Reflex action refers to the response to a stimulus, while reflex arch refers to the path taken by the reflex action.
<h3>What is the nervous system? </h3>
1. Low oxygen levels are detected by sensory receptors in the arteries.
2. An impulse is produced by sensory neurons.
3. Certain parts of the brain get an impulse from the central nervous system.
4. Motor neurons carry messages from the brain.
5. Isabel's respiration becomes more rapid.
Reflex actions are immediate, reflexive reactions to stimuli that limit bodily harm.
Therefore, it travels to the brain via the central nervous system and sends impulses via Isabel's motor neurons, which aid to speed up her breathing.

Answer:
Fibrous
Explanation:
Proteins are assembled according to their functions. Fibrous proteins usually provide protection and support to cells. They are made up of polypeptides that have elongated shape and assembles in large cables or threads. These proteins are differentiated from globular proteins by their globular form and repeated units of amino acids.
For example the fibrous proteins involved in horns, hair and nails is alpha-keratin. Elastin found in skin and ligament is also a fibrous protein. Collagen includes collagen fibrils that have tensile strength of steel is also a fibrous protein found in cartilages and bones.
