Gluteal Region Flashcards
(107 cards)
boundaries of the gluteal region
iliac crest, intergluteal cleft (natal cleft), gluteal fold
How is the femur adapted in regards to our center of gravity
they are oblique so that they can be as close to the center of gravity axis as possible. midline.
where is our center of gravity really located?
L5
Coxa valga
when the angle between the head and neck of the femur (medial) is larger that 135
Coxa Vara
when the angle between the head and neck of the femur is less than 120
coxa norma
when the angle between the head and neck of the femur is between 135 and 120
True (lesser) pelvis vs false (greater) pelvis
false pelvis contains abdominal viscera and extends from the iliac crest down to the pelvic brim. The true pelvis extends from the pelvic brim to the perenium and contains our reproductive organs.
which 3 bones make up the os coxae
ilium, ischium and pubis
whats special about the os coxae?
the three bones are connected by triradiate cartialge during childhood (black on radiograph). the three bones begin to fuse (where the Y shaped triradiate cartilage is) around puberty.
Important features of the os coxae
greater sciatic notch, ischial spine, lesser sciatic notch, ischial tuberosity, acetabulum, pubic tubercle, anterior inferior iliac spine, anterior superior iliac spine, posterior superior iliac spine, posterior inferior iliac spine, obturator groove, pectineal line, superior pubic ramus, inferior pubic ramus, ramus of ischium, body of ischium. gluteal lines (all three)
More to know for the bones
greater sciatic foramen, lesser sciatic foramen, sacrospinous ligament, sacrotuberous ligament, obturator foramen, margin of pelvic inlet
which ligament separates the greater sciatic foramen form the lesser sciatic foramen?
sacrospinous ligament which connects the sacrum to the ischial spine
which ligament connects the sacrum to the ischial tuberosity?
sacrotuberous liagment
what passes through the lesser sciatic foramen?
obturator internus muscle tendon, nerve to obturator internus muscle, internal pudendal vessels, pudendal nerve
what passes through the Greater sciatic foramen
piriformis muscles fills the foramen; provides pathway for superior and inferior gluteal vessels and nerves, internal pudendal vessels, pudendal nerve, posterior femoral cutaneous nerve, nerves to obturator internus and quadratis femoris muscle.
inguinal ligament attachement
anterior superior iliac crest to the pubic tubercle
what runs under the inguinal ligament
femoral artery (runs down), femoral vein (runs up), femoral nerve
what type of joint is the sacroiliac joint?
synovial
differences between male and female pelvis?
female=circular pelvic inlet and wider angle between the pubic symphysis
Male=heart shaped pelvic inlet and smaller angle between pubic symphysis
How is the length of the femur related to height?
height=femur length x 4
know the following femur bone structures
Head, neck, greater trochanter, lesser trochanter, angle of inclination, intertrochanteric line, shaft, lateral epicondyle, lateral condyle, patellar surface, medial condyle, medial epicondyle, adductor tubercle, fovea for ligament of head, trochanteric fossa, intertrochanteric crest, quadrate tubercle, pectineal line, spiral line, gluteal tuberosity, lateral and medial lips of the linea aspera, medial and lateral supracondylar line, popliteal surface, adductor tubercle, medial and lateral epicondyles, intercondylar line, medial and lateral condyles, intercondylar fossa
What attaches to the adductor tubercle?
the hamstring portion of the adductor magnus
what is on the head, patellar surface and medial and lateral condyles of the femur?
articulate cartilage
What attaches to the greater trochanter?
insertion site of the gluteus medius, gluteus minimus, piriformis and obturator internus
