The Central Nervous System

The central nervous system (CNS) is the processing center for the nervous system. It receives information from and sends information to the peripheral nervous system. The two main organs of the CNS are the brain and spinal cord. The brain processes

First, the part of the brain that is responsible for higher forms of thought such as language, the broca’s area which pertains to the production of speech, located in the frontal lobe, is much needed for communication with my friends. When I first seen my friends it was the broca’s area that allowed me to speak smoothly and fluently to them, and as we sat around the table together eating pizza and playing cards it was this part of the brain that indorsed my friends and I to socialize as it helps everyone talk to one another. The Wernicke’s area that is affiliated with the broca’s area is the part of the brain that helps understand the meaning of words.

Q1: The cerebral cortex is a highly organized, six layered structure (L1-6) with a variety of excitatory and inhibitory cell types. Excitatory (glutamatergic) neurons make up 80% of the cortex and consist of pyramidal and spiny stellate (granule) neurons. Inhibitory (GABAergic) neurons make up only 20% of the cortex and consist of four different subtypes: non-fast spiking serotonin expressing GABAergic neurons, martinotti cells, basket cells, and chandelier cells (Petersen & Crochet, 2013; Shipp, 2007). The total number of neuronal cells in the adult human cortex is 21.4 billion for females and 26.3 billion for males; however, there are also non-neuronal cells present in the cortex (Pelvig, Pakkenberg, Stark, & Pakkenberg, 2008). The major non-neuronal cells are glial cells and consist of: oligodendrocytes (75% of non-neuronal cells), astrocytes (20%) and microglia (5%) (Pelvig et al., 2008). The layering of the cortex is highly organized, with specific cell bodies located in each layer. Layer 1 receives input from other cortical layers as well as subcortical layers and is comprised solely of inhibitory neurons, although there are axons and dendrites that project onto these neurons in addition to non-neuronal cells (Petersen & Crochet, 2013). Layers 2/3 are difficult to differentiate from one another, and often referred to as the supragranular layers. These layers contain medium sized pyramidal cells that have densely packed and highly aligned apical dendrites and make

In the organization of the Human Nervous System it is divided into sections such as the sensory system, which gathers and process information from the surrounding environment: motor systems which responds from environment by sending signals and information to facilitate movement behavioral responses and the associational system which is a meditator from most multifaceted and least problematic brain functions. Within these different functions of the nervous system it is divided into two components where these functions can happen the central nervous system that comprises of brain and spinal cord and peripheral nervous system that embodies nerves and ganglia.

In addition, the limbic system is responsible for our perception of other emotions, both positive and negative, which explains the mood altering properties of many drugs. The cerebral cortex is divided into areas that control specific functions. Different areas process information from our senses, enabling us to see, feel, hear, and taste. The front part of the cortex, the frontal cortex or forebrain, is the thinking center of the brain, it powers our ability to think, plan, solve problems, and make decisions.

Our ability to partisipate in a conversation is made possible using our temporal lobe and the broca's areas of the brain. The broca's area is responsible for our speech production, comprehending language processing these languages, and helping a person to control facial neurons. These bundles of anatomical fibers can be found in the frontal lobe of the cortex. Composed of the pars triangular and the pars operculas; two primary parts. The pars triangular can be located in the broca's area. This part of the brain is believed to help interpret multiple modes of stimulus. the broca's area is where we organize and respond to verbal conducts. The pars opercularis can be found in the broca's area of the brain; supporting only one stimulus mode. Pars opercularis assist with coordinating the organ's used for producing speech and language because it is located near the area's of the brain that are related to our motor skills.

The Broca’s area is located in the prefrontal cortex, which, as explained in our textbook, is the part that is mostly responsible for our speech and our thinking. The primary function of this region is to assist us in speaking and the forming of words. This region would be affiliated as my friends and I converse during our game night. As we exchange words and laugh and roll from one topic of conversation to the next, the Broca’s area is utilized.

Every behavior begins with biology. Our behaviors, as well as our thoughts and feelings, are produced by the actions of our brains, nerves, muscles, and glands. In this chapter we will begin our journey into the world of psychology by considering the biological makeup of the human being, including the most remarkable of human organs—the brain. We’ll consider the structure of the brain and also the methods that psychologists use to study the brain and to understand how it works.

1.What are the 2 main divisions of the nervous system and the basic structures that make

The action that is required for standing up is for the muscle to contract in the lower portion of the body from the gluteus maximum to the Gastrocnemius muscle.

The central nervous system is mainly the brain and spinal cord. These two have a very specific protective covering to build up by other soft tissues. The brain is dividing into forebrain, mid brain, and the hind brain. Most of the functional mapping for the muscular movements and the sensory approach, as well as the executive functions, is delivering throughout the fore brain into the discrete regions. The mid brain creates a part of the brainstem, which is basic keeping that person alive. The hind brain is involved in the formation of the head which is necessary to maintaining balance of the body. The spinal cord is a barred shaped of the nerve that connects to the brain. The spinal cord nerves transmit information from the body organs and

The Broca's area is a part of the brain responsible for our ability to speak and communicate. This part of the brain is also involved with language comprehension as well as hand movement. While engaging in conversation the hippocampus will be responsible for the long-term memories specifically facts and events. Memories

Central nervous system (CNS) is a system in our body that is responsible for integrating, processing and coordinating sensory data and motor commands. It consists of the brain and spinal cord. CNS may be associated with a lot of disorder. An article written by Tim Newman in Medical News Today proclaimed that the major causes of disorders that effect the CNS are trauma, infections, degeneration, structural defects, tumors, autoimmune disorders and stroke. One of the most common disorder or disease related closely to CNS is multiple sclerosis. An article in the Medline Plus updated by Joseph V. Campellone, MD, Division of Neurology,at the Cooper University Hospital, Camden, NJ and Multiple Sclerosis society of Canada agreed that multiple sclerosis

The central nervous system and the peripheral nervous system work together to collect information from within the body and from the environment outside it. The systems process all the collected information and send instructions to the body; to obtain an appropriate response. Once the data arrives, the brain will sort and file it before sending out any commands on what to do. The central system is the main command center of the body that contains the brain as well as the spinal cord. The peripheral nervous system contains a network of nerves that connect the rest of the body to the central nervous system.
