Head and Neck
Skull and Face
- Skull: Protects the brain and supports facial structures.
- Facial bones: Include the nasal bones, maxillae, zygomatic bones, mandible, and more.
- Features: Eyes, eyebrows, eyelashes, nose, mouth, ears.
Brain and Nervous System
- The brain controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, and many more.
- The nervous system is divided into the central nervous system (brain and spinal cord) and peripheral nervous system.

Functional Systems and Their Roles
Nervous System
- Coordinates bodily functions and responses.
- Divided into central and peripheral components.
Circulatory System
- Comprises the heart, blood vessels, and blood.
- Responsible for delivering oxygen and nutrients, removing waste.
Respiratory System
- Includes lungs, trachea, bronchi, and diaphragm.
- Facilitates breathing and oxygen exchange.
Digestive System
- Breaks down food, absorbs nutrients, and expels waste.
Musculoskeletal System
- Provides support, stability, and movement.
