  • 2. a Sneezing; sensors in the nose; effectors in diaphragm, rib muscles and b Blinking; receptors in the retina of the eye; effectors, muscles in the eyelids. As with all reflexes, sneezing involves a reflex arc consisting of a receptor, a sensory nerve, an integration center, a motor nerve and an effector. Here's what. There is what's called the “reflex arc” which consists of a receptor, nerve, integration center, a motor nerve and an effector (HowStuffWorks).
    Physiological mechanisms exist to prevent over-inflation of the lungs.

    Mechanism of Cough and Sneeze MEDCHROME

    For the respiratory rate, the chemoreceptors are the sensors for blood pH, the medulla and pons form the integrating center, and the respiratory muscles are the effector. Main article: Sympathetic nervous system.

    Coughing or sneezing, because of irritants in the nasal passages. They are receptor organs, sensory neurons, nerve center, associated neurons, motor Effector organs are the glands and muscles that behave in response to the stimuli.

    coughing, sneezing and blinking of eyes are examples of reflex actions|| The reflex Effectors|| To understand reflex arc more clearly, let's take an example|| following things happen: the skin of our hands (receptors) feels the hotness of. Receptors in the nasal lining → Sneeze centre in the medulla → impulse It is then sent to the effectors such as pharynx, trachea, respiratory muscles, eyes.
    Start on. Main article: Sensory neuron. S: greater splanchnic nerves.

    Additionally, other structures may override voluntary respiratory signals, such as the activity of limbic center structures like the hypothalamus. The sensory part of the latter reaches the spinal column at certain spinal segments. The primary motor cortex is the neural center for voluntary respiratory control.
