Located in the throat above the larynx and serves as a point of attachment for many tongue and neck muscles. Not considered/counted as a skull bone.
The vertebral column?
Extends from the skull to the pelvis, it forms the body's major axial support. Consists of 24 single bones called vertebrae and two composite, or fused, bones (sacrum & coccyx) that are connected in such way as to provide a flexible curved structure.
24 single bones
Which category of bones contains the following typical features: Body (centrum), Vertebral foramen, Transverse process, and Spinous process.
Which area of the vertebrae contains the vertebrae 1-7, the bones of the neck (contains the atlas: for the 'yes' motion & the axis: for the 'no' motion), and the transverse foramen.
Cervical vertebrae (C1 - C7)
Which area of the vertebrae contains 12 single bones?
Thoracic Vertebrae (T1 - T12)
What does the atlas allow you to do and where is it found?
This joint enables you to nod "yes". It's C1 of the Cervical Vertebrae.
What does the axis allow you to do and where is it found?
It acts as a pivot for the rotation of the atlas (and skull above). Enables you to nod "no". It's C2 of the Cervical Vertebrae.
Name the areas of the vertebral column in order from top to bottom.
Cervical, Thoracic, Lumbar, Sacral, & Coccyx.
Which area of the vertebrae contains 5 single bones and are right below the thoracic vertebrae.
These vertebrae have massive blocklike bodies and short, thick, hatchet-shaped spinous processes extending directly backward.
Which area of the vertebrae is a composite bone formed from the fusion of 5 vertebrae. It articulates with L5 and connects with the coccyx. It contains the sacral canal, the body, and the auricular surface (articulates with the ilium).
Which area is formed from the fusion of 3-5 small irregularly shaped vertebrae? It is the human tailbone and is attached to the sacrum by ligaments.
Combined with the costal cartilages & because of its appearance and because it forms a protective cone-shaped enclosure around the organs of the thoracic cavity, it is referred to as the?
The sternum & the ribs are part of the?
The Vertebrae (Cervical, Thoracic, Lumbar, Sacrum, and Coccyx) is part of the?
The Frontal, Parietal, Temporal, Occipital, Sphenoid, Ethmoid, Mandible, Maxilla, Zygomatic, Lacrimal, Palatine, Inferior Nasal Conchae, Nasal, and Vomer bones are part of the?
The breastbone. A typical flat bone, is a result of the fusion of three bones - the manubrium, the body, and xyphoid process.
It constructs the inferior end of the sternum and lies at the level of the fifth intercostal space. Although it is made of hyaline cartilage in children, it is usually ossified in adults.
Forms the bulk of the sternum
Looks like the knot of the tie; it articulates with the clavicle (collarbone) laterally.
These 12 pairs form the walls of the thoracic cage.
Which are the TRUE ribs? And why are they TRUE ribs?
The first 7 pairs (Ribs 1-7); because they attach directly to the sternum by their "own" costal cartilages.
Which are the FALSE ribs? And why are they FALSE ribs?
Ribs 8-12; they attach indirectly to the sternum or entirely lack a sternal attachment.
Which ribs are the floating ribs? Why are the "floating" ribs?
The last 2 pairs (Ribs 11-12); they have no sternal attachment.
Bridge of nose?
Posterior bones of the hard palate?
Much of the lateral and superior cranium?
Single, irregular, bat-shaped bone forming part of the cranial floor?
Tiny bones bearing tear ducts?
Anterior part of hard palate?

Site of sella turcica?
Site of mental foramen?
Site of styloid processes?
Four bones containing paranasal sinuses?
Ethmoid, Frontal, Maxilla, & Sphenoid.
