Zygomaticus Group

The large opening in the base of the skull where the spinal cord exits is called the

______________________________.

foramen magnum

Based on their anatomy, the sutures of the skull are a type of ______________________________

joint. The two sutures that follow body planes are the ______________________________ and

______________________________ sutures. Based on their degree of movements, these joints are

______________________________.

fibrous, coronal, sagittal, synarthrotic

The ______________________________ foramen is a feature of the skull because it cannot be

viewed on any individual bone in isolation.

jugular

A depression or relatively deep pit in a bone is called a(n) ______________________________

fossa

The ______________________________ of the temporal bone and the

______________________________ of the zygomatic bone join together to form the

______________________________.

zygomatic process, temporal process, zygomatic arch

he joint between a tooth and its bony socket is specifically called a

______________________________ joint. When classified by its degree of movement, this joint is

______________________________. When classified by its anatomy, this is a

______________________________ joint.

gomphosis, synarthrotic, fibrous

Raising a body part is called ______________________________ while lowering a body part is

called ______________________________. Both of these movements are possible at the

temporomandibular joint.

elevation, depression

Fetal and infant skulls have a membranous region called a(n) ______________________________

between certain cranial bones.

fontanel

When classifying bones by shape, all bones of the face are ______________________________

irregular

A “catch-all” term for a prominent projection on a bone is a(n)

______________________________.

process

A(n) ______________________________ is an opening in a bone that serves as a passageway for

blood vessels, nerves, and/or ligaments.

foramen

A feature of a bone described as a structure given off from another larger structure is a(n)

______________________________.

ramus

Moving a part of the body forward is called ______________________________ while moving a

part of the body backward is called ______________________________. Both of these movements

are possible at the joint between the mandibular condyle and the mandibular fossa.

protraction, retraction

An interlocking line of union between bones is called a(n) ______________________________.

The two that join the parietal, temporal, and occipital bones are the

______________________________ and the ______________________________

suture, lambdoidal, squamous

Based on their shape, all the bones of the cranium are classified as

______________________________ bones.

flat

The joint between the mandible and temporal bone is specifically called a(n)

______________________________ joint. When classified by its degree of movement, this joint is

______________________________. When classified by its anatomy, this is a

______________________________ joint.

modified hinge, diarthrotic, synovial

The bones in all fibrous joints are held together by ______________________________ tissue.

dense fibrous

A(n) ______________________________is a rounded process of a bone located at an articulation

site.

condyle

he ______________________________ bone, which does not form a joint with any other bone,

supports the tongue and is an attachment point for muscles involved in swallowing.

hyoid

The mandibular fossa and mandibular condyle are covered with a thin layer of

______________________________ cartilage. This forms the articular cartilage typical of synovial

joints and helps to minimize friction.

hyaline

Buccinator

Compresses cheeks inward as when blowing air out, retracts corner of mouth

Epicranius (occipitofrontalis)

Elevates eyebrows (as when surprised)

Masseter

Elevates and protracts mandible

Orbicularis Oculi

Closes eye (as in blinking or squinting)

Orbicularis oris

Draws lips together (as in kissing)
