The phalangeal formula is 2,3,3,3,3 |
|
|
Term

|
Definition
| 3; proximal, middle, and distal |
|
|
Term
| What two bones does the pelvic (hip) bone consist of? |
|
Definition
| Constists of two coxal bones and the hip bones, pubic symphis and the sacrum. |
|
|
Term
| What is the joint between the two coxal bones? |
|
Definition
|
|
Term
| What other joint does the pelvic bone create. |
|
Definition
| both coxal bones united posteriorly with the scrum joints. |
|
|
Term
| The bony pelvis consists of what bones? |
|
Definition
| Hip bones, pubic symphis, and ths sacrum. |
|
|
Term
| What three "fused" bones does each hip bone consist of? |
|
Definition
| ILium (superior), Pubis (inferior and anterior), and ischium (inferior and posterior). |
|
|
Term
|
Definition
| The true (lesser pelvis is the part of the pelvis inferior to the pelvic brim. |
|
|
Term
| What is the false pelvis? |
|
Definition
| The false (greater) pelvis is the portion of the bony pelvis superior to the pelvic brim. |
|
|
Term
| What sets the female pelvis apart from the male pelvis? |
|
Definition
The female pelvis is light and thin while the males is heavy and thick.
The female's pelvic brim is larger and more oval while the males' is smaller and heart shaped. The females acetabulum is small and faces anteriorly while the males' acetabulum is large and faces laterally. The females obturator foramen is oval and the male's is round. The females pubic arch is greater than 90% and the males pubic arch is less than 90%. The female coccyx is more moveable and points inferiorly while the male is less moveable and points anteriorly. |
|
|
Term
| What characterizes the femur? |
|
Definition
| Longest, heaviest, and strongest bone in the body. The proximal end articulates with the acetabulum of the hip bone. The distal end articulates with the tibia and patella. |
|
|
Term
|
Definition
| KNee cap. Articulates with the lateral and medial condyles of the femur. |
|
|
Term
|
Definition
| The shin bone. The larger medial wight bearing bone of the leg. |
|
|
Term
| What bones deos the tibia articulate with? |
|
Definition
| The proximal end articulates with the femur and fibula. The distal end articulates with the fibula and talus bone. |
|
|
Term
| Where is the fibula located? |
|
Definition
| Parallel and lateral to the tibia. It is smaller than the tibia. The proximal end (head) articulates with the lateral condyle of the tibia. Forms the proximal tibiofibular joint. The distal end (lateral malleolus) articulates with the talus bone of the ankle and with the fibular notch of the tibia. |
