Where is the Integration Center located for most autonomic reflexes?
Integration center The main integration centers for the autonomic reflexes are located in the hypothalamus and the brain stem. Some autonomic reflexes are situated in the integration centers of the spinal cord, which are mostly responsible for urination and defecation.
What is the integration center of a reflex arc?
An integrating center, the point at which the neurons that compose the gray matter of the spinal cord or brainstem synapse. Efferent nerve fibers carry motor nerve signals from the anterior horn to the muscles. Effector muscle innervated by the efferent nerve fiber carries out the response.
Where is the integration center and what happens there?
An integration center consists of one or more synapses in the CNS (typically the spinal cord) where the incoming information and outgoing response are integrated. A motor, or efferent, neuron sends a nerve impulse along an efferent pathway from the integration center to an effector cell.
What is the difference between a cranial and spinal reflex?
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. A spinal reflex, on the other hand, is a reflex that involves only the spinal nerves and is not processed by the brain.
Are nerves organs?
That suggests it is made of two organs—and you may not even think of the spinal cord as an organ—but the nervous system is a very complex structure. Within the brain, many different and separate regions are responsible for many different and separate functions.
Which autonomic plexus is the largest?
The solar plexus
The solar plexus is the largest autonomic plexus and provides innervation to multiple abdominal and pelvic organs. The superior mesenteric plexus includes the superior mesenteric ganglia and is located around the superior mesenteric artery.
What is autonomic tone regulated by?
The autonomic nervous system is regulated by integrated reflexes through the brainstem to the spinal cord and organs.
What is the job of the Integration Center anatomy?
The receptor senses environmental stimuli, sending the information to the integrating center. The integrating center, generally a region of the brain called the hypothalamus, signals an effector (e.g. muscles or an organ ) to respond to the stimuli.
What is the integration center of the nervous system?
The cerebrum, divided into left and right cerebral hemispheres, is the most complex integrating center in the CNS. Each hemisphere consists of gray matter or cerebral cortex, internal white matter, and a cluster of nuclei deep within the white matter, the basal nuclei or basal ganglia.
