If you think of the brain as a central computer that controls all the functions of your body‚ then the nervous system is like a network that relays messages back and forth from it to different parts of the body. It does this via the spinal cord‚ which runs from the brain down through the back and contains threadlike nerves that branch out to every organ and body part. When a message comes into the brain from anywhere in the body‚ the brain tells the body how to react. For example‚ if you accidentally

The Nervous System By: Brooklynne Harris Scenario A loud crashing sound causes everyone in the room to quickly turn their heads toward the source of the noise. Describe the path of the signal through the human nervous system from initial stimulus of sound to the response of turning the head. Crash and then turn of the head The Journey The loud sound that the person heard is the stimulus. In order to hear a sound‚ sound waves have to be generated and sent to the cochlea in the inner ear.

Page 1 of 5 The Brain and the Nervous System The human brain and the nervous system are essential for human life. They run the autonomic and conscious processes of the body. All of the body organs and processes independent that not conscious of are controlled by the brain. Being one of the most important of the body when issues there must be immediate solutions or the entire body will shut down. The brain is fragile and has huge functions in the body so it must be taken care of‚ but if not

Lab IX: Nervous System Histology and Spinal Cord Part II: Neurons and nerve struture 1.) There are three types of neurons. The first is the multipolar‚ which is the most common‚ and they are found as motor neurons and interneurons throughout the central nervous system. The second type of neuron is the unipolar neuron‚ which are also called psuedounipolar neurons. They are found as spinal and cranial sensory neurons. The last neuron is the bipolar neuron. They are only found in olfactory‚ visual

role of energy in the body The three systems in our body that work together are cardiovascular‚ respiratory and digestive systems which supply energy to the cells of the body. I will be describing their role of energy in the body system; also I am going to explain the physiology of the three named body systems in relation to energy metabolism. Respiratory System The respiratory system consists of tissues and organs in our body which are formed into groups. The system includes airways‚ lungs‚ blood vessels

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

AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. Anatomy: The branch of science concerned with the bodily structure of humans‚ animals‚ and other organisms‚ esp. as revealed by dissection. Physiology: The branch of biology that deals with the normal functions of living organisms and their parts. Anatomy and physiology are connected in the way
