor, such as touching a hot object, sensory neurons transmit the information to the spinal cord. In the spinal cord, the sensory neurons connect with interneurons, which process the information and send an immediate motor command through motor neurons. The motor neurons then activate the appropriate effector organ or muscle, causing the reflexive response.
| 4. What are some examples of reflex actions? | |
Ans. Some examples of reflex actions include the knee-jerk reflex, where tapping the patellar tendon causes a quick contraction of the quadriceps muscle, and the withdrawal reflex, where touching something painful, such as a hot surface, causes an immediate withdrawal of the affected body part. Other examples include the blink reflex, cough reflex, and gag reflex.
| 5. Can reflex actions be controlled or modified? | |
Ans. Reflex actions are typically automatic and cannot be consciously controlled. However, certain reflexes can be modified or suppressed under certain conditions. For example, with practice and training, a person can learn to suppress the blink reflex temporarily. Additionally, reflexes can be influenced by higher brain centers, such as when a reflex action is inhibited or modified due to a conscious decision or response to a specific situation.
