Parts of the Spine
is the large, anterior portion of a vertebra—sometimes called the “centrum.” It supports body weight and connects with adjacent vertebrae via intervertebral discs
What is the The Vertebral Body?
Number of pairs of ribs the human body has
What is 12?
commonly known as the shoulder blade, is a flat, triangular bone located on the posterior (back) thoracic wall, overlying approximately ribs 2 through
What is the the scapula?
Is the only bone in the upper arm, stretching from the shoulder to the elbow. It’s one of the longest bones in the human body and plays a pivotal role in upper limb movement.
What is the humerus?
Largest of the proximal row; Located on the thumb (radial) side of the wrist.
What is the Scaphoid?
Is the central opening formed between the vertebral body (anteriorly) and the vertebral arch (posteriorly). These aligned openings across vertebrae form the spinal canal.
What is the The Vertebral Foramen?
These attach directly to the sternum via costal cartilages and the number of pairs we have
What are true ribs and what is 7 pairs?
is an S-shaped bone located anteriorly across the top of the thorax.
What is the clavicle?
Bone in the arm that is on the lateral (thumb side)
What is the Radius?
Crescent-shaped and centrally located in the proximal row.
What is the Lunate?
This structure forms the posterior ring of a vertebra
What is the Vertebral Arch?
Indirectly attached to sternum (through cartilage of rib above) and number of pairs we have
What is false ribs and 3?
the upper, broader segment of sternum
What is Manubrium?
Bone in the arm that is the medial forearm bone (pinky side)
What is the ulna?
On the ulnar (pinky) side of the proximal row; Articulates with lunate, pisiform, and hamate
What is the Triquetrum?
is a single bony projection extending posteriorly in the midline of the vertebra, where the laminae meet
What is the Spinous Process?
Do not attach to the sternum at all and have free anterior ends and number of pairs we have
the long middle portion of the sternum
What is the Gladiolus (body)?
Group of carpals closest to the forearm
What is the Proximal row?
A sesamoid bone embedded in the tendon of the flexor carpi ulnaris.
What is the Pisiform?
Two wing-like projections that extend laterally from the junction of pedicle and lamina; thick with broad ends
What is the The Transverse Process?
Are segments of hyaline cartilage located at the anterior ends of the ribs. They serve to extend the ribs forward, creating a flexible connection between the ribs and the sternum.
What is Coastal cartilage?
the small, cartilaginous lower tip of the sternum
What is the Xiphoid Process?
Group of carpals closer to the hand
What are distal row?
Part of the distal row, sits directly distal to the scaphoid. Articulates predominantly with the thumb's metacarpal (first metacarpal).
What is the Trapezium?
