Chapter 12: Coordination and Response in Humans
What you need to learn in this chapter
In this chapter, we will learn about coordination and response in humans. We will understand the sequence and components involved in human coordination, such as stimulus, receptor, integration centre, effector, and response. We will also identify and describe both external and internal stimuli. Next, we will study the nervous system and explain the structures of the human nervous system, including the central nervous system (brain and spinal cord) and the peripheral nervous system (sensory receptor, cranial nerve, and spinal nerve). We will also learn about the functions of different parts of the central nervous system related to coordination and response, such as the cerebrum, cerebellum, medulla oblongata, hypothalamus, and pituitary gland. Moving on, we will explore neurones and synapses by drawing and label the structures of a sensory neurone and a motor neurone, including dendrites, axons, cell bodies, myelin sheaths, and nodes of Ranvier. We will analyze the functions of each type of neurone in impulse transmission. Lastly, we will compare and contrast voluntary and involuntary actions. We will describe reflex actions involving two neurones and three neurones. By the end of this chapter, we will have a solid understanding of coordination and response in humans, the nervous system, neurones and synapses, and voluntary and involuntary actions.
