of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. The regulation of breathing is the result of a complex interaction involving a system of sensors‚ a respiratory control center‚ and an effector system to carry out its commands

Assignment 3 Written Essay Questions 1. a) We are able to experience different types of sensations because our nervous system encodes messages. German physiologist Johannes Muller in his doctrine of specific nerve energies described a kind of code which is anatomical. In his doctrine‚ Muller explains that different sensory modalities exist because signals received by the sense organs stimulate different nerve pathways that lead to different areas of the brain. For example‚ when the ear

pathways between emotional centres of the brain and the vestibular (balance) system. The purpose of this literature review is to provide a background to our new technique‚ Electrovestibulography‚ which measures signals from the vestibular system. Studies identifying links between the vestibular system and emotion processing systems supports our research aims‚ which are to explore biomarkers derived from the vestibular system that can help differentiate and monitor different neuropsychiatric disorders

neurotransmitter with their receptors cause’s vasoconstriction and beta adrenergic receptors increases the heart rate and show vasodilation. (Davidyan‚ 2017) The parasympathetic nervous system decreases the blood pressure as well as heart rate through vagus nerve. The diameter of the blood vessels is regulated by the vasomotor system. Vasomotor nerves made up of sympathetic motor nerves transmit impulses to the vasomotor center to innervate smooth muscles in arteries which maintain a vasomotor tone to bring

The Nervous System and Aging Sensory changes can influence the way we see‚ hear‚ taste‚ smell‚ and respond to touch and pain. This in turn affects how we experience the world and react to things. A significant sensory change can rob us of many simple pleasures and complicate the tasks of daily living. It may mean reduced mobility‚ increased dependence on others‚ inaccurate perception of the environment‚ reduced ability to communicate and socialize‚ or loss of self-esteem. Sensory changes vary
