Somatic Nervous System

Sensation and Perception are somethings we use every day in our lives. Sensation is described as using information outside of our bodies, to bring them in, and into the brain. Its a process. Sensory organs, then sensory receptors convert the smell to neural impulses and then bring them from the

The sensory system is a part of the nervous system. It is responsible for processing our sensory information, and it is the way in which we make contact in our everyday lives through our five senses – sight, touch, hearing, smell and taste. (IML Training, 2012) Our sensory receptors allow us to pick up information – ears, eyes, nostrils, tongue and skin. All senses evolve to collect their distinct type of information about our environment and to inform us of our status within it. (Goldstein, 2009)

The peripheral nervous system made up of sensory and motor neurons that transmit messages to and from the central nervous system. The main functions connect to the CNS as well. The PNS is not protected by the bone of the spine and the skull. Which leaves it’s open to the exposed of toxins and mechanical injuries. The PNS is divided into two man parts, which are the somatic and autonomic nervous system. The somatic nervous system is there to transmit messages through the body. It transmits messages to the CNS like sight, sound, smell, temperature and body positions. When the message is transmitted to the CNS, that’s how a human is able to raise a hand, walk, wink or even run. The somatic system is even able to make a human keep its

A person’s perception of his or her surroundings is a result of the five senses touch, sight, smell, sound, and taste. These senses are what determine what is existent and what is non-existent.

The five senses of the human body are vision, audition, olfaction, gustation, and somatosensory. Vision is the sense dealing with sight. Vision is most sensitive to light. The main part of our vision comes through our eyes and is processed through our brain. Audition is the sense of hearing. Audition is obtained through our ears picking up vibrations and processing the sounds we hear. Olfaction is the sense of smelling. Olfaction occurs through our olfactory receptor neurons being stimulated by a certain chemical in the air and being sent to our brain to process what we smell. Gustation is the sense of tasting. Gustation involves our tongue and the taste buds on that which have receptor cells in them. The final sense is the somatosensory

The two systems within the peripheral nervous system are somatic nervous system and the central nervous system. The control that somatic nervous system have is the process of reflex arcs and optional muscular systems. The peripheral nerve sends sensory information that predict skeletal muscles to the motor nerve and central nervous.

Autonomic nervous system (ANS) regulates the functions of internal organs automatically unconsciously. The motor part of the ANS is

The nervous system coordinates voluntary and involuntary actions of animal bodies and is in charge of transmitting signal from one part of the body to another part. It is divided into two main systems, the Central Nervous System (CNS) that contains the brain and the spinal cord, and the Peripheral Nervous System (PNS) that includes mostly all nerves connecting the CNS to every part of the body (Martini et al., 2005). The entire nervous system relies on the good functioning of specialized cells: the neurons that convey electrical signals; and the neuroglia that is composed of several types of specialized cells with different functions either involved in the structure of the nervous system, the enhancement of the signal transmission or even in the defense mechanism.

Many people are fortunate enough to have five senses. These senses are taste, touch, sight, smell, and hearing. Some people don 't have sight and are blind, and others don 't have hearing and they are deaf. Not many people go through their lives without a sense of feeling, taste, or smell; not having those senses are much less common than being deaf or blind.

The nervous system is critical for human survival. The human nervous system is responsible for signaling bodily functions, sensory experiences, and information processing. The nervous system consists of three major structures: the brain, the spinal cord, and the peripheral nervous system (Brodal 1-18). The brain, spinal cord, and peripheral nerves are responsible for different processes and have unique structures. The brain is divided into three substructures: the cerebrum, cerebellum, and brain stem (Nieuwenhuys, and et al). The spinal cord is a bundle of nervous tissue that extends from the brain; the spinal cord and brain together compose the central nervous system (CNS). The peripheral nervous system are the nerves that are outside of the CNS, and are responsible for connecting the CNS to organs and the limbs of the human body (Brodal 1-18). Although each structure is unique, they all consist of nerve cells called neurons, which are considered the building blocks of the nervous system and are composed of dendrites and a single axon (Gartner and Hiatt 186-218). The structure of the neuron empowers the nervous system to interpret all incoming information, such as a smell, pain, or taste, and is responsible for sending critical nerve information that initiates such functions as breathing and heart rate, all of which are essential to human vitality.

The organs of our body are controlled by many systems in order to function correctly and efficiently in order to survive within the environment we live in. These include the heart, stomach and intestines and other vital organs and body systems. All of the systems in our body are regulated by a part of the nervous system called the autonomic nervous system (ANS). The ANS is part of the peripheral nervous system and it controls many organs and muscles within the body. Rather bizarrely we are unable to determine or feel its presence in our bodies as it is working involuntary, as a reflexive manner. A common example of this involuntary action is best understood when

A neuron consists of a cell body, axon and dendrites. The cell body has a neuron, which is the control centre that controls and regulates the activities of the neuron. The dendrites are extending in a branch formation, projecting out from the cell body, which receives nerve impulses. The nerves travels down the axon until it reaches the synapse, which are the gap between two neurons. The nerve impulse must be converted into a neurotransmitter to be received by the other neuron triggering an electrical impulse.

Examples include eyes, nose and skin. The eyes are the main sensory organs being tested in this experiment. Eyes allow us to detect visible light which is reflected on images and allows us to see them. (McMillan 35)
