(6) Anatomy - Appendicular Skeleton: Lower Extremities

**Femur** bone

How many landmarks are there of the **Femur?** List them?

10

head of the femur

neck of the femur

greater trochanter

lesser trochanter

medial condyle

lateral condyle

medal epicondyle

lateral epicondyle

intercondylar fossa

patellar groove/surface

Femur - head of the femur

the ball-like proximal end of the femur inserts into the acetabulum of the coxa

Femur - neck of the femur

Femur - greater trochanter

the trochanters are attachment sites for the hip muscles moving the femur

Femur - lesser trochanter

the trochanters are attachment sites for the hip muscles moving the femur

Femur - medial condyle

large rounded bumps on the distal end of the femur. The condyles bear weight while also allowing movement at the knee. A ligament attached to the medial condyle of the femur helps hold the tibia in place

Femur - lateral condyle

large rounded bumps on the distal end of the femur. The condyles bear weight while also allowing movement at the knee.

Femur - medal epicondyle

bumps on the medial side of the distal femur located just superior to the condyles. they are muscle attachment sites

Femur - lateral epicondyle

bumps on the lateral side of the distal femur located just superior to the condues. They are muscle attachment sites

Femur - intercondylar fossa

(posterior view)

\
an attachment site or ligaments holding the femur and tibia together

Femur - patellar groove/surface

where your patella (knee) attaches

\
a small depression on the anterior side of the distal end of the femur. the patella moves within the patellar groove when the leg moves

**Patella** bone

the knee/kneecap

**Tibia** bone

**T**ibia = **t**hick

How many landmarks does the **Tibia** bone have? List them

5

medial condyle

lateral condyle

intercondylar eminence

tibial tuberosity

medial malleolus

Tibia - medial condyle

region on the proximal end of the tibia that articulates with the condyles of the femur.. the condyles bear weight while also allowing movement at the knee

Tibia - lateral condyle

region on the proximal end of the tibia that articulates with the condyles of the femur. the condyles bear weight while also allowing movement at the knee

Tibia - intercondylar eminence

in between the condyles

Tibia - tibial tuberosity

ligaments holding the patella in place attach to the tibial tuberosity

Tibia - medial malleolus

the bone on ur ankle that sticks out (but the inner part of ur ankle cause its on your tibia)

\
the distal end of the tibia is an attachment site for ligaments holding the leg and foot bones together at the ankle

**Fibula** bone

How many landmarks does the **Fibula** have? List them

2

head of the fibula

lateral malleolus

Fibula - head of the fibula

the head attaches the fibula attaches the fibula to the proximal end of the tibia

Fibula - lateral malleolus

now this is the bigger bone that sticks out on your ankle (on the outside of your ankle)

\
the distal end of the fibula is an attachment site fo ligaments holding the leg and got bones together at the ankle
