B1 Coordination and Control
25
nervous : Central .............. System
impulse : Electrical signal carried along the neurons
stimuli : Change in the environment detected by sensory receptors
receptor : Special sensory cell which detects changes in the environment
neuron : Basic cell of the nervous system
central : The .......................... Nervous System
effector : Organs which respond to impulses from the nervous system
secrete : To release chemicals such as hormones or enzymes
motor : Type of neuron which carries impulses from the CNS to effector organs
reflex : Rapid automatic response of the nervous system that does not involve conscious thought
synapse : Gap between neurons where the transmission of information is chemical rather than electrical
menstrual : Reproductive cycle in women controlled by hormones
ovulation : Release of mature eggs from the ovary
period : Stage in the menstrual cycle when the womb lining is lost
pituitary : Gland in the brain which produces a range of hormones controlling body functions
oestrogen : Female sex hormone which stimulates the lining of the womb to build up
progesterone : Female sex hormone used in the contraceptive pill
homeostasis : Maintenance of constant internal body conditions
urine : Liquid produced by the kidneys containing urea, excess water and salts
kidneys : Organ which filters the blood to remove urea, excess salts and water
enzyme : Protein molecule which acts as a biological catalyst
pancreas : Organ that produces insulin and many digestive enzymes
photsynthesis : Process where plants make food using carbon dioxide, water and light energy
phototropism : Response of a plant to light
auxin : Plant hormone that controls responses to light and to gravity
gravitropism : Response of a plant to the force of gravity
