Reflex Arc Diagram Labeled. The primary components of the reflex arc are the sensory neurons (or receptors) that receive stimulation and in turn connect to other nerve cells that activate muscle cells (or effectors), which perform the reflex action. They follow the following path:

A stimulus could be many things,. For example, a simple reflex arc happens if we accidentally touch something hot. The reflex act is an involuntary response to a stimulus, where the components i just mentioned interact. Web a reflex arc is not a series of actions but the structure that allows a reflex act to happen, and it comprises (in a sequential order) a stimulus, a receptor, an afferent pathway, a synapse, an efferent pathway, an effector and a response. They produce some chemicals when electrical signals reach them. Use the diagram) word bank: The reflex arc typically consists of five components: Web start studying anatomy: Spinal cord sensory (afferent) neuron motor (efferent) neuron Web the junctions between neurons through which the signals can be sent are called the chemical synapses.
Web reflex arc, neurological and sensory mechanism that controls a reflex, an immediate response to a particular stimulus. Web reflex arc, neurological and sensory mechanism that controls a reflex, an immediate response to a particular stimulus. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This characteristic allows reflex actions to occur relatively quickly by activating spinal motor neurons without the delay of routing signals through the brain, although the. Web all reflexes follow a reflex arc, which is made up of the components of a reflex. The receptor is present in the receptor organ. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The primary components of the reflex arc are the sensory neurons (or receptors) that receive stimulation and in turn connect to other nerve cells that activate muscle cells (or effectors), which perform the reflex action. They produce some chemicals when electrical signals reach them. This is what initiates the reflex. Web the path taken by the nerve impulses in a reflex is called a reflex arc.
