(1) The medulla oblongata which lies on top of the spinal cord and contains many of the centers that control involuntary process like breathing, blood pressure and heart beat. At every level the spinal cord also serves as a reflex center possibly involving a variable numbers of inter neurons. Most of the spinal cord consists of ascending track conducting sensory impulse towards the brain and descending track carrying impulses down ward to motor neurons within the spinal cord. This (electrical) impulse, which travels from the dendrite tip to the cell body, and then along the axon to its end of the axon, sets off the release of some chemicals. Bioinorganic Systems Coordination compounds play important roles in nature. In plants, coordination is due to the result of a chemical system, wherein plant hormones or phytohormones have a major role. Copyright © 2020 Desktop Class. Start studying Biology: Coordination. In animals co-ordination is produced by two systems. The stimuli of light are received by eyes; the stimuli of smell are received by nose, so on and so forth. In multicellular organisms, following the general principles of body organization, some specialized tissues are used to provide the control and coordination activities. Hormones, adrenaline. The organs producing particular responses are known as effectors organs, which are muscles and glands. Like that in human brain is main part which perform all part and coordination in the human body. All these attributes of physiology can be achieved when the body works as one unit, in which its different organs and systems cooperate and work in harmony with each other, i.e. The five … There are 31 pairs of spinal nerves arising from the spinal cord. Auxins, gibberellins, cytokinins and are responsible for harmonious growth of plants.

Coordination and control - The nervous system The nervous system enables humans to react to their surroundings and to coordinate their behaviour. The midbrain lies between the hindbrain and forebrain and connects the two. its various functions are coordinated. Resting above the hypothalamus is the thalamus which provides connections between many parts of brain and between sensory system and cerebrum. The control and coordination of all the organs of an organism are done by the central nervous system of the body. Coordination in PlantsPlants do not have a nervous system or an endocrinesystem. All Rights Reserved. Coordination is brought about through various elements of nervous system: receptors, sensory neurons, brain and spinal cord, motor neurons and effectors. When brain gives command, muscle moves – it happens because muscle cells have special proteins that change both their (muscle’s) shape and arrangement in the cell in response to nervous electrical impulses. its diverse functions are coordinated. The messages of the type of response are passed via motor neurons or nerves to the particular effectors which produce a specific response. The brain is categorized into three major parts or regions, namely the fore-brain, mid-brain, and hind-brain. Responses to stimuli in plants are coordinated byhormones.Hormones act as chemical messengers which enableplants to respond to many factors, such as light, gravity,water, and temperature.Cells inside the plant detect stimuli, which are processedand analyzed slowly. The general nervous pathway We have various sense organs in our body. The human nervous system. This is a highly specialized cell which contains the typical organelles found in most eukaryotic cells. Animals co-ordination is produced by the two systems. Fatty substances covering the axon is the myelin sheath along with short regions of exposed axon are called nodes of Ranvier. The animal body has two levels of coordination: nervous coordination (see Chapter 29) and chemical coordination. Coordination is the working together of the various organs of an organism in a systematic manner so as to produce a proper response to the stimuli. Then we will learn how & why living beings reproduce (unit 2). As for example the sound waves are received by ears. The later by secreting hormones which are poured into blood and transported to the special organs or target organs which produce the response. Start studying Biology: Coordination. Reflex action is an automatic nervous reaction that cannot be consciously controlled and reflex arc is the nervous pathway which carries the impulses causing a reflex action. Each hemisphere is divided into four major lobes. It also brings harmony in carrying out the different tasks and activities to achieve the organization’s objectives efficiently. Coordination is controlled by regions of the brain that deal with specific functions, such as locomotion and breathing, and is carried out by the nervous system. Sleep may be influenced by thalamus centre along with the midbrain and hindbrain. The former sending message about the action or response to be made by particular organs. It is completely enclosed by the vertebrae of the vertebral column just as the brain is enclosed by the bones of the skull.
