Background research
The central nervous system and the peripheral nervous system comprise the entirety of the body's nervous system, which regulates and maintains its most basic functions.
The Central nervous system is made up of the brain and spinal cord. To process information.
The Peripheral Nervous System is used for all the sensory and motor neurons of the body. To control actions of our body. Sensory Neurons collect sensory input and send it to the brain and Motor neurons transmit signals to responsive tissues.
The general role of our sense organs are used for every-day activities.
Sight
Hearing
Taste
Smell and
Touch.
Sense organs take in sensory information that gets sent to the brain, and the body acts on these messages. The eye is
The nervous system controls both voluntary action (like conscious movement) and involuntary actions (like breathing) and sends signals to different parts of the body. The central nervous system includes the brain, spinal cord, sensory organs, and all of the nerves that connect these organs to the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts. The brain and spinal cord form the control center, also known as the central nervous system, where information is
The human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from CNS, to transmit information to your limbs and organs for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain.
The central nervous system is covered in bone to protect the brain and the spinal cord which are both necessary for most functions in the body. The brain is necessary for thought processes and is the beginning of any body movement and interprets signals from the peripheral nervous system. The spinal cord allows those signals to reach the
The nervous system is a network of cells that take messages from the brain and spinal cord to other parts of the body. The nervous system is made up of the Central Nervous System and the Peripheral Nervous System. The Central Nervous System has two main parts; the brain and the spinal cord. While the Peripheral Nervous System has the Somatic and the Autonomic Nervous systems included within it.
The Nervous System can be divided into two different categories, the central nervous system (CNS), and the peripheral nervous system (PNS). The CNS is made up of the brain and spinal cord, and the PNS is made up of the rest of the nerves that connect the brain and spinal cord to the rest of the body. The major functions of the nervous system are sensory, integrative and motor function. The sensory function of the nervous system receives sensory receptors by detecting changes inside and outside of the body. The integrative function processes the information. Motor nerves convey information from the CNS to the body, and make the necessary response (Herlihy & Macbius, 2000).
The brain is the control center of the human body. It sends and receives millions of signals every second, day and night, in the form of hormones, nerve impulses, and chemical messengers. This exchange of information makes us move, eat, sleep, and think.
We use our ears for the hearing sense, and we use our eyes for vision.
Sensation refers to the process of sensing what is around us in our environment by using our five senses, which are touching, smell, taste, sound and sight. Sensation occurs when one or more of the various sense organs received a stimulus. By receiving the stimulus, it will cause a mental or physical response. It starts in the sensory receptor, which are specialized cells that convert the stimulus to an electric impulse which makes it ready for the brain to use this information and this is the passive process. After this process, the perception comes into play of the active process. Perception is the process that selects the information, organize it and interpret that information.
Visual perception and visual sensation are both interactive processes, although there is a significant difference between the two processes. Sensation is defined as the stimulation of sense organs Visual sensation is a physiological process which means that it is the same for everyone. We absorb energy such as electro magnetic energy (light) or sound waves by sensory organs such as eyes. This energy is then transduced into electro chemical energy by the cones and rods (receptor cells) in the retina. There are four main stages of sensation. Sensation involves detection of stimuli incoming from the surrounding world, registering of the stimulus by the receptor cells, transduction or changing of the stimulus energy to an electric nerve impulse, and then finally the transmission of that electrical impulse into the brain. Our brain then perceives what the information is. Hence perception is defined as the selection, organisation and interpretation of that sensory input.
The brain and spinal cord make up the central nervous system. The brain doesn't just control your organs, but also can think and remember. That part of the brain is called the mind.
The nervous system’s main function is to coordinate all of the activities in the body. The main organs are the cerebellum, which controls and coordinates movement. The cerebrum, is the center for conscious thought, learning, and memory. The last main organ is the brain stem. The brain stem keeps the automatic systems in your body working. Problems of the nervous system include, epilepsy, Alzheimer’s, and multiple sclerosis. You can care for your nervous system by wearing a seatbelt, wearing a helmet, and by not using drugs or alcohol. Something very confusing about the nervous system is that the left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body!
The PNS has two parts: the somatic nervous system and the autonomic nervous system. The somatic nervous system, or voluntary nervous system, enables humans to react consciously to environmental changes. It includes 31 pairs of spinal nerves and 12 pairs of
One sub-system under the sensory system is the visual system; the main sense organs of this are the eyes. The eye is the sensory organ that allows us to detect light from external stimuli. When a light ray is detected, the eye converts these rays into electrical signals that can be sent to the brain in order to process the information and giv...
The nervous system is primarily separated into the central nervous system and the peripheral nervous system. The central nervous system is composed of the brain, its nerve cranial and the spinal cord. The peripheral nervous system is made up of the spinal nerves that extent from the spinal cord and the autonomous nervous system separated from the sympathetic and parasympathetic nervous systems. Next would be the structure of the brain. The brain is designed by two different cells. The neurons and glial cells, otherwise known as neuroglia or glia. The neurons objective is to send and bring in nerve impulses and signals. Glial cells are non-neuronal cells that give support and nutritional value, maintains homeostasis, creates myelin and facilitates
The Eye is the organ of sight. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight, or vision, is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. When someone looks at an object, what he/she is really seeing is the light that the object reflects, or gives off.
