Anatomy-Skull Sutures

The suture that is intermediate to the temporal and parietal bones

squamous

Two bones are separated by the frontonasal suture

frontal and nasal

Which bone is the mastoid process part of?

temporal

which bone makes up the posterior a part of the hard palate

palatine

Which bone makes up the upper jaw

maxilla

Which prominent structure is intermediate to the occipital condyles?

foramen magnum

Follow the lambdoid suture lateral (away from the midline) and it meets up with two other sutures making an intersection of 3 sutures. Name the other two sutures at this meeting point

squamous

occipitomastoid

Three functions of the skeletal system

a. framework, hemopoiesis

b. protection, mineral reservoir

c. attachment of muscle

Three portions of human axial skeleton

skull

vertebral column

ribs (thorax)

first cervical vertebrae

atlas

superior bone of the skull

parietal

lower jaw

mandible

all 24 ribs articulate here

thoracic vertebrae

largest vertebrae

lumbar vertebrae

nerve cord exits the skull through this opening

foramen magnum

cavity within vertebrae for nerve cord

vertebral foramen

the ventral portion of the hard palate

maxilla

articulate with the superior articular facets

occipital condyles

lateral bone of the skull

temporal

joint of two cranial bones

suture

Dorsal bone of the skull

occipital

superior portion of the sternum

manubrium

How many bones make up the lumbar vertebrae?

5 bones

coastal

5 fused vertebrae make up this portion of the vertebral column

sacrum

Most inferior portion of the sternum

xiphoid process

Which prominent structure is intermediate to the occipital condyles?

foramen magnum

Bone that is not part of the cranium

nasal

Follow the lambdoid suture (away from the midline), and it meets up with two other sutures making an intersection of three sutures. Name the two other sutures at this meeting point

coronal, occipital mastoid
