Answer:
The orbit is the socket or cavity of the skull in which the eye and its appendages are located. This bony socket is made up of 7 different bones. The seven bones are as follows-
Frontal bone
: the bone located in front of the skull in that forms eye socket.
Zygomatic bone
: it is cheekbone which articulates with the maxilla, sphenoid bone, and frontal bone.
Maxillary bone
: The 2 maxillary bones are joined together at the intermaxillary suture, creating the anterior nasal spine.
Sphenoid bone
: is an unpaired bone of the neurocranium.
Ethmoid bone
: is a bone in the skull that distinguishes the nasal cavity and the brain. It is situated at the roof of the nasal cavity.
Palatine bone
: These are 2 irregular bones of the nasal cavity.
Lacrimal bone: a small bone forming part of the eye socket.

Pyridostigmine works by slowing the breakdown of acetylcholine when it is released from nerve endings. Pyridostigmine is the most commonly prescribed anticholinesterase.
What is Myasthenia gravis?
- Myasthenia gravis is a condition where your muscles become easily tired and weak. There is a fault in the way nerve messages are passed from your nerves to your muscles.
- As a consequence, your muscles are not stimulated properly, so do not tighten (contract) well.
- The muscles around the eyes are commonly affected first. Myasthenia gravis is an autoimmune disease. This means that the fault is due to a problem with your immune system.
- Your immune system (which normally protects your body from infections) mistakenly attacks itself.
- Your brain normally sends messages down nerves to the muscles it wants to contract. The nerve endings then release a chemical called acetylcholine.
- Acetylcholine quickly attaches to small areas on your muscles, called receptors, and this triggers your muscles to contract. In most people with myasthenia gravis, the immune system blocks or damages these acetylcholine receptors.
- The acetylcholine cannot then attach to the receptor and so the muscle is less able to tighten.
- Pyridostigmine works by slowing the breakdown of acetylcholine when it is released from nerve endings.
- This means that there is more acetylcholine available to attach to the muscle receptors, and this improves the strength of your muscles.
- Pyridostigmine is the most commonly prescribed anticholinesterase.
