The Main Functions of the Nervous System and Its Role in Maintaining Homeostasis

Extract

[...] The nervous system Question 1 The structural and functional organization of the nervous system In each of the following situations, one of the elements related to the functioning of the nervous system is unable to perform its function. Using the knowledge acquired in this course and the appropriate vocabulary, indicate, for each of the cases mentioned: - The or the structures concerned ; - The cause of the problem mentioned. Paralysis and insensitivity of the right side of the body with persistence of the medullary reflex activity. [...]

[...] Locomotion is initiated by the motor control center of the brain. It is therefore naturally influenced by various ascending and descending components of the neuro-muscular and mechanical systems. The information in the form of electrical signals is transmitted within the spinal column. However, the human body moves in such a way that one cannot neglect the influence that its environment has on it. Question 4 The Integrative Function of the Brain The mother of one of your friends serves you a pot-au-feu. [...]

[...] In fact, light is the necessary stimulus for the production of the nerve impulse in question. Question 2 Nerve cell, grey matter and white matter The neurons are specialized in the transmission of the nerve impulse between the various parts of the body. In a well-structured, coherent and written in your own words text: - Describe in detail the structure of a typical neuron; - Indicate the role of each part of this neuron as you go along. A section through the brain or spinal cord shows that certain regions are grayish (gray matter), while others are a bright white (white matter). [...]

[...] This is the reaction to the stimulus. These tears are what we call emotional tears because they are caused by an emotion. Question 5 The great nerve pathways You check the temperature of the bath water of a child by dipping the fingers of your left hand into it. In a coherent and well-structured text using appropriate vocabulary and knowledge acquired in your course, including those resulting from observation and analysis of the human body, describe the main functions of the nervous system and its role in maintaining homeostasis.In a coherent and well-structured text using the appropriate vocabulary and knowledge acquired in your course, including those resulting from the observation of diagrams, describe the path of the nerve impulse on the nerve pathway used. [...]

[...] Conversely, when an individual touches the water in the bath with their hand to measure its temperature, signals are sent in the opposite direction, from the skin to the hypothalamus, and the latter sends signals again in response to this stimulus. It is the peripheral nervous system that comes into play here. The PNS is the network of nerves found outside the central nervous system. Its role is to transmit messages between the CNS and the rest of the body. [...]
