Sensory System Essasy

Sensory organs: The body consist of five major sensory organs they are hearing, smell, touch, taste and sight. Sensory organs are an extension to the nervous system. Sensory organs are a system which consist of sensory cell types and are able to respond from specific occurrences from its internal and external environment. This is able to occur due to signals being sent to the central nervous system where it is interpreted. Sensory organs are essential to survival of the human race. For example hearing allows humans to assess information and if it’s a threat the body can take action. Below are the five different types of sensory organs.

The term sensation is used when referencing the process of sensing the environment through taste, touch, sound, smell, and sight (Goldstein, 2014). Moreover, it is the process that occurs once the sensory receptor experiences stimulation, which in turn produces nerve impulses that are sent to the brain to be processed in its raw form, then perception comes into play (Goldstein, 2014). Perception is used to describe the way people interpret these sensations and tries to make sense of everything around them on a daily basis. Perception is the occurrences of the brain

The primary focusing lens is the cornea, the clear window at the very front of your eye. The internal lens, called the crystalline lens, is adjustable and alters your focus from distance to near. Sometimes, one of these two lenses may have a radius of curvature that is too steep. In myopia, it is often the cornea that is too highly curved. It is this curvature which is altered in laser eye surgery. Shortening the eyeball has been tried, but it has not been without the potential of serious and permanent damage. Often in situations where the crystalline lens is forced into an excessive plus power curvature, myopia can result. This may occur from near vision stress, a

Though our sensory organs may be working fine, environmental influences may distort our interpretation of the data the organ is sending to us. For example, we could look down a street and not see anyone and think it is safe to walk down that street, but someone could be behind a tree or other object. We do not always interpret sensory data correctly no matter what sensory organ we are using. That is the most important reason we should be aware that we may not always rely on sensory information. Our senses are who we are, without them we are left to isolation and our ability to think and learn due to lack of experience. Senses are our connection from the physical world into the realm of our mind. “There is nothing in the mind unless it is first in the senses” (Kirby &

Sensory processing develops naturally and is done without effort (What is, n.d., para 2). The brain’s “ability to process and organize sensations begins to emerge in the womb and continues into adolescence” (Bolles, 2001). “The human body takes in sensory input from several different sensory systems, organizes it in the brain for functional use, and then sends out signals to the rest of the body to activate” adaptive response (An Introduction, 2014). There are eight sensory systems found in the human body (SPD, n.d, para 1). Five of the eight sensory systems are known as the

There are five common senses that are discussed and learned from an early age: sight, hearing, taste, touch, and smell. The I-function, the conscious part of the brain, is very aware of these senses. It voluntarily checks information obtained by these senses in order to experience the environment, and also when a strong enough stimuli has signaled attention to these specific receptors. There are other equally important sensory systems set up that are essential for normal body functioning, but these are not so easily recognized by the I-function because the nervous system keeps the input unconscious.

Approximately 90% of occupational therapists, who work in school settings, use interventions based on the sensory integration (SI) theory and the understanding of sensory processing to treat sensory processing disorder (SPD) (Ahn, Miller, Milberger, & McIntosh, 2004). A sensory diet is one of the interventions based on the SI theory and consists of a combination of sensorimotor activities designed to provide a child sensory stimuli for facilitating adaptive behavior. The dissertation focuses on investigating the effectiveness of a sensory diet in improving a child’s engagement in school activities.

Individuals with a sensory loss need effective positive communication in their life in order to maintain their mental wellbeing and improve their health and emotional state. It's important for the individual to feel that they can still participate and contribute in the decision making process, having choices and control in how they live their lives whilst still allowing individuals to retain their personal dignity by having informed choices in the way they are cared for and supported. This helps individuals to cope with their sensory loss and enables them to feel included which helps to build their self esteem and confidence and contributes to a better quality of life. For individuals with sensory loss ,communication is vital that in order

Jean Ayres an occupational therapist, developed the theory of sensory integration in 1960 (Smith, S., Mailloux, Z., & Erwin, B. n.d.). Jean Ayres defined sensory integration as “The neurological process that organizes sensations from one’s body and from the environment and makes it possible to use the body effectively in the environment” (Ayres,1989, p. 22). Occupational therapists are trained in adapting the environment to address such individual client needs (What Is Occupational Therapy, (n.d.). Jean Ayres believed that the various sensory systems allow us to successfully interact with the environment (Ayres, 1972, p. 1). Moreover, additional research also suggests that a child requires appropriate levels of arousal, orientation, and attention in order to interact and engage with the environment (Case-Smith & Bryan, 1999).

The actions that should be taken if there are concerns about onset of sensory loss or change in sensory status as follows.

It also provides protection and support for other tissues. The fourth system is the nervous system. This system directs immediate responses to stimuli, usually by coordinating the activities or other organ systems. This organ system also provides and interprets sensory information about internal and external conditions. Now we are at the fifth system.

Sensory receptors detect when a hot spoon touches your skin which is caused by the sensory input. Once the receptors feel the input the nervous system decides what to do about it; this is integration. Motor output is what is done about the input, whether you scream or jerk away from the hot spoon. So the response that you get from the integration is the motor output when is acts upon the body.
