WebbThe mammalian diving reflex consists of a series of adaptive reflexes which occur after submersion in cold water. The physiologic purpose of the diving reflex is not well understood, but is believed to be oxygen conservation, a quality evident in diving mammals, in which the response is most pronounced. WebbThese physiological adjustments, which involve the nervous, cardiovascular, and respiratory systems, are known as the diving response and provide an ideal example of …

For one thing, it helps to conserve oxygen by slowing down our heart rate and directing blood flow to our vital organs. It also helps to protect our lungs from damage by constricting our blood vessels and reducing the amount of air that enters our lungs. high school band trip to disney world

WebbThe reflex arc is a negative feedback mechanism preventing too much tension on the muscle and tendon. When the tension is extreme, the inhibition can be so great it overcomes the excitatory effects on the muscle's alpha motoneurons causing the muscle to suddenly relax.

WebbA reflex occurs via neural pathways in the nervous system called reflex arcs. A stimulus initiates a neural signal, which is carried to a synapse. The signal is then transferred across the synapse to a motor neuron which evokes a target response.

It optimizes respiration by preferentially distributing oxygen stores to the heart and brain, enabling submersion for an extended time. The diving reflex is exhibited strongly in aquatic mammals, such as seals, otters, dolphins, and mu…
