Nervous System: The human nervous system is a communication that controls all parts of your body (communication within environment) — whether it is voluntary or involuntary. S.O.R: Stimulus Organism Response There are two parts of the nervous system: ◦ The central nervous system (CNS), made up of your brain and spinal cord (vertebrate protects spinal cord) ◦ The peripheral nervous system (PNS), made up of the nerves that carry messages to and from the CNS and other parts of you body. The CNS receives information from all over the body, processes that information, and then sends out messages telling the body how to respond. Nerve Cells: The nervous system is made up of trillions of nerve cells, or neurones, even though we don’t use …show more content…
The human brain contains about 100 billion neurones, and has an average volume of 1200-1400mL. Once brain cells die, they stay dead forever. The brain controls and regulates body functions. Without it you cannot survive. Damage to the brain is repaired slowly. Sometimes other parts of the brain take over the function of the damaged parts, but there are instances where brain damage is permanent. The Cerebrum: Associated with higher brain function, such as thought and action. The cerebrum obtains information from an individual’s surroundings and their body, and then sends that information to a specific part of the cerebrum. The cerebrum interprets this knowledge and decides what must happen next. The muscles and sensory information from the left side of the body is controlled by the right side of the brain, and vice versa. Occupies more than 80% of the brain, and contains over 10 billions neurones. The folds in the cerebrum are called ‘convolutions’, and are used to fit more neurones and information in. These folds increase its surface area by three times. It is here that the high intellectual functions of humans take place. The cerebrum controls you conscious thoughts and the intentional (voluntary) …show more content…
The cerebrum is divided into two hemispheres, each of which are specialised for certain behaviours — called the right and left cerebral hemispheres. When it comes to intended actions such as walking or hitting a ball, the right hemisphere controls the left side of your body, and the left hemisphere controls the right side of the body. The right side of the brain specialises in visual imagery and spatial abilities, whereas the left side of the brain dominates in logical abilities and language. Cerebellum and Medulla: In general, the cerebellum is responsible for controlling motor movement and muscle coordination. The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain — and regulates motor movements. The cerebellum coordinates voluntary movements including posture, balance and speech, which are factors that provide for smooth movement and activity. In addition, the cerebellum is responsible for motor learning. This means that it is responsible for learning an individual movement or action and facilitates the development of it. The brain stem is the stem-like part of the brain that connects to the spinal cord. The medulla has many basic functions, including the regulation of heart rate,
The central nervous system consists of the brain and spinal cord. The brain takes information from the senses and processes it and it also makes decision sand sends commands to the body. The spinal cord carries information to and from away the brain. The peripheral system, on the other hand, is the system that allows communication between the central nervous system with the sensory systems. It also makes it possible for the brain and spinal cord to control muscles and
The peripheral nervous system, or PNS, is the part of the nervous system responsible with carrying sensory information (a person’s senses) and motor information (a person’s coordination) to and from the central nervous system (CNS, the part that takes the information and applies it to the body), as well as throughout the whole body. Both parts of the nervous system are made up of nerve cells, or neurons, which carry the electrical impulses that contain the information sent between the PNS and CNS. The neurons
The Central nervous systems include the brain and spinal cord which transfers voluntary nerve impulse to skeletal muscles, skin, muscles, and glands.
Cerebrum: The cerebrum is the main part of the brain, which has two halves, or hemispheres. The right hemisphere controls the left side of the body and deals with things such as creativity, music, and art. While the left hemisphere of the cerebrum controls the right side of the body and is in charge of language, problem solving, and math. The cerebrum’s many tasks are carried out by its outer layer, or its cortex. This has distinct areas that have different roles. Motor areas trigger movement; sensory areas deal with the senses, while association areas clarify information.
The brain is composed of 3 main structural divisions, the cerebrum, the cerebellum and the brainstem. The cerebrum fills up most of your skull, it is divided into right and left hemispheres it is involved in remembering, problem solving, thinking, and feeling. It also controls movement. Functionally, it obtains information from your surroundings then sends that information to a specific part of the cerebrum. The cerebrum interprets the knowledge and decides what must happen next. The cerebrum, holds the instructions for everything you do in your daily life. The cerebellum sits at the back of your head, under the cerebrum. It controls coordination and balance. Most body movements require the coordination of multiple muscle groups. Times muscle
The nervous system (NS)consists of the central nervous system (CNS) and peripheral nervous (PNS.) It is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. The NS integrate all physical, emotional, and intellectual activities. These two structures
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
In the nervous system we have several systems of cells, tissues, and organs that allow the body to properly function. Meanwhile, our nervous system is divided into two systems known as the Central Nervous System (CNS) and Peripheral Nervous System (PNS).
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 “little brain,” or cerebellum, in many ways resembles a smaller version of the cerebral cortex (e.g., it contains two distinct hemispheres) and is located just behind and underneath it. The cerebellum works as an integrator, allowing us to control and process our perceptions and motor movements. Many neural pathways link the cerebellum with both the cerebral cortex and the spinal cord. The cerebellum smoothly integrates these pathways, receiving feedback about body’s position and using this information to direct our movement.
The central nervous system (CNS) is part of the human body which includes the brain and spinal cord (Lewis, Heitkemper, Dirksen, & Bucher, 2014). The cells of the nervous system are known as neurons, which is protected and nourished by neuroglia (Lewis et al., 2014). The spinal cord includes ascending and descending tracts which controls sensory and muscle movements (Lewis et al., 2015)
The central nervous system (CNS) consists of the brain and the spinal cord. The brain is the most complex of all organs and has a central role which is to control all of the bodily functions, such as awareness, movement, sensations, thoughts, speech and memory. Sensory neurons also known as are nerve cells receive information as tiny electrical signals. There are three different type of neurons that all have a different function. Sensory neurons carry messages (signals) to the spinal cord and then on to the brain, relay neurons carry messages from one part of the CNS to the other whereas the motor neurons carry messages from the CNS to effectors. For example if a person accidently touches something very hot the skin receptors would very quickly send nerve impulses to the spinal cord which would then be processed on to the brain and the
The Central nervous system consists of both, the brain and spinal cord. It merge information that it will receive and influence all activities that are part of the body. The brain is the main role of the bodily functions. Those functions consist of speech, thoughts, movements, etc. The spinal cord connect the brainstem and spinal canal. The nerve roots eventually exit both sides of the spinal cord sending messages
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.
The cortex consists of four sections, called "lobes". The frontal lobe is connected to reasoning, planning, speech, movement, emotions, and problem solving. The parietal lobe is associated with balance, recognizing, and movement. The occipital lobe is associated with vision. The temporal lobe is connected to hearing, memory, and speech. The cortex is highly wrinkled, making the brain more convenient, as this increases the brain's surface area, giving it more room for neurons. The cerebrum is divided into two hemispheres- the left hemisphere, and the right hemisphere. The right hemisphere is associated with creativity, and the left one is linked with logic. A bundle of nerve fibers, known as the corpus callosum connects these "hemispheres" (Brain Structures and their Functions). The cerebellum, which is also known as the "little brain", is similar to the cerebrum, since it also has two hemispheres and a highly folded surface. This part of the brain is linked with movement and balance. The cerebellum is assumed to be older than the cerebrum "evolutionarily" (Brain Structures and Their Functions). The brain stem controls basic life functions such as blood pressure, breathing, and heartbeat. Scientists say that the brain stem is the simplest part of the brain (Brain Structures and Their Functions).
