|---|---|
| Process located on the proximal femur? | trochanter |
| What serves as a base for the trunk? | pelvis |
| Large opening created by the joining of 2 bones of the pelvis | obturator foramen |
| The pelvis consist of what bones? | right innominate (hip) bone, left innominate bone, sacrum and coccyx |
| The posterior portion of the pelvis is made up of what? | sacrum and coccyx |
| What are some differences in the pelvic anatomy of males? | heavier, narrower, and deeper pelvis; angle at pubic symphysis is acute; openings are more heart shaped or round |
| What two portions are is the pelvis divided into by an oblique plane that extends from the upper margin of sacrum to upper margin of pubic symphysis? | Greater (false) pelvis and the Lesser (true) pelvis |
| Pelvic Brim | plane formed by circling from the upper sacrum to the upper margin of the symphysis pubis |
| The _______ is the area between the inlet and outlet of the pelvis. | Pelvic cavity |
| What is another name for the hip bone besides innominate? | os coxae |
| What three bones make up one hip bone? | ilium, ischium and pubis |
| When the three bones of the hip come together what do they form? | acetabulum |
| What are some differences in the pelvic anatomy of females? | wider, shallower, lighter pelvis; angle at symphysis is obtuse; crests are flared outward; iliac spines are further apart |
| The broad , curved portion of the ilium is called the _______ | ala |
| What are two promionent process found on the anterior portion of the ilium | ASIS and AIIS |
| What are two prominent processes found on the posterior portion of the ilium? | PSIS and PIIS |
| What is the most superior portion of the ilium? | iliac crest |
| iliac fossa is a term that can also be used for what? | ala |
| Articulates with the superior lateral portion of the sacrum | Auricle fossa |
| Where is the Greater sciatic notch located? | It is located posteriorly below the auricle fossa |
| Articlutes with the inferior ramus of the pubis | ishial ramus |
| Expanded portion on which the trunk rests when seated | Ischial tuberosity |
| Measured during child birth | ischial spine |
| What are the three parts of the pubis? | body, superior ramus and the inferior ramus |
| What joint do the pubis bones form? | pubic symphysis |
| Junction of ischial ramus and pubis inferior ramus | obturator foramen |
| What is the name of the joint where the right and left ilia and the sacrum meet? | sacroiliac (SI) joints |
| What kind of joint is the hip joint? | ball and socket joint |
| What are some landmarks that can be used to localize anatomy? | Iliac crest, ASIS, pubic symphysis, greater trochanter, ischial tuberosity, tip of coccyx |
| The pubic symphysis lies in the same plane as _________ | the greater trocahtner |
| Horizontal plane as the midpoint of the hip joint and coccyx | Highest point of the greater trocahnter |
| What is the hip joint localization technique? | Palpate ASIS and superior margin of pubic symphysis, draw a line connecting the two, and then draw a line at a right angle to midpoint of the above line. Line will parallel femoral neck |
| The sacroiliac joint is a _______ joint. | gliding |
