Intro to Axial Skeleton

Condyle

smooth and round articulated surface

Bone classification: shape

- sutural (ex: sutures) - irregular (ex: vertebra) - short (ex: carpal bones) - flat (ex: parietal bone) - long (ex: humerus) - sesamoid (ex: patella)

Articulation

a joint; the place where two bones come together

Process

a projection from a structure

Disarticulated bone

bone separated out from the other bones it normally interacts with

Bone classification: structure

compact vs. spongy

Types of sutures

coronal, sagittal, squamous, and lambdoid

vertebral column

curvatures: cervical, thoracic, lumbar, and sacrococcygeal

Ramus

elongated process/branch

Facet

flat articulated surface

Types of sinuses

frontal, maxillary, sphenoidal, and ethmoidal

Canal

hole/opening

Meatus

hole/opening

Foramen

hole/opening (foramina for small)

Sinus

hollow spaces in the skull and face bones around your nose

Composite Bone

one bone made up of multiple bones fused together

examples of composite structures

orbit, hard palate, zygomatic arch, and nasal septum

Axial skeleton consists of...

skull, hyoid bone, vertebral column, and thoracic cage (80 bones)

Suture

solidified connection between bones (cannot move)

examples of composite bones

sternal, sacrum, coxal

Composite structure

structure made up of multiple structures fused together

hyoid

the only bone of the body which does not articulate with any other bone
