Organs of the Head. The Organs of the Head include: the ear, the eye, the nose and sinuses, the salivary glands, and the oral cavity. The ear can be divided in to three sections: the external ear, the middle ear, and the inner ear. The external ear functions to capture and direct sound waves through the external acoustic meatus to reach the ...

- Facial muscles. The facial muscles are the main constituents of your face, playing a significant role in facial expression. Also known as the mimetic muscles, these skeletal muscles allow you to smile, wink, frown, express fear, and so on.
- Salivary glands. Salivary glands are anatomical structures located in close vicinity to the oral cavity. They secrete saliva into the mouth to help with protection, lubrication, and digestion.
- Major arteries of the head. There are several arteries supplying the head with oxygenated blood. The most important ones for head anatomy branch from the external carotid arteries.
Nerves of the Upper Limb. The Axillary Nerve. by Vidhya Lingamanaicker. Explore detailed information on the anatomy of the human head, including bones, muscles, nerves, organs, and joints. Ideal for medical education.
The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into: the facial bones (14 bones: 2-zygomatic, 2-maxillary, 2-palatine, 2-nasal, 2-lacrimal, vomer, 2-inferior conchae, mandible).
- Skull. The skull is a strong, bony capsule that rests on the neck and encloses the brain. It consists of two major parts: the neurocranium (cranial vault) and the viscerocranium (facial skeleton).
- Nose and nasal cavity. Sticking out from the middle of your face is your nose, a structure that allows you to smell and breathe. It is composed of the nasal bones and cartilage that has two openings called nostrils.
- Eye. The nose is flanked by two anatomical structures called the eyes. Each one consists of an eyeball suspended inside a bony socket within the skull, named the orbit.
- Ear. Found on either side of the head are your ears. In fact, the only things visible are the auricle and the opening of the ear canal (external auditory canal) because the intricate anatomy is actually hidden inside your skull.
The head contains sensory organs: two eyes, two ears, a nose and tongue inside of the mouth. It also houses the brain. Together, these organs function as a processing center for the body by relaying sensory information to the brain. Humans can process information faster by having this central nerve cluster.
