Proprioception Essay -- Biology Essays Research Papers

Proprioception How and Why at that place are five mutual senses that are discussed and l spikened from an early age sight, hearing, taste, touch, and smell. The I-function, the conscious part of the brain, is really aware of these senses. It voluntarily checks information obtained by these senses in order to stimulate 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 consistence functioning, but these are non so easily recognized by the I-function because the nervous system prevents the stimulus unconscious. One overlooked sense, known as proprioception, is as important, if not more(prenominal) important as the other senses, for normal functioning. Proprioception is the process by which the body can vary muscle contraction in immediate retort to incoming information regarding external forces, by utilizing stretch receptors in the mus cles to keep track of the junction position in the body (1). Proprioception and kinesthesia, the sensation of joint motion and acceleration, are the sensory feedback mechanisms for motor control and posture. Theses mechanisms along with the vestibular system, a fluid filled network within the inner ear that can feel the pull of gravity and helps the body keep oriented and balanced, are unconsciously utilized by the brain to provide a constant influx of sensory information (2). The brain can hence send out immediate and unconscious adjustments to the muscles and joints in order to strive movement and balance. Why has the nervous system developed the sense of proprioception, and why is it an unconscious aspect of the sensory system? Proprioception, also often referred to as the s... ...tion seems to be one of the most complicated aspects of the brain. Was the I-function one of the last aspects to educate in the human brain thus far? If so was it because the necessities for extra ct were accomplished by the species, proprioception allows movement and eating is instinctual to the brain? Why did developing cause the human to develop the I-function?
