What are the functions of the cranial and facial bones?
The cranium has bones that protect the face and brain Connected to the cranial bones are facial bones that give structure to the face and a place for the facial muscles to attach. Together, the cranial and facial bones make up the complete skull. The cranium has a very important job: to hold and protect the brain.
What are the 3 facial bones?
It is our facial skeleton that supports the skin and mucous membranes. The maxilla supports the upper lip, the mandible the lower lip. The nasal bones and vomer provide attachment points for the cartilage of the septum and nose tip. The size of the zygomatic bone defines whether we have high cheekbones or not.

What are the facial bones quizlet?
The mandible bone is the largest and strongest bone of the face. It is the lower jaw bone. The Lacrimal Bones are delicate fingernail-shaped bones that form partof the medial orbit. The Zygomatic Bones are the cheekbones.
Which of these is a facial bone quizlet?
Which of the following is a facial bone? The vomer is a facial bone.
What is the function of facial bones?
The facial skeleton serves to protect the brain; house and protect the sense organs of smell, sight, and taste; and provide a frame on which the soft tissues of the face can act to facilitate eating, facial expression, breathing, and speech.
How many facial bones are there?
14 facial bones
The face skeleton includes 14 facial bones (6 paired and 2 unpaired) with specific anatomical landmarks and embryological development. These bones include the paired inferior nasal conchae, nasal bones, maxillae, palatine bones, lacrimal bones and zygomatic bones, as well as the unpaired mandible, and vomer.
What is the function of the mandible?
The mandible is the largest bone in the human skull. It holds the lower teeth in place, it assists in mastication and forms the lower jawline. The mandible is composed of the body and the ramus and is located inferior to the maxilla. The body is a horizontally curved portion that creates the lower jawline.
What is the major function of the axial skeleton?
What is the major function of the axial skeleton? Your axial skeleton provides support and cushioning for your brain, spinal cord and organs in your body. Muscles in your body that move your head, neck and trunk attach to your axial skeleton.
Which of the following is not a function of the facial bones of the skull?
The palatine processes of the maxillae form the anterior two-thirds of the hard palate. Which of the following is NOT a function of the facial bones of the skull? The cranial cavity, which does protect the brain, is not made up of facial bones.
What is the purpose of the cranial bones quizlet?
– They protect the brain. The outer surfaces of cranial bones provide large areas of attachment for muscles that move the various parts of the head.
What is the largest facial bone?
The mandible is the largest and strongest of the facial bones.
What is the function of the axial skeleton?
What is the function of mandible and maxilla?
jaw, either of a pair of bones that form the framework of the mouth of vertebrate animals, usually containing teeth and including a movable lower jaw (mandible) and fixed upper jaw (maxilla). Jaws function by moving in opposition to each other and are used for biting, chewing, and the handling of food.
What is the function of the zygomatic bone?
Definition. The zygomatic bone is a paired facial bone. Both zygoma or cheek bones are irregular and articulate with other bones of the cranium and face. They are important contributors to mastication or chewing, providing an attachment point for the masseter muscle – a jaw adductor that closes the jaw.
What is the function of the axial and appendicular skeleton?
Together, all the bones of the appendicular skeleton are responsible for making movement of our bodies possible. While the axial skeleton protects and supports the internal organs and the body as a whole, both work together to allow us to operate and function normally.
What 4 parts make up the axial skeleton?
The axial skeleton includes the bones that form the skull, laryngeal skeleton, vertebral column, and thoracic cage.
What are the 5 functions of the facial bones?
What is the function of the cranium?
Introduction. The skull (also known as cranium) consists of 22 bones which can be subdivided into 8 cranial bones and 14 facial bones. The main function of the bones of the skull along with the surrounded meninges, is to provide protection and structure.
What is the function of the facial bones?
The facial bones support the many muscles and soft tissues of the face, head, and neck. The form of your face is largely due to the shape of your facial skeleton. These multiple bones also feature foramina (holes) that allow important cranial nerves and blood supply to cross from the inside to the outside surfaces and vice versa.
What are the different types of facial bones?
Our initial pair of interior facial bones are the lacrimal bones. The lacrimal bones are the smallest bones of the face. They help form the eye orbits and, a more relatable feature, your tear ducts. The palatine bones form the roof of the mouth. They are very well hidden due to their location in the facial structure.
What is the function of the mandible bone?
Mandible Bone Anatomy. The mandible is the facial bone that forms the lower jaw and contains the lower teeth. The zygomatic bones are two facial bones that form the cheeks and the lateral walls of the orbits. The paranasal sinuses are cavities of various sizes that function to secrete mucous into the nasal cavity, lighten the skull,…
Why do we have different pairs of bones in the face?
This makes easy viewing somewhat problematic. Yet, each pairing is important for distinct reasons. Our initial pair of interior facial bones are the lacrimal bones. The lacrimal bones are the smallest bones of the face. They help form the eye orbits and, a more relatable feature, your tear ducts.
