Your nervous system is made up of: Mother calls the child by their name. The temporal lobe taps into other roles as well, such as visual memory, your ability to learn language, and emotion association. The autonomic system is the part of the peripheral nervous system that is responsible for regulating involuntary body functions, such as heartbeat, blood flow, breathing, and digestion. The nervous system, just like every other structure and makeup of our bodies, is very ordered and systematic. A glial cell is one of a variety of cells that provide a framework of tissue that supports the neurons and their activities. This is what allows the parasympathetic to slow down the heart rate, regulate digestion, and relax muscles. The two divisions of the nervous system are the central nervous system (CNS) and the peripheral nervous system (PNS). The brain and spinal cord make up your central nervous system. The primary motor cortex initiates electrical signals and impulses that initiate body movement. The central nervous system (CNS) functions as the processing center for the nervous system. First, we will take a look at the central nervous system, and what exactly that includes. ", The trigeminal nerve allows for us to experience feeling in the face, and the facial nerve allows for us to actually make facial expressions. And lastly, the autonomic nervous system contains the sympathetic nervous system (which controls our “fight or flight” response), and the parasympathetic nervous system which controls our “rest and digest” response). Unable to find your location. The vestibulocochlear nerve permits sound to proceed from our ears into our brain. }. The neuron is the more functionally important of the two, in terms of the communicative function of the nervous system. Now, the midbrain is called the midbrain, because it sits between the forebrain and the hindbrain; but it’s important to note that out of the three parts of the brain stem it is not located in the middle. The nervous system is made up of the brain, the nerves, and the spinal cord. The central nervous system is composed of the brain and the spinal cord. } It is a system of sensory neurons, motor neurons, and interneurons that extends from the esophagus to the rectum.

Your temporal lobes are located near your ears, and they mainly function in auditory processing. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. Together, these organs are in charge of control of the body and communication within various organs. These two components encompass several other components. the membranes that surround the cns iv.) { You actually have two temporal lobes, one for both hemispheres. Cluster headache is a rare but extremely painful neurological disorder, causing headache attacks that occur in cyclical bouts. We just covered a lot of information. The nervous system is involved in some way in nearly every body function. involuntary part of the nervous system ii.) The sensory nervous system is the portion responsible for detecting, relaying, and processing sensory information. The nervous system can be divided into subdivisions based on structure and on function. For example, the eyes are one of the most important sensory organs. Ganglia refers to a cluster of neuron somas (or cell bodies). The spinal cord is the other component that makes up the central nervous system. Sensations are a standard function because they record changes in homeostasis or stimulus.
