Reflex

protection but what also needs to be trained is your response to a sudden attack or what is known as the startle response. ***** The startle response (also known as the startle reflex and the alarm reaction) is an involuntary reaction to an external stimuli such as a loud noise or a sudden threatening movement. The reflex is set off by stimuli to the brain stem which is located at the base of the skull at the top of the spinal cord. The brainstem controls the involuntary functions of the body…

Response, which can be also known as ‘The Mammalian Dive Response/Reflex. The Diving reflex consists of set of reflexes that are activated when our face is cooled or if we hold our breath. This is a clever psychological mechanism because it enables our bodies to manage and to tolerate a lower level of oxygen in an environment that we do not normally face every day. There are three main changes that occur in our body when our Dive reflex triggers; Bradycardia, Peripheral vasoconstriction and…

The purpose of this experiment is to investigate the heart rate through the dive reflex Homeostasis is the body’s ability to maintain and balance its normal body function in varying conditions. The autonomic nervous system relates to the peripheral nervous system. Its objective is to sustain homeostasis of the visceral organs. In this investigation we will observe the mammalian diving reflex, which implicates the autonomic nervous system. In mammals, immersing the face in water initiates…

The isometric contraction showed that when the brain is occupied by an action the reflex arc will then take over and allow a different muscle to still contract. The Jendrassik maneuver was shown to decrease the response component from the onset of the stretch in both extensor and flexor muscles (Nardone & Schieppati, 2008). In the experiment…

organs of mammals and gave a big impact on physiology area.. Pavlov created the right way for an objective science of behavior (Pavlov’s dog 2014). In this Pavlov’s dog experiment, he used the conditioned reflex with object’s stimulus. Thus, we will know if we can train them with conditioned reflex. Pavlov’s portrayal of how human and animals can be conditioned to respond in certain ways to specific stimuli. Thus, he discovered the way for new and objective ways to study human and animal…

How would an untrained person conduct themselves if he encountered a fight? Some may be fine in a fight because they are innately strong and could intimidate the attacker and others are good at running away and avoiding the fight all together. However, some will not know what to do in that type of situation in light of that they have never been taught. The defender would have to rely on his unaccustomed instincts and what he has seen throughout his life, which would be mainly be action movies…

neurologist or audiologist. If such problems arise, the patient should be referred to an ENT or audiologist. To test cranial nerve IX, the gag reflex involves a brisk and brief elevation of the soft palate and bilateral contraction of pharyngeal muscles evoked by touching the posterior pharyngeal wall. It is tested on the left and the right sides and the reflex response should be consensual (i.e., the elevation of the soft palate should be symmetrical regardless of the side touched). Unilateral…

medical tests for testing the responsiveness of the brain stem include pupil response tests, corneal reflex test, oculocephalic test, oculovestibular test, oculopharyngeal reflex test, and the apnea test (Miller and Truog, 2012). A pupil response examination where the physician shines a bright light at the eye and reviews pupil dilation or the absence thereof (Miller and Truog, 2012). A corneal reflex test examines the responsiveness of a patient when a cotton swab touches the cornea; a typical…

It particularly concerns the Satiety Reflex. The Satiety Reflex is what “makes you feel full as you eat greater amounts of food” (Glatter 2). Eventually, you will get full because of this reflex. Competitive Eaters never get full, because they can “overcome the ‘satiety reflex’” (Glatter 2). In addition, the Journal of Roentgenology said “there was little to no contractions (peristalsis) of the stomach itself…

newborn comes well equipped for the early days of survival by having a series of reflexes that help it coordinate eating, sleeping, and other necessary processes at this unwieldy stage. The most common and prominent reflexes include: • Blinking: This reflex will obviously stay with your baby for life – could you imagine if you had…
