Important Tables for Quick Revision
Types of Neurons and Their Functions
| Type of Neuron | Function |
|---|---|
| Sensory Neuron | Transmits signals from sense organs to CNS |
| Motor Neuron | Sends commands from CNS to muscles or glands |
| Interneuron | Connects sensory and motor neurons |
Parts of the Human Brain and Their Functions
| Brain Part | Function |
|---|---|
| Cerebrum | Controls voluntary actions, thinking, memory |
| Cerebellum | Maintains balance and coordination |
| Medulla Oblongata | Regulates involuntary functions like breathing |
| Hypothalamus | Controls hunger, thirst, and emotions |
| Thalamus | Acts as a relay center for sensory signals |
FAQs on Neural Control and Coordination Class 11
Q1. What is the role of neurotransmitters in neural coordination?
A: Neurotransmitters help in transmitting nerve impulses across synapses by carrying signals between neurons.
Q2. How does the brain control body functions?
A: The brain processes information and sends signals via the nervous system to control voluntary and involuntary body functions.
Q3. What are the differences between CNS and PNS?
A:
CNS (Central Nervous System): Includes the brain and spinal cord, responsible for processing and interpreting information.
PNS (Peripheral Nervous System): Comprises nerves outside the CNS, transmitting signals between CNS and the body.
Q4. Why is the spinal cord important?
A: The spinal cord transmits nerve signals between the brain and body and plays a role in reflex actions.
Q5. Where can I download Class 11 Biology handwritten notes for Chapter 21?
A: You can download the free PDF notes from the link provided in this article.
