Plastic Properties, Types, and Manufacturing
Properties of Plastics
Lightweight
This provides comfort when loading and transporting objects or plastic containers.
Impermeable
We can produce fabrics that protect us from the rain, or pipes that carry water or gas.
Photodegradable
Continued exposure to sunlight degrades them and makes them more brittle over time.
Electrical Insulator
We can protect ourselves from electrical accidents if we isolate steel cables with plastic.
Tough (Not So Fragile)
We can manufacture windows, bottles, or lenses for impact-

The Neuron: The Building Block of the Nervous System
A neuron is the fundamental cell of nervous tissue.
Neuron Components:
- Cell Body (Soma): Located around the nucleus, containing most of the cytoplasm. It generates nerve impulses.
- Dendrites: Short, branching extensions that receive nerve impulses from other neurons.
- Axon: A long, slender extension that transmits nerve impulses away from the cell body to other neurons or effector cells.
Types of Neurons:
- Sensory Neurons: Transmit nerve impulses from sensory
