Study Notes
Brain Structure
- Folds in the brain are called gyri, and the valleys between them are called sulci.
- The brain has hollow fluid-filled cavities called ventricles.
- The third ventricle connects with the fourth ventricle through a long narrow tube called the cerebral aqueduct.
Orbit Bones
- The walls of each orbit are formed by parts of seven bones: frontal, sphenoid, zygomatic, maxillary, palatine, lacrimal, and ethmoid bones.
- The orbits are cone-shaped bony cavities that hold:
- The eyes
- The muscles that move the eyes
- Fat
- The tear-producing glands
Facial Bones
- The skeleton of the face consists of 14 bones.
- The mandible is the largest, strongest bone in the face.
Paranasal Sinuses
- The air-filled sinuses are called paranasal sinuses because they cluster around the nasal cavity.
