Here is a diagram of a reflex action.What happens at F? A B F E D

Final answer: 'F' in context of a reflex arc most likely represents the effector, the muscle or gland that creates a reflex action, such as muscle contraction or hormone secretion. Explanation: Without a specific diagram provided, it's difficult to determine what 'F' refers to. However, in context, 'F' should be a point within a reflex arc, the neural pathway that controls reflex actions. A reflex arc occurs in the following order: stimulus, receptor, sensory neuron, integration center (usually spinal cord), motor neuron, and effector. 'F,' being the last letter, likely represents the effector - the muscle or gland that responds to the neural impulse, creating the reflex action. This could involve muscle contraction or the secretion of hormones. Learn more about Reflex Arc here: brainly.com/question/14473426 #SPJ12

Final answer: In a reflex action, F represents the effector, which carries out the response. Explanation: In a reflex action, the letter F represents the effector. The effector is the part of the reflex arc that actually carries out the response. It can be a muscle or a gland that responds to the information sent by sensory neurons. For example, if you touch a hot stove, the sensory neurons transmit the information to the spinal cord, and from there, the motor neurons signal the effector to move your hand away from the stove to prevent further injury. Interneuron (or Relay Neuron): In some reflex arcs, there is an interneuron located within the CNS. It receives the sensory input, processes the information, and communicates with the motor neuron. Motor Neuron: The motor neuron, also known as the efferent neuron, carries the nerve impulse from the CNS to the effector. Effector (F): The effector is the part of the reflex arc that carries out the response to the stimulus. It could be a muscle (resulting in a muscular contraction) or a gland (resulting in a secretion). Learn more about reflex action here: brainly.com/question/14495937 #SPJ2
