Vertebral Column

Atlas-1st cervical vertebrae

Axis-2nd cervical vertebrae

Sacrum-fused between the 2 hip bones, normally around 5

Coccyx-tailbone

Vertebral Features

Body of the vertebrae-solid portion of the vertebrae, holds the weight

Spinous Process-sticks out on the back

Vertebral discs-fibrocartilage between disks that act as padding

Vertebral foramen-hole for spinal cord to go through

Transverse process-stick out laterally, form a T

Thoracic Cage

Costal Cartilage-connects ribs to sternum

True ribs-1st seven pairs of ribs-connect directly to sternum with costal cartilage

False ribs-3 pair at the bottom

Floating ribs-attached to T12 but doesn't attach to the sternum

Jugular notch-between the collar bones

Manubrium-wide portion of the sternum (the handle)

Sternum body-sternum (blade)

Xiphoid process-bottom of sternum (point of blade)

Appendicular Skeleton

Pectoral Girdle

Clavicle-collar bone

Scapula-shoulder blade

Acromion Process-sticks out on the shoulder blade (furthest out)

Coracoid process-sticks out of the shoulder blade...closest to ribs

Glenoid cavity (fossa)-flat area where the shoulder blade articulates with the head of the humerus

Upper Appendage

Humerus-long upper arm bone

Olecranon process- elbow (point of elbow)..end of ulna

Ulna-pinkie side (on top)

Radius-thumb side (underneath)

Carpals-wrist (8) scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, hamate

Pelvic Girdle

Acetabulum-socket where the femur attaches in pelvis

False Pelvis-upper portion of the hip (elephant ear)

Greater sciatic notch-notch in pelvis, near tailbone Ilium-top of the wide bone, top of the elephant ear

Ischium-loops that you sit on Obturator foramen-hole in Ischium

Os Coxa-one whole side of the hip, formed by the fusion of the ilium, ischium, and pubis

Pubis symphysis-cartilage btw pubic bones

Pubis-bone in the front of the pelvis True pelvis-makes a circle, bottom

Lower appendage

Calcaneus-heel, one of ankle bones

Cuneiform bones-square like bones in the ankle-top of foot

Femur-longest, strongest bone

Fibula-skinny leg bone (outside)

Tibia-stronger bone in calf region (tibia-toes)
