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
