Nervous Tissue - The nervous system includes all nervous tissue in the body -Neural tissue contains two types of cells: 1) neurons (10% of all neurons‚ conduct nerve impulses) 2) neuroglia (support neurons) -We have 100 billion neurons -Organs of the nervous system: brain‚ spinal cord‚ sensory receptors of sense organs (eyes‚ ears‚ etc.)‚ and nerves (connects the nervous system with other systems‚ bundle of neurons that relay information) -Functions of the nervous system: 1) sensory input- everything
Premium Nervous system Neuron Axon
he nervous system is the communication network of the body. It consists of a complex collection of nerves and specialized cells‚ called neurons‚ that transmit messages across the different parts of the body in order for it to function and react correctly. They are known as the building blocks of the nervous system. Structurally they have long extensions that extend out from the cell body. There are two types of these extensions; dendrites‚ which are extensions of the neurons that receive signals

The Lymphatic System And Immunity The cells‚ tissues‚ and organs of the lymphatic system play a central role in the body’s defenses against a variety of pathogens‚ or disease-causing organisms. Acts against environment hazards‚ various pathogens‚ and internal threats. Lymphocytes (primary cell) are vital to or overcoming infection and disease. Lymphocytes respond to invading pathogens‚ abnormal body cells‚ and foreign proteins. They act to eliminate these threats or render them harmless

Homeostasis is defined as the adjustments a body makes to maintain an environment conducive to life. All of the organ systems in the human body must maintain a steady internal environment for the body to function properly. The factors that need to be controlled are water and salt content‚ PH balance‚ oxygen‚ sugar‚ protein‚ body temperature‚ and blood and glucose concentration. The basic principle of homeostasis is when there is an abnormal internal condition‚ it will be detected and a variation

The muscular system is what is responsible for the way that we move. Without the muscular system‚ we wouldn’t be able to participate in the normal activities that we do today. There are 700 known/named muscles that are attached to the human skeleton. There are three different types of muscle that can be found in the human body. The Visceral muscle which can be found inside organs such as the stomach. This type of muscle is controlled by the unconcious part of the brain. This muscle is also known
