The Central Nervous System

The nervous system is made up of 2 main parts - the spinal cord and the brain. These two parts combine to make the central nervous system and the sensory and motor nerves which form the peripheral nervous system. Neurons process information in the form of electrical signals, namely nerve impulses, which travel along the axon. Charged ions are not able to enter plasma membranes which make neurons have a difference in ion concentration between the inside and the outside of a neuron. This prevents the passive diffusion of Potassium and Sodium ions from areas of high concentration to areas of low concentration. Proteins which act as ion channels and ion pumps are attached to plasma membranes. This allows the ions to be transported across

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 hindbrain, located directly above the spinal cord, contains the medulla, pons, and cerebellum.The medulla controls breathing, heart rate, swallowing, digestion, and maintaining an up right posture. As well, the medulla is where nerves from the left brain transfer to the right and nerves from the right brain transfer to the left. Below the medulla are the pons. The pons control sleep and arousal. Behind both the medulla and the pons is the cerebellum. The cerebellum is involved in regulation and coordination of body movements and learning.

“The nervous system coordinates behavior and helps maintain the internal stability of animals” (World of Health). The brain is one part of the nervous system. It is divided into three parts: the forebrain,

The central nervous system (CNS) that is one of the main parts of the nervous system in the body which consists of the brain and spinal cord. [1] Unlike the other systems, CNS controls many jobs at the same time. Some of these functions are controlling voluntary movements such as walking and involuntary movement such as digestion. [1] “It is also the core of our thoughts, perceptions, and emotions.” [1] Unfortunately, there are many diseases that can disable CNS partially or even totally, and one of these diseases is multiple sclerosis (MS). This essay will define MS and cover the main characteristics, the symptoms, and the types that exist.

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 central nervous system (CNS) is that portion of the vertebrae nervous system that is composed of the brain and spinal cord. Together with the peripheral nervous system (PNS), the other major portion of the nervous system, the CNS coordinates the body's interaction with the environment. The CNS is contained within the dorsal cavity, with the brain in the cranial subcavity (the skull), and the spinal cord in the spinal cavity (within the vertebral column).

The forebrain is responsible for a variety of functions including receiving andprocessing sensory information, thinking, perceiving, producing and understandinglanguage, and controlling motor function. There are two major divisions of forebrain: thediencephalon and the telencephalon. The diencephalon contains structures such as thethalamus and

There are three main part of the brain. The forebrain, midbrain, and hindbrain. The forebrain is located in the anterior part of the brain in the cerebral hemisphere. It consists of the thalamus, hypothalamus, and the subthalamus. (Britannica, encyclopedia britannica, 2017) The midbrain is located in the brain stem. It is responsible in aiding with vision, hearing, and motor control. (Britannica, Midbrain, 2017) Lastly, the hindbrain. The hindbrain consists of the medulla oblongata (breathing

The central nervous system, or CNS, consists of the brain and spinal cord. The CNS is responsible for accepting information from the rest of the body through the peripheral nervous system, and responding by sending signals back out into the body. It is essential that the CNS work properly for one to function properly in day to day life. However, there are circumstances in which it is necessary for the CNS to be suppressed or excited for the wellbeing of a patient. The CNS is affected by varying types of medications including but not limited to: anesthetics, anticonvulsants,

The brainstem, midbrain, and hindbrain is located in the southern part of the brain and houses the oldest structures in terms of how the brain grew through human evolution. It is the gateway to the rest of the brain, all information passes through the brainstem. The brainstem is comprised of the cerebellum, thalamus, pons, midbrain, and the medulla oblongata. To start with the functions on the brain, the spinal cord is a bundle of closely bound nerves that connect throughout the body and form the central nervous system. It connects to the medulla oblongata, its purpose is to control involuntary functions such as breathing and heartbeat. Then the medulla connects to the pons which controls sleep, breathing, swallowing, bladder control, hearing,

The nervous system is figuratively a command center of various organisms, including humans, in which its primary role is to receive and send messages. These messages are carried by nerve cells, known as neurons. The two major components of the system are the Central Nervous System (CNS) and the Peripheral Nervous System (PNS) (Eunice Kenedy Shiver National Institute of Child Health and Human Development 2013). Previous educational research demonstrate that the CNS contains the brain and the spinal cord. The brain, one of the most important organ, is also made up of many parts, where each part has its own roles, such as the control over awareness, movements, sensations, thoughts, speech, and memory. For instance, the occipital lobe, which is

The largest part of the brain called cerebrum forms a curved around the thalamus, whereas the second largest part of the brain namely cerebellum located posteriorly to the pons at the base of skull. Moreover, the transverse fissure separates the occipital lobe of cerebrum between the cerebellum (Applegate, 2010). Not only that, the brainstem consists of midbrain, pons and medulla oblongata present inferior to the thalamus. Additionally, the superior cerebellar peduncle connects the cerebellum to the midbrain (Lazo, 2005). Next, the pituitary gland lies in the sella turcica, posterior to sella turcica is the dorsum sellae and anterior to sella turcica is the sphenoid

Central nervous system (CNS) is composed of brain and the spinal cord. Neurons constitute a major part of the developing CNS. An axon is an extension of a neuron. The brain grows as a swelling at the front (rostal) end of the neural tube and later leads to become a spinal cord (1,2). Development of the CNS involves many complex mechanisms beginning at the onset of transformation of a single layer of ectodermal cells, the neuroectoderm until the end of the differentiation process resulting into highly complex structure involving variety of neural cell types (1,2). A large number of cell types need to be arranged spatially and temporally to form a complex structure during an
