Reflexes require stimulation—they are not spontaneous actions like muscle tics but responses to sensory input. reflexes are quick—they generally involve only a few interneurons, or none, and minimum synaptic delay.
Excerpts From Frankenstein Pdf Science Laughter Describe reflex responses in terms of the major structural and functional components of a reflex arc. distinguish between each of the following pairs of reflexes: intrinsic versus learned, somatic versus visceral, and ipsilateral versus contralateral. During a reflex, messages about pain or temperature don’t travel all the way to and from the brain. instead, they travel only as far as the spinal cord, and the spinal cord responds to the messages by giving orders to the muscles. The cough reflex is caused by an irritant in the trachea and the sneeze reflex by one in the nose. in both, the reflex response involves many muscles; this includes a temporary lapse of respiration in order to expel the irritant. If, for example, you step on something painful, the reflex will be to lift the injured foot. the sensory information that initiates this reflex is activation of pain receptors, or nociceptors. like with the stretch reflex, the sensory information enters the spinal cord at the dorsal horn.

This document lists and briefly describes over 40 human reflexes, including primitive reflexes only present in infants. it discusses the diving reflex in depth, noting it optimizes oxygen distribution to vital organs during submersion. When injurious stimuli are applied to the skin, there is reflex withdrawal of the skin from the source of the injury. the sensory receptors in skin that mediate this reflex are known as nociceptors, a type of receptor that senses different types of noxious stimuli. Because reflexes are quick, it makes sense that somatic reflexes are often meant to protect us from injury. as examples, reflexes contribute to the maintenance of balance and rapid withdrawal of the hand or foot from damaging stimuli. In this article we will discuss about the definition and properties of reflex. definition of reflex: a reflex is defined as automatic involuntary, stereotyped repetitive, purpose serving or goal oriented response for afferent stimulation which can be internal or external.
