​Which of the following is NOT part of a neuron? ​

Correct option is B

​The correct answer is (b) Cone.

A neuron is the fundamental unit of the nervous system that transmits signals throughout the body. Its structure includes the following main parts:

• Dendrite: Receives signals from other neurons or sensory receptors.
• Cell Body (Soma): Contains the nucleus and organelles, responsible for maintaining the neuron's functions.
• Axon: Transmits signals away from the cell body to other neurons or effector cells.

Cone, on the other hand, is not a part of a neuron. It refers to photoreceptor cells in the retina responsible for color vision.

Explanation of Other Options:

• Dendrite: It collects incoming signals and transmits them toward the cell body.
• Cell body: Also called the soma, it integrates signals and supports the neuron's metabolic activities.
• Axon: A long projection that carries electrical impulses away from the cell body to other neurons or target tissues.

Information Booster:

• Neurons communicate via electrical signals (action potentials) and chemical messengers (neurotransmitters).
• Types of neurons: Sensory neurons, motor neurons, and interneurons.
