Sensory receptor, sensory neuron, interneuron, motor neuron, and muscle.
The short pathway that carries the impulse for an automatic response is called a reflex arc. It involves sensory neurons, interneurons in the spinal cord, and motor neurons to quickly produce a reflex action in response to a stimulus, bypassing the brain.
reflex arc
The simplest pathway of an impulse involves the sensory neuron transmitting a signal to the interneuron in the spinal cord, which then relays the signal to the motor neuron, causing a response in a muscle or gland. This pathway is known as a reflex arc and allows for rapid, automatic responses to stimuli without involving the brain.
Reflex Arc
To remember the stages of a reflex arc in chemistry, you can use the acronym "SAID" which stands for stimulus, afferent pathway, integration center, and efferent pathway, and then the response. This mnemonic can help you recall the order of events in a reflex arc.
The pathway that the nerve impulse takes from your foot to your leg is called the sensory pathway. This pathway includes sensory neurons that carry signals from the foot to the spinal cord and then to the brain, where the sensation of pain is perceived and a motor response is initiated to move away from the tack.
The neural pathway of a single reflex is called a reflex arc. It involves the sensory neuron carrying information from the receptor to the spinal cord, where it synapses with a motor neuron that carries the response signal to the effector muscle or organ. This simple pathway allows for rapid, involuntary responses to stimuli.
Reflexes are rapid involuntary responses to a given stimuli. The reflex pathway that only has one synapse in the CNS is called the monosynaptic reflex arc.
nociceptors and mechanoreceptors (respond to touch, temp and pain)
A reflex arc doesn't go all the way up to the brain. Thus it NEVER becomes part of the thought process.
The speed of impulse in a reflex arc can vary, but it is usually very fast, allowing for quick responses to stimuli. In general, impulses can travel at speeds of up to 100 meters per second along myelinated nerve fibers.
They are neurons and not neutrons. You have afferent neuron. Then you have intermediate neuron and then you have the efferent neuron in the reflex arc.
