Fichas del conjunto (20)
- 1—skull
braincase made of flat bones, rest of skull made of irregular bones
- 2—atlas (C1 vertebra)
first vertebra in the spinal column, first vertebra in the cervical region
note: all vertebrae are irregular bones - 3—axis (C2 vertebra)
second vertebra in the spinal column, second vertebra in the cervical region
note: all vertebrae are irregular bones
- 4—cervical region of spine (C)
7 vertebrae (first two are atlas and axis); vertebra identification clue: bilateral transverse foramina on either side of vertebral foramen
note: all vertebrae are irregular bones
- 5—thoracic region of spine (T)
13 vertebrae (this image omits T12-T13); T11 is the anticlinal vertebra where features begin to change; vertebra identification clue: prominent dorsal process
note: all vertebrae are irregular bones
- 6—lumbar region of spine (L)
7 vertebrae; vertebra identification clue: prominent transverse process
note: all vertebrae are irregular bones
- 7—sacrum/sacral region of spine (S)
3 fused vertebrae; connects to ilium at sacraliliac joint; vertebra identification clue: long due to fusion and six dorsal foramina
note: all vertebrae are irregular bones
- 8—coccygeal/caudal region of spine (Cy/Cd)
number of vertebrae varies based on tail length; vertebra identification clue: smallest and simplest vertebrae
note: all vertebrae are irregular bones
- 9—scapulae (singular: scapula)
shoulder blade, flat bones; supraspinatus fossa on lateral cranial aspect, infraspinatus fossa on lateral caudal aspect; scapular spine is the prominent plate of bone running down lateral surface; acromion is the distal peak of the spine
- 10—humerus
long bone of the proximal forelimb
- 11—radius (left, shorter bone)
ulna (right, longer bone)
long bones of the distal forelimb
- 12—forefoot
includes carpus (short bones), metacarpals (long bones), and proximal/middle/distal phylanges (long bones)
- 13—ribs
26 flat bones that form the rib cage to surround the thorax (13 bilaterally); first 9 bones connected by cartilage to sternum ("true ribs"), #10-12 connected by cartilage to preceding rib ("false ribs"); #13 not connected ("floating rib")
- 14—pelvis
irregular bone ventral to sacrum; includes ilium (large portion dorsal to obturator foramina, connects to sacrum at sacroiliac joint), ischium (portion caudal and lateral to foramina), and pubis (portion cranial and medial to foramina)
- 15—femur
long bones of the proximal hindlimb, fits into pelvis at a ball-and-socket joint
- 16—ball-and-socket joint
partially spherical epiphysis lies in a socket, allowing multi-directional range of motion
- 17—patellae (singular: patella)
kneecap; sesamoid or "floating" bone embedded in a tendon
- 18—tibia (larger bone)
fibula (thinner bone)
long bones of the distal hindlimb
- 19—hindfoot
includes tarsus (short bones), metatarsals (long bones), and proximal/middle/distal phylanges (long bones)
- 20—nail (left) encases distal phalange (right)
