What is homeostasis? - answer The maintenance of a constant internal environment. What is a stimulus? - answer A change in your environment than requires a response. e.g Light, sound, touch, pressure, pain, chemical or temperature. What do the receptors do? - answer Detect the stimulus or change in environment. What happens after the receptors? - answer Receptors send messages to the CNS via the sensory neurone. What makes up the central nervous system? - answer The brain or spinal cord ...

AQA A Level Biology - Topic 6 - Survival And Response What is a stimulus? A change in the environment of an organism What is a tactic response? What is a kinetic response? Directional movement in response to a stimulus Non directional random movement in response to a stimulus What is a positive and negative taxis? Positive taxis- organism moves towards stimulus Negative taxis - organism moves away from stimulus What Are receptors? different types What are effec...

negative tropisms - Answer-growth away from a stimulus Define homeostasis - Answer-Homeostasis is the regulation of internal conditions in the body. It is necessary to maintain optimal conditions for body functioning. These internal conditions can change as a result of processes within the body and as external conditions change. systems responsible for homeostasis - Answer-the nervous system - uses electrical impulses to communicate the endocrine system - uses chemical molecules to commun...

Medical oedema - ANS Medical term for fluid retention Sinusitis - ANS Sinus Infection Hyper-keratosis - ANS Excessive formation of Keratin Styes - ANS Inflamed swelling on the edge of an eyelid, caused by bacterial infection of the gland at the base of an eyelash. Neuralgia - ANS Connective tissue which supports neurones; does not transmit nerve impulses
