A cranial reflex is one that is controlled by one of the cranial nerves and tend to take place in the facial or head area. These can include reflexes like the constriction of the pupils in response to light, etc. A spinal reflex, on the other hand, is a reflex that involves only the spinal nerves and is not processed by the brain. An example is the patellar reflex, like when the doctor hits your knee and it reflexively moves. Hope this helps! :)

What is the difference between cerebral reflex and a spinal reflex?
There are two major differences between the dura of the brain and the dura of the cord. The dura of the brain consists of two layers; the periosteal layer is attached directly to the inner surface of the skull and the meningeal layer is deep to the periosteal layer. In places, the two layers are fused together; in other places, dural sinuses lie between the two layers. There is no epidural space associated with the brain
What is cranial reflex?
A cranial reflex is a fast, involuntary response to a stimulus. It uses the brain stem as an integrating center (the brain receives sensory information and generates a response). This is contrasted to a spinal reflex, when the response is generated in the spinal cord itself, and the brain only finds out a reflex has occurred after the fact.An example of a cranial reflex would be the tracking movements of your eyes as you are reading this sentence. The dilation and contraction of your pupils in response to different levels of light is another cranial reflex.--------------An example of a spinal reflex would be standing on a pin or touching a hot object.
What is the section that demonstrates the continuity between the spinal and cranial cavities?
A midsaggital plane will show the continuity between the spinal and cranial cavities.
What is the connection between the cranial cavity and spinal cavity?
the brain stem
Which cavity contains the spinal and cranial cavities?
The cranial cavity contains the brain, pineal and hypophysis cerebri, parts of the cranial and spinal nerves, blood vessels, meninges and cerebrospinal fluid.
What is the difference between a simple spinal reflex and a complex reaction?
Simple spinal reflex is when the afferent receptor synapses directly with an efferent neuron and subsequently an effector cell/tissue. This will all take place in the spinal cord. A complex reaction will involve an intermediary interneuron or even the brain for 'processing' before synapsing with an efferent neuron and target tissue.
Is the knee-jerk reflex a simple reflex stretch reflex or a spinal reflex?
The knee-jerk reflex is a type of stretch reflex, which is a type of spinal reflex. It involves the stimulation of sensory neurons in the muscle spindles of the quadriceps muscle, leading to a quick contraction of the muscle in response to a sudden stretch.
What is spinal reflex therapy?
Spinal reflex therapy is a neurological soft tissue procedure that gets powerful and reliable results. You can learn more at Spinal Reflex Institute's website.
What contains the cranial nerve and spinal nerve?
Spinal Accessory Nerve
What control reflex?
spinal cord
Herniation of a cranial or spinal membrane?
meningocele
What type of reflex does not involve the brain?
A spinal reflex does not involve the brain. This type of reflex is controlled by the spinal cord and does not require the brain to initiate a response. Examples include the knee-jerk reflex and the withdrawal reflex.
