pelvic girdle and lower limbs Flashcards
pelvic girdle
The left and right ossa coxae
What does os coxae mean
hip bone
What does pelvis mean
basin
What are the bones of the pelvis
left and right ossa coxae, sacrum, coccyx
What does the pelvis support
the urinary bladder, reproductive organs, and in pregnant women the developing fetus
Sacroiliac joints
the articulation of the ossa coxae and the sacrum
bones of an os coxae
ilium, ischium, and pubis
When do the bones of an os coxae fuse
between ages 13 and 15
acetabulum
deep curved depression that articulates with the femur
What does acetabulum mean
vinegar cub
What does Ilium mean
flank
Auricular surface
Where the ilium articulates with the fused vertebrae of the sacrum
iliac crest
superior most ridge of the ilium
Anterior superior iliac spine
Anterior point of the iliac spine
Posterior superior iliac spine
posterior point of the iliac spine
Fossa lumbales laterales
dimples of venus. the dimples in a person’s lower back. caused by the posterior superior iliac spine
What does ischium mean
hip
ischial tuberosity
posterolateral border of the ischium with a roughened projection. you sit on it
sit bones
ischial tuberosity
obturator foramen
space formed by the rami of the pubis and ischium
symphysis pubis
where the two pubis bones articulate
False pelvis
upper portion of the pelvis. forms the inferior portion of the abdominal cavity
true pelvis
lower portion of the pelvis
Pelvic outlet
inferior exit from the true pelvis. bound by the pubic symphysis, the ischial tuberosities, and the coccyx
Pelvimetry
used to determine if a normal vaginal birth is possible
Caesarian section
C-section
Parturition
child birth
relaxin
Hormone that loosens the symphysis pubis and the sacroiliac joint to increase the diameter of the true pelvis and pelvic outlet to facilitate parturition
How many bones are a lower limb
30
What are the bones of the lower limbs adapted for
weight bearing and locomotion
What does femur mean
thigh
How much pressure is require to fracture the femur
approximately 2,000 pounds per square inch
Head of the femur
articulates with the acetabulum
Fovea
depression in the head of the femur for a tiny ligament to connect the femur to the acetabululm
hip fractures
fracture of the neck of the femure
Greater trochanter
Means runner
lesser trochanter
located on the femurs posteromedial surface
What does linea aspera mean
rough line
linea aspera
roughened midline ridge on the posterior portion of the the shaft of the femur
patellar surface
Where the patella articulates with the femur
intercondylar fossa
deep depression that separates the medial and lateral condyles on the posterior surface of the femur
What does patella mean
small plate
Base
superior flat part of patella
Apex
inferior point of patella
Articular facets of patella
Articulate with the medial and lateral condyles of the femur
interosseous membrane
dense regular connective tissue which helps stabilize the relative positions of the tibia and fibula (and radius and ulna)
What does Tibia mean
large shinbone
Medial and lateral condyles of the tibia
broad flat surfaces that articulate with the medial and lateral condyles of the femur
intercondylar eminence
separates the medial and lateral condyles of the tibia
Fibular articular facet
on the proximal posterolateral side of the tibia where the fibula articulates with the tibia
Superior tibiofibular joint
The articulation of the tibia and fibula on the proximal end
Tibial tuberosity
on the proximal-anterior portion of the tibial shaft where the patellar ligament attaches
Interosseous (I.O) infusion
life saving procedure done by inserting a needle into the medullary cavity of a bone to inject life saving fluids
Anterior crest
shin
medial malleolus
Thought of as an ankle bone. is actually the distal end of the tibia
What does malleolus mean
small hammer
Fibular notch
on the distal posterolateral side of the tibia where the fibula articulates with the tibia
Inferior tibiofibular joint
Where the tibia and fibula articulate inferiorly
What does fibula mean
clasp or broach
lateral malleolus
prominent lateral knob at the distal end of the fibula
What does Tarsal mean
flat surface
How many tarsal bones are there
7
Talus
articulates with both the tibia and the fibula
What does talus mean
ankle bone
Calcaneus
heel bone
Hallux
great toe
What are the arches of the foot
medial and lateral longitudinal arches and the transverse arch
