Define osmosis and its role
Osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.

- Blood Cell Formation
- Storage of inorganic materials
Name the Functions of the muscular system (hint:4)
- Movement of the body

- Role in other body parts
The nervous system is divided into what 2 systems?
- The central nervous system:
- Brain and spinal cord
- The Peripheral Nervous System:
- Nerves throughout the body

- Synanthropic- immovable joint
- Amphiarthrotic- slightly movable vertebrae
- Diarthrotic- movable joint
What is Epidermolysis bullosa?
Epidermolysis bullosa is a group of rare diseases that cause the skin to be fragile and to blister easily. Tears, sores, and blisters in the skin happen when something rubs or bumps the skin.

-Loose connective tissue
- Adipose tissue
- Fibrous connective tissue
- Cartilage
- Bone tissue
- Blood tissue
-Diaphysis- shaft of the bone
-Articular Cartilage- cartilage covering entire bone
- Periosteum- membrane covering the entire bone
- Medulla- within diaphysis, contains bone marrow
Define Hypertrophy, Atrophy, and Dystrophy
Hypertrophy- muscle enlarges
Atrophy- muscles become small and weak due to disuse
Dystrophy- a disorder causing muscle weakness and leads to reduce mobility

What is the sliding filament theory?
The theory of how muscle contracts. The contraction of a muscle occurs as the thin filaments slide past the thick filaments.
