two os coxae, sacrum, coccyx
What 7 bones make up the lower extremity?
(os coxa) Which are the 3 gluteal lines on the ala?
(os coxa) What are the gluteal lines function?
mark the origins of gluteal muscles
(os coxa)what 3 fused bones is the ox coxa made off?
(os coxa) What 2 parts is the illium divided into?
body and the ala
(os coxa)(ilium) what does the body help to form?
**the body is the thickest part of that helps form the os coxa
(os coxa)(illium) What does the ala form?
the upper crest of the illium
(os coxa) which is the smallest of the 3 bones?
(os coxa)(pubis) What does the inferior ramus of pubis help form?
the lower edge of the optic foramen
(os coxa)(ilium) what does the posterior superior iliac spine indicate?
the end of the iliac spine
(os coxa) What is the greater sciatic notch?
is a deep indentation on the posterior side
(os coxa)(ischium) What is the ischial spine? (2)
-attachment for some ligaments
-separates the greater sciatic notch and the lesser sciatic notch
(os coxa)(ischium) What is the ischial tuberosity? (3)
-rough area used for muscle attachment
-it is one of the bones we sit on
-also the attachment of ligaments
(os coxa) What part of the os coxa does the ischium form?
interior and posterior part of os coxa
(os coxa) What happens at the pubic symphysis?
the left and right pubis articulate
(os coxa) What can be determined by observing the pubic arch?
-the wider the gap, means that it is a male
- ***male: 50-60 degrees

from the hip to the knee
what is considered as the leg?
from the knee to the ankle
what is considered as the foot?
distal to the ankle
(femur) what does the neck of femur do?
connects the head to the shaft
(femur) What is the patella surface?
a smooth surface between the condyles anteriorly that articulates with a small bone called patella
(femur) What is the fovea capitis? and what does it do? (2)
-it is a small depression at the center of the head for the attachment of a ligament of the head of femur
-helps hold the head of femur in the acetabulum
(femur) Where does the head of the femur articulate?
with the acetabulum
(femur) what is the lesser trochanter attachment for?
(femur) what is the gluteal tuberosity an attachment for?
(femur) what is the linea aspera?
-rough vertical line on the posterior side of the femur that is used as muscle attachment
(femur) What does the intercondyle notch do?
separates the condyles of the femur on the posterior and femur sides
(femur) what does the medial condyle do?
-it is a rounded smooth distal structure that is used for articulation with medial condyle of tibia
(femur) what does the lateral condyle do?
-its a rounded smooth distal structure in the lateral side of the femur for articulation with the lateral condylar with tibia
(femur) What attaches to the abductor tubercle?
it is a muscle attachment
FEmur is the _______ and _____ bone in the body
what two structures does the femur articulate with?
- acetubulum in the coaxa and tibia at the knee joint
- ***also with patella
does the fibula articulate directly with the femur?
is the fibula a weight bearing bone?
which of the 2 bones receives the weight? tibia or fibula?
(tibia)what is the intercondyler eminence?
-it is a raised area between medial and lateral facets that projects onto the intercondylar notch of the femur
(tibia) Medial condyle (2)
-articulates with medial condyle of the femur
-contains a smooth oval surface called medial facet or articular surface
(tibia) Lateral condyle (2)
-articulates with lateral condyle of the femur
-contains a smooth rounded surface, lateral facet, or articular surface
(tibia) tibial tuberosity
-it is a large bump which is the site of attachment of a ligament
(tibia)what is the anterior crest?
long broder that runs from tibial tuberosity to medial malleolus
(tibia) medial malleous
- -projects medially above the ankle joint
- *medial ankle bone
-also called calf bone
-serves mainly for muscular attachments
(fibula) lateral malleous
forms lateral ankle bone
