Bipolar neurons are commonly ________.
A
found in sensory organs such as the retina of the eye
B
involved in forming the blood-brain barrier
C
the most abundant type of neuron in the central nervous system
D
responsible for generating action potentials in skeletal muscles
Verified step by step guidance1
Understand the structure and function of bipolar neurons: Bipolar neurons are a type of neuron with two extensions—one dendrite and one axon. They are specialized for transmitting sensory information.
Recall where bipolar neurons are typically found: Bipolar neurons are commonly located in sensory organs, such as the retina of the eye, where they play a role in transmitting visual information.
Eliminate incorrect options: Bipolar neurons are not involved in forming the blood-brain barrier, as this is primarily the role of astrocytes. They are also not the most abundant type of neuron in the central nervous system; multipolar neurons hold that distinction. Additionally, bipolar neurons are not responsible for generating action potentials in skeletal muscles; motor neurons perform that function.
Match the correct function and location: Based on the information above, bipolar neurons are most commonly associated with sensory organs like the retina, where they help process sensory input.
Select the correct answer: The correct choice is 'found in sensory organs such as the retina of the eye,' as it aligns with the known role and location of bipolar neurons.
