Are reflexes automatic responses?

Are reflexes automatic responses?

A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain. The reflex is then an automatic response to a stimulus that does not receive or need conscious thought.

Is response to pain a reflex?

Painful stimuli are classified as central (response via the brain) or peripheral (reflex response via the spine).

What is a pain reflex?

Reflex pain is a complex condition that occurs when the body’s pain withdrawal reflex fails to disappear long after the triggering event. The neurological phenomenon, known as the withdrawal reflex, occurs when the body executes a chain of reactions to remove an affected body part from painful stimuli.

What are automatic reflexes?

A reflex is an involuntary (say: in-VAHL-un-ter-ee), or automatic, action that your body does in response to something — without you even having to think about it. You don’t decide to kick your leg, it just kicks. There are many types of reflexes and every healthy person has them. In fact, we’re born with most of them.

What are the pain pathways?

The medial thalamus projects to widespread areas of the forebrain, including the somatosensory cortex (Jones and Leavitt, 1974). Thus there are two major ascending pathways for pain: a direct lateral spinothalamic pathway and an indirect medial spinoreticulothalamic pathway.

What are some examples of involuntary movements?

Examples of uncontrollable movements are:

• Loss of muscle tone (flaccidity)
• Slow, twisting, or continued movements (chorea, athetosis, or dystonia)
• Sudden jerking movements (myoclonus, ballismus)
• Uncontrollable repetitive movements (asterixis or tremor)

What is an example of a autonomic response?

The Autonomic Nervous System The ANS affects heart rate, digestion, respiratory rate, salivation, perspiration, pupillary dilation, micturition (urination), and sexual arousal. Everyday examples include breathing, swallowing, and sexual arousal, and in some cases functions such as heart rate.

How does the body respond to pain?

The body responds to pain through numerous and interconnected physiolog-ical processes via the sympathetic nervous system (SNS), neuro-endocrine system and immune system, but also via emo-tions. The effects of these changes on body systems are summarised in Table 1.

What is the body’s adaptive response to pain?

The body’s adaptive response to pain involves physiological changes, which are useful and potentially life-saving in the initial stages. If the adaptive response persists, harmful and life-threatening effects may ensue.

What happens to the body after a pain stimulus is transmitted?

The initial physiological changes taking place in the body after a pain stimulus are concerned with the transmission of pain, which involves four stages: transduction, transmission, perception and modulation. During transduction, the pain stimulus is transformed into a nerve impulse.

What are some examples of automatic responses in the body?

Each breath you take automatically readjusts to provide the right balance of oxygen and carbon dioxide in your blood, as well as taking deeper breaths now and then to keep the lungs open. These are just a few examples of the automatic responses that keep us functioning every day.
