How does the reflex arc protect the body
WebReflexes are involuntary, used to protect the body, and are faster than a reaction. Reflexes are usually a negative feedback loop and act to help return the body to its normal functioning stability, or homeostasis. The classic example of a reflex is one you have seen at your doctor's office: the patellar reflex. WebAn absent reflex response is also called areflexia. A reflex is an involuntary (automatic) action your body does in response to something. Reflexes protect your body from things that can harm it. Hyporeflexia results from any interruption of the reflex arc, which has a sensory part, a central part (spinal cord) and a motor part. Damage to any ...

WebSep 24, 2024 · A flexor reflex, which is also called a withdrawal reflex, is a multisynaptic reflex. It is a type of protective reflex where a painful stimulus triggers the contraction of flexor muscles. WebReflex actions are a special case. A true reflex is distinguished from other behaviours by mechanism; they do not go through the brain. Rather, the stimulus travels to the spinal cord and the message is then transmitted back through the body, tracing a path called the reflex arc. Reflexes are similar to fixed action patterns, but a fixed action ...
