Lacrimal bones | make up part of the orbit (socket of the eye) at the inner angle. |
Inferior Conchae | are the thin, scroll-like bones that form part of the interior of the nose (singular, concha). |
Vomer bone | forms the base for the nasal septum. |
Nasal septum | cartilage wall that divides the two nasal cavities |
Mandible OR Jawbone | is the only movable bone of the skull. The mandible is attached to the skull at the temporomandibular joint |
Throacic Cavity OR Rib cage | is the bony structure that protects the heart and lungs. It consists of the ribs, sternum, and upper portion of the spinal column extending from the neck to the diaphragm, but not including the arms. |
RIBS OR Costals | 12 pairs of ribs attach posteriorly to the thoracic vertebrae |
TRUE ribs (who woudlve thought a rib could be false) | First 7 pairs of ribs, attached anteriorly to the sternum |
FALSE ribs (the wrong ribs shame on them) | after the true ribs (the next 3 pairs) they attach anteriorly to cartilage that connects them to the sternum. |
FLOATING ribs (these ribs are quite talented) | they are only attached posteriorly to the vertebrae but are not attached anteriorly. |
Sternum OR BOOB bone (breast bone) | is a flat, dagger-shaped bone located in the middle of the chest. By joining with the ribs, it forms the front of the rib cage. This is divided into three parts |
Manubrium | is the bony structure that forms the upper portion of the sternum. |
body of the sternum | is the bony structure that forms the middle portion of the sternum. |
Xiphoid process | is the structure made of cartilage that forms the lower portion of the sternum. |
Pectoral girdle OR Shoulder girdle | which supports the arms and hands |
Clavicle OR Collar bone | is a slender bone that connects the manubrium of the sternum to the scapula. |
Scapula | shoulder blade |
Acromion | is an extension of the scapula that forms the high point of the shoulder. |
Humerus | is the bone of the upper arm |
Radius | is the smaller and shorter bone in the forearm. The radius runs up the thumb side of the forearm (plural, radius bones). |
Ulna | is the larger and longer bone of the forearm (plural, ulnae). The proximal end of the ulna articulates with the distal end of the humerus to form the elbow joint. |
Olecranon process OR Funny bone | is a large projection on the upper end of the ulna. This forms the point of the elbow and exposes a nerve that tingles when struck. |
Carpals | 8 that form the wrist These bones form a narrow bony passage known as the carpal tunnel. The median nerve and the tendons of the fingers pass through this tunnel to reach the hand. |
Metacarpals | 5 bones that form the palm of the hand |
Phalanges | 14 bones of the fingers each of the 4 fingers has 3 bones |
Spinal column OR Vertebral Column | protects the spinal cord and supports the head and body. The spinal column consists of 26 vertebrae |
Body of the vertebrae | anterior portion of the vertebrae |
Lamina | posterior portion of the vertebrae The transverse and spinous processes extend from this area and serve as attachments for muscles and tendons. |
Vertebral foramen | is the opening in the middle of the vertebra. This opening allows the spinal cord to pass through and to protect the spinal cord |
Intervertebral disks | which are made of cartilage, separate and cushion the vertebrae from each other. They also act as shock absorbers and allow for movement of the spinal column |
