What is homeostasis? - Correct Answer--The process of maintaining a stable
internal environment
Why is homeostasis important? - Correct Answer--Because it is essential for the
survival of cells
What does the control system do? - Correct Answer--Keeps the conditions in your
body steady
What happens in the blood glucose level is too high? - Correct Answer--the control
system decreases the level
What happens in the blood glucose level is too low? - Correct Answer--the control
system increases the level
What does the nervous system mean? - Correct Answer--that humans react to
their surroundings and coordinate their behaviour
What does the Central Nervous System (CNS) consist of? - Correct Answer--brain
and spinal cord
What is the CNS connected to? - Correct Answer--the body by sensory neurones
and motor neutrons
,What is do Sensory Neurones do? - Correct Answer--They carry information as
electrical impulses from the receptor to the CNS
What do Motor Neutrons do? - Correct Answer--They carry electrical impulses
from the CNS to effectors
What are Receptors? - Correct Answer--Cells that detect stimuli
Give an example of a receptor - Correct Answer--Receptors in the ear detect
sound
What do Effectors responded to? - Correct Answer--Electrical impulses and bring
about to a change
Give 2 examples of effectors - Correct Answer--Muscles and glands.
What is the process of CNS? - Correct Answer--Stimulus -> Receptor -> Sensory
Neurone -> CNS -> Motor Neurone -> Effector -> Response
What is a Synapse? - Correct Answer--it is where two neurones join together
What are Reflexes? - Correct Answer--an automatic responses to prevent injury
What are hormones? - Correct Answer--Chemical messengers sent in the blood
, What is another name for the Pituitary Gland? - Correct Answer--Master Gland
What does the Pituitary Gland produce? - Correct Answer--many hormones that
regulate body conditions
What do Ovaries produce? - Correct Answer--oestrogen
What is oestrogen involved in? - Correct Answer--Menstrual cycle
What do the testes produce? - Correct Answer--testosterone
What do the testes control? - Correct Answer--puberty and sperm production in
men
What does the thyroid produce? - Correct Answer--Thyroxine
What is Thyroxine involved in? - Correct Answer--Rate of metabolism
heart rate
temperature
What does the Adrenal Gland produce? - Correct Answer--Adrenaline
