REFLEX ACTION

By Chipo James Mainda

When you touch a hot object or when a pin pricks your finger, what is your immediate reaction? Of course, you remove your hand away from the source of pain, either the hot object or the pin. In situations like these, your reactions are always immediate, involuntary and sudden. They happen without much of a thinking process. In scientific terms, this action is called the reflex action. Here the spinal cord has a major role to play. The reflex arc shows the pathway through which the reflex action occurs.

Reflex action is a sudden and involuntary response to stimuli. It helps organisms to quickly adapt to an adverse circumstance that could have the potential to cause bodily harm or even death. Pulling our hands away immediately after touching a hot or cold object is a classic example of a reflex action.

The whole mechanism of reflex action occurs in such a fashion that there is no conscious control of the brain. Stimulation occurs through the peripheral nervous system and the response to this peripheral nerve stimulation is involuntary. In a reflex action, the spinal cord along with the brain stem is responsible for the reflex movements.

A few examples of reflex action are:
* When light acts as a stimulus, the pupil of the eye changes in size.
* Sudden jerky withdrawal of hand or leg when pricked by a pin.
* Coughing or sneezing, because of irritants in the nasal passages.
* Knees jerk in response to a blow or someone stamping the leg.
* The sudden removal of the hand from a sharp object.
* Sudden blinking when an insect comes very near to the eyes.

There are some stimuli that require an automatic, instantaneous response without the need of conscious thought. The whole process of reflex action involves some important components. They are receptor organs, sensory neurons, nerve center and associated neurons in the spinal cord, motor neurons and effector neurons.

The sensory neurons pick up signals from the sensory organ and send them through other neurons which are interconnected. It is then received by the relay neuron which is present in the spinal cord. Immediately, the spinal cord sends back signals to the muscle through the motor neuron. The muscles attached to the sense organ move the organ away from danger. In reflex actions, the signals do not travel up to the brain.

What can you treat with low-level laser therapy?

✔Chronic Wounds
✔Acute Wounds
✔Surgical Wounds
✔Joint Pain
✔Joint Disorders
✔Neck Pain
✔Low Back Pain

Benefits from cold laser therapy:
✔Cell growth. Low-level laser therapy (LLLT) stimulates the division of the cells and their growth.
✔Wound healing. Cold laser therapy stimulates collagen production in fibroblasts which cause faster healing.
✔Increased metabolic activity. As red and near-infrared light increases the energy level of the cells.
✔Alleviation of pain or inflammation
✔Increased vascular activity and circulation. Cold laser therapy enhances the formation of new blood vessels in the treated area.
✔Stimulation of nerves recovery. After the injury limbs can feel numb, while cold laser therapy will stimulate reconnection of the nerves.

EKG Made Easy !💪💪💪

P wave - Atrial depolarization and contraction

QRS complex - Ventricular depolarization and contraction

T wave - Ventricular repolarization and relaxation

PR segment - Region between the end of the P wave and the start of the QRS complex - Primarily reflects the time in which the electrical impulse travels through the AV node and the atria are still depolarized and contracting during late diastole.

ST segment - Region between the end of the QRS complex and the start of the T wave - Primarily reflects the time in which the ventricles are depolarized, contracting, and pumping blood forward during systole.

TP segment - Region between the end of the T wave and the start of the P wave - Primarily reflects early diastole in which the heart is relaxed and filling with blood.

PR Interval - Duration of atrial depolarization .
