What is a contralateral response?

What is a contralateral response?

The crossed extensor reflex is contralateral, meaning the reflex occurs on the opposite side of the body from the stimulus. To produce this reflex, branches of the afferent nerve fibers cross from the stimulated side of the body to the contralateral side of the spinal cord.

What is ipsilateral response?

Both are examples of ipsilateral reflexes, meaning the reflex occurs on the same side of the body as the stimulus. The crossed extensor reflex is a contralateral reflex that allows the body to compensate on one side for a stimulus on the other.

What is the function of the contralateral and/or ipsilateral response?

Each afferent limb has two efferent limbs, one ipsilateral and one contralateral. The ipsilateral efferent limb transmits nerve signals for direct light reflex of the ipsilateral pupil. The contralateral efferent limb causes consensual light reflex of the contralateral pupil.

What is a Polysynaptic reflex?

Polysynaptic reflex channels are directed particularly toward flexor (withdrawal) responses through one or more interneurons to produce coordinated patterns of muscle activity to remove a portion of the body from a potentially damaging or offending stimulus.

When a contralateral response occurs What does this indicate about the pathways involved?

During initiating pupillary reflexes, what does the occurrence of a contralateral response indicate about the pathways involved? The pathways are connected contralaterally.

What is innate reflex?

Innate reflexes are genetically programmed and present in everyone’s body regardless of cultural, socio-economic, or neuro-physiological differences. Once an innate reflex becomes active, it automatically generates a motor response whenever the triggering response is present and without conscious or directed control.

What is the difference between an ipsilateral reflex and a contralateral reflex?

What is a reflex? Distinguish between an ipsilateral reflex and a contralateral reflex. ipsilateral reflex-response happens on the same side of the stimulus, contralateral reflex-response happens on the oppiste side of the body. Why is the flexor reflex an example of an intersegmental reflex arc?

When a contralateral response occurs What does this indicate about the pathways?

What are Intersegmental reflexes?

a reflex arc formed by fibers of sensory neurons or interneurons that travel from one spinal segment to another to communicate with motor neurons.

What is the purpose of the pupillary reflex?

The pupillary light reflex allows the eye to adjust the amount of light reaching the retina and protects the photoreceptors from bright lights.

What happens in Achilles reflex?

The Achilles reflex is a monosynaptic stretch reflex similar to the patellar reflex. In the Achilles reflex, the hammer taps the Achilles tendon while the foot is dorsiflexed, and the foot, in response, should jerk toward the plantar surface. The Achilles reflex originates in the S1 and S2 nerve roots.

What does contralateral mean in medical terms?

Ipsilateral (adjective) belonging to or occurring on the same side of the body. Contralateral (adjective) relating to or denoting the side of the body opposite to that on which a particular structure or condition occurs. “the symptom develops in the hand contralateral to the lesion”. Oxford Dictionary.

What is another word for ipsilateral?

Synonym (s): heterolateral. Pertaining to the opposite side. The term ipsilateral is used in referring to the same side. A term relating to the opposite side.

What is contralateral suppression in psychology?

Contralateral suppression may provide an objective and non-invasive clinical approach to study the MOCS and the descending auditory efferent pathways in the brainstem (13). Does the Efferent Auditory System Have a Role in Children with Specific Learning Disabilities?
