1

The fused bones at the inferior end of the vertebral column

Coccyx

2

A mesenchyme-filled space where bone formation is not yet complete, especially between the cranial bones of an infant's skull

Fontanel

3

A passage or opening; a communication between two cavities of an organ, or a hole in a bone for passage of vessels or nerves. 

Foramen

4

Any break in a bone

Fracture

5

A plane at a right angle to a midsagittal plane that divides the body or organs into anterior and posterior portions. Also called a coronal plane

Frontal plane

6

A rupture of an invertebral disc so that the nucleus pulposus protrudes into the vertebral cavity. Also called a slipped disc

Herniated disc

7

 A pad of fibrocartilage located between the bodies of two vertebrae

Intervertebral disc

8

An exaggeration of the thoracic curve of the vertebral column, resulting in a "round-shouldered" appearance. Also called hunchback

Kyphosis

9

The joint in the skull between the parietal bones and the occipital bone; sometimes contains sutural (Wormian) bones

Lamboid suture

10

An exaggeration of the lumbar curve of the vertebral column. Also called hollow back

Lordosis

11

The appendage attached at the pelvic (hip) girdle, consisting of the thigh, knee, leg, ankle, foot, and toes. Also called the lower extremity

Lower limb

12

A vertical partition composed of bone (perpendicular plate of enthmoid GLOSSARY and vomer) and cartilage, covered with a muccous membrane, separating the nasal cavity into left and right sides

Nasal septum

13

The bony, pyramidal-shaped cavity of the skull that holds the eyeball

Orbit

14

The branch of medecine that deals with the preservation and restoration of the skeletal system, articulations, and associated structures

Orthopedics

15

A mucus-lined air cavity in a skull bone that communicates with the nasal cavity; located in the frontal, maxillary, ethmoid, and sphenoid bones

Paranasal sinus

16

An abnormal lateral curvature from the normal vertical line of the backbone

Scoliosis

17

Small bones usually found in tendons

Sesamoid bones

18

A small bone lcoated within a suture between certain cranial bones. Also called Wormian bone

Sutural bone

19

An immovable fibrous joint that joins skull bones

Suture

20

The chest

Thorax

21

The appendage attached at the shoulder girdle, consisting of the arm, forearm, wrist, hand, and fingers. Also called the upper extremity

Upper limb

22

A cavity within the vertebral column formed by the vertebral foramina of all the vertebrae and containing the spinal cord. Also called the spinal canal

Vertebral canal

23

The 26 vertebrae of an adult and 33 vertebrae of a child; encloses and protects the spinal cord and serves as a point of attachment for the ribs and back muscles. Also called the backbone, spine, or spinal column

Vertebral column
