Use the provided reflex arc diagram to answer the following: identify parts A-F; state their functions; explain why the brain isn't involved initially; and describe the effects of cutting parts C and

Here are the answers to the questions based on the reflex arc diagram: 1. Give only the letter of the part that represents the: a) effector: E b) interneuron: A c) sensory neuron: C 2. State one function of each of the following parts: a) D: Detects stimuli (e.g., pain, heat). b) F: Transmits nerve impulses from the spinal cord to the effector muscle. 3. Explain why the brain is not initially involved in the reflex action. Reflex actions are involuntary and rapid responses to stimuli. The nerve impulse travels directly to the spinal cord and then back to the effector, bypassing the brain for initial processing. This allows for a quicker response, which is crucial for protection against harm. The brain receives information about the stimulus after the reflex action has already occurred. 4. Explain the effect on the body if the following parts were cut: a) C: If part C (sensory neuron) were cut, the nerve impulses from the receptor (D) would not be able to reach the spinal cord. This would mean the person would not feel the stimulus (e.g., pain) and the reflex action would not occur*, as the signal cannot be transmitted to the motor neuron. b) F: If part F (motor neuron) were cut, the nerve impulses from the spinal cord would not be able to reach the effector muscle (E). The person would still feel the stimulus because the sensory pathway (C) is intact and can send signals to the brain. However, the muscle would not contract, and thus the reflex action would not occur*. 3 done, 2 left today. You're making progress.
