It consists of a lacrimal shaft, lacrimal sac and nasolacrimal duct.
Palatine bone
It forms the roof of the nose and the wall of the nasal cavity.
Vomare-bone
It is a quadrangular plate like bone. It forms the NASA interface.
Nasal Concha
A pair of thin and curved bones located on either side of the nasal cavity are the nasal concha.
Nasal bone
It is a rectangular bone. It forms the bridge of the nose.
Facial skeleton
The front and lower part of the carotid body is called the face. It consists of 14 bones in total. The facial bones are:
(i) Nasal bone: It is a rectangular bone. It forms the bridge of the nose.
(ii) Nasal Concha: A pair of thin and curved bones located on either side of the nasal cavity are the nasal concha.
(iii) Vomare: It is a quadrangular plate like bone. It forms the NASA interface.
(iv) Palatine bone: It forms the roof of the nose and the wall of the nasal cavity.
(v) Lacrimal bone: It consists of a lacrimal shaft, lacrimal sac and nasolacrimal duct.
(vi) Zygomatic bone: It is a quadrangular bone. It consists of an elevated part called the zygomatic arch.
(vii) Maxilla: The upper jaw consists of two equal maxillae. Right and left maxilla. It has four amplifiers. These are – zygomatic, palatine, frontal and alveolar.
(viii) Mandible: Mandible is the lower jaw. It looks U shaped. It consists of a trunk and 2 branches. It has two amplifiers. Coronoid and condyloid.
Sphenoid bone
Sphenoid is the bone forming the carotid floor. It looks like a bat or a butterfly. It consists of a body stem and 3 pairs of appendages. Its parts are the greater wing, the lesser wing and the pterygoid process.
Ethmoid bone
Ethmoid is a spongy bone. It forms the eye socket and nasal septum. It consists of 6 plates. 1 transverse plate, 1 vertical plate, 2 orbital plates and 2 labyrinth plates. Each labyrinth plate contains tiny air chambers.
Temporal bones
Two temporal bones exist on either side of the carotid. Each bone consists of four segments. squama, petromastoid, tympanic and styloid processes. In this bone the hearing organ, auditory canal, carotid canal and facial nerve canal are located
Occipital bone
The occipital bone surrounds the navel. It has a hole called Foramen magnum. The occipital bone consists of a shell part, 2 lateral parts and an occipital part. It connects the carotid with the atlas.
