What does ipsilateral reflex and contralateral reflex mean?
The stimulus was presented either to the same ear as the compliance probe ( ipsilateral reflex) or to the opposite ear (contralateral reflex). Medical browser ? Full browser ?
What is an example of a single synapse reflex?
This is a rapid, monosynaptic (single synapse), ipsilateral reflex that helps to maintain the length of muscles and contributes to joint stabilization. A common example of this reflex is the knee jerk reflex that is elicited by a rubber hammer striking against the patellar tendon, such as during a physical exam.
What is a reflex action called?
A reflex action, also known as a reflex, is an involuntary and nearly instantaneous movement in response to a stimulus. When a person accidentally touches a hot object, they automatically jerk their hand away without thinking. A reflex does not require any thought input. The path taken by the nerve impulses in a reflex is called a reflex arc.
What is an example of the knee jerk reflex?
A common example of this reflex is the knee jerk reflex that is elicited by a rubber hammer striking against the patellar tendon, such as during a physical exam. When the hammer strikes, it stretches the tendon, which pulls on the quadriceps femoris muscle.
Is the knee jerk reflex ipsilateral?

Is withdrawal reflex ipsilateral or contralateral?
Crossed Extensor Reflex: The crossed extensor reflex is a withdrawal reflex where the contralateral (opposite side) limb makes up for the loss of support created when the ipsilateral (same side) limb withdraws from a painful external stimulus.
What is an ipsilateral response?
a reflex in which the response occurs on the side of the body that is stimulated.
What are some examples of spinal reflexes?

What kind of reflex is the knee jerk or patellar reflex?
stretch reflexThe patellar reflex, also called the knee reflex or knee-jerk, is a stretch reflex which tests the L2, L3, and L4 segments of the spinal cord.
What is the difference between ipsilateral and contralateral reflexes?
Ipsilateral means 'same side' and contralateral means 'opposite side'. The reflexes are always indicated by the probe ear. For both pathways, the loud sound travels through the outer, middle, and inner ear, then along the vestibulocochlear nerve (CNVIII) to the brainstem arriving at the cochlear nucleus.
What is ipsilateral and contralateral?
Contralateral: Of or pertaining to the other side. The opposite of ipsilateral (the same side).
What type of reflex is the withdrawal reflex?
polysynaptic reflexThe withdrawal reflex is a spinal reflex intended to protect the body from damaging stimuli. It is a polysynaptic reflex, causing stimulation of sensory, association, and motor neurons.
What are the 4 types of reflexes?
We have different types of reflexes in the body. Four key examples are the stretch reflex, the flexor reflex, the crossed-extensor reflex, and the Golgi tendon reflex.
What is an example of flexor reflex?
Spinal Cord Motor Functions; the Cord Reflexes The left-hand portion ofFigure 55-9 shows the neuronal pathways for the flexor reflex. In this instance, a painful stimulus is applied to the hand; as a result, the flexor muscles of the upper arm become excited and withdraw the hand from the painful stimulus.
What is contralateral reflex?
A contralateral reflex is a reflex in which the response occurs on the opposite side of the body that is stimulated
What is a reflex response?
A reflex is a predictable involuntary response to a stimulus ( your hand touches fire, it pulls away)
What is a crossed extensor reflex?
A crossed extensor reflex is a single sensory input that brings about many motor responses on the other side of the body
What is tendon reflex?
A tendon reflex is a protective reflex for muscles, which means when too much pressure is felt on a tendon, the muscle will relax.
What is withdrawal reflex?
A withdrawal reflex is a single sensory input that brings about many motor responses on the same side of the body.
Is monosynaptic reflex ipsilateral reflex?
monosynaptic and it is a ipsilateral reflex
