What is the significance of ciliospinal reflex?
The ciliospinal reflex (pupillary-skin reflex) consists of dilation of the ipsilateral pupil in response to pain applied to the neck, face, and upper trunk. If the right side of the neck is subjected to a painful stimulus, the right pupil dilates (increases in size 1-2mm from baseline).
Is the ciliospinal reflex sympathetic or parasympathetic?
sympathetic nervous system
In the absence of anesthesia, this response has been called the ciliospinal reflex and is primarily mediated by the sympathetic nervous system in both humans [1,2]and cats.
What is the response of the ciliospinal reflex quizlet?
The ciliospinal reflex is kind of bizarre in that the sensory receptors do not involve any structures in the eye. This reflex is initiated by gently stroking the skin at the hair line on the back of one side of the subject’s neck. This results in the dilation of the pupil on the ipsilateral side of the stimulus.

What is the result of a somatic reflex?
A somatic reflex is an involuntary movement in response to a stimulus. To produce the action, the somatic reflex arc is activated when a signal from the stimulus is sent to the muscle cells, passing through afferent neurons to the CNS, and finally, to the efferent neurons.
What is the difference between an autonomic reflex and a somatic reflex?
Autonomic reflexes are not subject to conscious control, are mediated by the autonomic division of the nervous system, and usually involve the activation of smooth muscle, cardiac muscle, and glands. Somatic reflexes involve stimulation of skeletal muscles by the somatic division of the nervous system.
What type of reflex is the ciliospinal reflex quizlet?
What division of the autonomic nervous system is responsible for the ciliospinal reflex?
Answer and Explanation: ciliospinal reflex – The ciliospinal reflex occurs by the action of the sympathetic nervous system.
Is a knee-jerk autonomic or somatic?
Autonomic Reflexes Activity 1- Patellar reflex The patellar tendon reflex or knee-jerk reflex is a monosynaptic stretch reflex that assesses the nervous tissue between (and including) the L2 and L4 segments. It can be done by tapping the patellar ligament (just below the knee) with a reflex hammer.
Is the Ciliospinal reflex somatic or autonomic?
What is the ciliospinal reflex test?
What does the Ciliospinal reflex test? The ciliospinal reflex (pupillary-skin reflex) consists of dilation of the ipsilateral pupil in response to pain applied to the neck, face, and upper trunk. If the right side of the neck is subjected to a painful stimulus, the right pupil dilates (increases in size 1-2mm from baseline).
What is a reflex reflex test for knee pain?
Reflex Test: Understanding the Knee-jerk Response and What the Test Can Tell You. Outline: Reflex tests help assess the integrity of nerve circuits and are performed to confirm the integrity of the spinal cord, or specific nerve root function.
What is the pathophysiology of exaggerated ciliospinal reflex?
The exaggerated ciliospinal reflex may lead to bilaterally dilated pupils which remain dilated for 1 to 6 minutes with minimal or no response to brief exposure to light (seemingly non-reactive pupils) or in pupillometry.
What is a reflex test for spinal cord?
Synopsis: Reflex tests help assess the integrity of nerve circuits and are performed to confirm the integrity of the spinal cord, or specific nerve root function. The knee-jerk response is any kind of reaction that is done automatically, without thought, and is one of the fastest and most primitive in the human body.
