Jan 3, 2023 · The withdrawal response (reflex), also known as the nociceptive flexion reflex, is an automatic response of the spinal cord that is critical in protecting the body from harmful stimuli.

Jul 17, 2023 · The withdrawal reflex is defined as an automatic withdrawal of an extremity (e.g. a hand) from a painful stimulus. Unlike deep tendon reflex, the withdrawal reflex is polysynaptic. The basic mechanism by which it works is the following:

As examples, reflexes contribute to the maintenance of balance and rapid withdrawal of the hand or foot from damaging stimuli. Somatic reflexes can either be intrinsic (present at birth) or learned. We will be focusing on intrinsic reflexes, which occur as the result of normal human development.

Jan 6, 2025 · What is a somatic reflex? A somatic reflex is an involuntary response to a stimulus, such as pulling one’s hand away after touching a hot stove. The nervous system is split into the central nervous system (i.e., the brain and spinal cord) and the peripheral nervous system (i.e., nervous system outside of the brain and spinal cord).

Jan 3, 2023 · The withdrawal response (reflex), also known as the nociceptive flexion reflex, is an automatic response of the spinal cord that is critical in protecting the body from harmful stimuli.

Dec 19, 2013 · Noxious electrical stimulation of the digits in humans produces a coordinated reflex response that results in the withdrawal of the limb, akin to removing the hand from touching a hot stove 1, 2. This reflexive action, known as the nociceptive withdrawal reflex 3 , is an essential protective mechanism for interactions between parts of the body ...

You probably recognise the withdrawal reflex in the feet (standing on a nail) and hands (pulling away after touching a hotplate) but it operates throughout the body, even if the stimulus is not painful.

Application: • Withdrawal reflex of the hand from a painful stimulus. This browser cannot play the embedded video file. Skill: • Drawing and labelling a diagram of a reflex arc for a pain withdrawal reflex.

The withdrawal reflex refers to the withdrawing of a limb upon painful stimulation of the skin of the limb. The pain information is carried by Aδ pain fibers that synapse onto interneurons within the spinal cord.

4 days ago · Figure 38 | Crossed-extensor Reflex | 66 This figure illustrates the crossed-extensor reflex, a response that accompanies the withdrawal reflex to maintain balance and stability during a sudden withdrawal of a limb. Upon stimulation of nociceptors in the affected limb, sensory nerve fibers transmit signals to the spinal cord. The withdrawal reflex causes the flexor muscles of …
