Control And Communication- Unit 2 Flashcards
Hormone produced when blood glucose concentration is low (e.g after sleeping), which activates the enzyme that promotes the conversion of glycogen back into glucose
Glucagon
Simple arrangement of three neurons that enable a nerve impulse to be transmitted from a receptor to an effector
Reflex arc
Type of nerve cell that carries nerve impulses from receptors in sensory organs to CNS
Sensory neurones
System of glands which releases hormones into the bloodstream
Endocrine system
Tiny space between two neuron’s which briefly contains a chemical during the transmission of a nerve impulse
Synapse
Target organ for insulin and storage organ for glycogen
Liver
Rapid, automatic,involuntary response to a stimulus
Reflex action
Region of the brain responsible for balance and muscular contraction
Cerebellum
Sugar molecule whose uptake and storage is controlled by hormones produced by the pancreas, used to produced ATP during respiration
Glucose
Protein molecules which act as chemical messengers, secreted into the blood by an endocrine gland
Hormones
Region of the brain for control of breathing and heart rate
Medulla
Type of nerve cell that carries impulses from a sensory neuron to a motor neuron
Inter neuron
A lifelong condition in which a person’s blood sugar can become too high due to the lack of insulin
Diabetes
Type of nerve cell that carries impulses from the CNS to muscles or gland
Motor neuron
Proteins on the surface of a cell, within target tissues, which bind to specific hormones
Receptors
Hormones produced when blood sugar concentration is high (e.g after a meal), which activates the enzyme which promotes conversion of excess glucose as glycogen
Insulin
Largest region of the brain responsible for mental processes
Cerebrum
Storage carbohydrate made from glucose, stored in the liver
Glyogen
Organs of the body which is responsible for monitoring blood glucose concentrations and releasing hormones to control blood glucose levels
Pancreas
