Term
Costal Facets
(Vertebrae)
Definition
Transverse: where a rib forms a joint with the transverse process of a vertebra.
Superior- where a rib forms a joint with the top of a vertebra.
Inferior-where a rib forms a joint with the bottom of a vertebra.
Term
Structures of Theoretic Vertebrae
Definition
Compose the middle segment of the vertebral column
Body- heart shaped
pedicles- directed backwards, slightly upward,inferior vertebral notches are of large size, and deeper than in any other region of the vertebral column.
Lamine- they overlap those of subjacent vertebrae like tiles on a roof
foramen- small and circular
Spinous process-long, triangular on coronal section, directed obliquely downward
Superior articular processes-hin plates of bone projecting upward from the junctions of the pedicles and laminae
inferior articular processes-fused to a considerable extent with the laminae
Transverse process- arise from the arch behind the superior articular processes and pedicles;
Term
Structures of Lumbar vertebrae
Definition
largest segments of the movable part of the vertebral column.
the absence of facets on the sides of the body
Term
Manubrium
Definition
the broad, upper part of the sternum
Term
Jugular Notch
Definition
It is a large, visible dip.
Term
Sternal Angle
Definition
formed by the junction of the manubrium and the body of the sternum
Term
Sternal Body
Definition
body of sternum
Term
Xiphoid Process
Definition
the lower part of the sternum
Term
Sternochondral Joints
Definition
Are arthrodial joints, with the exception of the first, in which the cartilage is directly united with the sternum
Term
True Ribs
Definition
The First 7 ribs connected behind with the vertebral column, and in front, through the intervention of the costal cartilages, with the sternum
Term
False Ribs
Definition
ribs 8-12, has no connection to the sternum
Term
Floating Ribs
Definition
Last 2 ribs only attached the vertebrae
Term
Costochondral Joints
Definition
the articulations between the ribs and costal cartilage.
Term
Anterior superior Iliac Spine
Definition
the anterior extremity of the iliac crest of the pelvis, which provides attachment for the inguinal ligament, the sartorius muscle
Term
Angle of Rib
Definition
the bending part of it, and a prominent line in this area
Term
Iliac Crest
Definition
the superior border of the wing of ilium and the superolateral margin of the greater pelvis
Term
Pubis
Definition
the ventral and anterior of the three principal bones composing either half of the pelvis
Term
Pubic Tubercle
Definition
a prominent forward-projecting tubercle on the upper border of the medial portion of the superior ramus of the pubis
Term
Inguinal Ligament
Definition
a band running from the pubic tubercle to the anterior superior iliac spine.
Term
Superficial inguinal ring
Definition
a triangular opening that forms the exit of the inguinal canal, which houses nerves
