How many bones of the skeleton are there
206
Skeletal system organized into two divisions
axial and appendicular
composed of the bones along the central axis of the body, which are commonly divided into three regions—the skull, the vertebral column, and the thoracic cage.
Axial skeleton
includes the bones of the upper and lower limbs, and the girdles of bones that attach the upper and lower limbs to the axial skeleton. The pectoral girdle consists of bones that hold the upper limbs in place, whereas the pelvic girdle consists of bones that hold the lower limbs in place
Appendicular skeleton
fibrous joints that connect the bones of the cranium
Sutures
sagittal suture connecting the parietal bones of the skull, lamboid suture connecting the occipital bone with the parietal bones
Examples of sutures
When does the coronal suture usually close
First to close, 20s-30s
When does the sagittal usually close
30s or later
When does the lambdoidal usually close
Usually 40s
When does the squamous usually close
60-plus years or not at all
Which sinuses make up the Paranasal sinuses
ethmoidal, frontal, maxillary, and sphenoidal sinuses
Describe the differences in female and male skulls
“female†features tend to be gracile (delicate, small), “male†features tend to be more robust (larger, sturdier, bulkier).
soft spots on a baby’s head, areas of dense regular connective tissue membrane in regions where infant’s cranial bones are not yet large enough to surround the brain completely
fontanelle
spinal curves present at birth, thoracic and sacral curves
Primary spinal curves
spinal curves appear after birth, cervical and lumbar curves
Secondary spinal curves
abnormal lateral curvature of the spine
scoliosis
swayback, abnormal lumbar curvature
lordosis
hunchback, abnormal thoracic curvature
kyphosis
two parts of an intervertebral disc (IVD)
body of vertabra and vertebral arch
anterior region of vertebra that is thick and cylindrical, also called centrum
Body of vertebra
portion of the vertebra posterior to the vertebral body, also called neural arch
Vertebral arch
What motion does atlas allow
articulation between the occipital condyles and the atlas, called the atlanto-occipital joint, permits us to nod our heads “yes.â€
What motion does the atlantoaxial joint allow
This articulation between the atlas and axis, called the atlantoaxial joint, permits us to shake our heads “noâ€
seventh cervical vertebra characterized by a prominent spinous process which can be felt at the base of the neck
vertebral prominens
gelatinous nucleus pulposus protrudes into or through the anulus fibrosus, produces a bulging of the disc
disc herniation
Ribs 1-7, connect to the sternum by costal cartilage
true ribs
ribs 8-10, do not attach directly to the sternum
false ribs
How to tell male from female pelvis
Male is taller than they are wide (upside down martini glass), Female is wider than they are tall (upside down margarita glass)

Bone that does not make a joint with any other bone
hyoid bone
makes tempromandibular joint
Condylar process
Another name for Dens
Odontoid process
C1 pivots on C2 at the
Dens/Odontoid process
Transverse foramen is only in the
cervical spine
