What is a dendrite?
It is the part of a neuron that carries information to the cell body.
It is the part of the neuron that carries information away from the cell body.
It is a cell that sends signals to the body to move.
It is a cell that sends signals to the central nervous system based on sensory input.
It is the part of a neuron that carries information to the cell body.
What is the term for changes in the internal or external environment that cause a response?
messages
signals
stimuli
nerves
The term for changes in the internal or external environment that cause a response is stimuli.
How do signals from sensory neurons reach motor neurons?
Through interneurons in the brain and spinal cord that connect sensory neurons and motor neurons
Signals from sensory neurons do not get sent to motor neurons
Motor neurons signal for the body to move the signal toward them
Signals move from dendrite to dendrite towards motor neurons
Through interneurons in the brain and spinal cord that connect sensory neurons and motor neurons.
What part of the nervous system is completely protected by bone?
peripheral nervous system
sensory neurons
central nervous system
interneurons
The central nervous system is completely protected by bone.
you see a mosquito land on your hand and swat at it. A signal passes through many parts of different neurons to make this happen. Which component of the nervous system is the last to be involved in this process?
axons in sensory neurons
dendrites in sensory neurons
axons in motor neurons
dendrites in motor neurons
The component of the nervous system that is the last to be involved in this process is the axons in motor neurons.
Which sensory receptors are involved in hearing?
photoreceptors
thermoreceptors
mechanoreceptors
chemoreceptors
Mechanoreceptors are involved in hearing.
A person who has the condition CIPA is unable to feel pain or temperature. Which sensory receptors are affected by this condition?
thermoreceptors and mechanoreceptors
mechanoreceptors and chemoreceptors
chemoreceptors and photoreceptors
photoreceptors and thermoreceptors
Thermoreceptors and mechanoreceptors are affected by the condition CIPA (Congenital Insensitivity to Pain with Anhidrosis).
Which observation could you make based on stimuli to your photoreceptors?
This apple is cold.
This apple is lightweight.
This apple is red.
This apple is tart.
The observation that could be made based on stimuli to your photoreceptors is "This apple is red." Photoreceptors are responsible for detecting light and colors, so they would provide information about the color of the apple.
How do sensory receptors communicate a stimulus to the brain?
muscle cells
corpuscles
pressure waves
electrical signals
Sensory receptors communicate a stimulus to the brain through electrical signals. When a sensory receptor detects a stimulus, it generates an electrical signal called an action potential, which travels along neurons towards the brain, allowing the brain to interpret and process the sensory information.
Which sensory receptors detect when your shoes are too tight?
mechanoreceptors
thermoreceptors
photoreceptors
chemoreceptors
