Bones of the Cranium
Which bone is shaped like a butterfly? What structure does it contribute to?
Sphenoid bone ; Orbits of the Eye
What is the largest facial bone that forms the lower jaw?
The Mandible
The joint that connects the mandible to the temporal bone and allows hinge-line and gliding movements.
Temporomandibular Joint
This structure is often called the curtain and consists of the soft palate and the uvula.
Velum
This three-part region connects the oral, nasal, and laryngeal cavities.
Pharyngeal Cavity
The large opening at the base of the skull that allows the spinal cord to pass through.
Foramen Magnum
What paired bones form the upper jaw and fuse at the intermaxillary suture?
The Maxillae
Flat, powerful muscle of mastication that covers the outer surface of the mandible and elevates it during chewing.
Masseter
The only intrinsic muscle of the velum, who's contraction both shortens and lifts the velum.
Uvulus
The primary function of the muscles in the pharyngeal cavity is to do what to the pharyngeal tube?
Narrowing (or Constricting)
Part of the temporal bone that forms the cheekbone and contributes to the zygomatic arch.
Zygomatic Arch
Maxillary bones
Intrinsic tongue muscle that elevates the tip of the tongue.
Superior Longitudinal Muscle
This muscle forms the bulk of the velum and, when contracted, draws the velum upward in a muscular sling.
Palatal Levator
This muscle arises from the walls of the pharynx and pulls the velum downward and backward.
Palatopharyngeus Muscle
The three sutures that connect the major bones of the cranium.
Coronal, Sagittal, and Lambdoidal Sutures
Paired bones form the lateral and inferior walls of the orbits and the cheekbone, articulating with the frontal, maxilla, and temporal bones.
Zygomatic Bones
Ring-shaped muscle surrounds the lips and allows puckering and closing of the mouth.
Contraction of this muscle, which forms the anterior faucial pillar, causes the velum to move downward and forward.
Palatoglossus Muscle
The three overlapping constrictor pharyngeal muscles.
Superior, Medial, and Inferior
What are the 8 bones of the cranium and which two are paired?
Frontal, Parietal (Paired), Occipital, Temporal (Paired), Ethmoid, Sphenoid
What are the 14 bones that make up the face and which are paired?
Maxillae (paired), Mandible (unpaired), Nasals (paired), Palatines (paired), Zygomatics (paired), Inferior Nasal Conchae (paired), and Vomer (unpaired)
Muscle that originates at the styloid process of the temporal bone and pulls the tongue upward and backward.
Styloglossus
The fibers of this muscle arise from the sphenoid cartilage, wrap around the hamulus of the pterygoid, and its contraction is responsible for opening the Eustachian tube.
Palatal Tensor
Besides its function in narrowing the pharyngeal tube, the pharyngeal muscles play a crucial role in these two processes.
