The reflex arc is the sequence of events since a stimulus reaches the body, until the body reacts to it. The correct order is a, b, d, e, c.
The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts to it.
In general terms,
This mechanism is known as the reflex arc.
Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.
There are three types of neurons involved in the mechanism:
• Afferent or sensorial neurons
• Interneurons
• Efferent or motor neurons
Action:
1) The stimulus reaches the body and is received by the specialized sensory receptors.
2) Information is received by these receptors and converted from stimuli energy (temperature, pressure, light, etc.) to action potential energy.
3) Afferent neurons, placed in the dermis and epidermis, receive information from receptors, react and send the information to the central nervous system as nerve impulses.
4) Once the information reaches the central nervous system, it is processed by the interneurons that analyze it before sending a response.
5) Interneurons manage many sensorial signals, evaluate and compare them, and send a motor response.
6) Efferent neurons receive information from the interneurons and are stimulated to carry these new signals from the central nervous system to the cells of the effector organs. The effector organ can be a muscle or a gland.
7) Finally, the target tissue responds to the stimulus as a contraction, if it is a muscle, or as hormones release if it is a gland.
In the exposed example, the corrcet order is
a- A receptor detects a signal.
b- A sensory neuron sends a signal to the spinal cord.
d- A relay neuron sends a signal to a motor neuron.
e- A muscle receives a signal to contract.
c- A bone moves.
