What are the bones of the cranial skull?
Parietal (2)
Temporal (2)
Frontal (1)
Occipital (1)
How are the skull bones connected?
Fused with cranial sutures
What are the bones of the skull designed for?
Maximum protection of the brain
What are the bones of the face (facial)?
Frontal
Zygomatic (2)
Nasal
Maxillary
Temporal (2)
Mandible
Lacrimal (2)
Ethmoid
Sphenoid (2)
What joint is part of the facial area?
Temperomandibular (TMJ)
What do structures of the facial area provide?
Provides the structure of the face
What is the zygoma?
Cheek bone
What is the Supra orbital ridge?
What bones make up the eye orbit?
Frontal
Zygomatic
Maxillary
What creates the nasal bridge?
The meeting of the nasal, frontal, and maxillary bones
What makes up the floor of the nasal cavity?
The hard palate anteriorly and the soft palate posteriorly
What is the nasal septum?
It divides the nasal cavity into R/L chambers
What is the middle third of the face and what does it do?
Maxillary bone which supports nose and nasal passages
What is the ethmoid bone and its purpose?
It is behind the lacrimal bone in the eye socket and it helps direct air from nostrils to nasal cavity to lungs
What is the nasal cartilage?
Cartilage on the end of the nose that provides some structure but also allows it air to go in and out with breathing
What are the nasal conchae?
Ridges and flaps in the nose tissue that increases the surface area and helps warm and humidify air as it enters
What anatomy makes up the throat?
Larynx
- thyroid cartilage
- cricoid cartilage
Trachea
Hyoid bone
Others- pharynx and esophagus
What is the larynx and what does it do?
-Voice box
- Helps us breathe & protects against food getting in the trachea while breathing
What is the thyroid cartilage also called?
Adam’s apple
What is the thyroid cartilage?
A protective shield around the anterior larynx
What is the cricoid cartilage?
It forms the back of the voice box & completely encircles trachea
It helps keep the airway open
What is the trachea and what does it do?
- Windpipe
- regulates & allows air in/out of lungs, prevents foreign objects from respiratory system
What is the hyoid bone?
It is a floating bone suspended from the temporal bones by stylohyoid ligaments
It supports the tongue, larynx, & epiglottis and plays a role in speaking, breathing, & swallowing
What is the peristalsis epiglottis?
A flap of cartilage that prevents food and liquid from entering the lungs
