Bones

Front 1

List the two divisions of the skeletal system.

Back 1

Axial Skeleton and Appendicular Skeleton

Front 2

The skeletal division that includes the bones of the head, trunk, skull bones, vertebrae, hyoid, ribs and sternum is the

Back 2

Axial Skeleton

Front 3

The skeletal division that includes bones of the appendages and their girdles is the

Back 3

Appendicular Skeleton

Front 4

List 3 regions of the skull

Back 4

Cranial, facial and orbital.

Front 5

Cranial bones inculde:

Back 5

Frontal, parietals, occipital, sphenoid, ethmoid, and temporal bones.

Front 6

Facial bones incude:

Back 6

Maxillaries, zygomatics, nasals, lacrimals, vomer, palatines, and mandible.

Front 7

Orbital bones include:

Back 7

Maxillaries, zygomatics, frontal, sphenoid, ethmoid, lacrimal and the palatines.

Front 8

Sphenoid Bone articulates with:

Back 8

The Frontal and Parietal-superiorly,
and anteriorly with the zygomatic.

Front 9

The anterior projection of the temporal is the

Back 9

Zygomatic process of the Temporal Bone.

Front 10

The posterior projection of the zygomatic is the

Back 10

Temporal Process of the Zygomatic

Front 11

Zygomatic articulates with:

Back 11

Posterior-Sphenoid, Superior-Frontal

Front 12

What are the names and the number of teeth on each side of the jaw?

Back 12

Beginning at the midline-First 2 are incisors, then 1 canine, 2 premolars, and up to 3 molars.

Front 13

Ethmoid articulates with

Back 13

the Frontal superiorly, Maxillary inferiorly, and the sphenoid posteriorly.

Front 14

Where is the Hyoid bone and what is special about it?

Back 14

Hyoid bone supports the tongue. It is U-shaped and does not attach to the axial skeleton.

Front 15

List the parts of the vertebral column and number of vertebrae

Back 15

7-Cervical
12-Thoracic
5-Lumbar
5-Fused Sacral
3-5-Fused Coccygeal

Front 16

Cervical Vertebrae-Atlas

Back 16

C1-looks like a large ring with small transverse processes, body is absent.Has large superior articulating facets to articulate with the occipital bone.

Front 17

Cervical Vertebrae-Axis

Back 17

C2- short, broad spinous process, short transverse process, body has a superior projection that rests inside the vertebral canal of the atlas, this is called the DENS

Front 18

Other features of Cervical Vertebrae-

Back 18

Spinous Processes are Bifid. Transverse Processes of all 7 cervical have foramina called the transverse foramen.

Front 19

Thoracic vertebrae can be distinguished by-

Back 19

Facets for rib attachment, long spinous processes that point inferiorly, heart shaped body.

Front 20

Clavicle-S-shaped bone-articulates?

Back 20

Medial end articulates with the Manubrium and lateral end articulates with the scapula.

Front 21

Humerus articulates superiorly with

Back 21

the glenoid cavity of the scapulae

Front 22

Humerus identification-

Back 22

Proximal end is rounded and fits into the glenoid cavity, spool shaped feature at the distal end. The Posterior, distal end has a LARGE DEPRESSION.

Front 23

Ulna-

Back 23

Medial most bone of the antebrachial area. Has a deep, U-shaped notch anteriorly at the proximal end called the TROCHLEAR NOTCH-articulates with the HUMERUS

Front 24

Radius-

Back 24

lateralmost bone of the arm. Its proximal end is rounded and flat and articulates with the shallow notch at the lateral surface of the ulna and the lateral portion of the spool of the humerus.

Front 25

Tibia

Back 25

Lower leg, large medial bone. Proximal end has two large flat surfaces, which articulate with the femur. Distal end has a medial projection that can be used to identify the medial and lateral surfaces of the bone.
