Study Notes
Orbital Structure
- The floor of the orbit is formed by the maxilla bone.
- The optic foramen is located posteromedially and contains the optic nerve and ophthalmic artery.
Orbital Walls
- The medial wall of the orbit is formed by the lacrimal bone and the frontal process of the maxilla bone.
Eye Components
- The sclera of the eye is covered by the conjunctiva.
Lacrimal System
- The fossa for the lacrimal sac is located in the medial wall of the orbit and contains the lacrimal sac.
Joint Types
- Synarthroses are joints that permit little movement.
- Fibrous synarthroses are joints where the bones are joined by fibrous tissue.
- An example of cartilaginous synarthroses is the joint between the ribs and the sternum.
- Diarthroses are joints that permit a wide range of movement.
- Bony fusion articulation is a type of joint where the bones are fused together, resulting in the loss of movement.
