The brain is protected by three meninges: pia mater, dura mater, and arachnoid mater.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Central Nervous System - Spinal Cord Reflex Action and Reflex Arc
The pons contains fiber tracts that connect different parts of the brain and transmit signals between the brain and spinal cord.

Cerebrospinal fluid (CSF) protects the brain, transports nutrients, and acts as a shock absorber but does not generate nerve impulses.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Central Nervous System - Spinal Cord Reflex Action and Reflex Arc
Neurotransmitters can be excitatory (e.g., glutamate) or inhibitory (e.g., GABA), depending on the receptor they bind to.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Central Nervous System - Spinal Cord Reflex Action and Reflex Arc
The brain acts as the control center for coordination, processing sensory inputs and generating motor responses.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Central Nervous System - Spinal Cord Reflex Action and Reflex Arc
The spinal cord acts as a communication link between the peripheral nervous system and the brain while also mediating reflexes.

The cerebrum contains both gray matter and white matter. The gray matter, which forms the cerebral cortex, is involved in processing information.

Acetylcholine is the neurotransmitter that triggers muscle contraction at the neuromuscular junction.

The autonomic nervous system regulates involuntary functions such as digestion, respiration, and heart rate.

The medulla oblongata connects the brain and spinal cord and controls involuntary functions such as breathing and heart rate.

Higher cognitive functions are controlled by the cerebrum, not the medulla oblongata.
