Sometimes people go to a doctor appointment and they get their knee with a small rubber hammer? Or they go to the eye doctor and had them put drops in their eyes to dilate their pupils? These are all in some way connected to a reflex.
Reflexes A reflex is an involuntary, or nearly instantaneous movement in response to a change in the environment. Reflexes are done without having to think about it. All healthy people are born with most reflexes that can help to protect themselves from harm.
Reaction versus Reflexes Reactions and reflexes are two different types of responses. A reaction is a choice that is made by mentally making a decision. On the contrary, a reflex is instinctive and automatic. A reaction goes through the sensory

The grasp appears at birth but only continues for another five or six months. This reflex occurs if a finger is placed on their open palm. The infant 's hand will close around the finger and trying to remove the finger causes the grip to tighten. Newborn infants have strong grasps and can almost be lifted up if both hands are grasping fingers! The moro reflex, also called the startle reflex, is likely to occur if the following happen: the infant 's head suddenly shifts in position, the temperature changes abruptly, they are startled by a sudden noise, or the sensation of falling takes place. Even the baby 's own cry may cause this reflex! The legs and head extend while the arms jerk up and out with the palms up and thumbs flexed. The step reflex is sparked when the sole of the foot touch a hard surface. The infant then lifts one foot, then the other, as if walking.
Children and Adult Reflexes Many infant reflexes continue into toddlerhood and some stay with people all of our lives. Adults and children have reflexes such as the following: the accommodation reflex, acoustic reflex, pupillary light reflex, brachioradialis reflex, deep tendon reflex, and patellar reflex. These reflexes can help our bodies to stay protected and safe.
Accommodation Reflex The accommodation reflex is an action of the eye in response to focusing on a object, whether it is looking at a near object and then focusing on a far object or vice versa. This
In the case of,” 7 year old Antonio, after recovering from a bad flu, at a nearby hospital, would notices having stomach pain, when passing the area of the hospital.” Therefore, Antonio, experience, a case of the Conditioned Response (CR); in this case a learned connection and associations with being in the hospital, feeling sick with the flu, which is a general process, acquisition. Yet, has a Conditioned Stimulus (CS), “ During acquisition, the neutral stimulus begins to elicit the conditioned response, and eventually the neutral stimulus becomes a conditioned stimulus capable of eliciting the conditioned response by itself.” OpenStax College. (2015). Learning. In Psychology (chapter 6)
Reflexology is an alternative treatment that rests on the applying pressure of specific areas on the feet, hands and ears. All these pressure points are believed to correlate with internal body functions and organs. Applying pressure on these pressure points encourages proper energy flow throughout the body and facilitates self-healing.
Babies at birth – most are born at 40 week and premature babies more often need a little more time to reach the same level of development as babies born in and after the 40th week. Most are born with just reflexes for survival at first. These would be swallowing, sucking reflexes to help feed. Rooting reflex baby will move its head if the cheek is touched to find a nipple or teat. Grasp reflex babies will grip objects touching their palm. Startle reflex they will often move arms outwards and clench fists is a sound movement or light suddenly startles them. Walking reflex when babies are held upright with their feet on a
At birth surprisingly a child has intellectually learned to do things already such as smell their mother and recognise her voice. They have also learnt that when they cry it lets people know that they need help and within the first few days of life they learn to use their senses particularly touch, taste and sound. At infancy a child is expected to weigh around 3.5kg or 7 1/2lbs and 50cm long. Bonding is very important socially and emotionally for both mother and baby, helps relationship in later life because they become closer. The babies reflexes are now improving, some of them are automatic responses. E.g. sucking a nipple or a bottle. Grasp reflex is when a
Startle reflex- when babies hear a sudden sound or see a bright light, they move their arms outwards, and clenching their fists
One way reflexology may work is by relaxing the body and relieving stress, which encourages natural healing and regeneration. Another theory is that it works with the central nervous system, taking advantage of the connections between peripheral nerves, skin and internal organs. The application of pressure to specific points sends a message to peripheral nerves to adjust the corresponding areas tension level, improve circulation, stimulate
Science, as yet, has not been able to confirm how reflexology works. Here I explore the theories surrounding reflexology.
* Reaction - also known as a reflex is an involuntary and nearly instantaneous movement in response to a stimulus.
Plantar reflex is when infants curl their toes when pressuring the sole of the foot (Leifer, 2014).
Reflexes protect us from danger, a reflex is a reaction from a muscle that happens instantly in response to stimulation.Without studying reflexes we won't know if a human begin nervous system development and function is working properly.Reflexes allow us to understand the body and how it's work, also it allows us to figure out clues that our spinal cord, nerve root could be damaged or our sense of feeling is off.One clinical application is the testing of these reflexes one is called Babinski which id the stroking of infants foot on the lateral side.Another one is cremasteric reflex which is the stroking of skin if the upper thigh.Ankle jerk reflex is also one which the tap to calcaneal tendon to see the reaction from tibia nerve.One simple
In chapter three I found reflexive behavior to be quite interesting it spoke about the different components by describing “reflex” in which there are more types of reflexes than just an average reflex. It begins to talk about the laws of the govern pupil contracting when a light is shone in an eye from the basic principles that describes the relationship between a loud noise and quick sudden response can hold the salvation producing unconsciousness from eating a meal. Moreover, Sherrington who discovered the variety of stimulus-response relationships by focusing on the reflex. By giving an example of when a dog (human-being) mouth, when food enters the mouth it instantly causes the salivary glands to produce saliva. The relationship between food entering the mouth and salivation is what is known as a “reflex” that is based on the genetic endowment of the organism in which isn’t learned. Conversely, many
Reflexes are a nerve responses that are not supervised by the brain but are rather designed to answer in a definite way to assure your bodies safeguard. The nerves are stimulated which relays a signal to the spinal cord and a nerve loop in the spinal cord relays a message back to cause the reflex without the engagement of the brain. Some examples of reflexes would be someone touching a hot stove while cooking and quickly jerking their hand back would be the reflex or when going to the doctor's office and they hit you on the knee and your leg kicks out would be another form of a reflex.
A reflex action is defined as an involuntarily, nearly instantaneous, movement in response to a stimulus (Boundless, 2016). A reflex action is a response that does not need any thought input. For example, when a person accidentally touches a hot object, the automatic response that results is that they move their hand away without even thinking. With that being said, the path that is taken by the nerve impulse in a reflex action is called a reflex arc (Boundless, 2016). The main components that make up the “reflex arc”, as depicted in the image below, consist of the receptor, afferent or sensory neuron, integration centre, and the efferent or motor neuron. A reflex action can be initiated by various stimuli such as internal or external stimuli. An internal stimulus is that which is from within the organism itself whereas an external stimulus is that which is occurs outside the organism. When it comes
There are two groups of reflexes in the human body, with two ways to categorize each of them. Reflexes can either be inborn and connected through the nervous system, or they can be learned through practice. Another way to explain a reflexive category would be autonomic reflexes or somatic reflexes. Autonomic reflexes are those which are unaware to us and act on visceral organs of the body, whereas somatic reflexes involve skeletal muscle stimulation. Both types of reflexes are put into effect via the nervous system. (1)
There is evidence that reflexology has been around for many centuries and practiced by many different cultures including Chinese and Egyptians (Gillanders 2008, Mei-Yeh, Pei-Shan, Pi-Hsia, Wen-Yin,Che-Ming, 2008). “Archeologists have uncovered various pictures in tombs of ancient Egyptians working on what is believed to be patient’s hands and feet” (Gillanders pg. 12). Reflexology dates back to 2330 BCE, and has become a very sought after healing treatment for patients of many different illnesses. “In the 4th century, a Chinese acupuncturist called Dr. Ko Hung discovered that using his thumbs to apply a deep pressure to the soles of the feet while acupuncture needles were in the place was a means of enhancing healing and encouraging energy to be released”. Sometimes reflexology is still referred to as “acupuncture without the use of needles” (Gillanders pg. 12). It has only become popular in the United States last in the 100 years. Zone therapy was the precursor to modern reflexology, which was reborn through the work of William H Fitzgerald MD in the early 20th century. He was an ear, nose, and throat specialist in the Boston City Hospital in Connecticut. Dr. Fitzgerald discovered that by applying pressure to the tops of the fingers with metal clamps, and winding tight elastic bands around the middle section of each finger, he created an anesthetic effect on the facial area. By this, he was able to do simple ear, nose, and throat surgery without any anesthesia.
