lower appendicular - skeletal bones

ilium

the ridge of the major portion of the os coxa. articulates with the sacrum

ischium

the distal, rounded, posterior portion of the os coxa. you sit on this part

pubis

the most anterior portion of the os coxa

acetabulum (acetabular fossa)

the huge fossa on the lateral side of the os coxa. This is the socket for the ball and socket joint of the leg

obturator foramen

the huge hole immediately inferior to the acetabulum

iliac crest

superior rim of the ilium

anterior superior iliac spine

the subtle bump on the anterior edge of the iliac crest

anterior inferior iliac spine

the subtle bump on the anterior edge of the iliac crest inferior to the anterior superior iliac spine

posterior superior iliac spine

a subtle bump on the posterior edge of the iliac crest

posterior inferior iliac spine

a subtle bump on the posterior edge of the iliac crest inferior to the posterior superior iliac spine

greater sciatic notch

a huge notch on the posterior side of the os coxa and inferior to the posterior inferior iliac spine

ischial spine

a pointy projection inferior to the distal aspect of the greater sciatic notch

head

the rounded portion at the proximal end of the femur that articulates with the acetabular fossa. The head is positioned medially

fovea capitis

a depression in the center of the head of the femur

greater trochanter

a rather large bulge lateral to the head of the femur

neck

the area between the head of the femur and the greater trochanter

lesser trochanter

a small bulge inferior to the neck of the femur located mostly on the medial aspect of the femur

medial condyle

a rounded process located at the distal end of the femur on the medial side. it is best seen on the posterior view of the femur

lateral condyle

a rounded process located at the distal end of the femur on the lateral side. it is best seen on the posterior view of the femur

intercondylar fossa

a depression between the medial and lateral condyles. this is the location for the anterior and posterior cruciate ligaments

medial epicondyle

a bulge that is medial to the medial condyle

lateral condyle

a bulge that is lateral to the lateral condyle

intertrochanteric line

a small ridge extending from the greater trochanter to the lesser trochanter on the anterior side

intertrochanteric crest

a small ridge extending from the greater trochanter to the lesser trochanter on the posterior side

linea aspera

a subtle ridge extending from the lesser trochanteric down the center of the posterior femur

medial supracondylar line

a subtle ridge extending from the distal end of the linea aspera and angles medially

lateral supracondylar line

a subtle ridge extending from the distal end of the linea aspera and angles laterally

base

sort of flat in appearance. it is the superior portion of the patella

apex

sort of pointy area at the inferior end of the patella

intercondylar eminence

a pair of bumps on the most superior aspect of the tibia

intercondylar tubercles

each individual bump that comprises the intercondylar eminence. (left and right)

tibial tuberosity

a bulge just a few centimeters inferior to the patella on the anterior side. located proximally on the tibia

anterior border

a ridge that runs down the middle of the anterior tibia

medial malleolus

a bulge on the distal, medial end of the tibia. located medial to the ankle bones

head

proximal end of the fibula. sort of triangular shaped

lateral malleolus

a bulge on the distal, lateral end of the fibula. located lateral to the ankle bones

talus

the most superior tarsal bone. the tibia articulates with this bone

calcaneus

the most posterior tarsal bone

navicular

anterior to the talus

medial cuneiform

anterior to the navicular

intermediate cuneiform

anterior to the navicular and lateral to the medial cuneiform

lateral cuneiform

anterior to the navicular and lateral to the intermediate cuneiform

cuboid

lateral to the lateral cuneiform
