Head and Neck Anatomy Flashcards
The human skull is divided into two sections
- The Cranium
- The Face
8 Bones and covers and protects the brain
Cranium
Forms the prominence of the cheek and the lateral wall and floor of the orbit
Zygomatic Bone
Also known as Malar bones
Form the upper jaw and the hard palate
Maxillary bones
is the only bone that does not articulate with other bone
Hyoid bone
Forms the lower jaw; the only movable bone in the skull; longest strongest
Mandible
Has two separate types of movement
Temporomandibular joint (TMJ)
Gliding movement that allows the lower jaw to move forward and backward
second phase of the TMJ
The temporomandibular joint is made up of
The Glenoid Fossa
Articular eminence
Condyloid Process
The TMJ works with
four pairs of muscles of mastication to make all the movements of the mandible possible
Symptoms of limitations of movement, and joint sounds such as clicking, popping, and pain
Temporomandibular disorder (TMD)
Can be easily palpated
Sternocleidomastoid
Trapezius
The major salivary glands that are located just below and in front of the ear are
The Parotid salivary glands
The blood supply for the face and mouth comes from the
External Carotid Artery
Supplies the blood for the mandibular teeth
the inferior alveolar artery branch
is divided into three main divisions, are the primary source of innervation for the oral cavity
Trigeminal Nerve
There are____________________ connected to the brain
12 pairs of cranial nerves
The anterior superior alveolar nerve innervates the
Maxillary central
Lateral
Canine teeth
Include the inguinal, axillary, and cervical sites
lymph node sites
Produce mucus, make the bones of the skull light, and provide resonance to help produce sound
Paranasal Sinuses
