What’s New, THE NATURAL COMPUTER OF THE BODY, by: Divine Jean Dela Cruz Manandeg, , Breathing, sleeping, reading, thinking, and feeling, All these activities and processes keep you going, Have you ever wondered what system does everything?, It’s the nervous system, essential and crucial to our well-being, The nervous system is a collection of neurons that transmit signal, CNS involves the brain and spinal cord, it’s central, PNS is about all nerves outside the CNS, it’s peripheral, The system detects changes, both internal and external, Chemical means of communication can be too slow for the body, Speedy reactions or responses for survival are necessary, The key is electrical responses, all fast and quick, Sending signals along neurons even before you think and speak, Stimulus is a change in the environment, detected by a receptor, Response is a change in the organism, right after a stimulus detector, All changes needed to be analyzed for survival, Instantaneous transmission of impulses are electrical, Removing your hand after you got pricked, why is that?, Flinging your hand away after holding a pot, is it hot?, All these examples are normal stimuli reactions, Our brain is like a computer, it controls all body functions, , Question:, What is the message of the poem?, _________________________________________________________________________________, _________________________________________________________________________________, _________________________________________________________________________________, , 5, , CO_Q3_Science 10_Module 3

What is It, Nervous System: The control system of the body, , The nervous system is a, complex network of nerves and, cells that carry messages to and, from the brain and spinal cord to, various parts of the body. It is, considered as the body’s storage, center of information and also, the body’s control system. It is, mainly, responsible, for, controlling and coordinating all, the organ systems by sending, messages, from, the, brain, through nerve signals. It makes, sure that all the parts of the, body are working together, efficiently., , Figure 2. Nervous System, Illustrated by: Queenie Joy V. Alcantara &, Louella C. Zacarias, , Major Divisions and Parts of the Nervous System, I. Central Nervous System (CNS) serves as the main processing center of the nervous, system. It consists of two main components, namely;, A. Brain is an organ located within the skull that functions as organizer and, distributor of information for the body. It has three main parts:, 1. Cerebrum is the large, upper, part of the brain that controls, activity and thought., 2. Cerebellum is the part under, the cerebrum that, controls posture,, balance, and coordination., 3. Brain stem connects the brain, to the spinal cord and controls, automatic functions such as, breathing, digestion, heart, rate, and blood pressure., , Figure 3: Parts of Brain, , Figure 3. Parts of the brain, Illustrated by: Queenie Joy V. Alcantara &, Louella C. Zacarias, , 6, , CO_Q3_Science 10_Module 3

B. Spinal cord serves as a channel for signal between the brain and the majority, of the body parts, and controls some simple musculoskeletal reflexes even, without the processing of the brain., II. Peripheral Nervous System (PNS) connects the central nervous system to the, organs and limbs. It has two main divisions:, A. Somatic Nervous System is associated with the voluntary control of body, movements and has two main parts:, 1. Spinal Nerves carry motor and sensory signals between the spinal, cord and the body., 2. Cranial Nerves are nerve fibers that carry information into and out, of the brain stem., B. Autonomic Nervous System is associated with the involuntary control of body, movements and has two subdivisions:, 1. Sympathetic Nervous System is activated when the body is in a, dynamic role or stress. (e.g., increased heart rate and breathing,, dilation of pupil, sweating), 2. Parasympathetic Nervous System maintains body functions and, restores the body to normal or relaxed mode., , The Nerve Cell, The nerve cell is the basic, unit of the nervous system and it is, also called as neuron. There are, billions of neurons in the body., Figure 4 shows the structure of a, nerve cell. A neuron has a cell, body containing the nucleus. In the, cell body there are root-like, structures called the dendrites, and, axons., Dendrites, carry, impulses toward the cell body while, axons carry impulses away from, the cell body. The gap between, neurons is called synapse., , Figure 4: The parts of a neuron, , Figure 5: Synapse between 2, neurons, Illustrated by: Queenie Joy V. Alcantara &, Louella C.

How Nervous System coordinates and regulates feedback mechanisms to, maintain homeostasis?, The nervous system provides quick responses in maintaining homeostasis., Homeostasis is maintained in the body by regulating the body temperature, blood, pressure, pH, and glucose concentration., The nervous system and endocrine system are working together to maintain, body’s homeostasis. Homeostasis is the state reached when each part of the body, functions in equilibrium with other parts. This is attained through the regulation of, the bodily functions by the endocrine and nervous systems., Feedback mechanisms are used by most of body systems to maintain, homeostasis. When the brain receives messages from the body about an internal, change in one of its systems, it works to restore the system to its normal state. The, hypothalamus affects the pituitary gland, also known as the master gland, to secrete, the right hormones. The hormones will flow with the blood and reach the specific, organs to restore the normal state of the body or homeostasis. Molecules of hormones, are received by receptors of cells making this event a neuroendocrine coordination., The nerves that are found all over the body allows the nervous system to monitor, homeostasis of the body. While the endocrine system helps by secreting hormones, into the bloodstream and send them to specific organs. The levels of hormones in the, body are controlled by feedback. It is important that the amount of hormones in our, body is kept at the right level. To achieve homeostasis, the nervous and endocrine, systems work with each other to maintain a normal range of many processes and, substances in the body such as:, • Temperature of the body, • Amount of water in the body, • Amount of metabolic wastes in the cell, • Blood calcium level, , 8, , CO_Q3_Science 10_Module 3

When a body system, leaves a set point and falls outside its, (20), range, signals are sent, through the nervous system which trigger, (21), to bring the system, back into the normal range of functioning. This process maintains, homeostasis. For example, thermoreceptors and mechanoreceptors in the, skin sense changes in, (22), and pressure, respectively. Then,, signals sent from them to the, (23), make it possible to detect, situations that could cause injury or death.
