The head is the uppermost part of the human body, containing essential structures that are vital for various functions. It houses the brain, which is the control center of the body, and includes the eyes, ears, nose, and mouth, which are integral to the senses of sight, hearing, smell, and taste, respectively. Additionally, the head contains numerous muscles, nerves, blood vessels, and bones, all working together to support critical activities and overall health.

The neck is the part of the body that connects the head to the torso. It's a narrow and flexible column of bones, muscles, nerves, and blood vessels that support the weight of the head and allow for its movement. It plays a vital role in supporting the head, facilitating movement, housing essential structures, and contributing to various bodily functions. Its health and proper function are crucial for overall well-being and quality of life.

Early signs of head and neck illnesses encompass a range of symptoms that should not be ignored. These include persistent headaches, neck pain, difficulty swallowing, voice changes, vision or hearing disturbances, swelling or lumps, nosebleeds, facial pain or numbness, and skin changes. These symptoms could indicate various conditions such as infections, nerve problems, or even serious issues like tumors.
