Reflex - Instinct A reflex action, differently known as a reflex, is an involuntary and nearly instantaneous movement in response to a stimulus.Scientific use of the term reflex refers to a behavior that is mediated via the reflex arc; this does not apply to casual uses of the term reflex. reflex action, differently known as a reflex, is an involuntary and nearly instantaneous movement in response to a stimulus.

What Is an Example of a Reflex Action? A reflex action occurs when the body responds to a stimulus without the involvement of the brain. Batting of eyelids and rapid withdrawal of hands from a hot surface are examples of reflex actions. The contraction of the pupils of the eyes when exposed to bright light is a perfect example of a reflex action.

Positive Health Online All these 'reflex' reactions occur when muscles contract in response to an obvious external stimulus. The reality is, outside forces are stimulating our muscles every time we move, run, jump, walk, throw, catch, get out of bed, or hold our head up, and our reflexes govern our reactions to those forces.

- 10 most extreme places on Earth. A stretch reflex, also referred to as a deep tendon reflex or myotatic stretch reflex, is a physical response to the extension of a muscle. In essence, it is a process that causes a contraction, thereby stopping a stretch.he stretch reflex prevents people from overextending their muscles. Protective response is what prevents muscles from being stretched too far. Before a workout, take time to gently and slowly stretch the muscles in order to help prevent any muscle damage.

reflex a reflected action or movement; the sum total of any particular automatic response mediated by the nervous system. A reflex is built into the nervous system and does not need the intervention of conscious thought to take effect.

Reflex - Instinct Definitions: reflex and instinct. A reflex action, also known as a reflex, is an involuntary and nearly instantaneous movement in response to a stimulus. A true reflex is a behavior which is mediated via the reflex arc; this does not apply to casual uses of the term 'reflex'.A reflex arc is a neural pathway that controls an action reflex. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. true reflex is a behavior which is mediated via the reflex arc; this does not apply to casual uses of the term 'reflex'.

Reflex tests A reflex is a simple nerve circuit. A stimulus, such as a light tap with a rubber hammer, causes sensory neurons (nerve cells) to send signals to the spinal cord. Here, the signals are conveyed both to the brain and to nerves that control muscles affected by the stimulus.

reflex reflex. a reflected involuntary action or movement; the sum total of any particular automatic response mediated by the nervous system. A reflex is built into the nervous system and does not need the intervention of conscious thought to take effect. positive reaction is a sharp contraction of the muscle of which the tendon is part. The patellar reflex is the best known of these reflexes. Absence indicates a defect in the reflex arc, an exaggerated response suggests an upper motor neuron lesion. Called also myotactic reflex.

Reflexes Describe the components of a reflex arc. 1  Reflexes, or reflex actions, are involuntary, almost instantaneous movements in response to a specific stimulus.  Reflex arcs which contain only two neurons, a sensory and a motor neuron, are considered monosynaptic.

Reflexes A reflex arc is a neural pathway that controls a reflex action. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord.n the case of peripheral muscle reflexes (patellar reflex, achilles reflex), brief stimulation to the muscle spindle results in contraction of the agonist or effector muscle. By contrast, in polysynaptic reflex pathways, one or more interneurons connect afferent (sensory) and efferent (motor) signals.

Neurological Exams: Sensory Nerves and Deep Tendon Reflexes The normal response is a ‘knee jerk’. This is an example of a reflex, which is an involuntary muscular response elicited by the rubber hammer tapping the associated tendon. When reflex responses are absent this could be a clue that the spinal cord, nerve root, peripheral nerve, or muscle has been damaged.When reflex response is abnormal, it may be due to the disruption of the sensory (feeling) or motor (movement) nerves or both.To determine where the neural problem may be, the physician tests reflexes in different parts of the body.See the following examples in the chart below.hen reflex response is abnormal, it may be due to the disruption of the sensory (feeling) or motor (movement) nerves or both.

What is an example of instinctive behavior in HUMANS? Report Abuse. Reflexes and instinctual knowledge are not the same thing. Humans have reflexes especially as infants but they are simple motor reflex arcs such as an infant's rooting response to a touch on its cheek. An infant automatically responds, it opens its mouth and turns into the stimulus. If milk is found there is an involuntary sucking/swallowing reflex.

Large for Gestational Age (LGA) LGA babies have birthweights greater than the 90th percentile for their gestational age, meaning that they weigh more than 90 percent of all babies of the same gestational age. The average baby weighs about 7 pounds at birth. About 9 percent of all babies weigh more than 4,000 grams (8 pounds, 13 ounces). Rarely do babies weigh over 10 pounds. Although most LGA babies are born at term (37 to 41 weeks of pregnancy), a few premature babies may be LGA.

Primitive reflexes Primitive reflexes are reflex actions originating in the central nervous system that are exhibited by normal infants, but not neurologically intact adults, in response to particular stimuli. These reflexes are absent due to the development of the frontal lobes as a child transitions normally into child development.rimitive reflexes are reflex actions originating in the central nervous system that are exhibited by normal infants, but not neurologically intact adults, in response to particular stimuli.

reflex The knee jerk is an example of the simplest type of reflex. When the knee is tapped, the nerve that receives this stimulus sends an impulse to the spinal cord, where it is relayed to a motor nerve. This causes the quadriceps muscle at the front of the thigh to contract and jerk the leg up.
