To shield yourself in the event of a bear attack (just kidding.) You pull one arm back to protect it from damage, but at the same time you extend the opposite arm to help retain your balance. Also effective for fighting criminals.

If the upper limbs are involved, extension of the opposite limb acts to push the stimulus away. If the lower limbs are involved, extension of the opposite limb prepares the limb to receive the body weight.

Is the corneal reflex a somatic reflex or an autonomic reflex?
This particular reflex is autonomic as the affected muscle, constrictor pupillae muscle, is a smooth muscle and not under conscious control. Typically if you can consciously contract the muscle, any reflex associated with that muscle is somatic in nature.
What is a bilateral reflex?
The best examples of this is to shin a light in one eye and both pupils constrict. You are testing cranial nerve II.Or the corneal reflex (touch one cornea) both eyes blink, a test of CN VII or the palpebral reflex, touch one eye lid or lashes and both eyes blink, another test of CN VII.
What reflexes classified as somatic reflexes?
There are 5 somatic reflexes, stretch (spinal), crossed extensor (spinal), superficial cord (spinal), corneal (cranial), and gag (cranial).Involuntary automatic responses to sensory stimulation, for example, the knee-jerk reaction when tapped.Note: Reflexes, such as the contraction / dilation of the pupil, salivation when hungry are all controlled by autonomic reflexes.
Is the knee-jerk reflex a simple reflex stretch reflex or a spinal reflex?
spinal reflex
The patellar reflex is a type of?
knee jerk aka patellar reflex is an example of a stretch reflex
The protective aspect of the corneal reflex?
To protect the eye from external damage.
What is corneal reflex somatic?
yes it is somatic
What neural injury will the corneal reflex not test for?
damage to cranial nerve II
Reflexes classified as somatic reflexes include?
A. abdominal reflex B. Achilles jerk D. corneal reflex E. crossed extensor reflex F. gag reflex G. patellar reflex H. plantar reflex
Is Corneal reflex involve both eyes or just one eye?
both eyes
A cranial reflex that is often used to test the sensory function of the trigeminal nerve is the?
corneal
What are the cranial nerves involved in the corneal reflex?
It is the 7th cranial nerve (facial nerve).
What is an automatic response that involves only part of an organism?
A reflex is an automatic response that only involves one part of an organism's body. Examples include the pupillary light reflex, patellar reflex and corneal reflex.
Is the corneal reflex a cord-mediated reflex?
The corneal reflex may be elicited by lightly touching the cornea with a wisp of cotton; this sensory stimulus is transmitted by the first branch of the trigeminal nerve to the brainstem. There, thanks to connections of the trigeminal nerve with the facial (motor) nerve, a motor response occurs leading to contraction of the orbicularis oculi. The result is blinking or closing the eye on the same side. Thus this reflex is a brainstem and not a cord-mediated reflex.
A protective reflex stimulated by foreign material in the trachea or bronchi is the?
This is called the gagging or the coughing reflex
Why do goats fake death when attacked?
It's a natural protective reflex.
What is a protective reflex that also overrides the spinal pathways and prevents any other reflexes from using them at the same time?
Flexor Reflex
