How The Skin is Involved with the Nervous System The skin is the outside covering of the body tissue‚ which protects inner cells and organs from the outside environment. The skin is the largest organ of the body and its cells are continuously replaced as they are lost to normal wear and tear. The skin has between 12 to 20 square feet in area and accounts for 12% of body weight. It is composed of 3 layers the epidermis‚ the dermis‚ and the sub cutis. The thickness of

Session 9: The Nervous System - Assignment #2 PhysioEx Assignment : Exercise 3 Neurophysiology of Nerve Impulses Activity 1: The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Increasing the extracellular K+ causes the membrane potential to change to a less negative value because when K+ ions diffuse out across the membrane they are leaving behind a net negative charge. 2. Explain

Asthma: Disease of the respiratory system Breathing‚ the act of inhaling and exhaling of air. Oddly enough this process is an absolute necessity for life and yet we do not control it. There are two systems involved in our ability to breathe one is the parasympathetic nervous system and the other is the respiratory system. The parasympathetic nervous system controls the body ’s unconscious actions that are necessary to live such as the beating of the heart. The Respiratory system mainly consists

brain has many jobs. It controls our spinal cord‚ our central nervous system and our nervous system. The spinal cord carries messages to the brain and also to the nerve cells that carry messages from the brain. Your body senses everything. Like something smashing your toe. You react to it. It all sends itself to the brain and it reacts. The cerebrum‚ controls thinking. The nerve cells carry information from all central nervous system. Like certain areas‚ such as the 5 senses. Sensory receptors

skeleton is often described as a solid‚ moveable framework that supports the body. Bone is a strong and rigid form of connective tissue. It also works as levers and anchor plates to allow movement to take place. Bones also work for alternative body systems for example the blood cells develop in their fatty inner tissue (red marrow). The body draws from mineral stores in bones during crucial times of shortage‚ for instance when calcium is needed for healthy nerve functioning. The skeletons key components
