Homeostasis
The Temperature set point for the human body
36.8 (37) degrees
The electrochemical impulse sent along neurons
Action potential
Signaling molecule transported in the blood stream
Hormone
How does sweat work?
Evaporation
What animal exists solely on Eucaliptus leaves?
Koala
A cyclic process where responses reduce disturbances to restore homeostasis
Negative feedback
Neuron that transmits a signal from receptor to control centre
Sensory neuron
A gland that secretes hormones
Endocrine gland
The widening of blood vessels
Vasodilation
Echidna or Platypus
Structures that detects or receives a stimulus, and sends a signal to a processing centre
Receptors
Neuron that transmits a signal from the control centre to an effector
Motor neuron
Cells found in endocrine glands that make and release hormones
Secretory cells
The constricting of blood vessels
Vasoconstriction
What Australian animal has cubed poo?
Wombat
An organ, cell or protein that acts on the response sent by the processing centre
Effector
What Neuron goes between the sensory and motor neurons
The Interneuron
When there is too much hormone, a target cell starts to produce less receptors, which decreases its sensitivity to the hormone.
Downregulation
Structure that reduces heat transfer
insulation
What's the tallest bird in Australia?
Emu
What does your body do to maintain Homeostasis when its hot?
Sweat, Hairs lie down, vasodilation (blood vessels dilate)
The end of the axon terminal where an action potential is passed to the next neuron
Synapse
What hormone releases sugar into the blood?
Glucagon
Removal of excess body heat through the evaporation of water.
Evaporative heat loss
Which animal (besides humans) is responsible to for the most deaths in Australia yearly?
Horses (77 deaths)
