It is the center for the eyes and ears and reticular formation is the main key here. The last section is the forebrain which contains many structures including the thalamus, hypothalamus, limbic system, and the cortex. It is responsible for more complicated ordeals that need the brain. The forebrain’s largest structure is the cerebral cortex and it is responsible for sensory functions, cognitive functions, motor functions, conscious experiences, voluntary actions, language, and intelligence. It is what you see on the outside of the brain and its actually very thin and wrinkly.
The nervous system consists of two divisions; the central nervous system and the peripheral nervous system. The central nervous system is the combination of the nerves within the skull and spine, while the peripheral nervous system is the nervous system that goes everywhere inside (autonomic nervous system) and outside (somatic nervous system) around the body except skull and spine. The somatic nervous system has two kinds of nerves; afferent nerves that carry sensory signals from the external parts of the body to center, and efferent nerves which carry motor signals from central nervous system to muscular system. The autonomic nervous system also has afferent and efferent nerves and afferent nerves carry sensory signals from internal organs
A. Theoretical Background: The nervous system is categorized into two different divisions: The central nervous system (CNS) and the peripheral nervous system (PNS). The CNS mainly consists of the brain and spinal cord. The PNS consists of the nerve impulses that carry synapses to and from the spinal cord. It includes the cranial nerves such as ganglia, enteric plexuses and sensory receptors.
The nervous system is made up of two systems that work together to help the body function. One of the systems is the Central Nervous System (CNS) which consists of the spinal cord and the brain. The other system is the Peripheral Nervous System (PNS) which is made up the nerves that connect to the rest of the body. Working together they both contribute to the wonder known as the nervous system, but how? (Better Health Channel, 2014).
But what is "brain"? Brain is an organ of the body in the head that controls functions, movements, sensations, and thoughts. Yep, brains are absolutely like remote controls! It has 3 anatomical divisions: Forebrain that contains the cerebrum, thalamus and hypothalamus, Midbrain, which is a part of the brainstem and Hindbrain that contains the pons, medulla oblongata and cerebellum. Cerebrum, cerebellum and the brainstem are considered as the three main parts of the human brain.
The CNS consists primarily of the brain, spinal cord, and contains tissues other than the nervous tissue such as small amounts of connective tissue and blood vessels (Campbell, Reece and Simon, 2004). There are two types of nervous tissue in the CNS. Grey matter is composed of neurons, synapses, blood vessels, and neuroglial cells. The neurons that constitute grey matter have copious amounts of somata and minute quantities of myelinated axons. Myelin is a fatty substance that envelops axons constructing a sheath that acts as an insulator for the electrical impulses that travel through the axon and appears as a white colour.
The nervous system is an important part of the body that controls much of what we perceive, think and do. It can be divided into central nervous system and the peripheral nervous system. The CNS consists of the brain and spine, while the peripheral nervous system consists of nerves
“The nervous system can be divided into two parts: central and peripheral. The central nervous system includes the brain and the spinal cord. The peripheral nervous system includes all the nerves and fibers outside the nervous system (Jarvis, 2014, p. 633). How is the verbal response? Is it oriented or disoriented?
Divisions of the Telencephalon The brain is divided into three parts, namely the forebrain, midbrain and the hindbrain. Telencephalon is the anterior part of the forebrain and contains the left and the right cerebral hemispheres(Freberg, 2009). The main divisions of the telencephalon are the cerebral cortex, which is made up of gray matter, the hippocampus, the amygdala, the olfactory bulb and the basal ganglia. Primary functions of each division Each division of the telencephalon has a number of functions as listed below. Cerebral Cortex This is the outer covering of the cerebral hemispheres that has a wrinkled appearance which provides enough surface area for cortical cells(Freberg, 2009).
Our nervous system helps in coordination of the activity of our muscles, constructs input from the senses, monitors the organs and initiates actions. Organs called the brain, spinal cord and nerves have the ability to control the shape of a human’s life. There perform different functions and if there will be any disorder in any of these things will go horribly wrong. So, better is to visit a neurologist twice in a month. Symptoms that commonly require a neurologist are coordination problems, a change in sensation, confusion, muscle weakness and dizziness.
