Orthopedics/ Skeletal System: Medical Term
Intervertebral Disks
Makes up ¼ of the length of the vertebral column and separates most vertebrae.
Sacrum
A group of five fused vertebra that are not individually numbered , except for the first sacral vertebra; S1. The sacrum joins with the hip bones in the posterior pelvis.
Clavicle
A thin, rod-like bone on each side of the anterior neck also known as the collar bone.
Spine, Backbone
A vertical column of bones also known as the vertebral column or spinal column. The vertebral column supports the weight of the head, neck, and trunk of the body and protects the spinal cord.
Frontal Bone
The bone that forms the forehead and top of the cranium and ends at the coronal structure.
Skull
The bony structure of the head.
Cranium
The domelike bone at the top of the head.
Carpal Bones
The eight small bones arranged in two rows within the wrists.
Atlas
The first cervical vertebra: C1 vertebrae which is located directly below the occipital bone of the cranium. Its appearance is different from the other cervical vertebrae because it must form a joint that allows the head to move up and down.
Hyoid Bone
The flat, U-shaped bone in the anterior neck. It does not connect directly to any other bones. It is attached by ligaments to the styloid process of each temporal bone.
Tibia
The large bone on the medial side of the lower leg, also known as the shin bone, and is the largest bone of the body.
Appendicular Skeleton
The part of the skeleton which consists of the bones of the shoulders upper extremities, hips, and lower extremities.
Axial Skeleton
The part of the skeleton which forms the central bony structure of the body around which other parts move; it consists of the bones of the head, chest, and back.
Axis
The second cervical vertebra: C2. Vertebrae which fits into the atlas to form a joint that allows the head to move from side to side.
Spinal Column
The spinal column consists of five regions: cervical vertebrae, thoracic vertebrae, lumber vertebrae, and the sacrum and coccyx. The vertebrae become progressively larger from top to bottom as they bear more and more of the weight of the body.
Vertebral Column
The spine or backbone that contains 24 individual vertebrae, plus the sacrum and coccyx. It is divided into five regions: the cervical vertebrae, the thoracic vertebrae, the lumbar vertebrae, the sacrum, and the coccyx.
Coronal Suture
The suture between the parietal and frontal bones of the skull.
Coccyx
The tail bone. The tail bone or coccyx is a group of several small, fused vertebrae that are not individually numbered.
Lumbar Vertebra
The vertebrae that supports the weight of the entire upper body.
Temporal Bones
Bones that form the lower sides of the cranium.
Parietal Bones
Bones that form the upper sides and posterior parts of the cranium. Between these bones is the sagittal suture, which runs from front to back.
Cervical Vertebrae: C1-C7
C1 through C7 vertebrae's of the neck.
What is the other name for collar bone?
Clavicle
Sternum or Breast Bone
Is in the center of the anterior thorax. It consists of the triangular-shaped manubrium, the body of the sternum, and inferior tip or xiphoid process; sternum; breast bone.
Cranial Cavity
Structure which lies within the cranium and contains the brain and other structures.
What is the medical term for the shin bone?
Tibia
Lumbar Vertebrae
Vertebrae L1 through L5, that are in the lower back. The lumbar vertebrae are larger than the cervical or thoracic vertebrae because they are designed to bear the weight of the head, neck, and trunk of the body.
Thoracic Vertebrae
Vertebrae's T1 through T12 which are located in the chest. Each thoracic vertebra joins with one pair of the 12 pairs of ribs.
