Study Notes

Head and Neck Orientation

The head and neck are connected to the rest of the body and include both visceral and non-visceral spaces.
Visceral spaces house organs, like the pharynx.
Non-visceral spaces house structural components, like the skull.

Anatomy of the Pharynx

The pharynx is a critical part of the head and neck because it connects these visceral spaces together.
Pharynx is vital for both breathing and swallowing processes.

Fascia in the Head and Neck

Fascia are sheets of connective tissue that organize the structural components of the head and neck.

Cranial Nerves

Cranial Nerves are a major focus in understanding the anatomy of the head and neck.
There are 12 pairs of cranial nerves, each responsible for specific functions like sensory input, motor output, and autonomic control.
