Head & Neck Anatomy Flashcards
(22 cards)
What is the function of the frontal bone?
Forms the forehead
The frontal bone is shell-shaped.
What do the parietal bones form?
The roof and sides of the skull
They are a pair of flat, quadrilateral bones.
Where are the temporal bones located?
On the sides and base of the skull
They house the structures of the ears.
What structure does the occipital bone encircle?
The spinal cord
It forms the back and base of the skull.
What is the ethmoid bone’s location and function?
Located in the midline of the skull between the eyes; forms the roof of the nasal cavity
It contributes to the medial wall of the orbit and the anterior cranial fossa.
What does the sphenoid bone form?
The base of the cranium
It is located behind the eye and below the front part of the brain.
List the bony anatomy landmarks mentioned.
- Body
- Ramus
- Mandible notch
- Neck of mandible
- Angle of mandible
- Condyle
These landmarks are important for understanding the mandible’s anatomy.
What organ at risk is located behind the eye?
Optic nerve
It is crucial for vision.
What is the sella turcica?
A depression in the sphenoid bone/base of skull
It houses the pituitary gland.
What structures are located in the sella turcica?
- Pituitary
- Hypothalamus
- Optic Chiasma
These structures play essential roles in endocrine and neural functions.
What are the components of the Upper Digestive System?
- Nose
- Nasal Cavity
- Pharynx
- Larynx
These structures are involved in the intake and initial processing of food and air.
Name the structures found in the oral cavity.
- Lips
- Cheeks (Buccal Mucosa)
- Teeth (Alveoli)
- Hard Palate
- Floor of mouth
- Retro molar area
- Anterior ⅔ of Tongue
These structures are essential for digestion and speech.
What are the types of tonsils?
- Pharyngeal
- Palatine
- Lingual
Tonsils are part of the immune system and help in fighting infections.
What is the function of the parotid glands?
Produce saliva essential for oral and digestive health
There are left and right parotid glands.
What is the function of the nasopharynx?
Receives air from the nasal cavity via internal nares
It is the uppermost region of the pharynx.
What is the role of the oropharynx?
Essential for swallowing, directing food, liquid, and air
It is the middle part of the pharynx.
Where is the hypopharynx located?
Most inferior part of the pharynx, behind the larynx, above the esophagus
It directs food and liquid to the esophagus.
What is the piriform sinus?
Tear-shaped pocket in the mucosa of the laryngopharynx
It plays a role in swallowing.
What are the vocal cords a part of?
The larynx
They are essential for producing sound.
What happens at the bifurcation of the common carotid artery?
It splits into internal and external carotid arteries at the superior margin of the thyroid cartilage
This occurs approximately at the level of C4.
What is the position of the internal carotid artery?
Centrally placed between the external carotid artery and internal jugular vein
This positioning is crucial for understanding the vascular anatomy of the neck.
Which vein appears largest among the three vessels in the neck?
Internal Jugular Vein
It is key for draining blood from the brain and face.
