1. NERVOUS
SYSTEM

2. The nervous system is a
complex network of nerve
cells (neurons) and nerve
fibers that transmit and
process information.-
Importance: Controls and
coordinates body functions,
enables communication and
response to stimuli.

3. Structure of the Nervous System
•-Central Nervous System (CNS): Brain and
spinal cord-Peripheral Nervous System
(PNS): Nerves and ganglia

4. Functions of the Nervous
System
•-Sensory Function: Receives and
interprets sensory information
(e.g., touch, temperature, pain)-
Motor Function: Controls
voluntary movements (e.g.,
walking, writing)-Integrative
Function: Processes information,
enables thought, emotion, and
behavior

5. Types of Neurons
•-Sensory Neurons: Transmit
sensory information-Motor
Neurons: Transmit motor signals-
Interneurons: Integrate and
process information

6. Neurotransmitters and
Synapses
•-Neurotransmitters: Chemical
messengers (e.g., dopamine,
serotonin)-Synapses: Gaps
between neurons where
chemical signals are transmitted-
Diagram: Show synaptic
transmission

7. Nervous System
Disorders
•-Stroke: Damage to brain tissue
due to lack of blood supply-
Parkinson’s disease:
Degeneration of dopamine-
producing neurons-Multiple
sclerosis: Damage to myelin
sheath in CNS-Alzheimer’s
disease: Degeneration of neurons
and synapses
