tolerance limits - Represents the minimum and maximum amounts of a given factor that an individual organism can tolerate before survival is compromised, body temperature - A measure of how well your body can make and get rid of heat, blood glucose - The amount of glucose in your blood, stimulus - A change in a factor in the environment that can be detected by a sensory receptor, response - A reaction to a stimulus, stimulus-response model - A model which allows living organisms to respond to changes in their environment and act accordingly, sensory receptor - Detects a stimulus, effector - The structure in the body which causes the response in the stimulus response model, homeostasis - Processes that control and maintain a stable internal environment of an organism to compensate for changes in the internal and/or external environment, internal environment - The internal life-sustaining fluid that allows sustaining exchanges and encompassing the cells, negative feedback - A response to a stimulus that negates the stimulus or has the opposite response, nervous system - A complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body, endocrine system - The collection of glands that produce hormones, central nervous system (CNS) - A part of the nervous system, consists of the brain and spinal cord, peripheral nervous system (PNS) - Consists of all neurons that exist outside the brain and spinal cord, sensory neuron - A nerve cell that receives a message from the sensory receptor and sends it to an interneuron, interneuron - Found in the central nervous system, receives a message from a sensory neuron and sends it to a motor neuron, motor neuron - Receives a message from the an interneuron and transmits to muscle cells or glands (effectors), hormone - A group of chemicals released by endocrine glands; can be proteins, peptides or lipid derivatives and are transported from the site of production through the blood to the target site, pancreas - Receptor that controls glucose levels in the blood, Insulin - Hormone that stimulates the removal of glucose from the blood., Glucagon - The hormone that instructs the liver to return glucose to the blood, Alpha cells - Site of glucagon production., Beta cells - Site of insulin production, Type 1 diabetes - A disease resulting from the destruction of beta cells in the pancreas., Hyperglycemia - Occurs when the level of glucose in the blood is too high., Hypoglycemia - Occurs when the level of glucose in the blood is too low., Set point - The ideal condition for a factor within the body,
