References: NCERT Biology Class 11 Chapter 22: Neural Control and Coordination.

• Neurons and its different classification based on structures and function including their structure, dendrites, axons, synapse.
• Central Nervous System (CNS) consists of the brain and spinal cord, their locations of neurons.
• Peripheral Nervous System (PNS) is divided into what are somatic and autonomic division and their detailed explanation as described in NCERT Chapter 22 along with examples.
