Total questions: 15
Worksheet time: 14mins
Homeostasis is defined as:
The process of maintaining a stable internal environment
The process of maintaining a stable environment
Keeping your temperature at a set point
Receptors sensing changes in your body
What is a receptor?
Receptors are located in the skin
Receptors carry messages to the hypothalamus
A receptor receives messages and causes a response
Receptors or sensors detect changes in the body
When CO2 levels become too high in our blood, we begin to breathe faster. In this example, our diaphragm and intercostal muscles are
the stimuli
the response
the effectors
the neurons
The nucleus of a neuron is found in the
synapse
myelin sheath
dendrite
cell body
Impulses only travel in one direction in a neuron. What direction do they travel?
From the dendrite to the axon terminals
From the axon terminals to the dendrite
From the cell body to the dendrite
From the axon to the myelin sheath
What way do impulses travel across synapses?
From axon terminal to dendrite
From dendrite to axon terminal
What do sensory neurons do?
Transmit impulses from sense receptors to motor neurons
Transmit impulses from sense receptors to the brain and spinal cord
Transmit impulses from the brain and spinal cord to effectors
Transmit impulses from muscles to the brain
What do motor neurons do?
Transmit impulses from the receptors to the brain and spinal cord
Transmit impulses from brain and spinal cord to muscles
Transmit impulses from the effector cells to the sensory neurons
Transmit impulses from the brain and the spinal cord to the effector cells
A bundle of axons is called a
Neuron
Nerve
Synapses
Nerve cell
Look at the picture. In this scenario: name the stimulus, the receptor, the effector and the response.
Stimulus = fire
Receptor = hand
Effector = skin
Response = move hand away.
Stimulus = hot pan
Receptor = skin
Effector = muscles in arm and hand
Response = move hand away
Stimulus = fire
Receptor = fingers
Effector = muscles in arm and hand
Response = move hand away
Stimulus = hot pan
Receptor = skin
Effector = muscles in arm and hand
Response = clench hand tighter
